Efficacy varies with amount of ink deposited in tissue; effective with multiple treatments
TUESDAY, July 7, 2015 (HealthDay News) — The effect of the 1064-nm Q-switched Nd:YAG laser on tattoo removal varies with the amount of ink deposited in the tissue, according to a study published online July 2 in the Journal of Cosmetic Dermatology.
Agata Mankowska, Ph.D., from the SALUS Medical Clinic in Poznan, Poland, and colleagues examined the efficacy of tattoo removal treatments using the 1064-nm Q-switched Nd:YAG laser among 64 patients with 75 unwanted tattoos. Tattoo clearance was assessed according to color intensity for 34 patients in group I (black) and 41 patients in group II (grey).
The researchers found that after the first treatment session, the median of clearance was 30 percent in group I and 50 percent in group II. After the second treatment session, the median increased to 40 and 70 percent, respectively. The highest number of treatments was seven in group I and five in group II, after which, the median of clearance increased to 75 and 90 percent, respectively.
“Our study showed that effects were dependent upon the amount of ink deposited in the tissue,” the authors write. “The study showed that old amateur gray tattoos and tattoo received by techniques such as shading achieved the quickest and the most efficacious results.”
