Prolong life of eyelash extension by applying a silicon coating that protects the glue from oil, moisture and humidity. Recommended for use as a protective coating sealant used 2 to 3 times per week.   Increase the bonding strength. Can also be used to avoid mascara smudging. Provides a beautiful glossy shine to the extensions.   Great for eyelash extension lovers who swim or use steam rooms regularly.   Use of this sealant is the most essential part of aftercare for semi-permanent eyelash extensions.
