Our Mandelic Scrub Cleanser is forumlated to help reduce hyperpigmentation, penetrating deep into the skin to loosen the bonds that hold your skin cells together. Mandelic acid is among the family of exfoliants known as alpha hydroxy acids or AHAs. They include mandelic, glycolic and lactic acids. Not only do AHAs unclog pores to clear acne, but they also smooth fine lines, improve rough texture and assist in shedding hyper-pigmented skin cells, which reduces post-inflammatory hyper-pigmentation (dark spots from old acne). AHAs also help benzoyl peroxide work much more efficiently because they get rid of old, dead skin cells that may be blocking your follicles.
