Microdermabrasion: This non-surgical cosmetic procedure helps to remove the outermost layer of dead skin cells. Exfoliation materials like aluminium crystals or diamond flakes are used along with a machine-based suction to gently lift up the skin. This skin treatment erases acne scars, removes blackheads and gives a polished look to the skin. A face treatment can last up to 30 minutes and if you're keen to get other parts of the body treated, then it may last an hour.
