Clare Danes reappeared Sunday as CIA agent Carrie Mathison in Showtime series Homeland. Choosing this role was clearly a great career move. Less so her decision to front Latisse, the eyelash growth treatment that uses potentially harmful prostaglandins.

“Latisse has worked extraordinarily well for me,” says Danes. “One friend I recently met up with thought I was wearing false lashes!” It is true that many people report lush results with Latisse. However, many have complained of serious side effects, including impaired vision and change of eye color. See the comments from users on my Latisse post.

The problem with Latisse is that the active ingredient is bimatoprost, a prostaglandin that is a drug used for treating glaucoma. Lashes grow like weeds when they come into contact with this drug. However, there are serious potential side effects including bacterial eye infection, allergic reactions, excess hair growth outside the intended treatment area, and permanent changes in iris and eyelid pigmentation. A couple of years ago, the FDA reprimanded Latisse for not making information about these issues clearer on its website – it now does.

The same prostaglandin drug is in other eyelash enhancers such as Lilash (our readers report side effects and reviews are mixed) and Revitalash. However, we could point Ms. Danes in the direction of several safe and effective brands with our recent Five Best Eyelash and Brow Growth Products.

Claire Danes has also been stubbornly loyal to another product that could easily be bettered, Cetaphil. She’s been telling magazine editors for years that she loves it and recently said to Elle: “My skin is a bit sensitive, so Cetaphil is my standby. “Cetaphil is one of those products celebrities often claim is their go-to (Charlize Theron comes to mind), perhaps to amplify how down to earth they really are. In my view, Cetaphil is a nasty product that does not endear me with sodium lauryl sulfate and no less than three parabens (the other inglorious ingredients are water, cetyl alcohol and propylene glycol).

Ms. Danes also says she uses a ton of  “Kiehl’s and other natural brands.” I grudgingly admire Kiehl’s for  creating a ye-olde-back-of-the-apothecary-all-natural brand when the reality is rather different. L’Oreal-owned Kiehl’s products are far from natural. Take Ultra Facial Cream: it has several silicones, chemicals that impart superficial softness such as Pentaerythrityl Tetraethylhexanoate, a couple of PEGs and several potentially irritating preservatives, including phenoxyethanol and chlorphenesin, which the FDA explicitly advises nursing mothers to avoid. Perhaps the arrival of her new baby will encourage Claire Danes to clean up her beauty act.
