This multi Acid serum is level #1 in a two level serum for all non-sensitive skin types. This serum is designed to exfoliate your skin while naturally increasing your skin's moisturization. Glycolic and Hyaluronic Acid creates a softer, smoother skin texture and tone, clears up oily/acne prone skin, clears up blackheads, reduces acne scarring and the appearance of dark pores, all without drying out your skin! This serum is the beginning level. Use this for a few months before moving up to the 30% Serum ( level #2).
