Client conditions that should preclude cosmetic tattooing
Avoid cosmetic tattoo if the client:
- Is pregnant or breastfeeding
- Has a heart condition or pacemaker
- Has a condition or disease of the kidneys or liver
- Has a bleeding disorder or if taking anticoagulants (blood-thinning medications) including regular Aspirin.
- Has any personal or family history of Methemoglobinemia (blood disorder)
- Has any major medical condition
- Has serious allergies to any substances especially if hospitalisation was required
- Is under the age of 18
- Is prone to Keloid Scarring (raised scar tissue due to a paper like cut on the skin.)
If your client is unsure of any allergies to hair dyes or jewellery, it is always safer to do a patch test before going ahead with the procedure and wait 1 week for any reactions. Severe allergic reactions should occur within the first few days from the patch test (see below).
If a Nickel allergy has been diagnosed, it is possible that an allergic reaction can occur anytime within the following year and it can leave permanent side effects.
If the client has an allergic reaction to pigment, it will probably show up as a red, itchy rash. In some rare cases, the allergy might cause small bumps to form across the tattoo. It is important to know that not every skin condition that results from getting a tattoo, is an allergic reaction.
*Please see the medication chart included in your workbook manual.
The patch test should be done behind the ear area; proceed with the following steps.
- Set up your station as you normally would for a microblading cosmetic tattooing procedure
- Dip microblading blade in pigment (pigment should be in pigment pot)
- Gently penetrate the skin and make 2 incisions just outside hairline behind the ear
- Once the skin has been gently opened, massage pigment into area
- Clean the pigment using saline or water wipes
- Apply healing cream
- Allow 1 week to see if any allergic reaction occurs
Problems to note:
- Pigments sometimes will only react to certain parts of the body and may also have different healing outcomes. Also, some parts of the body may have more sun exposure thus affecting the healed result, and dependant on where the test patch is performed the skin may be thicker than the area being treated in the procedure.
- Although most treatments occur a week after the test patch, this timeframe may be insufficient as actual healing can take up to 3 weeks to 3 months, allowing for a stable result. Although rare, allergic reactions have been known to take place months and sometimes years after the procedure.
- The amount of pigment and surface area worked on during a test patch (usually 2 small incisions behind the ear on the hairline) will be significantly smaller than the procedure, therefore the body may not react to the test patch.
