sunscreen breaks out my skin horribly :(
Oh boy. That's too bad. It may just be that you've used the wrong brand. There are some good ones out there that are gentle on the skin. Aveeno, Cetaphil, Eucarin, and Oil of Olay...(and if you'd like to save money, just get the drugstore version of these brands of sunscreen...the formulation is basically the same).
If that doesn't work, then I'd suggest a trip to the dermatologist because sunscreen goes a long way towards combating wrinkles.
