The heart of Hyalustar

Can an entire brand revolve around a single ingredient?

For Hyalustar, the answer is yes. Here's why.

Hyalustar face serum

Imagine a meadow in bloom: lush green plants and soft but firm soil. While the weather is calm, everything looks perfect, almost like a fairy tale. But in nature, true strength is revealed when things change.

Well-hydrated, stable soil stays healthy over time: even in a storm, plants with strong roots sway but do not fall. When soil is rich in water, it does more than withstand change: it absorbs nourishment deeply. Water and nutrients do not simply run off the surface; they are retained and distributed where they are needed. If soil is dry or fragile, it takes little to disrupt it, and even the things that could nourish it are lost.

Now imagine that our skin is that soil.

Like the earth, skin needs care and hydration to stay healthy and resilient. This helps it adapt to change, defend itself against external factors and absorb the nourishment we give it.

Like a little garden: water, nourish and protect it every day.

In practice: when skin is intelligently hydrated, everything works better, even as its environment changes.

The heart of Hyalustar

PrincipHYAL® Cube³

(pronounced prin-si-pial cube!)

PrincipHYAL® Cube³ is our special ingredient.

It is a biomimetic hyaluronic acid, very similar to the one skin naturally produces.

How is it made?

Through a controlled process starting with plant-derived ingredients. In a protected, monitored environment, different forms of hyaluronic acid are created and linked harmoniously, like a city skyline, just as they are in skin.

The result is a soft, pure white powder, ready to be incorporated into our formulas.

Every Hyalustar product contains a pure, powerful ingredient that works in synergy with skin.

Hyalustar chose PrincipHYAL® Cube³ as the foundation for all its formulas because it is exceptionally compatible with skin (biomimetic).

Biomimicry also means biomodulation! What does that mean? Skin receives natural, continuous stimulation from PrincipHYAL® Cube³, just as it normally works. This supports natural, continuous and even more effective activity!

PrincipHYAL® Cube³ becomes the ally your skin deserves.

Skin's balance

Why PrincipHYAL® Cube³ is different

In harmony with
your skin

Different forms of hyaluronic acid.
A balance skin recognises.

01More than one molecular weight

Hyaluronic acid can have longer or shorter chains, with different properties. Molecular weights describe these differences.

02Just as it happens in skin

Skin contains different forms of hyaluronic acid that work together. Their balance is part of its natural complexity.

03The biomimetic choice

PrincipHYAL® Cube³ reflects this organisation. This is what biomimeticmeans: respecting a balance that skin recognises as familiar.
