Microdermabrasion is a mechanical exfoliation method that resurfaces the skin by spraying fine crystals or using a diamond-tipped wand to abrade the stratum corneum. It improves texture, reduces fine lines, minimizes superficial pigmentation, and enhances product penetration. Enzymatic exfoliation (choice A) relies on proteolytic enzymes to digest keratin proteins. Chemical peels (choice C) dissolve intercellular bonds with acids like AHAs or BHAs. Ultrasonic exfoliation (choice D) uses low-frequency sound waves to loosen debris and dead cells. Microdermabrasion requires proper training, screening for contraindications such as active acne, rosacea, or thin skin, and adherence to infection-control protocols. Clients must be advised about post-care, including SPF use and avoiding harsh products. This treatment exemplifies applied sciences knowledge combined with practical esthetic skill.
