Patch Testing Guidelines

Ever since lash artists' work came to a halt back in March 2020, we have encountered many questions and concerns regarding patch testing since the four-month lockdown period, we can’t say we’re surprised. It has been a confusing time for lash artists, and we hope to put everyone’s concerns regarding patch testing at ease. Below we have listed our patch testing guidelines for Lash Adhesive, as well as Lash Lifting and Tinting.

Cyanoacrylate is the main ingredient in lash adhesive and the cause for most reactions. It is an irritant for your skin, eyeballs and respiratory functions. If you are using an EU regulated adhesive, it will state this fact, alongside a big diamond with an exclamation mark inside it, on the bottle or packaging. For this reason, lash adhesive should not touch the skin, ever.

Patch testing for adhesive cannot provide a 100% conclusive result, this is because only a small amount of product is used. It is more likely for allergies and sensitivities to occur in clients who have been exposed to the product. This means a client who has been having lash extensions for a while are more susceptible than a new client who has never had them before.

  1. You do not need to patch test lash adhesive on clients; however, all clients should be offered the option of a patch test if they have any concerns.
  2. It is important that the client is fully educated of the potential risks involved with lash adhesive reactions for them to make an informed decision.
  3. A consultation form and patch test form must be carried out, documented and signed by both the client and the lash artist to confirm both parties understand and are happy to go ahead with the treatment.
  4. You must follow your insurers’ guidelines.

Important to note:

If your insurer says that you must follow the supplier’s guidelines, revert to points 1-3.

OR

If a patch test is required by an / your insurance company, follow the recommend procedure below:

  1. Carry out a consultation, explain patch testing to your client and then document.
  2. Ensure the lashes are clean and make up free.
  3. Protect the lower lashes with tape of pads.
  4. Attach 5-8 fine short lashes to the natural lash spaced along each eye.
  5. Complete the patch test form and ask your client to sign.

A patch test should be completed 24/48 hours prior to appointment/treatment. The client should be instructed to inform you if any reaction or sensitivity occurs. In extreme cases of reaction you should tell your client to seek medical advice. You should be readily available to remove the lashes using the proper technique. If no reaction occurs, the treatment may go ahead.

Patch testing for Lash Lifting and Tinting cannot provide a 100% conclusive result, this is because only a small amount of product is used. As mentioned earlier in this blog, it is more likely for allergies and sensitivities to occur in clients who have been exposed to the product. This means a client who has been having Lash Lifts or Lash Tints for a while are more susceptible than a new client who has never had the treatment before.

However, with that said, it is vital to patch test prior to carrying out the Lifted treatment. Most insurance companies require you to carry out a patch test to help prevent an allergic reaction from occurring.

  • Carry out a consultation
  • Always record the date of the patch test
  • Record where you have placed the products (see next step)
  • Place a small amount of product that will be used to either the wrists, inside of elbow or behind the ears, and allow to dry (Tint must be mixed first).
  • Always have the client sign to say that they have had the patch test.
  • When returning for treatment make sure the form is signed again and the results of the patch test are updated. Any reaction is likely to occur within 24-48 hours. Ensure the client is aware that the past test must be left on for 24 hours, if no reaction occurs it can be washed off. However, if a reaction does occur, they should let you know and seek medical advice. IF there are any signs of redness, itching or swelling the treatment must not be carried out.

We hope this has helped to clear up any worries you have had about patch testing … now let’s get back to lashing!
