How to Improve Skin Health & Appearance

Episode 183 Jul 1, 2024 2h 27m 33 insights
In this episode, I discuss skin health and appearance and why both are important indicators of the health status of your immune system, gut microbiome, and other organ systems. I explain why sunlight is essential for skin and hormone health and how excessive sunlight can accelerate skin aging and cause certain skin cancers. I discuss the different types of sunscreens (physical, chemical, and mineral-based) and potential health concerns of the chemicals found in some (but not all) sunscreens. I also discuss the importance of getting your skin (and not just moles) checked for pre-cancerous and cancer growths, the role of nutrition and lifestyle factors that improve skin health and appearance, and how to improve your skin by reducing local and systemic inflammation and supporting your microbiome.  I explain what works to improve your skin's youthfulness and appearance, including reducing wrinkles, sagging, and pore size. I review the data on ingesting (or topically applied) collagen, vitamin C, niacinamide, hyaluronic acid, and retinol, and what is known about the use of peptides (e.g., BPC-157, copper peptides) and red and far-red light phototherapies for improving skin health and appearance. I also discuss the causes of acne, rosacea, and psoriasis and explain nutritional, skin care, and prescription-based approaches to treating these common skin conditions. This episode ought to help everyone better understand the biology of the skin and help them make the best possible decisions for their skin health, care, and appearance according to age, goals, and current skin conditions.

Actionable Insights

1. Prioritize Consistent, Quality Sleep

Get adequate and consistent sleep (6-9 hours) nightly to dramatically improve skin appearance, health, and vibrancy, as sleep deprivation negatively impacts skin.

2. Implement Stress Management Techniques

Actively manage stress through real-time tools like the physiological sigh and daily practices such as meditation or non-sleep deep rest (yoga nidra) to reduce cortisol and adrenaline, which otherwise cause vasoconstriction, reduced blood flow, and exacerbate skin issues like flushing and breakouts.

3. Prioritize Whole, Minimally Processed Foods

Base 75-100% of your diet on non-processed or minimally processed whole foods (fruits, vegetables, lean proteins) to reduce inflammation and avoid advanced glycation end products (AGEs) that accelerate skin aging and worsen conditions.

4. Cultivate a Healthy Gut Microbiome

Consume sufficient fiber from fruits and vegetables, and 1-4 servings daily of low-sugar fermented foods (e.g., kimchi, refrigerated sauerkraut/pickles) to reduce overall body inflammation, which positively impacts skin health and appearance.

5. Minimize or Eliminate Alcohol Consumption

Reduce or completely eliminate alcohol intake, as it is a pro-inflammatory agent that exacerbates most skin issues, causes puffiness, and negatively impacts sleep and the gut microbiome.

6. Avoid Nicotine Products

Refrain from smoking, vaping, dipping, snuffing, or using any other nicotine products, as nicotine is a vasoconstrictor that accelerates skin aging and increases inflammation, severely harming skin health and appearance.

7. Balance Sun Exposure for Health

Get some sun exposure for vitamin D, hormone production (testosterone, estrogen), and overall brain/body health, but avoid excessive exposure to prevent accelerated skin aging and certain skin cancers.

8. Avoid Sunburn

Prevent sunburn by any means possible (physical or chemical barriers) as it reflects excessive UV exposure, which increases the risk for certain skin cancers and accelerates skin aging.

9. Utilize Physical Sun Barriers

Wear physical barriers like shirts, hats, or jackets to protect skin from sunburn and accelerated aging, as these are universally accepted as safe and effective.

10. Choose Mineral-Based Sunscreen

Opt for mineral-based sunscreens containing zinc oxide and/or titanium dioxide (up to 25% concentration) as they are generally considered safe and reflect UV light, avoiding potential endocrine disruptor concerns of chemical sunscreens.

11. Monitor UV Index for Sun Safety

Check the UV index, especially between 10 AM and 4 PM when it’s typically highest, to determine when extra caution (physical or chemical barriers) is needed to protect skin.

12. Annual Dermatologist Skin Check

Get all of your skin, including moles, checked by a board-certified dermatologist at least once per year to protect against sun-induced and other forms of skin cancer.

13. Promptly Check Persistent Skin Lesions

If you have a pimple-like lesion or any spot on your skin that lasts more than a month, or an area that is seeping plasma, pus, or blood, get it checked by a dermatologist immediately.

14. Supplement with Hydrolyzed Collagen & Vitamin C

Ingest 15-30 grams of hydrolyzed collagen peptides daily, ideally with 500-1000 mg of Vitamin C, to improve skin elasticity, reduce wrinkles, and enhance overall youthful appearance over 3-6 months.

