Azelaic acid is one of the most versatile multitaskers in modern skincare. Found naturally in grains like barley, wheat and rye, it helps with three of the most common skin concerns at once, visibly evening the look of dark spots, calming the appearance of redness and helping blemish-prone skin look clearer. Korean skincare formulations have made azelaic acid more wearable than ever, pairing it with gentle hydrators and soothing actives for a comfortable, lightweight feel.
