For an acid exfoliant, it’s one of the gentler ones. It’s quite easy to gradually get used to daily use. Just go easy and compensate for its dryness by adjusting the rest of your skincare routine.

Cosrx seems to have reformulate it, because my old bottle smelled like a dead fish in a rubber boot, but this new bottle doesn’t stink as much. Stink or no stink, I’d still be willing to endure it because it gives great results in smoothing skin texture, fading dark spots and reducing closed comedones.
