영어 초록

The laser treatment and related energy devices targetingtattoo pigment particles has advanced much over the last few decades. To achieve selective photothermolysis fordestruction of the target and protection of surrounding normal tissues, sufficient energy to damage the target chromophore needs to be delivered with a pulse duration that is less than the thermal relaxation time of the target. A thermal relaxation time of tattoo ink particles is shorter than that of melanosome, around 10ns, suggesting that energy delivery in the picosecond range (10 -12 seconds) should be effective to selective photothermolysis. We here report 6 cases of patients with tattoos, including 5 patients of blue to black colored tattoos (2 females and 3 males, age of 23-45 years) on their upper extremities and trunk and 1 patient with black and red colored tattoo on her upper arm (56-year-old woman). They received 1 to 6 treatments with a 755-nm, 750 picosecond laser with a spot size of 2 to 3 mm, 1 to 2 passes and fluence of 2.68 to 5.25 J/cm2. All patients reported tattoo clearance of greater than 75% with no side effect. To our knowledge, this is the first case of successful treatment for red-colored tattoo using picosecond, 755-nm alexandrite laser(Picosure). Our study suggest this novel, picosecond 755-nm alexandrite laser is effective and safe for multicolored tattoos in Korean patients.
