@dr.farzan: Closed comedones are clogged pores that appear as small bumps. To improve them, use non-comedogenic products and gentle exfoliation. Salicylic acid helps clear inside the pores, while glycolic acid smooths the skin surface and helps prevent buildup. Use @Arencia Eraser shot daily to improve/prevent closed comedones! #closedcomedones #whitehead #cloggedpores #Arencia #blackhead
