IPL Treatment Vs IPL Photofacial - What is the Difference?

The names are different, the treatment is not. This is a generic name to denote cosmetic treatment of the face with either a laser or an IPL to improve color and texture, and a little collagen stimulation.

IPL, which stands for Intense Pulsed Light treatment, is the same as a photofacial. The name photofacial is used more as a marketing term for the same procedure. An IPL Photofacial will treat sun damage, rosacea, age spots, wrinkles, and more. 

Both IPL and photofacial are the same treatment.  There are just two different names for the same procedure.

It's interesting that the two categories have very different satisfaction levels on this site, we would not have guessed that.
IPL stands for "Intense Pulsed Light" and the term is generally used to refer to a physical piece of equipment. "Intense Pulsed Light" is the type of light used by these pieces of equipment (there are many different manufacturers.
"Photofacial" (fotofacial) is generally used to describe a light based (laser or IPL) facial treatment to address sun spots, redness or fine lines.
In some cases these terms are used interchangeably (I had an IPL treatment today), but will be able to keep them straight if you just think of a light based piece of equipment as an IPL and a light based treatment as the photofacial.

IPL stands for Intense Pulsed Light IPL is a non-invasive technology that can correct a variety of skin conditions, such as hyper pigmentation, birthmarks, broken capillaries and vascular lesions. Some devices have a photorejuvenation program or different handpiece that can be used to stimulate the collagen production and improve the skin texture. In this case the procedure is considered an IPL Photofacial, or IPL Photorejuvenation.
