The most concentrated formula in the range. A daily serum that hydrates, evens the complexion and supports skin longevity, with 97% ingredients of natural origin.

Description

The most concentrated step of the ritual. Applied to clean skin, it carries the actives the cream will then seal in.

Why it works:

Trihelixsea™: our marine biotechnology complex. It smooths fine lines, restores firmness and elasticity, and reactivates cellular vitality.

Ydrixcell™: our Portuguese complex, born of Codium tomentosum farmed in certified organic aquaculture in Aveiro and of olive leaf extract from Vila Flor. It nourishes, reinforces the skin barrier and protects against oxidative stress.

Chlorella vulgaris: a regenerating microalga rich in proteins and antioxidants, selected by NASA for the photobioreactors of the International Space Station. It supports collagen synthesis and restores density.

Peptides: firmer skin, more defined facial contours.

Niacinamide and PHA: even tone, refined texture and radiance, with everyday tolerance.

Result:

Day after day, skin looks better protected, hydrated, luminous, firmer and visibly more even.

Free from parabens. Free from silicones. Vegan.

Suitable for all skin types.

Who Is It For?

For skin that has lost radiance and firmness, and for anyone looking for a high-performance, multi-benefit treatment. The serum delivers concentrated actives; the cream completes the ritual with lasting comfort and protection.

Suitable for all skin types.
