Unfortunately there is no such thing as a true hypoallergenic glue. Every eyelash adhesive on the market is made of cyanoacrylate which is the cause for allergic reactions with clients. Some adhesives have lesser amounts of cyanoacrylate which are typically labeled as sensitive adhesives.
Due to the lower levels of cyanoacrylate, sensitive adhesives don’t have near the retention that we expect as a standard. With an adhesive with lower levels of cyanoacrylate you will typically experience a retention time of 1-2 weeks while our adhesive standard is an average of 3-4 weeks.
