Hyper ACID4 30 Serum

Four families of exfoliating acid, AHA, BHA, PHA and LHA, account for thirty percent of this formula. Two or three drops are worked over the face for roughly a minute, away from eyes and lips, then rinsed off with lukewarm water instead of being left on. Gluconolactone, lactic acid, glycolic acid and salicylic acid loosen dulling build-up and the sebum sitting inside pores; the brand places the step in the evening.
