What enzyme is commonly used in exfoliating products?

Papain is an enzyme derived from papaya and is widely recognized for its effective exfoliating properties in cosmetic formulations. This enzyme works by breaking down proteins that bind dead skin cells to the surface of the skin, promoting a gentle peeling effect. This process reveals a fresher, more radiant layer of skin beneath and helps to enhance overall skin texture.

In the context of exfoliation, papain is often preferred because it is both effective and gentle, making it suitable for various skin types. It can also help to reduce the appearance of blemishes and uneven skin tone while being less irritating compared to some physical exfoliants.

Bromelain, also known for its exfoliating properties, comes from pineapple and is not as commonly emphasized in cosmetic products as papain. Trypsin and pepsin, while they do have proteolytic activities, are not typically used in cosmetic exfoliation. Trypsin is more commonly associated with digestive processes, and pepsin is primarily involved in breaking down proteins in the stomach.

Thus, papain stands out as the enzyme of choice in exfoliating products due to its effective yet gentle exfoliation properties.
