With a pH of 4.0 to 5.0, it targets uneven texture and dullness without stripping the surface, even after exposure to road dust.

Frequently Asked Questions
Can I use Cosrx AHA 7 every day?
Start with once or twice a week to avoid irritation. Daily use often causes over-exfoliation and damages the skin barrier.
Does Cosrx AHA 7 cause purging?
Active 7% Glycolic Acid can push underlying clogs to the surface. This temporary breakout phase typically lasts two to four weeks.
