Evaluate the impact of skin tones on human body temperature during laser tattoo removal
摘要
Recent literature on laser tattoo removal focuses more on removal methods and systems than on side effects, such as increased temperature on tissues and ideal treatment parameters. This study aims to measure the surface temperature during the process of removing the eyebrow tattoo. The study was conducted on 55 patients between the ages of (22 and 43) years with five shades of recognized skin tone. The treatment was accomplished by a 1000 mJ YAG (PHI laser system) laser with pulse repetition rate of 3 Hz, and a spot size of 4 mm. The surface temperature of the skin during the tattoo removal process was measured using a FLIR thermal camera. The results were analyzed by testing the normal state of the distribution. The tests of Shapiro Wilk and Kolmogorov–Smirnov were used. All patients finished full treatment to achieve the goal of complete removal. After comparing the temperature, the results showed a significant effect of the skin nature and skin tone of the patients on the temperature distribution on the skin, patients with a darker degree of skin showed greater energy absorption and an urgent rise in temperature. This is why there is an urgent need to provide a reference that accurately illustrates the effect of temperatures and the selection of the right ones for each skin tone.
