Strong acid peels (glycolic and friends)
Glycolic acid dissolves the glue between dead skin cells. At peel strengths it also makes skin measurably more fragile in the sun. In a controlled study, skin treated with glycolic acid showed more redness and more UV damage afterward. Teen skin already renews itself quickly; peeling it on purpose mostly buys you irritation and sunburn risk. A gentle cleanser does the job without the drama.
