Has the incision healed? Has the swelling gone down? Can the patient move normally again?

In our latest Mito-Hackers webinar, Dr. Francisco Villarreal looked at recovery from a different perspective:

What is happening inside the body as it responds to the stress of surgery?

His presentation focused on several connected processes, including blood flow, inflammation, tissue repair, muscle function and mitochondrial energy.

Together, they offer a broader way to think about recovery.

Surgery is a controlled injury

Dr. Villarreal described surgery as a form of controlled tissue injury.

Even when a procedure is medically necessary and successful, the body still has to respond to cutting, bleeding, tissue disruption and inflammation.

Recovery therefore involves much more than closing an incision.

The body must control bleeding, restore adequate circulation, activate immune responses, produce new tissue and eventually remodel the repaired area.

Those processes unfold over different periods of time.

Bleeding must be controlled almost immediately. Inflammation develops over the following hours and days. Tissue repair and remodeling can continue for weeks or months.

The goal is not to prevent these responses.

It is to keep them appropriately regulated.

What determines whether recovery goes well?

Dr. Villarreal highlighted several factors that can affect surgical recovery.

Adequate blood flow is essential because recovering tissue needs oxygen and nutrients.

Nutrition matters, particularly adequate protein.

Patients also benefit from controlling underlying conditions such as diabetes, avoiding smoking, sleeping adequately and beginning to move again as soon as medically appropriate.

Inflammation is another part of the equation.

Some inflammation is necessary for healing. But Dr. Villarreal explained that excessive or prolonged inflammation may interfere with tissue repair and contribute to a more difficult recovery.

This becomes especially relevant in older patients and in people who already have conditions associated with impaired circulation, metabolic dysfunction or chronic inflammation.

Why mitochondria matter during recovery

All of these processes require energy.

Mitochondria produce ATP, the form of cellular energy used throughout the body.

During recovery, ATP is required for processes involved in inflammation, tissue repair, collagen production, scar formation and remodeling.

But mitochondria do more than produce energy.

Dr. Villarreal also discussed their relationship with oxidative stress.

Healthy mitochondria normally generate relatively low levels of reactive oxygen species. Damaged or dysfunctional mitochondria, however, may produce less ATP while contributing to higher oxidative stress.

That matters after surgery because tissue injury already activates inflammatory pathways.

Dr. Villarreal therefore described recovery as a balance between energy production, oxidative stress and inflammation.

When those systems remain well regulated, the environment is more favorable for healing and restoration of function.

Recovery also depends on blood flow

Another recurring theme was circulation.

Healing tissue requires a reliable supply of blood, oxygen and nutrients.

New blood vessels may also need to form as damaged tissue is repaired and remodeled.

Dr. Villarreal connected this to endothelial function, the biology of the cells lining blood vessels.

This means mitochondrial health and vascular health are not completely separate questions.

A recovering tissue needs enough energy to perform repair, but it also needs the circulation required to deliver the materials that make repair possible.

Where does (−)-epicatechin fit?

The final part of the presentation examined research involving (−)-epicatechin.

Dr. Villarreal reviewed studies conducted by his research group and collaborators involving several models of injury and impaired function.

These included animal studies involving cardiac injury, kidney injury and spinal cord injury, along with research examining mitochondrial function, muscle and aging.

He described this body of work as providing direct and indirect evidence relevant to some of the biological processes involved in surgical recovery.

That distinction is important.

The webinar was not presenting a clinical trial showing that (−)-epicatechin improves surgical outcomes in patients.

Instead, Dr. Villarreal's argument was based on biological systems that may matter during recovery, including mitochondrial function, cellular energy, vascular function and muscle preservation.

What happens to muscle during inactivity?

The Q&A moved into another problem familiar to many surgical patients: muscle loss during periods of inactivity.

A participant asked whether (−)-epicatechin might be relevant to the muscle deterioration that can occur during prolonged bed rest.

Dr. Villarreal discussed an animal study involving spinal cord injury in which animals receiving (−)-epicatechin showed greater preservation of muscle mass than animals receiving placebo.

He compared this with a familiar example.

When a leg is immobilized in a cast for an extended period, the muscles in that leg become visibly smaller because they are not being used.

That is one reason mobility came up repeatedly during the presentation.

When medically possible, getting patients moving again is an important part of recovery.

Preparing before surgery

The discussion eventually turned to what can be done before a planned operation.

Dr. Villarreal emphasized preparation.

That can include good nutrition, control of existing medical conditions, avoiding smoking, adequate sleep and physical activity when possible.

