Science
Mechanism of Action
This extract functions as a potent antioxidant, rich in B vitamins, vitamins A and E, and tocopherol, which collectively protect the skin from environmental stressors. It exerts soothing and anti-inflammatory effects, contributing to reduced irritation and a calmer complexion. Its capacity for hydration and barrier restoration stems from skin-conditioning fatty acids like oleic and linoleic acids, which increase moisture levels and decrease transepidermal water loss. Furthermore, its anti-aging properties are attributed to stimulating collagen production and potentially preventing wrinkling and sagging, partly due to its silicon content. It also assists in toxin removal and may offer some UV protection.

Key findings
- 01 Clinical application of a ferment-containing serum over eight weeks led to a 16% increase in average moisturization and an 11% improvement in barrier integrity on intact skin. For compromised skin (tape-stripped), barrier strength saw a 30% enhancement over the same period. This ingredient also significantly improved post-procedure barrier recovery following non-ablative laser treatments and 70% glycolic acid peels.
- 02 Both preclinical and clinical evaluations of ferment-containing creams revealed notable anti-inflammatory, anti-aging, and healing capabilities. Studies showed it enhanced collagen type I in ex vivo models, accelerated skin cell migration in vitro, and clinically decreased erythema, improved visible signs of aging, elevated moisture levels, and reduced transepidermal water loss (TEWL).
