Hydration Serum — 4 Weight Hyaluronic Acid
Layer hydration from the surface inward with four-weight Hyaluronic Acid.
Four weights of hyaluronic acid, one quiet result: my skin stays comfortable all day instead of tight by noon.

Every active is here because the research supports it. Concentrations and study links below.

Is this for you?
This is ideal if you:
- Have any skin type and want a universal hydrator
- Need hydration without active sensitizers
- Are post-procedure or have compromised barrier
- Layer multiple actives and need a neutral base
Not ideal if you:
- Want active treatment in this step
- Need occlusive or rich emollient
- Apply HA to dry skin without sealing
Why this formula works
High molecular weight surface
1,000+ kDa HA forms a hydrating film at the stratum corneum — immediate, visible plumping.
Low and ultra-low penetration
Below 50 kDa, HA reaches the living epidermis — the deepest layer this serum's hydration is designed to reach.
Active-free formulation
No retinol, no acids, no sensitizers. Designed for compatibility with everything else in your routine.
How to use
AM and PM
Apply to slightly damp skin and follow with moisturizer to seal. HA binds to water — there must be water present for it to bind.
