Skin Biology, Skin Layers
- The skin is a layered organ that protects the body physically and chemically. Its thickness and composition vary depending on the body area.
- The outermost layer of the skin is called the epidermis, followed by the dermis, and then subcutaneous fat.
- The dermis contains blood vessels, capillaries, hair follicles, and nerve endings.
- The skin has glands that produce oil, and there are microorganisms living on the skin called microbiota. The skin microbiome acts as a barrier to infections and provides nourishment for healthy-looking skin.
Sun Exposure, UV Light & Skin Cancers; Sunscreen
- UV light from the sun can cause skin cancer by damaging DNA and disrupting cell function. Sunscreens are used to block UV light and prevent skin cancer.
- Red light therapy may be beneficial for skin health, while short-wavelength light may be harmful.
- The effects of sunlight on skin health depend on factors such as dose, timing, and genetic background.
- People have varying levels of natural melanin production, affecting their skin tone, and geographic location plays a role in sun exposure availability.
- Sunscreen usage is often based on recommendations from dermatologists or convenience rather than a thorough understanding of individual needs.
Aging, Sun Exposure, Skin Cancers, Physical Barriers
- Sun exposure can disrupt collagen and elastin in the skin, leading to premature aging, but some exposure is beneficial for hormone production and vitamin D synthesis.
- Excessive sun exposure increases the risk of skin cancer, but not all deadly skin cancers are related to sun exposure.
- Physical barriers like clothing provide good protection from the sun's harmful effects.
- Sunlight is important for setting circadian rhythms, but excessive midday sun exposure should be avoided, and the UV index can be used to determine when extra protection is needed.
Sunburn & Skin Cancers
- Sunburn is an inflammatory reaction in the skin caused by excessive sun exposure.
- Sunburn does not directly cause skin cancer, but it reflects excessive sunlight exposure which can cause skin cell mutations and lead to certain skin cancers.
- Avoiding sunburn is important for preventing accelerated skin aging and reducing the risk of skin cancers.
- Physical barriers like clothing, hats, or bandanas can provide significant protection from the sun.
- Sunscreens are important for protecting the skin from sun damage, including sunburn, skin cancer, and premature aging.
- Sunscreens work by absorbing or reflecting UV radiation from the sun.
- There are two main types of sunscreens: chemical and physical.
- Chemical sunscreens contain ingredients that absorb UV radiation, while physical sunscreens contain ingredients that reflect UV radiation.
- Some chemical sunscreens have been linked to potential health risks, including hormone disruption and skin irritation.
- Physical sunscreens are generally considered safer than chemical sunscreens, but they can be more expensive and may leave a white cast on the skin.
- It is important to choose a sunscreen that is broad-spectrum, meaning it protects against both UVA and UVB rays, and has an SPF of at least 30.
- Sunscreens should be applied liberally and reapplied every two hours, or more often if swimming or sweating.

Vitamin D, Sun Exposure & Sunscreen
- Vitamin D is crucial for bodily and brain functions and is primarily obtained through fortified foods or supplements.
- Measuring vitamin D levels helps determine the appropriate dosage for supplementation.
- Sunscreen and physical barriers do not entirely prevent vitamin D synthesis.
- Sunlight exposure can enhance hormone production, including testosterone and estrogen, leading to improved mood and well-being.
- The skin acts as an endocrine organ, influencing hormone production by communicating with other organs.
- Sunlight affects the vitamin D pathway, impacting the production of testosterone, estrogen, and luteinizing hormone.
- Moderate sunlight exposure positively influences hormone production, promoting overall well-being.
- Insufficient sunlight exposure can result in lower hormone levels, negatively affecting well-being.
- A study provided in the show notes supports the connection between sunlight exposure and hormone production.
Organic (Chemical) Sunscreen & Inorganic (Mineral-Based) Sunscreen
- Sunscreens protect the skin from sun-induced mutations and aging effects.
- Mineral-based sunscreens (zinc oxide or titanium dioxide) are generally considered safer than chemical-based sunscreens, especially for young children.
- Chemical-based sunscreens may contain endocrine disruptors and some studies suggest they can be absorbed into the bloodstream.
