Mascara may be used on all eyelashes, from inner to outer corners. The mascara brush is dipped into a clean tube of mascara, applied close to the base of the lashes and worked out to the tips. Mascara wands are made of plastic and should never be shared. Mascara can be applied to the top eyelashes for a \’heavy-lidded\’ look, or to the bottom lashes to widen the eyes. It is usually applied to curled lashes and may be preceded by a lash primer. The desired lengthening effect is achieved by reapplication of the mascara in 2-3 minutes. The moisture in some mascaras and primers can cause lashes to uncurl during application, which is easily solved by using a waterproof mascara with a drier formula.
Waterproof mascara should be carefully removed in order to limit eyelash breakage. Mascara that contains nylon fibers can give lashes a fuller and longer appearance because it clings to the lashes like mini extensions. Provitamin B5 in mascara acts as a conditioner for lashes, giving them a softer and more natural feel. For safety and health reasons, mascaras should be discarded 3 months after opening.
