http://ckgbooks.com/anja/501 People can develop an allergy to anything, anytime; however, pigment allergies are considered rare. Some doctors recommend that people with environmental allergies or allergies to conventional makeup have permanent cosmetic procedures because they can replace cosmetic products that people are sensitive to. While allergic reactions to any type of tattooing pigments on the body or on the face through cosmetic tattooing may occur at any point in time, they are extremely rare. All of our clients are offered a patch test. If you are concerned about allergic reactions, please ensure you proceed with the patch test. Also, the pigment ingredients are printed on the labels, ask to see the bottle if you have any concerns.
