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:

1. high: forms a protective film on the surface of the skin, reducing natural water loss.

2. high-medium: traps water on the surface of the skin, nourishing the stratum corneum.

3. medium-low: provides hydration and repairs damage to the stratum corneum.

4. low: penetrates deep into the skin, hydrating and repairing it from within.

Hyaluronic acid is combined with polyglutamic acid: this biocompatible combination enhances hydration thanks to its excellent water-holding capacity, while preventing the deterioration of the hyaluronic acid naturally found in the skin. The formula is also enriched with inulin, a natural prebiotic that helps maintain the skin's microbiome, selectively nourishing its bacterial flora and helping the epidermal barrier function properly.

Results: The skin is deeply hydrated, fine wrinkles and signs of dehydration are gradually minimized and the surface of the skin becomes smoother and brighter.

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