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
  • LVL CeraLashLift System Patch Tests include six single-use LVL CeraLashLift System Patch Tests (Steps 2 & 3) and six patch test instruction cards. These do not include LVL CeraLashTint
  • If performing the classic LVL treatment, use the use the classic LVL patch tests (pack of 5)
