Which of the following is a common reaction to a chemical peel?

A common reaction to a chemical peel is mild dryness. After a chemical peel, the skin typically goes through a process of exfoliation and renewal, which often leads to temporary dryness as the top layers of dead skin are sloughed off. This dryness can be managed with appropriate moisturizers and is usually a sign that the peel is effectively working to rejuvenate the skin.

Severe itching, increased oiliness, and acne breakouts are not typical responses associated with a chemical peel. While some individuals might experience irritation or discomfort that could provoke mild itching, it shouldn't be severe. Increased oiliness is contrary to the effect of a chemical peel which aims to exfoliate and improve skin texture. Acne breakouts might occur due to other skin conditions or factors, but they are not a direct or common result of the peeling process itself.
