PRODUCT DETAILS

Hello, hydration. This lightweight facial serum is made for dehydrated skin, bringing together a 14-layer ultra-low-molecular-weight hyaluronic acid concept and fresh seawater from Ulleung Island. The focus is clear: deep hydration for dehydrated skin.

The multiple declared forms of hyaluronic acid make hydration the heart of this serum, with fresh Ulleung Island seawater as its distinctive partner.

Hydration comes with a firming angle, too. The serum is intended to support a plumper-looking complexion, making it a thoughtful pick when a less firm look is part of what you want to address.

The texture keeps the experience easy: light, fresh and fast-absorbing without a heavy residue. It also suits oily, dehydrated complexions. The vegan formula adds one more practical reason to choose it.
