Isopropyl Cloprostenate Blamed for Lash Boost Side Effects

Rodan and Fields denies Lash Boost includes any drugs, but the FDA says isopropyl cloprostenate is only appropriate for use in medications used to treat patients who are monitored by a licensed physician.

Isopropyl cloprostenate is a synthetic prostaglandin analog that works by lowering the intraocular pressure in glaucoma patients. Several years ago, glaucoma patients treated with medications that included isopropyl cloprostenate noticed a side effect was that their eyelashes grew longer and more lush. The positive aspects of that side effect weren’t lost on the cosmetics industry.

Lash Boost is a popular lash-enhancing serum because today’s beauty standards often focus on long, lush eyelashes. While some women opt to use mascara or have semi-permanent lashes applied, others wish to enhance their own lashes.

Many companies promote lash-boosting products that leave lashes shinier or more supple, but Lash Boost is marketed to improve the length and volume of lashes in four weeks. Rodan and Fields sells a vial of Lash Boost for $150 on the company’s website, which also warns users that “some people may experience a mild tingling sensation after application. It should improve within a few minutes and disappear completely with continued use. Stop using if tingling, irritation and/or redness persist.”

Other cosmetics companies have received warning letters from the FDA for violations of the Federal Food, Drug and Cosmetic Act. RapidLash Eyelash Renewal Serum, NeuLash Active Eyelash Technology and NeuveauBrow Active Eyebrow Technology all contained isopropyl cloprostenate.

The FDA determined the products were drugs because they were applied in order to affect a change in the body, which in this case was inducing eyelash and eyebrow growth.

In addition to lowered intraocular pressure, other side effects can include ocular irritation, iris color change, darkened eyelid skin, macular edema, eye inflammation and hyperemia, which is an excess of blood going to the eyes. Other side effects can include sunken eyes because the fat area around the eye socket shrinks with regular use of certain glaucoma medications.

Lash Boost contains other ingredients that most likely condition lashes. Water, keratin, glycerin, panthenol and lecithin are common moisturizing ingredients in cosmetics and are found in Lash Boost. The inclusion of isopropyl cloprostenate changes the categorization of Lash Boost from a cosmetic serum to a drug.
