A tattoo is the deposition of exogenous pigment into the skin or the accidental entry of pigmented material. The introduction of foreign substances into the skin can result in a range of adverse effects, including a toxic or immunologic reaction to the tattoo pigments, transmission of infectious disease, and the localization of skin disease within the tattoo. Tattoo removal may be required when complications develop. If an allergic reaction is noted, some cases resolve with topical or intralesional steroids, but permanent removal may be necessary. Treatment suggested are : Cryosurgery, dermabrasion, Q-switched ruby laser. Recently- Q-switched lasers (nanosecond duration, 10-9 seconds) ruby (694 nm), Q-switched Nd:YAG (1064 nm), Q-switched alexandrite (755 nm), Q-switched frequency-doubled Nd:YAG (532 nm), and the pigmented lesion pulsed dye (510 nm) lasers have been used to remove various tattoo pigments. Complication : Laser-induced photochemical changes can occur in tattoo inks resulting in irreversible immediate darkening of the tattoo. Pigments, including red, brown, and white, used for cosmetic tattoos are at highest risk for this type of reaction.
