Laser removal of tattoos

Roy Geronemus et al. at the Laser & Skin Surgery Center of New York compared nanosecond and picosecond laser technology at different wavelengths, 532 nm, 755 nm and 1064 nm. The authors studied 44 subjects (53 tattoos) and concluded that picosecond laser is safe and effective in treating tattoos. They noted that most inks could be removed with the least amount of treatments using a combination of 755 nm and 532 nm. Wavelength 1064 nm would be preferred for tattoos with black ink in darker skin types.

Jeffrey Dover et al. also reported that a combination of 755 nm and 532 nm is effective in removing tattoos that contained black, blue, green, red, orange and yellow pigments.

Both groups found that the picosecond laser worked well in most skin types.

Pham reported that the diode laser 810 nm was safe and effective for removal of eyeliner tattoos. Pham’s study was the only study in literature addressing the safety of tattoo removal laser in areas around the eyes.
