Collistar Pure Actives Hyaluronic Acid + Polyglutamic Acid is a concentrated serum that includes 4 different molecular weights of hyaluronic acid and polyglutamic acid for intense, multi-layered hydration.

The hyaluronic acid used in the formula is a special combination of 4 different molecular weights:

• High: forms a protective film on the skin's surface, reducing natural water loss.
• High-medium: traps water on the skin's surface, nourishing the stratum corneum.
• Medium-low: provides hydration and repairs damage to the stratum corneum.
• Low: penetrates deep into the skin, hydrating and repairing it from within.

The hyaluronic acid is combined with polyglutamic acid: this biocompatible combination enhances hydration thanks to its excellent water retention capacity, while also preventing the degradation of hyaluronic acid naturally present in the skin.

The formula is also enriched with inulin, a natural prebiotic that helps maintain the skin's microbiome by selectively nourishing its bacterial flora and aiding in the proper functioning of the epidermal barrier.

Results: The skin is deeply hydrated, fine lines and signs of dehydration are gradually minimized, and the skin's surface becomes smoother and more radiant.

Suitable for all skin types, including sensitive skin. Recommended after non-invasive aesthetic treatments.
