How the Homedics Radiance Microdermabrasion device works is that it uses salon grade diamond tips to exfoliate the skin. The vacuum massage looks to remove the dead skin cells and stimulates the regrowth of the layer of skin. It's also interesting to know that Diamond-tip microdermabrasion is the most advanced technologies currently on the market. It's pain-free and is non-surgical, which means that there's no recovery time involved. Inside the box you receive two salon grade diamond tips which is ideal for normal and sensitive skin. There are 4 speed settings to suit your treatment, so you can start slowly and work your way up the speed levels. What I essentially like about the Homedics Radiance device is that you get a salon-grade treatment which means you get effective results right at home. There could be times where you may be busy for your beauty salon appointments, so ideally you can now look to rejuvenate your skin right at home. With the right tools, anything is possible.
