What is Photorejuvenation used for?

Photorejuvenation (IPL- Intense Pulsed Light) laser treatments are most commonly used for:

Lightening and removing “sun spots”, “age spots”, and brown blotches on the face, neck, chest, hands, and other areas of the body
Lightening and reducing redness, rosacea, dilated blood vessels, and “broken” blood vessels on the face, neck, and chest
Helping to control flushing
It also has a lesser effect of improving skin texture through collagen stimulation and improves pore size minimally by temporarily reducing oiliness

Photorejuvenation, when done properly, almost always consists of a series of 3-5 treatments, usually one every three to six weeks. The benefits of photorejuvenation treatments are achieved with little discomfort and minimal risk.
How does the IPL photorejuvenation laser treatment improve the appearance of blood vessels, rosacea, and age spots/freckles?
The light beam passes through the skin and is absorbed by either hemoglobin or melanin resulting in damage to the vessel wall or fragmenting of melanin pigment. These tiny vessels and the melanin pigment are then absorbed by the body, rendering them less visible.
The laser/IPL device emits a range of lightwaves that are then tuned and targeted at hemoglobin (the red blood cells in the blood vessels) or melanin (the brown pigment in freckles and age spots).
