Photofacial is a term for a skin treatment that uses some kind of light-based technology, primarily for boosting collagen, treating brown spots, and diminishing broken capillaries. Other names for photofacials are foto facials, facial rejuvenation and photo rejuvenation.
Usually, a photofacial means an IPL (intense-pulsed light) treatment at a medical spa.
An IPL photofacial can treat a variety of skin conditions such as brown spots, broken capillaries, spider veins, and facial redness. An IPL photofacial delivers a bright blast of light at very high energy levels through a hand-held device.
Some spas that have LED (light-emitting diode) equipment. It is usually called light therapy, and LED facial, or LED treatment, but it is sometimes called a photo facial.
However, IPL and LED are completely different, so it's extremely important to understand which photo facial technology is being used. That way you are more likely to get the results you hope to achieve.
