Hydration/Dryness
For: dehydrated skin (lacks water — anyone can have it) or dry skin (lacks oil — a skin type). Both feel tight, look dull and need help holding moisture.
The Korean approach is layered hydration — multiple light layers absorb better than one heavy cream:
- Step 1 — humectant toners and essences.
- Step 2 — hydrating serums and ampoules.
- Step 3 — ceramide creams lock everything in.