Exercise presents an interesting challenge.

Someone preparing for a hip or knee replacement may benefit from being physically stronger before surgery, but the condition requiring surgery may also make exercise difficult.

That makes preparation highly individual.

The larger idea was simple:

The condition in which the body enters surgery may influence how well it handles the demands that follow.

Recovery is a whole-body process

Perhaps the clearest message from the webinar was that surgery should not be viewed only through the part of the body being operated on.

A hip replacement involves more than the hip.

A prostate procedure involves more than the prostate.

Recovery requires coordination among circulation, immune responses, inflammation, muscle, metabolism and cellular energy production.

Mitochondria sit within that larger network.

They are not the only factor determining recovery, but they help supply the energy required for many of the processes that allow tissue to repair and function to return.

When Dr. Villarreal was asked what he most wanted viewers to remember, his answer was straightforward:

Be prepared.

When surgery is planned in advance, the weeks and months before the procedure offer an opportunity to improve the condition in which the body enters that challenge.

And from the mitochondrial perspective, recovery begins before the first incision is ever made.

In our recent Mito-Hackers webinar, Zita Desmet asked a different question:

What is actually happening within the skin as it gets older?

Her presentation centered on three connected processes: cellular turnover, communication between cells, and mitochondrial energy.

Together, they offer a different way to think about skin longevity. Instead of focusing only on how old skin looks, the discussion focused on how well skin continues to protect, renew and maintain itself over time.

Skin is constantly balancing defense and renewal

Zita began with two fundamental jobs of the skin.

The first is defense. Skin forms the interface between the body and the outside environment and must continually respond to ultraviolet light, pollution, oxidative stress and other external influences.

The second is renewal. Older and damaged cells must be replaced while the skin maintains an effective protective barrier.

Zita described these processes as a balance. When the skin is continually dealing with outside stressors, more of its resources may be directed toward defense, potentially leaving less capacity for effective renewal.

That tension between protecting the tissue and renewing it became one of the central themes of the webinar.

What happens to cellular turnover as skin ages?

Skin renewal is a continuing biological process.

New keratinocytes are produced near the base of the epidermis. As they move toward the surface, they change in form and function, contribute to the protective barrier and are eventually shed.

Zita described an approximate 28-day turnover cycle in younger skin, with the process potentially extending to 45 to 60 days in older skin.

But faster is not necessarily better.

During the Q&A, Mani asked whether cellular turnover could become too fast. Zita explained that both extremes can be undesirable. Turnover that becomes too slow may interfere with effective renewal, while excessively rapid turnover may not allow cells enough time to mature properly and form an effective barrier.

The goal, in other words, is not maximum turnover.

It is appropriate, well-regulated turnover.

Skin aging goes deeper than the surface

The presentation also looked at the different layers of the skin.

The epidermis forms the outer layer and plays an important role in barrier function and cellular renewal.

Beneath it lies the dermis, where much of the skin's structural support is found.

Zita discussed several components of this environment, including collagen, elastin, hyaluronic acid and fibroblasts.

Collagen receives enormous attention in conversations about skin aging, but the webinar made an important point: collagen does not exist by itself.

It is part of living tissue.

Fibroblasts produce and maintain components of the extracellular matrix. Blood vessels supply the tissue. Cells communicate with one another. Inflammatory processes, oxidative stress and changes elsewhere in the body can influence the environment in which those cells operate.

Looking only at collagen therefore tells us only part of the story.

From collagen to cellular communication

This broader view led into another theme from Zita's presentation: communication between cells.

Healthy tissue depends on cells being able to respond to their surroundings and to signals from other cells.

During aging, Zita discussed several processes that may interfere with that environment, including glycation, oxidative stress, inflammation and cellular senescence.

She also introduced the concept of “inflammaging” and discussed how senescent cells can remain within tissue while influencing the cells around them.

Rather than looking at each of these processes in isolation, Zita's presentation placed them within the larger question of whether aging skin can continue to communicate, repair itself and respond appropriately to stress.

That leads to another question:

Where does the energy required to do all of this come from?

Mitochondrial energy and skin longevity

Mitochondria are usually discussed in relation to metabolism and energy production, but Zita argued that they also deserve more attention in conversations about skin aging.

Her reasoning was straightforward.

Cells require energy to function.

Renewal requires energy. Repair requires energy. Maintaining the skin barrier requires energy. Responding to environmental stress and communicating with surrounding cells also require functioning cellular machinery.

Zita therefore placed mitochondrial energy alongside cellular turnover and communication as one of the foundations of her skin-longevity framework.

