A group of friends (including the guy I like) want me to go swimming with them. I have really light skin and a few active pimples right now because I did manage to clear my pretty severe acne. Now I'm left with these great red marks left all over my face from the acne I had. I pretty much always have makeup on I won't leave my house without it. I cover it up really good to the point where it looks like my skin is clear. I am So scared to go swimming. Is there any way I can keep my foundation on?
