*** A CONSULTATION IS REQUIRED IN ORDER TO PURCHASE THIS PRODUCT 8% Mandelic Serum is an alpha hydroxy acid serum that contains the chirally correct versions of both L-Mandelic Acid and L-Lactic Acid. These key ingredients offer exfoliating properties and can help diminish the appearance of discoloration. Niacinamide offers antioxidant support for the skin. This water-based serum is appropriate for all skin types and for skin that needs a boost up from 5% Mandelic Serum. Safe for use on skin prone to all types of acne and can be used on skin that is not prone to acne. Mandelic acid has a larger molecular weight than other alpha hydroxy acids, slowing down epidermal penetration resulting in a more even exfoliation with less irritation. Recommended for skin that needs a boost up from 5% Mandelic Serum. Apply 2 to 3 pumps all over a clean face or affected area.
