Marine Collagen Serum

Korea ranking #34 serumUS stock

A lightweight gel serum built around marine-derived collagen, aimed at skin that wants a hit of hydration and a smoother, plumper-looking surface. It sinks in without a sticky film and layers easily under moisturizer. A sensible everyday pick for normal-to-dry skin, or anyone after a simple hydrating step.

More detail

Hydrolyzed collagen sits at the center: broken-down collagen that works as a humectant, drawing water to the surface for a temporarily smoother, more cushioned look (topically it hydrates rather than rebuilding your own collagen). It's joined by adenosine, a functional ingredient with data for supporting firmness, plus arginine and glycerin-type humectants that help hold onto moisture. The texture is a clear, light gel that spreads thin and absorbs quickly with a soft finish. Smooth a few drops over cleansed skin after toner, morning and night, then seal with moisturizer. The formula is fragrance-free and low-fuss; note that marine collagen is fish-derived, so it isn't vegan.