- Physical barriers, such as clothing, are the safest option for sun protection.
- Sunscreens with up to 25% zinc oxide concentration are considered safe.
- Zinc oxide sunscreens can be thick and pasty, so titanium dioxide is added to make them silkier and easier to spread.
- Chemical-based organic sunscreens can be problematic at high concentrations due to concerns about endocrine disruption and potential mutagenic effects.
Skin Cancers, Moles, Laser Resurfacing
- Skin cancer, including melanoma and basal cell carcinoma, is a prevalent concern.
- Monitoring moles for changes is crucial, but not sufficient for early detection.
- Persistent pimple-like lesions, seeping spots, or mole changes warrant a dermatologist's evaluation.
- Annual full-body skin checks by a dermatologist are recommended for comprehensive screening.
- Laser resurfacing of the skin, particularly in sun-exposed areas, can reduce the incidence of skin cancers by up to 30%.

Sun Exposure, Melanoma & Life Expectancy
- Sun exposure in moderation, particularly early morning and late afternoon, can positively impact circadian rhythm, mood, focus, alertness, sleep, mental health, immune system function, and feelings of well-being.
- Sunlight exposure to the eyes is particularly effective in setting the circadian rhythm.
- Appropriate sunlight exposure can positively modulate hormone and neuromodulator pathways, leading to improved mental and physical health.
- Avoiding sunlight completely can shorten lifespan, similar to the negative effects of cigarette smoking.
- Excessive sunlight exposure can cause skin cancers, so physical barriers or chemical-based sunscreens should be used for protection.
Tool: Youthful Skin, Collagen & Vitamin C
- Collagen, hydration, and genetics influence skin health and appearance.
- Collagen is a vital protein that provides elasticity and strength to the skin.
- Consuming collagen supplements, particularly hydrolyzed collagen, can selectively improve skin health and appearance by increasing collagen production.
- Collagen supplements can be derived from various sources like fish, animal hooves, and tendons.
- The recommended dosage for collagen peptides is between 15 to 30 grams per day, and it can be further enhanced by taking 500 to 1,000 milligrams of Vitamin C.
- Collagen protein supplementation may also have anti-inflammatory effects and improve the elasticity of the skin barrier.
- Collagen ingestion can increase the chemotaxis and mobility of fibroblasts, contributing to a more youthful skin appearance.
Peptides, BPC-157, Copper
- BPC 157 is a synthetic peptide that aids in tissue and wound repair by increasing angiogenesis and fibroblast motility.
- It is used for post-injury recovery, muscle building, endurance sports, and cosmetic purposes to increase blood flow and tissue repair.
- BPC 157's vascularization effects may occur globally throughout the body, including tumors, so caution is advised when using it for skin health.
- Copper is a trace mineral that plays a role in collagen synthesis and skin rejuvenation, but excessive intake can cause inflammation.
- Many skin rejuvenation products contain copper peptides, BPC-157, or ingredients that promote collagen synthesis.
- BPC-157 has potential risks, including accelerating tumor growth, and its effectiveness lacks support from randomized controlled trials.
- Understanding the risks and mechanisms of these products is crucial before use.
- Ensure adequate dietary copper for DNA repair, collagen turnover, and antioxidant properties, but avoid excessive intake.
Tool: Niacinamide (Nicotinamide), Youthful Skin, Dark Spots, Hyaluronic Acid
- Niacinamide (vitamin B3) improves skin health and appearance by increasing ceramide production, reducing inflammation, balancing oil production, and diminishing hyperpigmentation.
- Niacinamide can be taken orally (500 mg twice daily) or applied topically through ointments or serums.
- Dermatologists recommend consistent use of niacinamide for 3 to 6 months or more for effective results.
- Hyaluronic acid, a natural component of the skin, helps retain moisture and provides a plumping effect.
- Dermatologists and cosmetic surgeons recommend supplementation with collagen, vitamin C, niacinamide, and hyaluronic acid for improving skin health.
