COSRX AHA 7 Power Liquid (HC Version) 100ml

The cosrx aha 7 whitehead power liquid is one of the shortest ingredient lists in the category: ten items, and the first one is apple fruit water rather than plain water. Glycolic acid sits third at 7%, which puts it firmly in leave-on exfoliant territory rather than in the gentle-toner category.

Glycolic acid is the smallest of the alpha hydroxy acids, which is why it works on surface texture and the look of congested, bumpy skin. Used two or three times a week, the cosrx aha whitehead power liquid smooths how skin feels and looks rather than delivering an overnight change.

The supporting cast matters. Niacinamide at 2% and panthenol and sodium hyaluronate are there to keep the formula from being purely stripping, which is the usual complaint about acid toners. There is no fragrance and no alcohol. Cosrx canada shoppers usually treat this as the step to introduce slowly and build up, not something to start using nightly.
