Understanding Keratolytic Agents in Skincare Products

Keratolytic refers to substances that break down keratin, a protein found in skin, hair, and nails. These substances can be used to soften or remove thickened skin, such as calluses or corns, or to loosen dead skin cells.

Examples of keratolytic agents include:

1. Salicylic acid: A common ingredient in over-the-counter treatments for calluses and corns. It works by dissolving the keratin protein that makes up the skin's outer layer.
2. Glycolic acid: A type of alpha hydroxy acid (AHA) that is also used to exfoliate and soften skin. It works by breaking down the bonds between amino acids in keratin, causing the skin to peel off.
3. Urea: A natural substance found in urine that has keratolytic properties. It is often used in creams and lotions to soften thickened skin.
4. Enzymes: Some enzymes, such as papain and bromelain, have keratolytic activity and can be used to break down keratin proteins in the skin.

Keratolytic agents are commonly used in skincare products to help remove dead skin cells and improve skin texture and appearance. However, it's important to use these products carefully and follow the instructions to avoid irritating or damaging the skin.
