Both treatments are available and involve producing light energy which is then absorbed into the dark pigment of the hair to ultimately cause damage to the hair follicle. Hair growth is then reduced without damaging the surrounding tissue.
The main advantage of using Laser Hair Removal over IPL is that Laser technology is much more effective and achieves better results. Most patients experience permanent hair reduction after 6-12 sessions.
IPL is simply cheaper while Lasers are far more precise and can target more selectively coarse hairs while leaving the surrounding areas of skin undamaged. It can target larger areas faster as well in a fraction of a second. Plus it can be adjusted to suit your specific skin tone and hair color. IPL can burn darker skin tones while Laser is safe for all types.
The main difference between the two is Laser works on a single wave length of light which has a very concentrated beam and specific target. The color of your skin and hair color will determine the settings.
Lasers create more heat directed at the hair follicle hence better results because the heat is absorbed by the hair follicle and not the skin and there is a decreased risk of burning.
