I am 15 years old and I am currently on vacation. Whenever I decide to swim,my cheeks be red. It looks like tiny little red points and little red bumps. My skin is usually both dry and oily. My forehead and nose is oily and the rest is dry. So is this about being dry? I am really confused because I don't think that it is soo dry but maybe normal. And also the redness is not permanent,it always become normal after 10-20 minutes ago. But at that time it itch and burn.Also my skin is really sensitive..Can you guess what is that about??
