Over-the-counter products condition eyelashes. In 2008, LATISSE® became the first and only prescription product FDA approved to grow eyelashes—fuller, longer, and darker—in patients with eyelash hypotrichosis. Eyelash growth is cyclical. The normal eyelash growth cycle involves 4 phases—anagen, catagen, telogen, and exogen—and occurs over several months. LATISSE® is believed to prolong the active growth phase—or anagen phase providing fuller, longer, and darker eyelashes in 16 weeks. Wellspring Skin Care Studio is an authorized retailer of Latisse.
