The famous 10-step Korean routine is less a rulebook and more a menu. Start with the essentials — cleanse, hydrate, moisturize, and protect — then add serums and masks as your skin asks for them.
The core 4
Cleanse — a gentle low-pH cleanser morning and night.
Hydrate — a watery toner or essence to prep the skin.
Moisturize — lock it in with a lightweight lotion or cream.
Protect — SPF every single morning, no exceptions.
