Skin Health and Nutritional Practices

Your skin reflects what is occurring beneath the surface, so when it is inflamed, dry, dull, or aged beyond expectation, it’s a health signal that should not be ignored. And although other aspects, such as genetics, UV exposure, and environmental factors, also play major roles, skin health can be a great place to start a deeper understanding. So let’s break down how to achieve healthy, resilient skin through food, movement, sleep, stress management, and targeted lifestyle practices.

Nutrition

Fats: The skin barrier is largely composed of lipids, including ceramides, cholesterol, and free fatty acids. Dietary fat quality directly influences barrier function. Omega-3 fatty acids (EPA and DHA), found in fatty fish like salmon, sardines, and mackerel, have been shown in randomized controlled trials to reduce transepidermal water loss (TEWL), decrease inflammatory cytokine activity in the skin, and improve conditions like eczema and psoriasis.

• Aim for at least two servings of fatty fish per week, or consider a high-quality fish oil supplement providing at least 1–2g of combined EPA/DHA daily.

Equally important are omega-6 fatty acids, specifically linoleic acid, found in sunflower seeds, hemp seeds, and evening primrose oil. A healthy omega-6 to omega-3 ratio (ideally 4:1) is associated with reduced inflammation, chronic inflammation being one of the primary drivers of accelerated skin aging, acne, and eczema.

Antioxidants: Dietary antioxidants neutralize free radicals, providing a form of internal protection and clean-up service. As UV radiation and environmental pollution generate reactive oxygen species (ROS) that damage skin cell DNA, degrade collagen, and accelerate photoaging, antioxidants assist in counteracting these issues. Especially:

• Vitamin C: Essential for collagen synthesis and a potent free radical scavenger. Found in bell peppers, kiwi, strawberries, and citrus. Vitamin C also regenerates vitamin E in the skin, amplifying total antioxidant capacity.

• Vitamin E: A fat-soluble antioxidant that protects cell membranes from lipid peroxidation. Found in almonds, sunflower seeds, avocado, and olive oil.

• Carotenoids: Beta-carotene (carrots, sweet potato, mango) and lycopene (tomatoes, watermelon) accumulate in the skin and have been shown to reduce UV-induced erythema and oxidative damage. Cooking tomatoes in olive oil increases lycopene bioavailability.

• Polyphenols: Found in green tea, dark berries, pomegranate, and dark chocolate (≥70% cacao). EGCG, the primary polyphenol in green tea, has demonstrated anti-inflammatory and photoprotective effects in multiple human trials.

Protein: Collagen and elastin are the structural proteins responsible for skin firmness and elasticity. Prioritize a variety of complete protein sources such as pasture-raised eggs, wild-caught fish, legumes, and grass-fed beef to maintain adequate levels.

• Per day, focus on 1.6g/kg of body weight (CBW) if BMI is <30; but for BMI 30 or higher, use the weight as if your BMI was 30.

Glycine and proline, amino acids are particularly abundant in collagen-rich foods, are the primary substrates for collagen synthesis. This is one reason we emphasize a top-to-tail approach to food, as different items are rich in different ways. Collagen is found in high quantities in animal skins (chicken, fish, pork rinds), connective-tissue-rich meats (brisket, shank, oxtail), and gelatin.

Combine these with vitamin C-rich foods (citrus, berries, peppers) at the same meal to support collagen formation.

Hydration: It really is the crux of optimal health. For skin, hydration maintains skin turgor, supports the delivery of nutrients to skin cells, and facilitates the removal of cellular waste. Research indicates that increasing daily water intake in individuals with low baseline hydration measurably improves skin thickness and density. The goal is not simply drinking a fixed number of ounces but also maintaining electrolyte balance, fiber intake, and foods with high water content (cucumbers, celery, watermelon, leafy greens) for slow absorption. Aim for pale yellow urine as a practical biomarker of adequate hydration.

• Most typically, one should consume around 60-150 oz/day of fluids, including water, other beverages, and food. On just water alone, you should aim to consume approximately 30-50 oz/day.

Chronic inflammation is a common factor underlying skin issues such as acne, rosacea, eczema, psoriasis, and accelerated skin breakdown. 

One factor that can cause inflammation is frequent, large spikes in blood glucose. Research has shown that consuming high-fiber carbohydrates, such as whole grains, legumes, and fiber-rich vegetables, can help prevent these spikes. Alongside fiber, consuming protein and fats in the same meal can help regulate your blood glucose response and prevent major spikes in blood sugar. 

Minimizing refined carbohydrates (white bread, sugary beverages, processed snacks) can prevent rapid insulin release, which can produce excess sebum and inflame the skin.

Another highly inflammatory item is alcohol. It depletes vitamins A, C, and B-complex, which are critical for skin cell turnover and collagen synthesis. Chronic alcohol consumption has been linked to impaired skin barrier function, increased susceptibility to UV damage, and exacerbation of rosacea and psoriasis.

But inflammation is not the same for everyone. Triggers can occur in different people for different reasons; some struggle with items like dairy, others don’t have any issue, so understanding your unique profile is crucial and can be less complicated with an expert assisting you. 

If you’d like to understand your personal gut-skin connection, we provide an array of tests to help you dive deeper. We can identify issues such as Dysbiosis, an imbalance in gut bacteria, which may trigger chronic inflammation that manifests in the skin. Maintaining a healthy microbiome can assist the gut-skin axis, such as prebiotic-rich vegetables (leeks, garlic, onions, Jerusalem artichokes), fermented foods (kefir, sauerkraut, kimchi, plain yogurt), and polyphenol-rich plant foods. 

Nutrient deficiencies, particularly zinc, iron, vitamin D, B-vitamins, and essential fatty acids, have specific dermatological signs. Testing provides the clarity needed to move from guesswork to targeted intervention. At Apeiron Life, comprehensive bloodwork, micronutrient panels, and gut health assessments can identify the underlying drivers of skin dysfunction specific to your needs.

The wellness industry has convinced many people that glowing skin is primarily a topical problem requiring topical solutions. Or they recommend general supplements touted to target your skin, yet most items like collagen peptides are broken down into amino acids during digestion and your body will send the nutrients where it requires it, not where you desire.

Similarly, fads like juice cleanses marketed as skin detoxes can actually exacerbate issues, such as inflammation, since juicing removes the fiber and leaves a pure sugar hit, spiking your blood glucose and inflammatory response.

Lifestyle changes most beneficial for your skin are also those that support cardiovascular health, cognitive function, metabolic resilience, and longevity.

And finally, don’t forget to rest. Sleep is crucial to your skin's renewal cycle as during deep sleep, growth hormone secretion peaks, driving cellular repair, collagen synthesis, and the turnover of damaged skin cells. Chronic sleep deprivation (less than 6 hours per night) has been directly linked in human studies to increased skin aging, reduced barrier recovery after UV exposure, elevated inflammatory markers, and worsened outcomes in conditions like eczema and psoriasis.
