How Phenoxyethanol works 페녹시에탄올
Phenoxyethanol disrupts bacterial cell membranes and interferes with the processes microbes need to multiply, which keeps a water-containing formula stable through months of dipping fingers and bathroom humidity. It works across a wide pH range, which is why it suits everything from a low-pH acid toner to a neutral cream. Its safety at the capped level has been reviewed repeatedly by regulators in Korea, the EU and elsewhere, which is why the same 1% ceiling appears across markets that rarely agree on anything.

🙋 People also ask
How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
Does Korean skincare work for deeper skin tones?
The skincare does — hydration, barrier support and soothing actives are not tone-specific. The friction points are mineral sunscreens that leave a cast and a colour-cosmetics shade range that has historically been narrow.
