1
The middle rung of the retinoid ladder. Because it needs fewer conversion steps than retinol, it is generally considered more potent at the same percentage — start low, go slow, and always pair it with sunscreen the next morning. Retinoids are also the one category conventionally avoided altogether in pregnancy and breastfeeding: here, 'caution' means skip it until after.
2
Close cousin of galactomyces and the reason first essences exist at all. Yeast ferment filtrates are conditioning ingredients — read the marketing about 'cell renewal' as appearance language, not a proven biological claim.
3
You have read this name a hundred times on Korean sunscreen and cushion labels without registering it. It is a synthetic ester chosen for one quality: a dry, fast-spreading slip that stops filter-heavy formulas feeling like grease. Purely a texture ingredient, and an unusually good one.
4
Here is the honest version: collagen molecules are far too large to travel into skin and become your collagen. Topically it is a very good moisture-holding film — the firmness marketing is doing more work than the ingredient.
5
The volatile silicone behind the dry, powdery glide of Korean primers, cushion foundations and sun sticks. It carries other ingredients across skin and then leaves. Because it evaporates rather than sits, it does not occlude the way dimethicone does — which makes the pore-clogging accusation aimed at it particularly poorly targeted.
6
Silicones took an undeserved reputational beating. Dimethicone does not suffocate skin — it is a well-tolerated film former, and it is most of the reason a Korean sunscreen applies so smoothly.
7
Fermented sweet tea, filtered and put in an essence. It brings green tea polyphenols plus the acids and sugars fermentation produces, which is a plausible mix for surface conditioning. The evidence for kombucha specifically, as opposed to green tea or ferments in general, is slim. A pleasant ingredient with a good story attached.
8
The AHA for people whose skin gets tight after exfoliating. Lactic acid holds water as well as loosening dead surface cells, so it tends to leave skin less parched than its sharper relatives.
