Hi!!  I was on vacation last week and got a really bad sunburn on my first day there. I read on treating sunburns and was very cautious with my sun exposure, but was out in the sun for a few hours 2 days after the initial burn. Now, my skin has turn really dark, as if I got a massive tan. I've started to peel all over my chest and face but I was wondering how long this dark tan would last, because it really isn't pretty.
