Old Acne

I thought once you left puberty, acne left also! Maybe since I didn't had issues with pimples back then, I am now paying my dues in my 30's. I was talking to Mom & some friends her age & they said that they have dealt with more skin problems since they are older, than they ever did as a youngster. I think I should do an acne treatment review, to see what are the best products for aging skin. I need some kind of spot treatment product. Now that would be nice.
