pH Value of Tattoo and PMU inks

Too high or low pH-values can cause skin irritation. Ideally the value should be in the range of 5 - 8. We also assume this value will be adopted by future legislation and recommend to check the value of the main products along with the testing according to ResAP(2008)1.
