taken. Patient goggles or eye shields, as well as operator face masks are recommended when treating with crystal based systems. Alternatively, microderm crystals can be safely replaced by the roughened surface of a diamond tip microdermabrasion system. The newer diamond based systems like Vacubrasion utilize a fine diamond dust that is essentially electroplated onto a stainless steel round tip that comes in contact with the skin. Microdermabrasion media Aluminium oxide crystals: 100 micrometres; aluminium oxide is relatively chemically inert and generally recognized as safe. Bristle tips: bristles are pliable, so they move with the skin allowing for aggressive treatments without added irritation. Diamond tips: can be natural but usually synthetic for lower costs; erythema (Redness) is partially due to circulation rather than only irritation. Liquid: water-based sprays in combination with a rough plastic tip spray liquid against the skin to help gently exfoliate. Magnesium oxide Organic grains: used to buff and polish; made from trees, plants, agricultural crops, straw, reeds, maize, sunflower or cane sugar. Sodium bicarbonate and sodium chloride crystals.
