Laser treatments are used for skin resurfacing, laser vein treatment, tattoo removal and other cosmetic surgery treatments. The main difference between the types of lasers is the wavelength used to target the skin. Different lasers can be combined to achieve the desired results. Fine lines and wrinkles are treated by a CO2 or Erbium laser while skin tightening can be achieved by a CO2 laser. Vascular lesions are treated with Intense Pulsed Light (IPL) lasers and tattoos can be removed using a CO2 or Nd:YAG laser. The laser is focused on the targeted area and ablative lasers vaporize the top layers of the skin while non-ablative lasers go deep into the skin.