The presentation discussed several approaches intended to influence mitochondrial function in skin, including photobiomodulation, supplementation and targeted topical delivery. High-purity (−)-epicatechin was also discussed within this context.

But the larger idea went beyond any one intervention.

Rather than asking only what can be applied to the surface of the skin, Zita encouraged the audience to think about the condition and capacity of the cells underneath it.

Building metabolic resilience

Zita used the term metabolic resilience to describe the ability of skin cells to continue functioning despite the stresses they encounter.

She grouped some of these challenges into broad categories that included sugar-related stress, oxidative stress and external environmental stress.

Skin is exposed to these pressures repeatedly throughout life.

The question therefore becomes less about eliminating every source of stress and more about whether the tissue can continue to defend itself, recover and renew.

This changes the way we think about skin longevity.

A wrinkle is something we can see.

The biological processes that eventually contribute to it may have been developing for years beneath the surface.

The Q&A went beyond the presentation

The audience discussion took several of these ideas further.

Dr. Francisco Villarreal expanded on the relationship between collagen, fibroblasts, inflammation, oxidative stress and the tissue environment, including the importance of blood flow and microcirculation.

The group also discussed what happens when common skincare practices become too aggressive and potentially interfere with the skin barrier.

A question about microneedling led to a broader conversation about controlled stress, tissue repair and whether the condition of the underlying cells affects the response to an intervention.

And near the end of the Q&A, Zita was asked a particularly practical question:

If you wanted your skin to function as well as possible 20 years from now, what three things would you prioritize today?

Her answer brought the conversation back to many of the themes that had appeared throughout the webinar.

We will leave that answer for the recording.

From “anti-aging” to skin longevity

Perhaps the clearest summary of Zita's framework came at the end of her presentation:

Turnover + communication + mitochondrial energy = cell longevity.

That equation captures the difference between the traditional language of “anti-aging” and the idea of skin longevity.

Anti-aging often begins with something visible and asks how we can change it.

Skin longevity asks a more basic set of questions.

How effectively are skin cells renewing?

Are they communicating properly?

Can the tissue respond to stress and repair itself?

Do those cells have the energy needed to continue doing their jobs?

Seen this way, skin aging is not simply about how many wrinkles appear on the surface.

It is about how well living tissue continues to function as it gets older.

Which part of the presentation deserves the most attention: mitochondrial function in skin, oxidative stress, vascular support, the measurement methods, or the early topical epicatechin findings?

Interested in joining Mito-Hackers? Learn more about the community and apply for access to participate in future webinars and scientific discussions.

This briefing is intended for educational and scientific discussion only. It should not be interpreted as medical advice, diagnosis, or treatment guidance.

His presentation examined a practical question that grew out of earlier epicatechin research: Could a compound studied in relation to mitochondrial and vascular biology also influence measurable features of aging skin when applied topically?

Skin Aging Is More Than a Surface Problem

Dr. Ceballos described skin aging as the combined result of intrinsic and extrinsic factors. Intrinsic aging includes time-dependent changes in DNA stability, immune regulation, metabolism, and cellular repair. Extrinsic factors include ultraviolet exposure, smoking, radiation, and excessive alcohol use.

These influences can increase oxidative stress and place additional strain on mitochondria and other cellular systems. Over time, reduced repair capacity and continued molecular damage may contribute to visible changes such as wrinkles, uneven pigmentation, and loss of smoothness.

The central point was not that mitochondria are the only drivers of skin aging. It was that the skin is living, energy-dependent tissue, so its appearance cannot be separated completely from cellular function.

Why Mitochondria Matter in Skin

Mitochondria provide ATP, the usable energy cells need for maintenance, repair, signaling, and normal tissue function. They also participate in oxidative signaling and interact with vascular and endothelial systems that help supply tissues with oxygen and nutrients.

Dr. Ceballos reviewed earlier work in muscle and vascular biology that led his team to ask whether some of the same epicatechin-related pathways might also be relevant in skin. That earlier research provided the rationale for the skin work, but it did not by itself prove that a topical formulation would change skin appearance. The topical question had to be tested directly.

Why Study (−)-Epicatechin Topically?

(−)-Epicatechin is a flavanol studied in connection with receptor-mediated cellular signaling, mitochondrial biology, vascular function, and oxidative balance. Dr. Ceballos explained that the team developed a topical formulation so the compound could be studied directly at the skin rather than assuming that findings from oral or systemic research would automatically translate to topical use.

