Final answer:
Estheticians use alpha hydroxy acid, glycolic acid, or lactic acid to perform exfoliation, a process that removes dead skin cells and improves skin texture.
Step-by-step explanation:
Estheticians perform exfoliation using alpha hydroxy acid, glycolic acid, or lactic acid. This process involves the removal of dead skin cells from the surface, promoting cell turnover and contributing to the enhancement of skin texture and appearance. Chemical exfoliants like the ones mentioned are often preferred for a more profound exfoliation than physical ones, such as scrubs. Exfoliation not only improves skin texture but also can reduce the appearance of fine lines, wrinkles, and improve skin hydration when followed by appropriate moisturizing products.
