All glues for eyelash extension contain the same ingredient, which is cyanoacrylate. Sensitive glues also contain this ingredient, however in a a lower percentage. They just produce lower fumes, hence are not as strong as the standard glue. Unfortunately, the retention may also be affected that's why we do not use any kind of sensitive glue in our salon. If your eyes are very sensitive, please ask your GP for an advise. You can also call our salon, and we are more than happy to answer all your questions if you are not sure if you can have the lashes done.
