There are many products on the market now that claim to lengthen eyelashes. The only one that is FDA approved and is clearly proven to lengthen lashes is Latisse by Allergan. The active ingredient is Latisse is bitamoprost. Bitamoprost was originally used as an eyedrop to treat glaucoma. Doctors noticed that patients that used this glaucoma medication grew long thick eyelashes. Allergan, the makers of Botox, bought the rights to bitamoprost and developed Latisse which is applied to the lash line (like eyeliner) at night. Latisse works great and in my practice my patients see results in as little as 2 to 3 weeks. The main side effect is irritation which can occur in patients who are allergic to the medication. However, most patients tolerate the treatment well and love the results. Latisse is used for 3 months and then is repeated as needed to maintain the eyelash growth.
Some of you may have heard about another ingredient in other eyelash serums called in isopropyl cloprostenate which is an analogue to bitamoprost. However, this ingredient has not undergone the extensive testing that Latisse has done to prove effectiveness. For now, Latisse remains the only treatment that is proven to work. And more research is underway…in my office we are currently investigating to see if Latisse works to regrow lashes in women after chemotherapy. I am looking forward to seeing the end results. I will keep you posted!
