What is this product?

LAYER LAB Niozom Panthenol 5% Serum tells you its doses, which most serums do not: 5 percent panthenol and 4 percent niacinamide, over a small but real ceramide NP, cholesterol and phytosphingosine set and a full centella complex, and it is registered in Korea as a functional cosmetic for brightening and wrinkle improvement, consistent with the niacinamide and adenosine on its label. What it does not back up is its own headline: LAYER LAB publishes no test behind its 6.9-times barrier improvement figure, and no pH either. Reviewers mostly report moisture and relief from inner dryness, which matches who it suits: dehydrated, barrier-worn skin wanting a mid-routine hydration step, while very dry skin needs a heavier seal over it and plant-extract-sensitive skin should approach carefully.

What makes it different?

A serum that prints its own numbers, 5 percent panthenol and 4 percent niacinamide, on top of a genuine if modest ceramide and centella base. It comes in one 50ml size, sold only in Korea, with no English-language material from the brand.
