BBL Skin Tightening treatment utilizes advanced infrared light technology, and patient tailored filters to deeply heat dermal collagen while continuously protecting the treated epidermis with sapphire contact cooling for optical clinical endpoints, safety and comfort. With no need for a topical anesthetic, the energy is delivered in rapid, gentle pulses to promote contraction and partial coagulation of the collagen, initiating the body’s natural healing process, leading to the appearance of firmer tissue.
