What is it?

Polilisina is an innovative prebiotic that selectively acts on the bacteria responsible for acne, such as the Cutibacterium Acnes. It supports rebalancing the skin microbiome, improving skin health and reducing the appearance of blemishes.

What is it for?

Polilisina is a specific prebiotic that helps counteract the proliferation of acne-related bacterial strains without altering the balance of the skin microbiome. Its targeted action makes it possible to:
- Weaken C. acnes strains, reducing the formation of pimples and blackheads.
- Promote "good" bacteria, supporting a healthy, balanced microbiome.
- Regulate sebum production, improving skin balance.
- Soothe inflammation and reduce redness and irritation associated with acne.

Thanks to its selective action, Polilisina is ideal for blemish-prone, oily, or acne-prone skin.

Polilisine is an advanced prebiotic with a unique mechanism of action: it selectively weakens acne-associated strains of Cutibacterium acnes (C. acnes), one of the primary causes of pimple and blackhead formation. Unlike other purifying ingredients, it acts in a targeted manner, preserving the beneficial bacteria that make up the skin microbiome.

How does it work?
An imbalanced microbiome, often caused by stress, excess sebum or external factors, can lead to overgrowth of C. acnes. Polilisine selectively targets these bacterial strains, reducing their activity and preventing the formation of impurities. At the same time, it promotes good bacteria, helping to restore balance to the skin.

Who is it suitable for?
Polilisine is particularly effective for:
- Oily and acne-prone skin that needs targeted action against impurities.
