BIFIDA FERMENT FILTRATE.

Essential / SKIN CONDITIONING

A potent postbiotic obtained through the fermentation of Bifidobacterium longum, designed to bolster the skin's biological defenses. This bio-active ingredient accelerates cellular repair while significantly reducing markers of sensitivity and external stress.

Science

It functions as a genetic upregulator for barrier-essential proteins including Filaggrin and Loricrin, strengthening the physical epidermis. Simultaneously, it stimulates Aquaporin-3 for deep hydration, neutralizes reactive oxygen species via antioxidant enzyme activation, and modulates pro-inflammatory cytokines to soothe reactive skin.

Key findings

  1. 01 Reduces Trans-Epidermal Water Loss (TEWL) by 20.6% and decreases visible redness by 21% over 28 days.
  2. 02 Improves skin firmness in 94% of users and accelerates cellular renewal in 95% of subjects after 8 weeks.
  3. 03 Significantly enhances barrier resilience and lowers sensitivity in reactive skin types.
