I've tried countless sunscreens for my face over the years. Recently, I've reached the conclusion that my sensitive skin just cannot tolerate chemical sunscreens. Being on the Regimen, my skin is even more sensitive and vulnerable...and I am desperately searching for a physical sunscreen that works well without causing rashes or breakouts. I am currently using Elta MD facial sunscreen, and it's working pretty well. But it's expensive, and I'm curious if there is something better out there that I've overlooked! What works for you?
