Sutilains
What is Sutilains?
Sutilains consists of proteolytic enzymes derived from the bacterium Bacillus subtilis through fermentation processes. Classified as a skin conditioning and lytic agent in cosmetics, it primarily appears in exfoliating treatments, masks, and creams targeting rough or thickened skin. Functionally, it cleaves peptide bonds in proteins like keratin within the stratum corneum, the skin's outermost layer. This action loosens attachments between dead skin cells, enabling their natural shedding and revealing fresher skin beneath. In formulations, sutilains operates at low concentrations to provide mild exfoliation without mechanical abrasion, making it suitable for at-home or professional skincare routines focused on texture improvement and cell turnover support. Its enzymatic nature distinguishes it from chemical exfoliants, offering a biological approach to skin maintenance.

What is sutilains in skincare?
A proteolytic enzyme from Bacillus subtilis bacteria, used as a lytic and keratolytic agent to break down skin proteins.
Is sutilains safe for daily use?
It carries a low safety rating and is considered suitable in cosmetics when used as directed, with patch testing advised.
How does sutilains differ from other exfoliants?
Unlike acids or scrubs, it enzymatically loosens keratin bonds for milder, biological exfoliation.
