Subtilisin

Subtilisin is a proteolytic enzyme produced by Bacillus species through biotechnology. In skincare, it works as a pH-dependent enzymatic exfoliant, loosening protein-rich surface buildup to leave rinse-off masks and cleansers feeling smoother.

Not typically evaluated for comedogenicity — no standardized rating available.

Is Subtilisin a Good Ingredient?

It rates Fair because its enzymatic exfoliation can smooth texture in short-contact formulas, but strong clinical data for leave-on benefits are limited. As a protease, it may also irritate or disrupt the barrier if overused or at unsuitable pH.

Skin Benefits

It gently refines roughness to reveal a more polished, even-feeling complexion with minimal mechanical rubbing, though evidence for long-term skin benefits in leave-on products is limited.

Uses in Skincare & Cosmetics

It's often included in enzyme peels, exfoliating gels, and powder-to-foam treatments that are rinsed after short contact.

Safety

It may cause stinging, redness, or tightness, especially on sensitive or compromised skin and around the eyes; rinse-off use typically lowers this risk. Patch test if you're reactive and avoid using it alongside other strong exfoliants.
