GrandeLASH-MD Lash Enhancing Serum by Grande Cosmetics

GrandeLASH by Grande Cosmetics is marketed as an enhancing lash boosting serum that will improve the appearance of eyelashes in as few as four weeks. Grande Cosmetics describes the GrandeLASH serum as an “award-winning lash enhancing serum with a blend of vitamins, peptides, and amino acids to promote the appearance of naturally longer, thicker looking lashes.” Grande Cosmetics also represents that the GrandeLASH serum is “ophthalmologist tested.” The GrandeLASH serum retails for $65 for a three-month supply on It is also sold by major beauty retailers, including,, and

GrandeLASH ingredients include commonly used cosmetics ingredients such as water, amino acids, hyaluronic acid, and vitamin E. However, However, the serum also contains isopropyl cloprostenate, a drug ingredient that the FDA has said is not safe for use except under the supervision of a licensed practitioner.

GrandeLASH Ingredients: Isopropyl Cloprostenate

Isopropyl cloprostenate is one of a class of compounds known as prostaglandin analogs, which are commonly found as active ingredients in drugs used to treat glaucoma. The chemical has the potential to alter the body’s function and structure. Topical isopropyl cloprostenate is associated with side effects such as ocular irritation, ocular inflammation, hyperemia, iris color change, macular edema, lower intraocular pressure, and more.

Despite being FDA-approved for usage in prescription drugs, isopropyl cloprostenate is not approved as a cosmetic additive. Lifetech Resources LLC, which manufactures similar products such as RapidLash, NeuLash, and NeuveauBrow, has received warning letters from the FDA for violating the Federal Food, Drug, and Cosmetic Act after including isopropyl cloprostenate in their products.

Grande Cosmetics allegedly violates federal and state law by using isopropyl cloprostenate in their lash growth products and making certain claims that qualify their products as “drugs” instead of purely cosmetic products. Because Grande Cosmetics does not disclose that GrandeLASH is a drug and does not list possible side effects, Lash Boost is allegedly deceptively marketed and sold.

A GrandeLASH class action lawsuit investigation has been launched into claims that the Grande Cosmetics makes misleading representations that its product is not a drug and that Lash Boost ingredients are not associated with significant side effects, despite the FDA stating otherwise.
