Lifespan with Dr. David Sinclair The Science of Looking Younger, Longer | Episode 6
Epidermal Thinning and Aging
- Epidermal thinning is a common effect of aging, accelerated by menopause.
- It's not just a cosmetic issue, but a health concern, increasing vulnerability to injuries and infections.
Foot Ulcers and Epidermal Thinning
- David Sinclair recounts meeting David Armstrong, a leading foot ulcer surgeon.
- Armstrong's work highlights the severe health consequences of epidermal thinning in older adults, including amputation and even death.
Sun Protection
- Protect your skin from excessive sun exposure to prevent accelerated aging.
- Get some sun daily, but avoid sunburn by using sunscreen and limiting exposure time.
In Episode 6 of the Lifespan podcast, Dr. David Sinclair and co-host Matthew LaPlante discuss cosmetic aging and how to improve skin, nails, and hair. They talk about why superficial aging occurs and how external signs of aging are often a reflection of biological age. The latest science behind various beautifying therapies is highlighted, including newer interventions like low-level laser therapy and platelet-rich plasma injections.
