The rated output of the Matsukaze LED light is DC5V/1A/5W. Therefore, the possibility of feeling heat from the LED light is low, and the difference between conventional moisture-curing glue and light-curing (LED) glue is very unlikely to cause any difference in the degree of damage to the lashes. Also, in light of the irradiation time, temperature at the time of irradiation, and hair cycle, it is unlikely that damage will be caused to the eyelashes or that damage will accumulate.
