The drying time of your lash glue is affected by the humidity level in your environment. In a drier environment, the glue takes longer to dry, while high humidity levels can cause the glue to dry more quickly. Additionally, temperature also plays a role in glue performance. Higher temperatures can cause the viscosity of the glue to decrease, making it thinner and more prone to melting. Melting can cause the glue to become more liquid and dry faster. To ensure optimal glue performance, it is recommended to work in a well-ventilated environment at a temperature between 65ºF to 73ºF.
