Clear Connection is a clear lash adhesive engineered for pro lash artists who need invisible bond — no white shadow, no gray cast on colored or sensitive sets. 1-second set time, 7+ week retention, 16-60% humidity range. All of our adhesives last up to 5 weeks once opened, and up to 3 months unopened. We recommend using a hygrometer in your treatment room to accurately gauge your humidity levels + choose the right adhesive, aka eyelash glue, for your studio. If your humidity is low, consider using a humidifier and a nano mister to expedite the curing process and decrease exposure to adhesive vapors.
