Skin irritation test completed. As soon as we saw the ingredients list, we knew we had to have Some By Mi's AHA 10% Amino Peeling Ampoule. What makes this exfoliating serum a standout is that it uses a 10% concentration of mandelic acid to gently remove dead skin and even out skin tone. Mandelic acid is a larger molecular weight AHA, meaning that it is slower to penetrate the skin than traditional AHAs like glycolic acid. This makes it ideal for sensitive skin, darker skin tones and anyone looking for a gentler alternative. It also includes BHA (salicylic acid), PHA (gluconolactone) and LHA to help fight acne and clogged pores. Meanwhile, amino acids, cica and ceramides combat potential irritation. Avoid mixing it with other actives (like vitamin C, retinol and niacinamide), and always apply SPF during the day. For the best results, apply a hydrating serum or facial oil afterwards to protect the skin's barrier.
