There are several ways to lighten scars. For example, old acne lesions often look like dimples in the skin, which means they can be filled in locally. Elevated scars or scars that have a red color, in turn, are better off with Infini treatment, fractional laser or a combination of both. That first one is a high-intensity radiofrequency treatment combined with microneedling. the heat stimulates the repair mechanism, while the tiny needles promote the production of collagen and elastin. Thus, the skin will repair itself, as it were. The fractional laser makes small wounds, as it were, causing the skin to produce its own collagen and replace the damaged tissue with new and smooth tissue.
