The Lasers have a fixed principle. Each Laser has a specific target called chromophore. This chromophore helps determine the depth and thus the use of a particular laser I skin / hair
Eg. DIODE laser (808nm) targets the chromophore (MELANIN) of the hair follicle, hence when used on the skin, it works effectively in permanent hair reduction without damaging the surface skin.
Thus lasers are more specific and effective in hair reduction than IPL (which is not a laser)
Another important aspect to look into when choosing the laser is the type of skin to be treated.
Few of the common and effective lasers used in various skin conditions are listed below
Lasers need special expertise and qualification to perform. They work best in the hands of a qualified dermatologist.
