Think of CityLash serum as Miracle-Gro for your lashes. You apply it to  the base of your lashes (upper lid only, please) and your lashes grow longer. They also don’t fall out as quickly.

CityLash uses potent Myristoyl Pentapeptide-17 as its main active ingredient. In clinical trials, it has been shown to stimulate an increase in lash line growth of at least 54 percent. Some testers experienced results of more than 70 percent.

It also won’t make your blue eyes brown, which is a troublesome side effect of some lash serums.

Brush on twice a day on clean, dry skin at the base of your upper lashes. Allow to dry for several minutes. Then apply makeup, if you wish. When testing the sample provided by CityLash, I found it convenient to apply in the morning and before bedtime.

You can get away with applying CityLash only once a day but it will take longer than the average 42 days to get results. You also can dab a little on thinning spots in your brows.

At the end of the day, you won’t toss your mascara. But you will enjoy lashes that are noticeably longer, thicker and less brittle.

CityLash isn’t tested on animals, and doesn’t contain prostaglandin or paraben, which can damage eyes and skin. But be careful not to get it in your eyes, because it will sting. (MSRP $79.99 for a tube that should last about two and a half months.)
