Improve skin hydration

What this outcome means

Skin hydration is how much moisture your skin holds, shaping whether it feels supple and smooth or tight and flaky. On DoseRank it maps to a defined health outcome built from human studies on corneometry moisture readings, transepidermal water loss, and skin elasticity – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Chronically dry skinTight, flaky patches that no amount of cream seems to settle.

Harsh-climate exposureCold wind, dry heat, or indoor air that pulls moisture away.

Maturing skinSkin that holds less water and feels rougher with age.

Stack buildersAlready taking supplements such as Sodium Hyaluronate and want the dose right.
