Which method is used in dermabrasion?

In dermabrasion, a mechanical brush is utilized to exfoliate the outer layers of the skin. This method involves using a specialized rotating instrument that abrades the skin's surface, promoting the removal of damaged or scarred skin layers and allowing healthier skin to emerge. The mechanical action of the brush effectively smooths the texture of the skin, making it particularly useful for treating acne scars, fine lines, and uneven skin tones.

This technique contrasts with the other methods listed. Chemical peels involve applying a solution that chemically exfoliates the skin, while laser technology utilizes focused light to treat various skin imperfections. Microdermabrasion, while similar in that it also exfoliates, typically employs a less aggressive method using fine crystals or a diamond-tipped wand, resulting in less downtime and lower penetration than standard dermabrasion. Each method serves its purpose within cosmetic dermatology, but for dermabrasion specifically, the mechanical brush is the defining characteristic.
