It's jam packed with gentle but high-performing acids to exfoliate, reduce the appearance of blemishes, discoloration & acne scars, as well as Niacinamide to control excess oil production, and also CoQ10 to reinforce skin's natural barrier function. It's targeted for those suffering from hormonal imbalance, and co-created by OB-GYN @therealdrjackie
