Description
Mandelic Acid is an alpha hydroxy acid (AHA) naturally derived from bitter almonds. Due to its larger molecular size compared to other AHAs, it penetrates the skin more slowly, making it less likely to cause irritation or redness. BiON’s Mandelic Serum 15% offers antibacterial benefits, helps regulate oil production to prevent acne breakouts, unclogs pores, gently exfoliates, and promotes healthy cell turnover. This serum is ideal for treating acne, reducing the appearance of fine lines and wrinkles, and improving skin tone by addressing pigmentation concerns. Plus, BiON’s Mandelic Acid Serum is ALCOHOL FREE!
