An allergic reaction to eyelash extensions is most typically a reaction to the active ingredient in the adhesive, cyanoacrylate. This reaction will typically start 24 hours after your lash appointment and presents as swollen and itchy eyelids.
It is important to understand that once this reaction has started, removing your lash extensions will not help. The reaction typically lasts 3-4 days and can be managed best with over the counter topical antihistamines, or medical treatment for serious cases.
Once you react to lash adhesives, it is possible you will be allergic to them all. We do, however, carry a hypoallergenic adhesive that uses a very small amount of the active ingredient. This adhesive is great for those with mild allergies or sensitivity.
