Exfoliation removes dead surface cells so skin looks smoother and more even — but it’s easy to overdo, and over-exfoliating is a common cause of irritation and a damaged barrier. Korean routines lean heavily on gentle chemical exfoliation rather than harsh scrubs: AHAs are water-soluble and work on the surface, BHA (salicylic acid) is oil-soluble and works inside pores, and PHAs (like gluconolactone) are the largest, gentlest molecules, often chosen for sensitive skin. Below are the main exfoliator types, with honest notes. Start a couple of times a week at most, wear sunscreen, and patch test — and stop if you see redness or stinging.
