Laser skin surgery

The color, or wavelength, of the laser chosen depends on the desired result, as some lasers target certain pigments better than others. While not suitable for every application, laser surgery does offer a number of advantages over traditional methods. For example, lasers create less bleeding, because they seal off blood vessels as they cut.

There's also a reduced risk of infection. A major benefit of lasers is their ability to cut in a precise manner, with minimal damage to surrounding or underlying tissue. For this reason, laser skin surgery tends to produce less scarring. Among the many applications of the laser are removing skin cancers and pre-cancerous growths; taking off benign growths like warts, moles, and skin tags; and eliminating brown spots.

Lasers can be used to resurface the facial skin, improving lines, texture, and age spots. Spider veins and rosacea (rose-AY-shuh) can also be addressed with this tool. One of the biggest advances is the use of lasers in treating birthmarks like port wine stains and hemangiomas (hee-MAN-jee-OH-muhz). They can also be used to remove or lighten tattoos.
