Although the permanent cosmetics industry does not require a sensitivity test for possible allergic reactions, the manufacturer of the pigments that I use does recommend it, and I always err on the side of safety. Patch testing serves a dual purpose; it tests for adverse reactions and color outcome (pigment + skin undertones = the final color result). Patch testing is the only way to know how a specific color or color combination will heal in your skin. However, all this being said, a color patch test does not rule out reaction to future implanted pigments, though it is a good indication if a client will have any type of reaction to the products.
The patch test can be performed in an inconspicuous area on the body, such as the scalp, behind the ears, between the toes, or at the procedure site. The color patch test is normally a 1 week test.
An anesthetic patch test will be performed at the same time as the color patch test. Several drops of anesthetic will be tested in an area other than the one where the color has been placed. Antibiotic ointment will be placed on top of one of the color patch test areas.
After the patch test, the client will be instructed on “After Care.” These are the same after care instructions as when the client has the actual procedure.
A positive or allergic reaction will result in intense itching, abnormal redness, and nodule-like (bumpy) characteristics of the test site. If ANY of these characteristics occur, consult with your dermatologist and contact Beauty By Design.
