This page provides you with information on what a patch test is, why we perform them, and how to perform one yourself at home.
A patch test is a precautionary procedure which is performed to determine the reaction of your skin when a certain substance comes in contact with it. Your skin can show an allergic reaction such as inflammation, redness, itchiness, blisters, or a rash. This is called contact dermatitis.
A patch test is a safety procedure to ensure that a person is not allergic to any of the pigments, makeup products or anaesthetic used. Additionally, it also helps the artist and the client to choose a color or a combination of colours that would produce the best results.
A patch test needs to be completed at least 48 hours before the procedure.
We will agree and inconspicuous area to perform the patch test. This area will be cleaned using alcohol.
A topical or prick patch test will be conducted and a small amount of the pigment, anaesthetic, makeup will be placed on the skin or on the puncture site of the prick test.
If a reaction is observed, it might not be possible to perform a PMU procedure.
Should you choose not to undergo a patch test you will take full responsibility and all the risk should any adverse reaction happen during or after the treatment.
Choose the area(s) where you would like to complete the patch test and clean the area using the alcohol wipe.
We recommend using an area on your inner arm for the anaesthetic. However, for the pigmentation, you may wish to do this in an inconspicuous area, for example, behind your ear. This is because you may have a very small dot of pigment left on the skin. This will eventually fade.
Remove the top of the skin prick and gently apply the needle to your chosen patch test area.
We recommend drawing circles on the patch test area before you prick the skin, and prick within the the circle. This is so that you don't forget where you have punctured the skin.
Make sure you fully puncture the skin to ensure that the anaesthetic and pigment penetrate the skin.
You will have been provided four test pots. Each test pot contains either anaesthetic or pigment. Each pot contains:
1. Primary anaesthetic (white cream)
2. Secondary anaesthetic (either pink or blue gel)
3. Inorganic pigment (no specific colour)
4. Organic pigment (no specific colour)
Using separate cotton sticks for each test pot. Dip the stick and apply the anaesthetic or pigment to the prick test area.
Do not reuse the cotton stick. Ensure you use separate cotton sticks for each pot.
Apply the transparent protective bandage over the prick test area(s) and leave on for at least 24 hours.
If your skin shows no reactions, we can proceed with the procedure. However, if your skin shows any allergic reaction, then it is not safe to get any cosmetic tattoos.
The signs of an allergic reaction may include:
After 24 hours please contact the clinic and confirm the result of your patch test.
