Protease

Explained

These enzymes break down protein into smaller peptides and amino acids. They also encourage the formation of new protein.

Our skin uses peptides, amino acids, and protein for maintaining healthy skin cells.

Protease work by breaking peptide bonds in protein with hydrolysis. This is the process of breaking bonds using water.

An in-vitro study (not done on a living organism) found a blend of 3-protease decreases skin inflammation by mitigating the effects of other proteins.

One manufacturer that uses subtilisin, a protease from Bacillus subtilis, claims this ingredient is exfoliating, promotes cell regeneration, and is a good substitute for AHAs. Further research is needed to back up these claims.

Fun fact: The human body contains ~641 protease genes.
