High-powered light in the near-infrared spectrum reaches past the skin’s top layer to gradually heat sub-dermal tissue. NIR therapy is powered by LED which has a gentler delivery than laser and will not damage tissue. This targeted light energy is applied with a precise hand-piece and it causes fibers to contract and tighten. The tissue is heated, but not destroyed, so it kick-starts cellular repair and collagen production. Unlike other treatments, the top layer of skin is completely unaffected. At the most, some users experience mild redness that fades quickly and it feels just slightly warm during treatment.
