T.L.C. Framboos Glycolic Night Serum

A 12% blend of glycolic, tartaric, lactic, and citric acids with a touch of salicylic, buffered by raspberry extract in a gel that resurfaces overnight. It was the AHA that taught a generation to 'smoothie' their actives, and morning-after glow remains its best argument. Strong enough that beginners should not start here.

Around $90
