The Beautonics eyelash serum is full of vitamins and nutrients to help you obtain fuller, longer lashes. It is super easy to use and won’t drip into your eye or onto your face. I simply brush it onto the base of my eyelashes after my shower in the morning, then go about my regular makeup routine. I apply it again in the evening after removing my makeup. There is no scent, so it won’t bother anyone’s allergies. I can attest to this because I have horrid allergies and this doesn’t bother them at all. I received this product for free in exchange for an unbiased and honest review. Get it here.
