@leeskincare7: Closed comedones happenen when your pores get trapped by dead skin cells or gunk. So you need exfoliants or retinoids to push them out and speed up cell turnover rate. On other days I used azelaic acid for anti inflammatory effect and helps my skin tolerate retinoids better Also don't forget to keep your barrier protected with moisturizer! It's best if you can also figure out the culprit product and take it out of your routine. #closedcomedones #cloggedpores #texturedskin #koreanskincare
