Hydrators, explained

There is a critical difference between hydration and moisture. Hydration is water content — how plump and supple skin feels. Moisture is the ability to retain that water — the integrity of your barrier. You need both. These ingredients work at different levels of the skin to deliver and lock in hydration.

Hyaluronic Acidgentle

Draws water into skin for instant plumping.

Holds up to 1,000 times its weight in water. Draws moisture from the environment and deeper skin layers to the surface. Available in multiple molecular weights — high-weight for surface plumping, low-weight for deep penetration.