Tool: Retinol (Retin-A, Tretinoin, Retinyl Esters), Youthful Skin
- Retinoids, including retinol and prescription drugs derived from vitamin A, are recommended by dermatologists to enhance skin health and maintain a youthful appearance.
- Retinoids work by converting into retinoic acid, which activates transcription factors that stimulate the production of collagen and other essential proteins for new skin formation.
- Starting retinoid use in one's 20s is beneficial, but caution is necessary as they can increase skin sensitivity to light, causing redness or dryness.
- Retinoids improve angiogenesis, vascularization, and skin elasticity by removing degenerated elastin and promoting new skin synthesis.
- Retinoid Esters, available over-the-counter, can be applied to the skin to enhance skin health and appearance, as supported by positive user feedback and the endorsement of cosmetic surgeons and dermatologists.
Tool: Phototherapy, Youthful Skin, Treating Skin Conditions
- Phototherapy using red and near-infrared light can improve skin health and appearance by reducing inflammation, improving mitochondrial function, and increasing blood flow.
- Phototherapy has been shown to be beneficial for various skin conditions such as acne, wound healing, and improving the youthful appearance of the skin.
- The effects of phototherapy tend to be mild to moderate, but they can be significant when combined with other treatments such as injections of BPC-157, hyaluronic acid, or niacinamide.
- Sunlight is a natural source of red and near-infrared light, and it can also provide benefits for skin health.
Tool: Nutrition for Skin Health, Anti-Inflammatory Diets
- Healthy skin is a reflection of a robust immune system.
- The gut microbiome and nutrition are crucial factors in maintaining skin health.
- Consume a diet rich in unprocessed or minimally processed whole foods.
- Prioritize anti-inflammatory diets like the Mediterranean or Paleo diet.
- Include foods rich in vitamins, minerals, micronutrients, and collagen.
- Supplement with omega fatty acids, especially if lacking in your diet.
- Consume fatty fish or fish oil supplements, preferably in liquid form for affordability.
- Eat plenty of dark leafy greens and colored fruits and vegetables, such as oranges and strawberries.
- Obtain vitamin A from dietary sources like oranges, carrots, and sweet potatoes to avoid the risk of overdose.
- Include garlic in your diet for its sulfur content, which is essential for collagen synthesis and repair.
- Refer to Dr. Ronda Patrick's video and other content for more detailed information on nutrition for skin health and appearance.
- Ensure adequate intake of vitamins and minerals regardless of dietary preferences (vegan, vegetarian, omnivore, or carnivore) for optimal skin health.
Highly Processed Foods, Advanced Glycation End Products & Skin Health
- Avoid highly processed foods as they contain advanced glycation end products (AGEs) which are inflammatory and can worsen skin conditions like psoriasis and acne.
- AGEs are formed when sugars and proteins/fats interact at high heat during food processing, making them shelf-stable.
- Consuming processed foods high in sugar and fat can trigger an inflammatory response and aggravate acne.
- The glycemic load of a diet, not just the glycemic index of individual foods, is important in managing acne.
- High glycemic load diets cause high insulin levels and disrupt hormone and cell growth pathways, exacerbating acne.
- Processed foods can accelerate skin aging.
- Many healthy and anti-inflammatory foods are also delicious.
- The myth that fried foods cause breakouts is true due to the pro-inflammatory effects of high-heat cooking.
Tools: Reduce Inflammation: Gut Microbiome, Sleep, Alcohol, Smoking, Stress
- To improve skin health, maintain a healthy gut microbiome by consuming fiber from fruits, vegetables, and fermented foods like kimchi and sauerkraut. Avoid high-sugar fermented foods and those that are shelf-stable at room temperature.
- Prioritize sleep, aiming for 6-9 hours of consistent sleep per night.
- Limit alcohol consumption, as excessive drinking can negatively impact skin appearance and overall health.
- Stay hydrated by drinking plenty of water and electrolytes.
- Avoid smoking and nicotine from all sources, as they can damage the skin and accelerate aging.
- Manage stress through techniques like the physiological sigh, proper sleep, meditation, and non-sleep deep rest (Yoga Nidra) to improve skin health.
- To maintain healthy skin, avoid nicotine use or use it sparingly, and prioritize activities that improve blood flow and reduce inflammation.
