How Allantoin works 알란토인
Allantoin is a conditioning agent that helps soften keratin at the skin surface, so flaky, rough-feeling areas look smoother. It is widely used for its comforting effect on stressed-looking skin, and its very good tolerance profile is a large part of why it appears in so many soothing formulas.

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.
