A Surgeon's Case for Olive Oil as Daily Skin Care

As a fellowship-trained oculoplastic and reconstructive surgeon, USC clinical professor, researcher, and founder of Mendora, I have spent more than two decades studying how facial tissues heal, age, and regenerate. Throughout my career, I have performed thousands of surgical and non-surgical facial rejuvenation procedures, evaluating tissue quality, inflammation, collagen integrity, and wound healing on a daily basis. One lesson has remained remarkably consistent: healthy, resilient skin is not created solely by what you apply to the surface. It is largely determined by the quality of the biological building blocks your body receives from within.

Patients are often surprised when I tell them that some of the most important decisions affecting their skin happen in the kitchen rather than the bathroom. While advanced skincare products, lasers, and regenerative treatments can produce meaningful improvements, they work best when the underlying tissue is healthy. In surgery, we see firsthand how nutrition influences recovery, inflammation, tissue strength, and long-term skin quality. Individuals who consistently follow nutrient-dense, anti-inflammatory dietary patterns often demonstrate healthier tissue characteristics than those who do not. This observation has shaped much of my philosophy at Mendora, where we focus not only on what goes on the skin, but also on what helps the body continuously repair and rebuild it.

One of the most powerful examples is extra-virgin olive oil. A cornerstone of the traditional Mediterranean diet, olive oil has been extensively studied for its antioxidant, anti-inflammatory, and cardiovascular benefits. Less frequently discussed is its potential role in supporting skin health. Rich in polyphenols, vitamin E, and heart-healthy monounsaturated fats, high-quality extra-virgin olive oil provides many of the nutrients that help protect skin from oxidative stress while supporting the cellular processes involved in repair and regeneration.

When I evaluate skin aging in my practice, I am looking at much more than wrinkles. I assess elasticity, hydration, tissue thickness, vascular health, inflammation, and overall skin resilience. These factors are influenced by genetics and environmental exposure, but they are also affected by long-term nutritional habits. For patients seeking healthier skin, olive oil is one of the simplest evidence-supported additions they can make to their daily routine.

Five Ways Olive Oil Supports Healthier Skin

1. Supports the Skin's Defense Against Environmental Damage

Every day, skin is exposed to ultraviolet radiation, pollution, toxins, and other environmental stressors that generate free radicals. Over time, these free radicals contribute to collagen breakdown, loss of elasticity, uneven pigmentation, and visible aging.

Extra-virgin olive oil contains powerful antioxidants, including vitamin E and polyphenols, which help neutralize oxidative stress. While olive oil is not a substitute for sunscreen or proper skincare, regular consumption may help support the body's natural defense systems and preserve the structural proteins that keep skin firm and resilient.

2. Helps Maintain a Healthy Skin Barrier

One of the most common complaints I hear from patients is that their skin suddenly feels thinner, drier, or more reactive than it did in previous years. In many cases, the skin's protective lipid barrier has become compromised.

Olive oil contains monounsaturated fats, particularly oleic acid, that support healthy cell membranes and help maintain the skin's natural moisture barrier. This becomes increasingly important during hormonal transitions such as perimenopause and menopause, when changes in estrogen levels can contribute to dryness and increased skin sensitivity.

3. Supports a Balanced Inflammatory Response

Many visible signs of skin aging are influenced by chronic low-grade inflammation. Persistent redness, irritation, delayed healing, and increased sensitivity are often manifestations of inflammatory processes occurring beneath the surface.

The polyphenols found in extra-virgin olive oil have been studied for their ability to support a balanced inflammatory response. Replacing highly processed fats with olive oil may help create a healthier internal environment that allows skin cells to repair and regenerate more effectively.

4. Promotes Long-Term Tissue Quality

As a surgeon, I view skin health as a long-term investment rather than a short-term cosmetic goal. Healthy tissue develops over years of consistent habits.

Topical skincare products can deliver important benefits, but they cannot fully compensate for poor nutrition. Over time, nutrient-rich dietary choices help support collagen production, cellular repair, hydration, and overall tissue quality. The cumulative effect often becomes visible through improved texture, elasticity, and resilience.

5. Supports the Gut-Skin Connection

Emerging research continues to strengthen our understanding of the relationship between gut health and skin health. The gastrointestinal tract and the skin communicate through complex immune, hormonal, and inflammatory pathways.

A diet rich in minimally processed foods, healthy fats, and plant-derived nutrients supports a healthier gut environment. Extra-virgin olive oil can play an important role in this dietary pattern, helping to support overall wellness while contributing to healthier-looking skin.

A Surgeon's Recommendations for Choosing Olive Oil

Not all olive oils provide the same nutritional value. When selecting an extra-virgin olive oil, I recommend focusing on three key factors:

• Fresh harvest dates
• Transparent sourcing
• High polyphenol content

Generally speaking, the stronger and more peppery the finish, the higher the concentration of beneficial polyphenols.

The Mendora Perspective

Throughout my years in surgery and regenerative medicine, I have learned that aging accelerates when repair mechanisms slow down. The goal is not simply to mask aging but to continuously support the body's ability to rebuild healthy tissue. Food is not a replacement for an effective skincare regimen. However, it remains one of the most overlooked components of long-term skin health. High-quality extra-virgin olive oil and a repair-focused skincare strategy are working toward the same objective: stronger, healthier, more resilient tissue.

At Mendora, that philosophy guides everything we create. Healthy skin begins long before a product touches the surface.

Mendora's recommendations: high-phenolic extra-virgin olive oils

The following extra-virgin olive oils are widely recognized for their high polyphenol content, transparent sourcing, and overall quality. These top-rated, lab-verified options are excellent choices for those seeking the antioxidant benefits of high-phenolic olive oil.

Expert tips: how to consume, choose and store

• Consume: Taking a shot of olive oil (a tablespoon portion) one or two times per day has become a popular habit in the health-conscious community. However, you can also go the old fashioned route and drizzle it over your dishes, from salad to avocado toast to fish.
• Look for harvest dates. Do not rely on Best By dates alone. Freshness is the most critical factor in maintaining polyphenol content, so aim for oils harvested within the last year.
• Avoid the countertop. Polyphenols degrade quickly under heat and light. Store oil in a cool, dark place, never near your stove, and use the bottle within four to six weeks of opening for maximum benefit.
