Which ingredients are typically used in crystal microdermabrasion?

  1. Calcium carbonate and sugar

  2. Aluminum oxide, corundum, salt

  3. Silica and sponge

  4. Charcoal and clay

The correct answer is: Aluminum oxide, corundum, salt

Crystal microdermabrasion primarily utilizes aluminum oxide crystals, which are known for their effectiveness in exfoliating the skin. These crystals have a fine, granular texture that helps to buff away the outermost layer of dead skin cells, facilitating smoother and more refined skin. Corundum, which is a natural mineral composed of aluminum oxide, can also be found in some microdermabrasion products, enhancing their exfoliating power. Salt may be included in some formulations for its natural mineral properties, but the key component remains the aluminum oxide. This combination of ingredients is specifically geared towards providing a controlled and effective resurfacing treatment that targets issues such as fine lines, uneven skin tone, and superficial scars. The precise particle size allows for a customized exfoliation, making this option a common choice among practitioners.
