Is it safe to use Latisse indefinitely?

The short answer to this is yes. You can continue use of Latisse and maintain the benefits. In some cases, Latisse has been associated with dry eye and specifically meibomisn gland dysfunction so if your eyes feel scratchy, sandy or gritty you may need to see your eye care professional.

Hi there and thank you for your inquiry.
There are no studies that suggest Latisse is harmful to eyelashes after prolonged use. Latisse is a great product that can help grow your lashes longer, thicker and darker over the course of several weeks. For maximum effectiveness, Latisse application should be followed by the manufacturer's application guidelines, which is to apply at night to cleansed skin free of makeup or any other skincare products. Once the desired effect has been achieved, Latisse every other night seems to prove satisfactory results in maintaining the lash lengthening effects.
