Start with clean lashes. Place the brush on the lid side of your lashes and gently sweep from the middle of your lashes to the tips each night before bed. To avoid momentary tingling that may occur if product comes into contact with the eye, avoid getting product too close to the lash root. Allow product to dry completely before sleeping. For maximum effect, repeat application in the morning. Allow product to dry completely before applying mascara. Use daily for four weeks. Reduce use to three times per week once you are satisfied with the appearance of your lashes.
