This proprietary formula created by a Harvard dermatologist & Columbia plastic surgeon is designed for optimal eyelash/eyebrow hair growth using only natural, hypoallergenic ingredients that provide a safe and effective solution for those individuals suffering from fragile, thin hairs who want thicker, fuller lashes and brows in a convenient way. Formulated for application to achieve fuller eyebrow and eyelashes. Step 1: Make sure the face is clean and free of excessive eyelid makeup. Also ensure that the eyelashes (and/or eyebrows) are dry before application. Step 2: Remove any excess product from the brush before application. Apply a thin layer of product along the hairs like applying an eyeliner from the inner to the outer corner of the eye just to the upper eyelashes, as it will spread to the lower eyelashes with blinking. Step 3: Allow the product to dry for 90 seconds before applying other products or going to bed. Step 4: Continue to use the product on a daily basis for optimal effect. Size: 5ml (0.17 FL OZ)
