1
The ultimate multitasker — 2–5% suits most skin. The old “don’t mix with vitamin C” rule is a debunked myth.
2
Salicylic acid dives into oily pores to decongest. Ideal for blackheads & breakouts.
3
Houttuynia cordata — a trending calming extract for oily, breakout-prone skin.
4
Charcoal binds things to its surface, which is why it works in water filters and why it looks convincing in a black clay mask. On skin it picks up surface oil during the couple of minutes it is there. The detox framing is nonsense — nothing is being drawn out of a pore, and a peel-off charcoal mask mostly removes your vellus hair.
5
The single most argued-about line on a Korean sunscreen label. Denatured alcohol is why that sunscreen feels like nothing and vanishes under makeup — it flashes off and leaves the filters behind. It genuinely stings compromised or sensitised skin. The claim that it damages a healthy barrier at cosmetic levels is far shakier than the internet suggests.
6
Like birch sap, bamboo water is used as a lighter-feeling base. It shows up most in gel textures aimed at Korea's humid summers, where anything richer feels unbearable.
7
고삼 (gosam) is the bitter root that Korean brands reach for in scalp tonics and blemish toners. Laboratory work on its alkaloids is interesting; controlled evidence on human skin is close to absent. Acne that is not shifting is a dermatologist's problem, not a botanical toner's — see one rather than waiting on a root extract.
8
Camellia sinensis from Jeju — antioxidant-rich and beloved for oily, sensitive skin.
