Green Flash complies with European regulations and contains no sensitizing substances such as the methylacrylate monomers found in many conventional gel nail polishes. Many of our customers testify to the safety of our products, which they use without risk, particularly after experiencing allergies to other types of gel nail polish. 

However, as allergic phenomena are not specifically linked to chemical ingredients, we cannot guarantee that you will not have a reaction to any other ingredient, even natural ones. Should this be the case, please do not hesitate to contact us 🌸
