How Mayu (Horse Oil) works 마유
Rendered horse fat has a fatty acid profile — relatively high in oleic and palmitoleic acids — that is closer to human sebum than most plant oils, which is the usual explanation for how readily it absorbs and how well it sits on chapped skin. Functionally it works as an occlusive-emollient: it slows evaporation and softens the surface. The compositional similarity is documented; the regeneration claims built on top of it are not.

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.
