Hydration is no longer enough. Skin demands duration.
Capturing water is simple. Holding it is a matter of molecular architecture. The GleySy® multi-fraction hyaluronic acid synergy, fraction by fraction.
Skin never lacks water. It lacks what holds it.
Hydration is the first step of professional care, and the one most often reduced to its simplest expression: supplying water. Yet skin is not judged in the moment that follows a treatment. It is judged three days later.
Everything in between comes down to structure. Capturing water is easy. Holding it, organising it, releasing it over hours calls for a molecular architecture built for the task.
That architecture is what GleySy® has worked on from the start, under one name: multi-fraction hyaluronic acid synergy.
One molecule, many chain lengths
Hyaluronic acid is not a molecule: it is a family. A single INCI name covers chains of very different lengths, measured in daltons, from a fragment of a few hundred daltons to a polymer of several million.
That length is no manufacturing detail. It governs how the chain behaves: its mobility, the level at which it sits, the volume of water it structures and how long it does so.
- Low-molecular-weight fractions are mobile and diffusing.
- High-molecular-weight fractions structure water at the surface and deliver immediate comfort.
- Cross-linked structures resist natural enzymatic degradation for longer.
A formulation built on a single chain length therefore plays in one register only. It hydrates — in the singular.
Multi-fraction hyaluronic acid synergy
The GleySy® approach brings together, within one formula, several hyaluronic acid fractions chosen for how they complement one another — not for how many they are.
Each fraction occupies its own level. Their assembly does not aim at a peak of hydration: it aims at continuity. The most mobile fractions open the way, the longest hold the duration.
One fraction gives a moment. Several coordinated fractions give a duration.
The detail of that assembly belongs to the laboratory. What is visible is the logic governing it: every molecular weight must have a reason to be there, and only one.
HYAL PURE — hyaluronic acid, and nothing else
With HYAL PURE, GleySy® demonstrates multi-fraction synergy in its most pared-back state: hyaluronic acid, with no supporting active lending its name to the result.
Two concentrations answer two protocol intentions: Hyal Pure 1% for sustained work on skin quality, Hyal Pure 2% when the practitioner is seeking reinforced hydration. The level is chosen by protocol, not by default.
Its signature: mastery of a formula with nothing to hide behind a star ingredient.

RICH PDRN combines Sodium DNA — PDRN nucleotides — with amino acids, L-lactic acid and hyaluronic acid. Hydration is not an isolated objective here: it is the medium in which the other actives work.
That is the difference between watering and preparing ground. A properly hydrated dermis is one where what comes next finds its place.
PDRN and peptides now have an article of their own: the new intelligence of professional skincare.
Its signature: hydration used as a foundation, not as a promise.

RICH BTX brings together neuropeptides and hyaluronic acid. Expression areas — forehead, eye contour, folds — are where water loss shows fastest, because they move.
Pairing hyaluronic acid with peptides there is a matter of formulation coherence: supple skin holds over time better than dry skin, however precise the rest of the formula.
A cosmetic peptide formulation: its action is not comparable to that of a botulinum toxin injection and makes no claim to replace it.
Its signature: smoothness and hydration designed into the same formula, not one after the other.

Beyond free chains, cross-linking — chains bound to one another in a network — changes the nature of the problem. A network degrades more slowly than an isolated chain: duration stops being a consequence and becomes a formulation parameter.
GleySy® puts that principle to work in LiftDerm, where a Sodium Hyaluronate Crosspolymer completes the free fractions. The two registers do not replace one another: they take over from one another.
Hydrating is not a step, it is a line
In-practice care establishes the supply. Daily care holds it. Between the two, continuity of formulation makes the difference between a result visible that evening and a result that settles.
The same requirement governs the professional peel range: the science of peeling — another range, a single formulation method.
GleySy® hydration is not measured at the moment of the treatment. It is measured by what remains of it.