This work contributed to the development of Mitozz RS, a topical cosmetic serum formulated with 98% pure (−)-epicatechin.

How the Skin Study Was Conducted

The presentation described exploratory work involving both the hands and face. The epicatechin-containing serum was compared with a matching formulation without epicatechin, and changes were followed over periods of approximately four to eight weeks.

For the hand measurements, dental casts were used to help reproduce positioning and reduce inconsistencies between images. The researchers also used three-dimensional surface profilometry to measure features such as wrinkle height, valley depth, and the total surface profile.

For the facial examples, a placebo period was followed by use of the epicatechin formulation. The combination of standardized imaging and quantitative surface measurements was intended to evaluate skin texture more objectively than photographs alone.

What the Researchers Reported

In the examples presented, the placebo period produced little visible or measured change. After the epicatechin formulation was introduced, the researchers reported reductions in measured wrinkle height and valley depth, producing a smoother surface profile.

“Wrinkles do not disappear; they decrease in height.”

That distinction matters. The presentation did not show that skin aging had been reversed or that wrinkles had been erased. It showed that specific surface measurements became less pronounced in the examples analyzed.

These findings are best understood as exploratory evidence that supports further study. They should not be treated as the equivalent of a large, independently replicated clinical trial.

What the Q&A Added

The discussion after the presentation addressed several practical and scientific questions:

• Time course: The examples presented showed changes over roughly one to two months, with consistent use described as important.

• Daily routine: Dr. Ceballos discussed allowing the serum to dry before applying other products and continuing to use sun protection during the day.

• Formulation: Epicatechin was the active variable under discussion, while the serum base included other ingredients needed for stability and cosmetic use.

• Local versus systemic use: A topical product is intended to act at the skin and should not be assumed to produce the same systemic exposure as an oral formulation.

• Concentration: More is not necessarily better. Dr. Ceballos described receptor-mediated effects as operating within a response window rather than increasing indefinitely with dose.

• Future questions: Pigmentation, inflammatory skin conditions, and other possible applications remain areas for further research rather than established cosmetic claims.

Cosmetic Use Versus Future Medical Research

Near the end of the presentation, Dr. Ceballos briefly discussed exploratory observations that could justify future medical research involving topical epicatechin. He also stated that controlled clinical trials would be needed before drawing conclusions about therapeutic uses.

Those possibilities remain research questions. They should not be presented as current uses of Mitozz RS, which is a topical cosmetic serum intended to hydrate and condition the skin while helping improve the appearance of fine lines and supporting smoother, more even-looking skin.

The Main Takeaway

The presentation connected visible skin aging with the energy, signaling, vascular, and repair systems operating beneath the surface. Its strongest contribution was not the idea of another “anti-aging ingredient,” but a testable biological question supported by measurable changes in skin-surface geometry.

The findings suggest that topical (−)-epicatechin deserves further study in relation to the appearance of wrinkles and skin texture. They do not show that it reverses aging, erases wrinkles, or treats a medical skin condition.

His presentation examined an emerging question in endometriosis research: Could mitochondrial dysfunction and altered cellular energy help explain parts of the disease that cannot be understood through hormones alone?

Endometriosis Is More Than a Hormonal Condition

Endometriosis has traditionally been viewed primarily as a hormone-related disease. Dr. Upadhyaya did not argue that hormones are unimportant. Instead, he described endometriosis as a multifactorial condition involving several interacting biological processes, including:

• Hormonal signaling

• Genetics

• Immune dysfunction

• Inflammation

• Oxidative stress

• Mitochondrial dysfunction

His central point was that mitochondria do not replace hormones in the endometriosis story. They may help explain how cells respond to hormonal and inflammatory signals.

Looking at both systems together may offer a more complete way to think about why endometriosis develops, persists, and affects women differently.

Why Mitochondria Matter

Mitochondria are usually introduced as the structures that produce cellular energy in the form of ATP. Dr. Ram described their role more broadly, discussing their involvement in:

• Cellular energy production

• Cell survival and repair

• Oxidative stress

• Inflammatory signaling

• Immune function

• Hormonal responses

He also discussed the balance between mitochondrial biogenesis, the production of new mitochondria, and mitophagy, the removal of damaged mitochondria.

When damaged mitochondria accumulate or cellular energy production falls, cells may have greater difficulty maintaining normal repair, communication, and immune regulation.

From Oxidative Stress to Inflammation and Pain

During the presentation, Dr. Ram outlined a possible cycle connecting oxidative stress, mitochondrial damage, inflammation, and pain.

