Of 352 people getting a tattoo removed with the so-called Q-switched laser, just under half had their tattoos successfully eliminated after 10 sessions, and three-quarters after 15 sessions, according to the study led by Luigi Naldi, from Centro Studi GISED in Bergamo, Italy.
Sadick uses the Fraxel laser to remove diffuse wrinkling or discolouration; Thermage for skin tightening; sclerotherapy, which involves injecting a solution directly into the vein to treat varicose veins; the Q-switched laser, which fires very rapid pulses and blasts away pigment spots, and injections of fat to plump up the hands.
