How Collagen (topical) works 콜라겐
Intact collagen is far too large to pass into skin, and while hydrolysed fragments are small enough that some may cross the surface, nothing applied topically is taken up and built into skin's own collagen network. What they do reliably is sit at the surface as a water-binding film, which makes skin look and feel immediately smoother and more cushioned.

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.
