Episode #243: Beyond Wrinkles: How Your Skin's Microbes Impact Your Health Span with Kiran Krishnan

Could the health of your skin be one of the best predictors of chronic disease risk and mortality?

In today’s episode of The Longevity Podcast, Kiran Krishnan and I discuss how aging and dysfunction of skin, driven by changes in the skin microbiome, may actually precede and contribute to unhealthiness in the body, rather than simply reflecting it. Maintaining your skin's barrier function by supporting a balanced, diverse skin microbiome could be a crucial factor for health and longevity.

Our conversation delves into the science of the skin microbiome, how modern products and lifestyles impact it, and practical strategies to keep your skin's ecosystem thriving. Don't miss this episode, which may forever change how you think about skincare and healthy aging.

Kiran Krishnan is the chief microbiologist at Just Thrive with 20 years of experience in the dietary supplement and nutrition market. He comes from a strict research background, having spent several years with hands-on R&D in the fields of molecular medicine and microbiology at the University of Iowa.

Key Takeaways

• The skin plays a crucial role in longevity and health span, acting as a dynamic barrier and protecting against toxins and pathogens.

• Maintaining the pH of the skin and the ceramide layer is essential for skin health and preventing age-related skin issues.

• Phytoceramides, obtained from plants, can help support the health of the skin and may be beneficial in skincare products. The majority of skin care products are not good for the skin microbiome, but it is not feasible to eliminate their use completely.
