Dermatologists only look out for your skin, not the whole you that needs unblocked sunshine. They’re afraid one whiff of sunshine will ruin your skin down the road, or that you won’t know to set boundaries such as if you’re under the sun for more than say 1/2 an hour, during peak hours in Miami, use sunscreen.
So I’d love to ignore their advice, but the cosmetics industry has decided to include sun blocking ingredients in almost every product applied to the face.
