What is the primary method used in chemical peels for acne treatment?

The primary method used in chemical peels for acne treatment involves the use of acids for deep exfoliation. This approach is designed to remove the outer layers of dead skin cells, unclog pores, and reduce the occurrence of acne. Acids penetrate the skin to dissolve the bonds holding skin cells together, allowing for improved skin texture and tone.

Chemical peels typically utilize products like salicylic acid or glycolic acid, which are particularly effective in treating acne. These acids not only help in exfoliating the skin but also can have anti-inflammatory properties, reducing redness and irritation associated with acne breakouts. The deep exfoliation from chemical peels can lead to clearer skin over time, making it a favored treatment in acne management.

In contrast, physical exfoliation involves using abrasive materials to scrub away dead skin, which may not be as effective as the chemical process in targeting deeper issues related to acne. Moisturization of the skin is important for maintaining hydration and supporting the skin barrier but doesn't directly treat acne through exfoliation. The application of oils generally focuses on hydration and can sometimes clog pores, which is counterproductive to acne treatment. Thus, the use of acids for deep exfoliation stands out as the most effective method in this context.
