Can be used on sensitive eyes and contact lens wearers as it is tested to assure it will not cause irritation. Lashes are left fuller and thicker. Lashes are also left conditioned and never dried out from use, letting lashes grow. Can be used with La Roche-Posay Toleraine Teint Hydrating Water-Cream Foundation. How to use: apply eye makeup in an upward sweeping motion to lashes, can add more coats if desired.
