Almost any type of tattoo, including permanent makeup, can be safely and effectively removed with laser treatments. Lasers work because different wavelengths of light are able to target different colors of tattoo ink. When the tattoo particles absorb the laser energy, they are broken up into tiny fragments which are carried away by the body''s natural cleansing process. Black ink is the easiest to remove, while red and orange are more difficult. Yellow ink cannot be removed with lasers at this time. Thus number of treatments for maximum improvement varies according to the location, age, depth and color of your tattoo