In this model, oxidative stress can damage mitochondrial structures and interfere with energy production. Reduced cellular energy may then impair repair processes, while continued immune activation changes the environment around the affected tissue.

As inflammation persists, tissue damage, new blood-vessel formation, scar tissue, and nerve sensitization may contribute to continuing or worsening pain.

Dr. Ram stressed that pain should not be treated as an isolated symptom:

“Pain is not simply a symptom. Pain is a whole biology.”

This may help explain why the pain associated with endometriosis can be persistent and why reducing pain alone does not necessarily address all the biological processes involved.

Endometriosis, Cellular Energy, and Fertility

Dr. Ram also used reproductive biology to illustrate why cellular energy matters to women’s health.

He discussed the high energy demands associated with egg development, fertilization, pregnancy, and placental function. He described hormones and mitochondria as interconnected systems: hormones influence mitochondrial activity, while mitochondria provide the energy cells need to respond to hormonal signals.

This relationship may be especially relevant when considering endometriosis, infertility, reproductive aging, and the physical and emotional burden experienced by women seeking fertility treatment.

Common Myths About Endometriosis

Near the end of the presentation, Dr. Ram addressed several common misconceptions.

Myth 1: Endometriosis is just painful periods

He described it as a chronic inflammatory condition that may also be associated with infertility, fatigue, pelvic pain, pain during intercourse, and symptoms extending beyond menstruation.

Myth 2: Endometriosis is exclusively hormonal

Hormones are involved, but Dr. Ram also discussed the possible contributions of genetics, immune dysfunction, inflammation, oxidative stress, and mitochondrial dysfunction.

Myth 3: Surgery cures endometriosis

Surgery may remove lesions and relieve symptoms, but Dr. Ram noted that lesions and symptoms can recur after surgery.

Myth 4: More pain always means more extensive disease

The severity of pain does not necessarily correspond to the visible number or extent of endometriotic lesions.

Myth 5: Nothing new is happening in endometriosis research

Dr. Ram pointed to emerging work involving mitochondrial biology, immunology, immunotherapy, multiomics, and precision medicine.

Looking Toward a Broader Understanding

The presentation did not suggest that mitochondrial dysfunction is the sole cause of endometriosis. Instead, Dr. Ram presented it as one possible contributor within a much broader biological system.

Understanding how cellular energy interacts with hormones, inflammation, oxidative stress, immune function, and pain may help researchers ask new questions about the disease.

Dr. Ram described hormones and mitochondria as a kind of “twin engine,” with each system supporting the other. Hormones help regulate and protect mitochondrial function, while mitochondria provide cellular energy and support the production of steroid hormones. The first step in steroid hormone synthesis begins inside the mitochondria, making their relationship reciprocal rather than one-directional.

Hormones tell cells what to do, but mitochondria give those cells the energy to do it.

This energy relationship is only part of the connection. Mitochondria also support steroid hormone production, while hormones help regulate mitochondrial health and activity.

Considering both systems together may help provide a fuller understanding of endometriosis and the health challenges women experience.

This briefing is intended for educational and scientific discussion only. It should not be interpreted as medical advice, diagnosis, or treatment guidance.

The session examined how the evidence for (−)-epicatechin compares with that available for other compounds commonly associated with mitochondrial health.

Rather than relying on a single experiment or outcome, Dr. Villarreal reviewed the evidence across several levels, including pharmacology, molecular mechanisms, preclinical research, human studies, large population studies, and longevity research. A central theme was that compounds should be evaluated by the breadth, consistency, and quality of the research behind them, not simply by their popularity or marketing claims.

The Q&A covered supplement purity and dosing, how (−)-epicatechin is absorbed and metabolized, safety considerations, and its relationship to mitochondrial function and oxidative stress.

For those interested in taking a deeper look, our Supplement Comparison page examines how (−)-epicatechin compares with other commonly discussed compounds across evidence, mechanisms, safety, and practical use.

The video recording will be added to the Webinars & Events space soon.

For now, we’d love to hear from you:

Which type of evidence matters most to you when evaluating a supplement: biological mechanisms, human trials, long-term population data, or something else?

We covered how healthy aging relates to mitochondrial function, vascular health, physical capacity, and the science behind (−)-epicatechin. One key theme was that healthy aging is not just about living longer. It is about maintaining the capacity to move, recover, think clearly, and stay active over time.

Dr. Ceballos also discussed the connection between exercise, mitochondrial function, and (−)-epicatechin as part of a broader conversation about supporting cellular energy and long-term physical capacity.

The video recording will be added to the Webinars & Events space soon.
