How Cholesterol works 콜레스테롤
Cholesterol is one of the three lipid families — with ceramides and free fatty acids — that form the mortar between surface skin cells. Research on barrier repair points to the ratio between the three mattering more than the amount of any single one, which is why well-built barrier creams supply all three together.

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.
