Keratinase

1. Definition Keratinase:

Keratinase is an enzyme that breaks down keratin, a protein found in skin, hair, and nails. In cosmetics, keratinase is used to exfoliate and remove dead skin cells, improve skin texture, and promote cell turnover.

2. Use:

Keratinase is commonly used in exfoliating products such as scrubs, peels, and masks. It helps to smooth and rejuvenate the skin by breaking down the keratin protein that binds dead skin cells together. This process allows for easier shedding of dead skin cells, revealing fresher, brighter skin underneath.

3. Usage Keratinase:

When using cosmetics containing keratinase, it is important to follow the instructions provided on the product packaging. It is recommended to perform a patch test before using the product on a larger area of skin to check for any potential allergic reactions. It is also important to avoid using keratinase products on broken or irritated skin, as it may cause further irritation.
