This is a water-soluble Lash Lift adhesive for attaching lashes onto silicone shields. How to use? Apply in thin layers and wait until the glue is completely dry (test it by touching with your finger - once dry it is no longer sticky) before adding another layer. Use 2/3 layers for best results. If you brush lashes up and isolate in one go (one layer of glue) then add one more layer once you have finished separating lashes. Two layers of properly applied glue is enough to prevent lashes from coming off the shield.
