How does chemical exfoliation differ from physical exfoliation?

Chemical exfoliation primarily involves the use of acids or enzymes to dissolve dead skin cells on the skin's surface. This process allows for a deeper penetration compared to physical exfoliation, which usually relies on manual scrubbing or abrasive materials to slough off dead skin. Substances such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) are common examples of the chemicals used in this method, interacting with the skin at a molecular level to promote cell turnover and enhance skin texture.

In contrast to this, physical exfoliation involves manual techniques, such as scrubs or brushes, to physically remove dead skin cells. While both methods can effectively improve skin appearance and promote a healthy glow, chemical exfoliation can often achieve results without the risk of irritation that might accompany vigorous scrubbing. Given this context, the emphasis on the role of acids in chemical exfoliation highlights its distinct mechanism compared to physical methods.
