We apply this sealer after every application of eyelashes with a microswab. We dab it at the base of the lashes to ensure that we don't close our fans. IntelliSeal decreases fumes for our clients and also helps to cure fresh adhesive. The binders in the sealer also create longevity and longer retention for our clients. We often sell this product as an aftercare item OR sell the natural touch and perfect touch mascaras that feature IntelliSeal in them.
