If I have had an allergic reaction to eyelash adhesive before, will you do a patch test on me?

Unfortunately that answer is no, the reason being is because every adhesive has a main ingredient that contains cyanoacrylate in it, which is a compound that is easily polymerized and are used to make quick-setting adhesives. Although you may not have a reaction to the patch test, you most likely will have a reaction once you receive a full set and unfortunately we will want to avoid that at all costs.
