When a chemical peel denatures the keratin protein, it is also called what?

When a chemical peel denatures the keratin protein, it is referred to as "frosting." This term describes a specific reaction that occurs during the application of certain chemical agents, particularly when they are strong enough to affect the upper layer of the skin. The denaturation of keratin proteins leads to a visible whitening or "frosted" appearance on the skin's surface, indicating that the chemical peel has penetrated sufficiently to alter the structure of the keratin, which is a key protein in the skin.

This frosting effect is often a desired outcome during deep peels, as it signifies that the treatment is working effectively to remove dead skin cells and promote cell turnover, leading to rejuvenated skin. The appearance of frosting can also help practitioners gauge the appropriate level of peel depth and guide them in achieving the desired results for the patient. Understanding this concept is essential for those in aesthetic practices, as it informs treatment techniques and expected outcomes.
