I've been trying to acclimate myself to the sun this summer by tanning a little bit. I didn't want to get a sunburn, so when I was out at the beach, I was only there for about 30 minutes or so. I felt fine out there and on the way back, but later in the day my skin started to turn red. I apparently got a little bit of a sunburn. That was a few weeks ago. I let that heal and today laid out by the pool for maybe 15 minutes. Well, I have a bit of a sunburn again. So I have a few questions: 1) I'm worried about premature skin aging, so have these two sunburns irrevocably damaged my skin? The sunburns are pretty mild, but I pride myself on my young appearance, and don't want to get wrinkles or anything. 2) About a year ago I got a pretty bad sunburn on my shoulders from being at the beach. Now, even when I'm laying down, my shoulders get the reddest when I sunburn. Why is that? 3) If I'm trying to get a tan, should I use sunscreen? Or should I just stay in the sun for a very short period of time? It seems to me if I use sunscreen, I basically just have to stay in the sun longer to get a tan. I just want a little bit of a tan. Thanks.
