LVL Patch Testing

Why patch testing is important?

Here at Nouveau Lashes, we’re constantly looking for ways to improve things. Patch tests are one of the most important aspects of LVL Lash Lift treatments. Patch tests are important for insurance reasons, the client’s experience (they could react to the products used during LVtreatments) and to demonstrate professionalism. In short, the patch testing process helps protect both lash artists and their clients as much as possible. 

LVL Patch Testing Process

  • Patch tests do not need to be carried out for every single LVL treatment
  • Patch tests are required prior to the first LVL treatment, then after 6 months (if they haven’t had a treatment in that time). Existing LVL clients will need to be patch tested ahead of using the new LVL CeraLashLift System
  • A patch test must be carried out if there are any changes to your client’s medical situation since their last treatment
  • Lash artists must wear gloves during LVL treatments and when patch testing clients, to prevent repeat exposure to treatment chemicals
  • To patch test for Step 2 LVL CeraLashLift and Step 3 LVL CeraLashFix or the classic LVL blister packs, our advice is to puncture the blister/sachet with the Pro Lash Tool to create a small opening that allows you to squeeze out just enough product
  • On average, you should able to perform up to 8 patch tests per LVL CeraLashLift sachet, and up to 6 patch tests per classic LVL blister pack
  • Once you have opened a blister/sachet for use as a patch test, we recommend you cover the opening with tape and store in a fridge for up to two weeks
Due to a directive from the MHRA, both classic LVL and LVL CeraLashLift System Patch Test Kits are no longer available to purchase . Our patch testing guidelines remain unchanged. See more info here here.
