🚫NEVER use the adhesive that starts to feel gummy! Because that means that he is already "polymerized" and it started the curing process!!!
🚫NEVER work with a small adhesive drop, because small drop cures faster and the adhesive won’t stay fresh for long, forcing you to put new drop every few minutes.
🚫NEVER dip the lash on the top of the adhesive drop, the top of the adhesive drop will never stay fresh because it is exposed to oxygen and might have started the curing / polymerization process.
🚫NEVER wipe the adhesive on any surface (work surface, eye pad, etc.) As soon as the adhesive comes into contact with a surface, the chemical reaction begins!
