UltraSlim Cold Light is an FDA-cleared, nonsurgical body contouring procedure that uses a proprietary red-light technology known as photobiomodulation to reduce the fat layer just under the skin.Â
Unlike many nonsurgical fat reduction procedures (like CoolSculpting or UltraShape), UltraSlim doesn’t destroy fat cells, nor does it remove them, like surgical liposuction does.
UltraSlim uses its LED red light energy to induce lipolysis in fat cells. The light signals fat cells to go into “starvation” mode, creating a transitory pore in the cell membrane that releases fatty acids and triglycerides, causing the fat cells to shrink.Â
Those liberated fat cell contents are picked up by the lymphatic system, processed by the liver, and excreted naturally over the coming months.
Six weekly sessions are typically recommended, and its body-slimming effects are said to be permanent, as long as you maintain a stable weight. Â
UltraSlim is often paired with its sister treatment, UltraSmooth, which improves the appearance of cellulite by relaxing the connective bands that cause dimples.
RealSelf Tip: Some providers claim that UltraSlim also delivers skin rejuvenation benefits by stimulating new collagen and elastin production. However, Dr. Lorrie Klein, a dermatologic surgeon in Laguna Niguel, California, says that the collagen and elastin boost provided by red light therapy is minimal, compared to other treatment modalities.Â
