Infrared 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 care the skin and improve its contour. Infrared 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, the infrared Dot Matrix SkinLift procedure works on all skin types and colors. Generally patients will usually undergo 8-10 times with Infrared 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.
