1. Chapter 10 Micro-dermabrasion Diamond micro-dermabrasion

2. Diamond micro-dermabrasion 1 Uses rotating steel heads encrusted with fragments of real or manmade diamonds. Treatment is gentle; you have control over the amount of pressure used on the skin so you can reduce pressure on sensitive areas such as the neck and eye area. The slower the speed of rotation, the more abrasive the treatment; the faster the speed, the more superficial the treatment. In some machines dead cells are sucked away by a vacuum; in others the cells have to be wiped away.

7. Precautions 1 Examine and test the machine. Carry out a tactile sensitivity test. Ensure crystal flow is functioning. Ensure skin is completely dry. Adjust pressure for sensitive areas. Do not work backward and forward over the area but work in lines in the same direction from one starting point. Treat both sides of the face equally. Do not over treat. Be alert to contra-actions.

8. Precautions 2 Adjust use of pressure for sensitive areas. Move the rotating head in a circular motion, following the direction of rotation of the head. Do not work back and forward over the same area; keep the head moving.

9. Preparation of the working area Place the machine on a stable base on the correct side of the couch. Check plugs, leads and connection of the nozzle. Select the appropriate diamond head for the area you are treating. Test the machine. Set controls to zero. Prepare the couch with clean linen and towels. Prepare the trolley with pre-treatment products, post- treatment products, soft brush and gauze to remove dead skin cells and the consultation record.

10. Preparation of the client Carry out a consultation – discuss effects and outcomes. Check for contraindications. Remove contact lenses and jewellery. Position the client comfortably. Protect hair and clothing. Explain to the client that they may feel a slight prickling sensation. Carry out a tactile sensitivity test. Cleanse and tone the skin. Carry out a skin analysis.

11. Treatment technique 1 Ensure speed control is at minimum and select the direction of rotation; place the head onto the neck and gently increase the speed. Place a finger to the side of the area to be treated; work in small circular movements away from the finger so the skin is lifted upwards and outwards. Be alert to contra-actions. Continue working upwards and outwards; change the direction to work up the other side of the face; cover the whole face and neck once or twice. Reduce the speed to zero and switch off the machine.

12. Treatment technique 2 Brush away remaining dead skin cells. Apply appropriate products. Update the consultation record.
