Hydraboost HA Serum

Sodium hyaluronate and panthenol in a light water-based serum. The first step in a routine, on damp skin.

Sodium hyaluronate is the salt form of hyaluronic acid; panthenol is provitamin B5. Both are humectants — they hold water where they are applied. Neither is an active in the sense the rest of the range is. Nothing in this bottle asks skin to change.

Because humectants draw water, put it on damp skin and follow it with a moisturiser. In dry air, on dry skin, left uncovered, a humectant has less to work with.

First step, morning or night, as often as you want it. If it stings, stop — a formula this plain stinging usually says something about the skin rather than the bottle.

Actives: Hyaluronic Acid, Panthenol (Vitamin B5)

Suits: Any skin state. Layers under everything else.

Not for: Not a moisturiser — it holds water, it does not seal it in.
