I searched the net for a natural eyelash/eyebrow serum for quite a while before finding this. I am very happy with the price and ingredients, but a little unhappy with the product itself. The shipping was speedy and I was excited to use my new product but after three tries on my lashes, I was forced to admit it was indeed irritating my eyes and making them water and smart. I will use this on my eyebrows instead but I'm not sure I'll reorder as I'd like a product I can use on my lashes and brows both.
