BACILLUS/GLUTAMIC ACID FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

A postbiotic skincare ingredient derived from fermented glutamic acid using Bacillus bacteria, designed to optimize skin microbiome balance and barrier function. This water-soluble ferment filtrate acts as both a humectant and microbiome modulator, supporting beneficial skin flora while enhancing moisture retention. Clinical testing demonstrates significant improvements in skin brightness and barrier integrity within a two-week application period.

Summary

skin conditioning moisturizer/humectant microbiome modulator

Science

Mechanism of Action

Functions as a postbiotic agent that promotes beneficial microflora colonization while inhibiting harmful bacteria on the skin surface. Strengthens the stratum corneum through enhanced ceramide synthesis and improves skin elasticity by supporting natural renewal processes. Additionally acts as a humectant by binding water molecules in the upper skin layers, maintaining optimal hydration levels.
