Hyaluronic Sea Serum

The Hyaluronic Sea Serum is OSEA's hero face product featuring three molecular weights of hyaluronic acid that work together to hydrate skin at different levels.

Combined with Japanese Miru seaweed, volcanic marine ferment, and snow mushroom, this serum provides instant hydration while smoothing the appearance of wrinkles and plumping skin.

The texture is lightweight and slightly watery—comparable to aloe vera—making it easy to spread and quick to absorb.

Reviews

"This Hyaluronic Sea Serum is my favorite that I have tried of any brand. My skin looks and feels so good when I use it. I use this every day in the mornings and use the Dream Night Serum in the PM. I actually prefer this one between the two, but will continue to use both."
