This brow and lash serum is made of organic NON GMO castor oil, vitamin E oil, coconut oil and avocado oil.  Just apply a little after removing your makeup before bedtime and let it do it's work. It will take a few weeks before you see any noticeable difference. Also if you are using waterproof mascara....it can also affect the health of your lashes because it causes your lashes to dry out and become brittle.
