Liposuction incisions are very small. They usually measure less than one inch in length. Because they are so short, the incisions are made in areas that are relatively visible. Initially, you may see short red lines or spots. As new collagen forms in the skin, these minor blemishes will gradually lighten. Once the skin is healed, about two weeks after the procedure, you can begin a scar treatment program using massage, silicone sheets, or a scar cream.
