Name a contraindication for chemical peel treatments.

Active infections or open wounds on the skin serve as a significant contraindication for chemical peel treatments because they can exacerbate underlying conditions and lead to further complications. When performing a chemical peel, the skin is chemically exfoliated, which can make the skin more vulnerable to infection. Open wounds are already a point of compromise in the skin's barrier, and introducing chemicals in that area could lead to increased irritation, delayed healing, or even systemic infections.

In contrast, while certain skin conditions, such as dry skin, may require careful assessment before treatment, they do not inherently disqualify a person from undergoing a chemical peel. Normal skin is typically suitable for treatment, depending on the peel's strength and type. Previous skin treatments may raise certain considerations, but they do not categorize a patient as having a contraindication unless they are recent or particularly aggressive treatments that might affect healing or skin integrity.
