COSRX AHA 7 Whitehead Power Liquid
It's best to use as a serum in the evening due to its highly concentrated formulation. Begin using only once a week and once your skin has adjusted and doesn’t show signs of irritation you can increase to two to three times a week to decrease the visibility of pores and treat blemishes. Apply SPF if you're going outside the next morning.
***This product's high concentration of AHA (7%) may lead to a strong scent.
