The 10 star ingredients of K-Beauty
The strength of Korean skincare lies less in the number of steps than in the quality of its actives. Here are the ten that appear in every routine — and what they actually do.
The hydrators
Hyaluronic acid: holds up to a thousand times its weight in water; Korean formulas use several molecular weights to hydrate at several depths. Ceramides: rebuild the mortar of the skin barrier, essential for sensitised skin. Beta-glucan: even more hydrating than hyaluronic acid, soothing, derived from oats or mushrooms.
The correctors
Niacinamide: tightens pores, regulates sebum, fades dark spots — the most versatile active. Vitamin C: antioxidant, evens tone and boosts morning glow under SPF. Retinol: the anti-ageing reference, introduced gradually in the evening. AHA/BHA: gentle chemical exfoliants that smooth skin texture without mechanical scrubbing.
The Korean soothers
Centella asiatica: the emblematic healing plant, everywhere in "cica" ranges. Snail mucin: repairs, plumps and smooths — the ingredient that introduced the West to K-Beauty. Fermented ginseng: Korea's traditional antioxidant, energising for dull skin.