15. Supplement with Niacinamide for Skin Health

Take 500mg of niacinamide (Vitamin B3) twice daily, or use topical serums with 2-10% concentration, to increase skin moisture, reduce inflammation, balance oil production, and minimize hyperpigmented spots and large pores over 3-6 months.

16. Consult Dermatologist for Retinoid Treatment

If not pregnant or breastfeeding, discuss prescription retinoids (e.g., Tretinoin/Retin-A) with a dermatologist to stimulate collagen, improve vascularization, and induce new skin synthesis for a more youthful appearance, carefully managing light sensitivity and potential dryness.

17. Incorporate Red Light/Near-Infrared Phototherapy

Use red light and near-infrared phototherapy for 10-15 minutes, 5-7 days per week, at 1-2 feet distance, to reduce inflammation, improve mitochondrial function, enhance blood flow, and potentially improve skin’s youthful appearance and conditions like acne.

18. Practice Gentle, Regular Skin Cleansing

Cleanse skin 2-3 times daily with a gentle, unscented, unfragranced cleanser and lukewarm water, avoiding harsh cleansers or extreme water temperatures, to support the skin microbiome and prevent exacerbating acne.

19. Never Pop Pimples to Prevent Scarring

Avoid popping pimples at all costs, as it causes mechanical disruption and leads to permanent indentation scars due to matrix metalloproteases eating away at the extracellular matrix; instead, use corticosterone cream to reduce redness and swelling.

20. Manage Rosacea with Lifestyle & Gentle Care

Treat rosacea by consuming a low-inflammation, low-glycemic diet, ensuring adequate sleep, minimizing or eliminating alcohol, using lukewarm water with a gentle cleanser, applying mineral-based sunscreen, and regularly moisturizing with a gentle cream.

21. Consult Dermatologist for Psoriasis Treatment

For psoriasis, consult a dermatologist about prescription drugs that target specific interleukins (e.g., IL-17, IL-23), as these are highly effective in treating this immune system over-activation condition.

22. Shower Promptly After Workouts

Take a shower and cleanse with a gentle cleanser as soon as possible after workouts or sweating to remove bacteria and prevent skin issues, especially acne.

23. Consider Laser Resurfacing for Cancer Prevention

Discuss laser resurfacing with a dermatologist to disrupt and regenerate the epidermal layer, which can reduce the incidence of certain skin cancers by up to 30% and improve skin’s youthful appearance.

24. Optimize Diet with Key Skin Nutrients

Ensure adequate intake of omega fatty acids (from fish, nuts, seeds), dark leafy greens, folic acid, and Vitamin A (from food sources like carrots, sweet potatoes, and berries) to support DNA repair, collagen synthesis, and overall skin health.

25. Use Hyaluronic Acid for Skin Moisture

Apply topical hyaluronic acid or use products containing it to act as a humectant, helping to lock in moisture and give skin a plump, smooth, and youthful appearance.

26. Avoid Rosacea Triggers

Steer clear of strong astringents, excessively hot or spicy foods, and anything that acts as a strong vasodilator, as these can irritate the skin and exacerbate rosacea.

27. Experiment with Dairy & Whey Intake for Acne

If experiencing acne, consider reducing or experimenting with eliminating dairy (especially non-fat/low-fat due to emulsifiers) and whey protein intake, as these can sometimes exacerbate acne by spiking insulin.

28. Avoid Chemical Sunscreen on Young Children

Do not use chemical-based sunscreens on children younger than six months of age, as their skin can easily absorb substances transdermally.

29. Get Morning Sunlight for Circadian Rhythm

Expose eyes to low solar angle sunlight early in the day (when UV index is very low) to set circadian rhythm, which improves mood, focus, alertness, and sleep, positively impacting overall health and lifespan.

30. Consume Collagen-Rich Foods

Include collagen-rich foods like bone broth in your diet to naturally support collagen synthesis and skin rejuvenation.

31. Ensure Adequate Dietary Copper Intake

Make sure your diet includes sufficient trace mineral copper, which is key for DNA repair, collagen synthesis, and reducing reactive oxygen species in the skin, but avoid excessive supplementation.

If recommended by a dermatologist, apply topical salicylic acid to clean skin to reduce keratinocyte stickiness, prevent pore clogging, and decrease swelling associated with acne.

33. Support Skin Microbiome with Cleansing Choices

Wash skin with certain substances and avoid others to support the skin microbiome, which acts as a barrier to infections and nourishes the skin.
