Hyaluronic Acid Serums

Light as water, heavy on hydration. Our hyaluronic acid serum uses 2% pure hyaluronic acid at 3 different molecular weights, so hydration reaches multiple layers of your skin rather than sitting on the surface. Matrixyl 3000 helps skin look plumper and smoother over time. Choose your size below, or pick up a duo if hyaluronic acid is already a permanent step in your routine.


Why hyaluronic acid? Dehydrated skin can look dull, feel tight and show texture more than it needs to. Hyaluronic acid is a humectant, which simply means it draws water into the skin and holds it there. The molecular weight matters. Smaller molecules travel further into the upper layers, larger ones hydrate closer to the surface. Using three weights together means you're not relying on one to do everything. One tip that makes a real difference: apply to damp skin, then follow with a moisturizer to seal it in.


Choosing your size:

30ml - the standard size. Best if you're new to hyaluronic acid or want to try it before committing.

60ml - twice the size, better value per ml. Best if hyaluronic acid is already a regular step for you.

100ml Supersize - our largest size and best value per ml. Best if you use it morning and night, or across face and neck.

Duos - two bottles, one order. Best if you're sharing, or want a backup before you run out.
