[Dot Matrix SkinLift] is a noninvasive skin care procedure, meaning there is no cutting of the skin to perform it, which utilizes high energy to tighten and tone the body and improve its contour.[Dot Matrix SkinLift] works by stimulating the under layer of the skin, known as the dermis and causes collagen creation, called neocollagenesis.This new collagen makes the skin look firmer & tighter and improves the overall texture of the skin and the body shape. Unlike lasers, Dot Matrix SkinLift procedure works on all skin types and colors.Generally patients will usually undergo 8-10 times with Dot Matrix SkinLift to see visable results. But some people may see differences/improvements just after 1-2 times of use. The Dot Matrix SkinLift stimulates a large volume of collagen in the deeper layers of the skin. Results develop over time and tightening and lifting result can be seen in up to 2 months.[Rechargeable]A full charge takes 3-4 hours and then it can work 30-45 mins.
