Why serums, not creams
Why serums, not creams.
A cream's main job is to seal moisture in. A serum's job is to deliver an active ingredient. That's why we only make serums.
Concentrated — a lightweight base built around the active, not around texture.
Targeted — one formula, one concern. No 10-in-1 promises.
Layerable — goes under your moisturizer and SPF, not instead of them.
Hydration / Daily Essential
Moisture, Precisely Replenished.
A lightweight hydration serum built around sodium hyaluronate and glycerin, formulated to replenish moisture and leave skin feeling plump, smooth, and refreshed. Fast-absorbing and easy to layer, it's the foundation step for hydrated, balanced-looking skin.
- Sodium Hyaluronate
- A moisture-binding humectant that helps skin attract and hold water at the surface.
- Glycerin
- A well-studied humectant that supports the skin's moisture levels.
- Butylene Glycol
- A lightweight conditioning ingredient that helps the formula spread evenly and absorb quickly.
