For anyone frustrated by the withdrawal of Jan Marini's eyelash growth product or concerned about the safety of using glaucoma drugs to get longer lashes, keep an eye out for a new product from L'Oreal. It hasn't been launched yet, but L'Oreal was recently granted a patent to develop an organic compound called heterocycle into an eyelash growth product.

In the meantime, six companies, including Marini, Massivelash, MD Lash Factor and Revitalash, are being sued for patent infringement by Allergan. There is still no launch date for Allergan's own eyelash growth product, Lumilash.
