How Witch Hazel (Hamamelis) works 위치하젤
Witch hazel is rich in tannins, which bind to proteins at the skin surface and cause a brief contraction — the tight, freshly-scrubbed sensation people read as pore-tightening. That effect fades within the hour. Many commercial distillates also contain alcohol from the extraction process, and on skin that is already reactive the combination of tannin astringency and alcohol is a plausible route to the redness the product was bought to fix.

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.
