The layering formula allows you to create natural or dramatic looks depending on the number of layers. Applying the mascara to another mascara will make it waterproof. Additionally, the patented brush wraps and separates lashes one at a time for an impact area. Suitable for contact lens wearers, ophthalmologically tested.
