Hyaluronic Acid
Sodium Hyaluronate · biotechnological origin, two molecular weights
Hyaluronic acid is the skin's own moisture molecule — a sugar that holds up to a thousand times its weight in water. SKEYNDOR's is grown by biotechnological fermentation, with no animal source, and formulated at two molecular weights at once: a high weight that stays on the surface, and a very low weight small enough to work in depth.
The work it performs
What it does
High molecular weight HA forms a breathable film that reinforces the barrier and slows water loss — immediate plumping and smoothing.
Very low molecular weight HA travels deeper, where it signals the skin to produce fresh hyaluronic acid of its own.
Together they hydrate on top of the skin and inside it at the same time — a water reserve with the surface sealed.
Visibly softens the fine lines that come from dehydration rather than structural ageing.
The range the professionals reach for on every skin type — including sensitive.

In the cabin
The Hyaluronic Dynamic professional program works the concentrate in with liposomed polarised water, selenite crystal stones and an aquaporin massage gel — six weekly treatments, extending to twelve for mature or severe dehydration.
The Power Hyaluronic treatmentHandle with care
This is the gentlest entry in the dictionary — the professionals report no contraindications, on any skin type. The only rule is dosage: five drops of the booster serum for lightly dehydrated skin, ten for mature or sun-damaged skin, fully absorbed before a cream goes over it. A booster does one job — always finish with a cream.
Pairs well with
- Xylitol & DerivativesHA holds the water; xylitol activates the aquaporin channels that move it evenly through the skin.
- Pure RetinolHydration first, renewal second — the professional sequence for dull, dehydrated skin.
- Marine Mineral-Thermal ComplexRemineralise and hydrate together — thermal water restores minerals and pH while HA manages the water balance.
