Q&A: Is there a test for eyelash extension allergies?
This is most consistent with a contact allergic dermatitis reaction. You are either allergic to a substance in the lash or the adhesive. The adhesive is more likely the allergen. Contact allergy tests are done by patch testing. The material tested is put on a piece of tape and kept on your skin (usually the back) for at least 2 days. You can perform your own patch test unofficially by putting the lash on your ankle or other skin area under medical tape or a band-aid for 2 days and see if the reaction occurs. If an adhesive is used separately for your lashes you can self patch that as well. If a self patch test shows a reaction you can find what ingredient is the culprit by more extensive patch testing at an Allergist or Dermatologist.
