Enzymes Bon Exfoliant Hydratation Enzymes at a glance A vast group of proteins Serve as catalysts in chemical and biological reactions Are used in skin care to prompt exfoliation Their actions are affected by temperature and pH Enzymes description Enzymes are a vast group of proteins. All living things produce enzymes and they act alone or with other ingredients as catalysts in chemical and biological reactions- including those in skin cells. Enzymes are used in skincare products to prompt exfoliation. Most enzymes are finicky about how and under what conditions they will act. Sometimes several enzymes are required to carry out a particular reaction, and their actions are affected by temperature and pH. Some enzymes depend on the presence of other enzymes, called coenzymes, to function, or they depend on a specific body temperature. It would require an exceptionally complicated process to stimulate enzyme activity via topical application to skin. Enzymes are divided into six main categories: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. The names of most, but not all, enzymes end in -ase.
