I had IPL 5 months ago. Since then my skin has been dehydrated and sensitive to everything except for epiceram. I need to find a sunscreen that my skin will tolerate. I tried Elta UV, Skinceutical UV Defense, and Vanicream for Sensitive skin. So far they all sting and make my skin bump up. Should I tough through the pain and use them anyway? Is it pain preventing the skin from healing? Also, is it common for skin to be this sensitive after IPL?
