Which technique describes microdermabrasion?

Microdermabrasion is accurately described by the technique involving light abrasion on the epidermal layer of the skin. This method employs fine crystals or a diamond-tipped wand to gently exfoliate the outermost layer of skin, which helps to remove dead skin cells and promote cell turnover. The result is a smoother skin texture and an improved appearance of skin issues such as fine lines, sun damage, and acne scars.

Unlike other methods, microdermabrasion does not involve the use of strong chemicals, as referenced in the first option, which pertains to chemical peels. Deep tissue massage, mentioned in the second choice, is distinctly a technique focusing on muscle and fascia manipulation, having no relevance to skin resurfacing. The last choice regarding injecting nutrients into the skin relates more to treatments like mesotherapy or microneedling, rather than the exfoliation process that defines microdermabrasion. Thus, the correct description is light abrasion on the epidermal layer of the skin.
