I am 75 years old and have tried Latisse (you can only get it from a dermatologist and it is way more than Nulastin!) and other eyelash growth products but I decided to give Nulastin a chance and even though it took about four weeks to start seeing results I am still on my first bottle and my eyelashes are amazing! My eyebrows have always been fine but not my eyelashes and now others ask me "what have you done to get your eyelashes to grow like that!" I will continue to use Nulastin and will also give it as gifts to family and dear friends.
