What is a patch test?

A patch test is a preventive procedure that should be carried out at home before using any eyelash adhesive. When trying a new product such as an eyelash adhesive, is it very important that a patch test is carried out before you go on to fully use the product.

Carrying out a patch test helps prevent a reaction to the product’s formula and ingredients as it allows you to see how it suits your skin on a smaller area, before you apply it to somewhere as sensitive as your eye lids.

What you will need to carry out a patch test

  • Eyelash Adhesive
  • A cotton bud
  • A cotton pad
  • Baby or coconut oil

How to carry out a patch test

There are a a couple of ways in which you can carry out a patch test for strip eyelash adhesive, for optimal safety we recommend you do both methods before fully using the product. 

If you are testing a strip lash adhesive, you can either apply a tiny amount of glue to the outer edge of your eye along your natural lash line, without applying it all the way along. Again, leave this on for 24 hours and if you don’t have a reaction, you should be fine to apply your false eyelashes using the adhesive you have tested.

Another way is by applying a small drop of adhesive to the skin behind your ear using a cotton bud. This is probably the most common method of patch testing as it is a lot quicker and easier. Ensure you drop the glue directly behind the ear on the lower side as this area is fairly sensitive. Allow 24 hours to see if any reaction occurs.
