DESCRIPTION
Azelaic acid is one of the few actives that suits both blemish-prone skin and skin that reddens easily, which is why it has moved from prescription-only into the K-beauty mainstream. Anua use it at 10%, buffered with hyaluronic acid and panthenol so it is far less drying than the strength suggests. Betaine salicylate sits alongside it to help keep pores clear. It is a lightweight serum that goes between toner and moisturiser, and the sensible way to start is once or twice a week, building up. Because it is an acid, daily sunscreen is not optional while you use it. A 30ml dropper bottle.
