212. Skincare and sunscreen

Paul Saladino MD podcast

This week, Paul talks all about skin: how to take care of your skin, what you should and should not eat to have healthy, radiant skin, how to heal skin conditions like eczema, psoriasis and acne. He shares why the sun itself is highly beneficial for our skin and overall health, and although the sun deftly is not harming you, your sunscreen may be.
