What is "ALPHA-GLUCAN OLIGOSACCHARIDE" and what does it do?

Role: HUMECTANT

Family: PREBIOTICS

Comedogenic index: 0

Alpha glucan oligosaccharide is a natural prebiotic, typically synthesized from sugars, which supports a healthy skin microbiome.

Role and functions
Skin Microbiome Support
This prebiotic helps maintain the balance of the skin microbiome, essential for controlling the proliferation of harmful bacteria and preventing skin irritation and sensitization.

Antioxidant properties
Alpha and beta-glucan oligosaccharides also offer antioxidant benefits, helping to reduce the visible effects of oxidative stress on the skin.

Use in Cosmetics
Recommended concentrations
The recommended use of alpha-glucan oligosaccharide in skin care ranges from 0.25 to 3% alone, and from 0.5 to 3% when combined with other prebiotics.

Synthesis and Protection
Obtainability and selectivity
This skin-protecting ingredient is obtained by enzymatic synthesis from natural sugars (sucrose and maltose). It is recognized as a bio-selective substrate that protects and stimulates the skin's beneficial microbial flora, without favoring pathogens and undesirable flora.

Stimulation of Antimicrobial Peptides
It also stimulates the release of antimicrobial peptides by keratinocytes, boosting the skin's natural defenses.
