Broadband light technology generates broad-spectrum light waves that penetrate deeply into the lower layers of your skin. The light is changed to heat energy as it reaches beneath the surface of the skin. As this special type of light saturates the epidermis, chemicals in your skin change light energy to beneficial heat energy that immediately begins repairing damaged skin by stimulating collagen production. Collagen is a protein-rich, structural compound necessary for supporting all your body’s tissues. It is also essential for providing firmness, suppleness and strength to your facial skin. Skin naturally produces less and less collagen as we age, a major contributing factor to wrinkling, sagging, dryness, and unattractive spider veins.
