Hydrogel eye patches are essential accessories to make your job easier while applying eyelash extensions. Hydrogel lash extension patches help separate the lower lashes so that they don't get in the way while applying lash extensions to the top lashes. Nanolash hydrogel patches for eyelash extensions feature a refined shape that can easily fit any eye. The package contains 50 pairs of hydrogel lash extension patches. Hydrogel eye patches also prove useful for separating the lower eyelashes during eyelash lift and lamination treatment, as well as during eyelash tinting as they protect the lower eyelid from debris.
