Ingredient Deep Dive: Marimoist - What is it and why do I want it?

Meet the Hydrate Booster serum — a lightweight hydration hit built for skin that's still finding its balance.

At the center of it is Marimoist™, a moisture-boosting blend of hyaluronic acid and sea plant extracts. It draws moisture in and locks it there, supporting a healthy skin barrier so skin feels soft, fresh, and comfortable — morning, night, or whenever it needs a reset.

Here's what makes marine-based hydration different: sea plants grow in mineral-rich water and pick up things land plants never touch — trace minerals like magnesium and zinc, amino acids, and polysaccharides that act as humectants, binding water right at the skin's surface for a plumper, bouncier look. The result is hydration that feels lightweight and fast-absorbing instead of heavy, with mineral support for overall skin function layered on top.

Use it with the Pour Tous Serum for Glow to maximize the hydration - or use it on its own for that quick fix. Safe to use with other products, other boosters, and in any amount. 

Bottom line: a lightweight way to hydrate that won't feel greasy or heavy — good for skin still figuring out its own oil balance.
