@skin.ken: Azelaic acids that actually work!! These are some that I’ve tested and I find them to be very effective despite being at different concentrations. The formulation really matters with azelaic acid so be sure to choose one that your skin will tolerate!#azelaicacid #anua #koreanskincare #azelaicacidserum #torriden
