The diamond-tip device offers a more precise exfoliation and relies on the technique of a skilled service provider to apply pressure with the diamond tip to gently remove the outer layer of the skin. It enables the practitioner to control the entire treatment process while the device sucks up the dead skin cells.
Whereas the crystal device blasts the skin with aluminum oxide crystals while also vacuuming up the dead skin cells and crystals. This treatment is reliant on the device, leaves little room for the practitioner’s skill, and does not remove all used crystals from the skin’s surface.
