BACKGROUND: Laser treatment of amateur tattoos on Fitzpatrick type V skin produces a considerable risk of complications because of the increased incidence of adverse pigmentary changes. The principle of selective photothermolysis predicts that the Q-switched alexandrite laser should be effective in removing tattoo ink with minimal side effects in patients with skin phototype V.
OBJECTIVE: To study the effectiveness of the Q-switched alexandrite (755 nm, 50 ns) laser in the treatment of amateur tattoos in Arabs in Kuwait.
METHODS: One hundred patients, each with multiple tattoos, were treated until total clearance. Fluences used ranged from 5 to 7 J/cm(2) with a spot size of 3 mm. Clinical evaluation was performed at baseline and at each follow-up visit until dyspigmentation resolved.
RESULTS: Total clearing was observed in all tattoos after an average of six sessions. Both tattoo clearing and post-laser hypopigmentation (29%) and hyperpigmentation (38%) increased with higher fluences.
CONCLUSION: In this prospective study, our findings suggest that the Q-switched alexandrite laser is an effective laser in removing amateur tattoos in patients with skin phototype V, but with a high incidence of pigmentary changes.
