Our nail glue contains Ethyl Cyanoacrylate and Polymethyl Methacrylate (PMMA). Cyanoacrylates are not classic acrylates. However, PMMA is derived from a substance that may, in rare cases, cause reactions in individuals with acrylate allergies. Please consult your doctor in advance to be certain. It is also possible that people with allergies may react to other ingredients in nail products.
