Intense Pulsed Light (IPL), also known as Photofacial, is a nonablative mixture of many wavelengths of light which works beneath the skin's surface to greatly reduce brown spots, discoloration, redness, and broken capillaries.
Photo rejuvenation with IPL also improves skin tone and texture while minimizing fine lines by inducing significant structural change in the epidermis and dermis.
Generally, a series of three to six IPL treatments is needed to gradually give your skin a more homogeneous appearance. Further improvement can be achieved by combining IPL with treatments such as microdermabrasion, chemical peels, and BOTOX®.
