Protease

What Protease is & what it does

A protein-digesting enzyme that gently loosens dead surface cells, refining texture and brightening dull skin. It offers mild, non-abrasive exfoliation.

What does Protease do in skincare?

Protease is an enzyme that breaks down proteins, and in skincare it is generally included for a gentle exfoliating or smoothing effect by helping loosen the bonds between dead surface skin cells. It offers an enzyme-based alternative to acid or scrub exfoliation. The specific behavior depends on the formula and concentration.

Is Protease safe?

Protease is widely used in cosmetics as an enzymatic ingredient and is generally regarded as safe at the levels used in skincare products. Because enzymes can be irritating or sensitizing for some people, patch testing a new product is sensible. For specific skin concerns, it is best to consult a qualified professional.

Is Protease natural or synthetic?

Protease can be either, depending on the source. Many cosmetic proteases are produced through microbial fermentation, which is a biotechnology process, while some are derived from plant or other natural sources. The INCI name alone does not specify the origin, so the manufacturer is the best reference.
