Which method is commonly used for exfoliating dead skin cells?

Microdermabrasion is a well-established method for exfoliating dead skin cells through a process that involves the use of fine crystals or a diamond-tipped wand to gently abrade the skin's surface. This technique not only removes the outer layer of dead skin cells but also stimulates the underlying layers, promoting skin turnover and enhancing the appearance of the skin. It is particularly effective for improving texture, reducing the appearance of fine lines, and addressing issues like hyperpigmentation.

Other methods listed, such as hydration therapy, cleansing, and massaging, play important roles in skincare but do not specifically target the removal of dead skin cells in the same effective manner as microdermabrasion. Hydration therapy focuses on adding moisture to the skin, cleansing aims to remove dirt and impurities, and massaging helps with circulation and relaxation but does not exfoliate in the same way. Hence, microdermabrasion stands out as the most effective choice for the exfoliation of dead skin cells.
