Hyaluronic Acid

Sodium Hyaluronate · biotechnological origin, two molecular weights

  • Hydration
  • Plumping
  • Barrier

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

Surface reserve

High molecular weight HA forms a breathable film that reinforces the barrier and slows water loss — immediate plumping and smoothing.

Working in depth

Very low molecular weight HA travels deeper, where it signals the skin to produce fresh hyaluronic acid of its own.

Two weights, one system

Together they hydrate on top of the skin and inside it at the same time — a water reserve with the surface sealed.

Softened lines

Visibly softens the fine lines that come from dehydration rather than structural ageing.

The Power Hyaluronic treatment

Handle 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.
