What effect does a strong acid have in beauty therapy?

A strong acid in beauty therapy typically serves a specific purpose due to its chemical properties. When used correctly, it can have beneficial effects rather than being considered purely corrosive and useless. In the context of beauty therapy, one of the primary roles of strong acids is to aid in exfoliation. This process involves the destruction of dead skin cells on the surface of the skin, promoting cell turnover and revealing fresher, smoother skin underneath.

For example, alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs), which are often used in chemical peels and other treatments, effectively help in exfoliating the skin. They are categorized as strong acids but are safe and beneficial when applied properly in controlled environments by trained professionals. Thus, these acids can improve skin texture and clarity, proving their usefulness in beauty therapy rather than being simply corrosive.
