In what type of chemical peels does the protein coagulation in the skin turn white?

The correct answer pertains to Jessner and TCA peels, which are known to cause a distinct reaction in the skin during the peeling process. These types of chemical peels penetrate deeper into the skin compared to others and involve a blend of various acids, including trichloroacetic acid (TCA) and salicylic acid in Jessner's solution.

When applied, they create a reaction that leads to protein coagulation, resulting in the skin turning white in the areas where it is applied. This whitening effect is a crucial indicator that the chemicals are working effectively to remove the layers of skin, promoting new skin growth and improving texture and tone.

Other chemical peels, such as AHA (alpha hydroxy acids) and BHA (beta hydroxy acids), primarily work on the skin's surface and do not typically produce the same level of coagulation or immediate whitening. Options like glycolic and salicylic acid peels focus on exfoliation at a superficial level, while enzyme peels and lifts are generally milder and designed for different purposes, such as gentle exfoliation or lifting without causing profound changes like coagulation. Thus, Jessner and TCA peels are specifically recognized for this significant reaction, confirming their potency
