For treating lines and wrinkles, a combination of skin resurfacing and skin-tightening procedures can be used or both can be accomplished with a more aggressive ablative laser, such as a CO2 (carbon dioxide) laser or Erbium YAG. The CO2 laser is also commonly used for the removal of warts and skin tags and for cutting skin in laser-assisted surgery. Non laser, light-based treatments, such as IPL and LED photofacial are less aggressive.
The most-commonly used lasers for the treatment of pigmented lesions, such as sun spots, age spots melasma and other forms of hyperpigmentation are the Q switch Nd: YAG and fractional lasers, along with non laser, light-based treatments, such as IPL.
Q switch Nd: YAG remains popular for tattoo removal, although some success can also be had with the use of IPL.
The success and safety of laser hair removal is highly dependent on the pigment present in both the skin and the hair of the patient being treated. For darker-skinned patients, the Nd: YAG and diode lasers are often the lasers of choice, and for lighter-skinned patients, IPL has proved effective.
There are many different modalities of light-based technology being used in the world of cosmetic surgery today. Though these methods are often referred to as “laser” procedures, the devices being used are not actually true lasers. These technologies include IPL, LED treatments, infrared energy-based technologies and radio-frequency based procedures.
