Adapalene

Also listed as Differin

What it does

A third-generation retinoid made for acne. It unclogs pores and calms inflammation with less irritation than tretinoin, and at 0.1 percent it is sold without a prescription in many countries.

How to use it

Evenings, a pea-sized amount spread over the whole area rather than dabbed on spots. Give it around 12 weeks to show results, wear SPF daily, and avoid it during pregnancy.

In our catalog

None of the products in our catalog contain Adapalene; it is mostly sold as a prescription or pharmacy treatment rather than as a cosmetic. Its pairings still apply if you use it alongside your K-beauty routine.
