Final answer:
Microdermabrasion is the mechanical exfoliator that involves shooting aluminum oxide crystals at the skin. It is a non-invasive procedure used to rejuvenate the skin and improve its texture.
Step-by-step explanation:
The mechanical exfoliator that involves shooting aluminum oxide crystals at the skin is called microdermabrasion. Microdermabrasion is a non-invasive procedure used to rejuvenate the skin and improve its texture.
During microdermabrasion, a device sprays tiny crystals of aluminum oxide onto the skin, removing the surface layer of dead skin cells and stimulating the production of collagen. This process helps reduce the appearance of fine lines, wrinkles, acne scars, and uneven skin tone.
Microdermabrasion is often performed by dermatologists or aestheticians and can be done with different levels of intensity, depending on the individual's skin type and concerns.
