Abstract

A tattoo is a foreign material entered into the dermis by needle or some other trauma that results in a visible mark in the skin. either decorative or cosmetic tattoos or may be traumatic tattoos placed in radiation ports. There are many ways for tattoo removal one of them is laser treatment by Q-Switched Nd:YAG laser. This study was done in clinic medical – Mashhad Holy in Iran, from December 2021 to end Joule 2022. After clinical assessment of skin tattoo color and classification of skin color. (15) patients were divided by color ink. (7) patients with tattoo black, (3) patients with tattoo red, (2) patients with tattoo green, (2) patients blue, and (1) patient with tattoo sky blue.

According to Fitzpatrick classification 8patients were skin type (III), and 7patients were skin type (II). Laser parameter used: Q-switched laser wavelength 532nm for red tattoo patients, Q-switched laser wavelength 585nm for blue and green tattoos patients, Q-switched laser wavelength 650nm for sky blue tattoo patients, and Q-switched laser wavelength 1064nm for black tattoo patients, spot size (5-10) mm, R.R 1-2Hz, fluence 6J/cm2. Clinically good improvement. Physical properties have been studied for tattoo and laser treatment.
