Super Bonder 10ml, is used 2-3 minutes after drying on the base of the lash to cure the glue. Use a micro swab or lip brush to apply at the the base of the lash extension and dry for 1-2 minutes. 1 drop on a lip wand is enough. This product cures the glue but also adds elasticity to the bond giving it more flexibility and therefore increasing retention. The lash bond does not get brittle and break and has flex for more durability.
