Why This Matters to Us:
As longevity enthusiasts, preserving skin health is a pivotal component of holistic well-being. Skin not only serves as a barrier against environmental threats but also as a reflection of overall health. Understanding how to protect and rejuvenate the skin can significantly impact one's lifespan and quality of life. Dr. Soleymani’s insights offer practical wisdom to help combat aging and improve overall skin health, aligning perfectly with our goals of living longer, healthier lives.
The Detail:
The discussion in a recent episode of the Huberman Lab Podcast with Dr. Teo Soleymani, a renowned dermatologist from UCLA, explored practical strategies for enhancing skin health. One of the focal points was the importance of using mineral-based sunscreens. These sunscreens, made with ingredients like zinc oxide and titanium dioxide, serve as a physical barrier against harmful UV rays, unlike chemical sunscreens that can absorb into the skin and potentially cause unknown health effects.
Furthermore, Dr. Soleymani introduces the concept of an "internal sunscreen" through the use of polypodium supplements. Polypodium leucotomos, an Amazonian fern extract, has been demonstrated to reduce inflammation caused by UV exposure. The supplement's efficacy is particularly noteworthy in light-skinned individuals, and it is suggested to be used in conjunction with topical sunscreens for enhanced protection. Dosages between 50 mg to 480 mg have shown positive results.
Another key component discussed is the use of retinoids, a family of vitamin A analogues. Unlike retinol, off-the-shelf retinoid versions can accelerate skin cell renewal, improve collagen production, and decrease skin cancer risk. They help replace the skin’s top layer more quickly, fostering both a healthier appearance and biological health.
The conversation also highlighted the role diet plays. Consuming a diet rich in complete proteins, such as those found in salmon and dairy, alongside plant-based combinations like rice and beans, ensures all essential amino acids necessary for skin health. Additionally, an anti-inflammatory diet, low in refined sugars and rich in minimally processed foods, further supports skin vitality by minimizing inflammation.
Lastly, Dr. Soleymani emphasized lifestyle factors such as managing stress, reducing nicotine and alcohol intake, and avoiding excessive skin washing. These practices further support maintaining healthy skin and by extension, overall longevity.

In a world overflowing with skincare advice, Dr. Soleymani provides a science-backed route to maintaining radiant skin. By employing strategies like mineral-based sunscreens, polypodium supplements, and retinoid treatments, alongside a nutrient-rich diet, we can significantly bolster our skin's defenses and enhance our longevity. Understanding and implementing these insights are crucial steps toward achieving long-lasting health and vitality.
