HA Densimatrix

Sale price$175.00

A hyaluronic acid serum combining four molecular forms with calcium ketogluconate, formulated fragrance-free for dehydrated skin of any type.

When to use Morning and evening, on damp skin before moisturiser
How it works

Four sizes of the same molecule

Hyaluronic acid’s effect depends on its size. Full-weight sodium hyaluronate lies on the surface as a breathable, water-holding film. The hydrolysed fragment is small enough to settle into the upper layers and hydrate from within them. The acetylated form carries a lipid modification that anchors it to skin, so it survives washing and lasts longer. And the crosspolymer is a mesh of linked chains, a reservoir that swells with water and releases it back slowly across the day.

Defending your own reserves

Skin constantly breaks down its own hyaluronic acid via the enzyme hyaluronidase. Calcium ketogluconate, the quiet co-star of the Densimatrix line, is included to moderate that breakdown, so the serum protects the hyaluronic acid you make as well as adding its own.

The supporting pair

Malachite extract, a copper-mineral antioxidant, and marshmallow root, a mucilage-rich soother, in a sixteen-ingredient, fragrance-free formula with nothing speculative riding along.

What plumpness means here

Water, held well, visibly plumps fine lines and gives skin its bounce back. It is a hydration effect, genuine and renewable daily, not a structural change.

Who it suits

Dehydrated skin at any age, fine lines that soften when skin is well watered, and any routine missing its hydration layer, including sensitive and reactive skin, thanks to the short fragrance-free formula. It is also a comfortable companion in the weeks around in-clinic treatments; follow your practitioner’s timing.

Worth knowing

Nothing in the formula carries a common allergen flag, one of the cleanest ingredient lists on our shelf. Drink-your-water disclaimer: a hyaluronic serum holds water in skin; it works best with a moisturiser over it to seal the deal.

How to use

Morning and/or evening on lightly damp skin: a few drops over face and neck, then follow with moisturiser while skin is still tacky, humectants do their best work with water to grab and a seal to keep it.

Layers under anything, including actives.

Layering

Use alongside

The universal middle layer: under Humidify, Harmonize or Couperend at night, under moisturiser and SPF by day. It plays the same hydration-serum role as Surge, choose by feel and brand loyalty rather than doubling up. Pairs happily with actives (retinoids, vitamin C, pigment leaders) as the comfort layer that makes them easier to wear, and with HA Densimatrix Lips as the matching lip step.
