DPL, Dye Pulse Light, is an upgraded version of photorejuvenation technology. Compared with the traditional IPL technology, it is less painful but more effective on pigmentation, hair removal, acne, redness reduction, and skin rejuvenation. DPL uses the high-energy spectrum of selected light to absorb melanin. DPL stimulates the production of new collagen. It can also effectively enhance the elasticity of the skin and smooth the facial fine lines.
