Bacillus Ferment is produced from fermenting Bacillus species — a genus of bacteria known for producing robust extracellular enzymes. The fermentation yields proteases and other enzymes that gently digest dead skin cell proteins on the skin surface, providing enzymatic exfoliation without the irritation of chemical acids. Particularly effective for dull, rough, or congested skin seeking gentle smoothing.
Key Skin Benefits
+ Protease enzymes — digest dead skin cell proteins
+ Gentle enzymatic exfoliation without acid irritation
+ Smooths rough skin texture
+ Supports healthy skin microbiome
+ Improves skin cell turnover naturally
Pros
+ + Enzymatic — no acid irritation
+ + Gentle enough for sensitive skin
+ + Natural protein-digesting action
+ + Supports microbiome balance
+ + Effective for body skincare
Cons
− − Less exfoliation power than AHAs
− − Enzyme activity varies by product pH
− − Must be properly formulated for stability
− − Results are gradual
