I had bad skin in highschool, I used to wear loads of foundation to cover it up. I once got referred to as the "orange spotty one"
The worst thing was being quite shy I was was really aware of it, even though it may not have seemed so bad to everyone else I would imagine that when they were talking to me they were looking at my 'friend' also.
I used to spend a lot on posh formulas and lotions with salycilic acid and benzoyle peroxide but they aggravated my skin.
Most teenagers go through acne at some point, thinking about it now the pill did calm mine down however I think it was starting to calm down alone beforehand. I still get flare ups now and again. Thats down to my skin being fairly oily, but just think - Less wrinkles in the future!