Acne, Hormones & Insulin; Tool: Low Glycemic Diet, Dairy
- Acne is a common skin condition affecting up to 90% of young people, caused by a buildup of sebum in hair follicles.
- Hormonal influences, such as increased androgen levels during puberty, and a diet with a high glycemic load or that evokes a large insulin response can worsen acne.
- To improve skin health, reduce stress, get enough sleep, and eat a healthy diet consisting mostly of non-processed, minimally processed foods.
- Avoid excessive sugar and highly processed foods to prevent spikes in insulin and blood glucose levels and reduce the formation of glycation end products.
- Intermittent fasting can be beneficial but should be approached with caution for young people who need adequate nutrients for growth.
- Overconsumption of whey protein and dairy products may contribute to acne, while full-fat dairy might be a better choice than non-fat or low-fat dairy due to the insulin spike associated with emulsifiers in the latter.
- High-fat meals, fried foods, and sugary milkshakes can trigger acne through increased inflammation.
- Reducing or eliminating certain foods can significantly improve acne by lowering inflammation and regulating sebum production.
Tools: Face Cleansing & Acne; Scarring & Popping Pimples
- Adequate sleep, stress reduction, gut microbiome care, and proper nutrition are essential for improving skin health and managing acne.
- Avoid over-cleansing the skin, as it can disrupt the skin microbiome and worsen acne.
- Use a gentle, unscented cleanser twice or three times a day.
- Salicylic acid can help reduce the stickiness of skin cells and prevent pore clogging.
- Avoid popping pimples, as it can worsen inflammation and lead to scarring.
- For severe acne, consult a dermatologist for potential treatments such as corticosteroid injections to reduce redness.
- Dietary changes, lifestyle adjustments, prescription medications, and gentle cleansing can effectively manage acne.
- Some dermatologists have observed positive results in acne patients who exclude highly processed foods and increase their intake of anti-inflammatory foods like fruits, vegetables, meat, fish, and eggs from healthy sources.
Tool: Treating Rosacea, Alcohol, Skin Care, Nutrition
- Rosacea is a skin condition characterized by facial redness caused by genetics, inflammation, and triggers like alcohol consumption.
- To improve skin health and appearance in individuals with rosacea, it is recommended to:
- Adopt a low-inflammation, low-glycemic diet.
- Prioritize adequate sleep.
- Minimize or eliminate alcohol intake.
- Establish a skincare routine that includes lukewarm water, a gentle unfragranced cleanser, and regular sunscreen use.
- Use a quality mineral-based sunscreen for sun protection.
- Apply a moisturizer to maintain skin hydration.
- Consider topical or oral use of nicotinamide (niacinamide) or licorice root for additional treatment.
- Rosacea treatment focuses on reducing inflammation and promoting collagen production.
- It is important to avoid strong astringents and heat-increasing factors like spicy foods, as they can irritate the skin and worsen rosacea symptoms.
Stubborn Rosacea, Over Cleansing, Pulsed Dye Laser
- Stubborn rosacea may be due to excessive use of cleansers.
- Over-cleansing can cause skin issues.
- It is recommended to shower and cleanse with a gentle cleanser as soon as possible after working out to avoid bacteria and skin issues.
- Some rosacea is very stubborn and may not go away even with lifestyle adjustments and medical treatments.
- Angioma, the accumulation of blood vessels near the surface of the skin, can occur in people with rosacea.
- Pulsed dye laser treatment can be used to treat stubborn rosacea and angioma.
Psoriasis Treatment, Immune System & Prescriptions
- Psoriasis is now known to be related to the immune system, not just overproduction of skin cells.
- Prescription drugs that target specific interleukins have proven effective in treating psoriasis.
- Psoriasis is considered an overactivation of the immune system, leading to excessive skin cell production.
- Future episodes will cover various skin health topics not discussed in this episode, such as eczema and Botox.
- Expert guests, including dermatologists and a cosmetic surgeon, will be invited to provide specialized knowledge.
- Cosmetic surgery can also address serious skin conditions, not just improve appearance.
