Why PHA & LHA? PHA and LHA are the gentlest exfoliating acids available — larger molecules that work on the skin's surface rather than penetrating deep, which means you get smoother texture and clearer pores without the redness or peeling that comes with glycolic or salicylic acid.
This is Lindsey's pick for clients who've tried exfoliating acids before and reacted badly — gentle enough that even her most sensitive clients can finally add exfoliation back into their routine.
