Question: 1 / 400

What mechanical exfoliation technique uses a closed vacuum to shoot crystals onto the skin?

Microdermabrasion

Microdermabrasion is a mechanical exfoliation technique that employs a closed vacuum system to propel fine crystals onto the skin's surface. The purpose of this process is to exfoliate the outer layer of dead skin cells, promoting cell turnover and revealing a fresher, smoother complexion beneath. The vacuum aspect helps to remove the exfoliated skin particles and any impurities, making the treatment effective in reducing the appearance of fine lines, uneven texture, and certain types of pigmentation.

In contrast, chemical peeling involves applying a chemical solution to exfoliate and improve the texture of the skin, while dermaplaning uses a surgical scalpel to gently scrape away dead skin and peach fuzz without the use of any crystals or vacuum. A facial scrub typically consists of granular products applied manually to the skin to provide a similar exfoliating effect but lacks the vacuum technology of microdermabrasion.
