Our gold standard 8% L-Mandelic Serum is an alpha hydroxy acid serum that contains the chirally correct versions of both l-mandelic acid and l-lactic acid. L-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. This water-based serum is recommended for skin prone to inflamed acne, noninflamed acne, fungal folliculitis, and hyperpigmentation. Recommended for skin prone to all types of acne, folliculitis, and hyperpigmentation. 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.
