2 ingredients that made the biggest difference in my skin are these. Adapalene helps keep pores clear by speeding up cell turnover, and work on clogged pores better. Azelaic acid helps calm the redness and fade post acne marks, gently exfoliates. Healthy skin barrier, hydration, sunscreen, and consistency matters too! #koreanskincare #cloggedpores #closedcomedones #retinol
