The key to growing your new, long, lovely lashes is not only in the bottle, but in the application! Everyone seems to have a different way of applying this product but this is the way that I find is the easiest without wasting product, or worse, over applying product which just increases the chances of hyperpigmentation and does not help your lashes grow any faster. Dont drop the solution into your eye (may cause dry eye). One drop on eyeliner brush per eye. Dont use more than once a day. Use only only clean skin.
