What chemical is primarily involved in peeling treatments?

The primary chemical involved in peeling treatments is AHAs, or alpha hydroxy acids. AHAs are water-soluble acids derived from fruits, and they are commonly used in chemical peels because of their ability to exfoliate the outermost layers of the skin. This exfoliation helps to remove dead skin cells, improve skin texture, and promote cell turnover, making them effective for treating concerns such as fine lines, sun damage, and hyperpigmentation.

In contrast, while BHAs (beta hydroxy acids) are also used for their exfoliating properties, they are oil-soluble and penetrate deeper into the pores, making them more suitable for acne treatments rather than for general peeling treatments. Retinoids, which are derivatives of vitamin A, can aid in skin cell turnover and collagen production, but they are typically used for their anti-aging and anti-acne effects rather than as primary agents in peeling solutions. Acne medications encompass a broader category and do not specifically focus on the peeling process, further distinguishing AHAs as the correct choice for this question.
