"Lash Boost is a serum that claims to give you longer looking lashes in four weeks. [...] The lawsuits are basically based on the accusation that Lash Boost contained an ingredient called isopropyl cloprostinate, which poses potentially really harmful risks, that the brand failed to adequately disclose. [...] The plaintiffs argue that the ingredient functions like a drug, working very similarly to prescription lash growth serums, and therefore needs to meet the appropriate FDA regulations, which they say it currently does not. [...] Rodan+Fields was deceptive in its marketing of the product, saying it was a cosmetic, and that the company failed to adequately warn consumers of the potential side effects such as eye irritation, eyelid drooping, and even potentially changing the colors of your iris."

This Viral Eyelash Serum Should Be ILLEGAL?! The Rodan & Fields Lash Boost Lawsuit

"The Rodan + Fields Lash Boost really does work and all the reviews are pretty much good with before and afters looking so good, but with every positive review there was a big caveat. People say how much their eyelashes have grown but my eyes are irritated, followed by how much the product actually damaged their eyes. The product has that all-important prostaglandin analog, and while it works to grow lashes, it comes with really drastic irritation and things that can cause drastic changes to the appearance of your eye other than just your lashes. What's particularly sneaky to me is that the company takes something they know has really drastic results but along with drastic irritation, and yet they sell something like that without being obvious about what these ingredients really can do, whether it's good or bad. The warnings they provide are not good enough—they're just generic warnings you'd find on any cosmetic, but this is an ingredient that's used in drugs and can have a real big adverse effect on people's skin because it's changing the way your skin, the insides of your body, the inside of your skin works. It's not like oh you might get a little bit itchy. This is your eye color might change. These are big differences that should be made crystal clear."

"I found it when I was going through my lipstick drawer at the very bottom, and the thing is like completely dry, the spoolie thing on it. I don't recommend this brand. The price of these is pretty similar to other options, and Rodan+Fields is not my favorite brand because they're an MLM, and MLMs generally are evil unless you're the one at the top. I will never buy this again."

"Rodan and Fields Lash Boost contains prostaglandin analogs which are unregulated over-the-counter versions that are 10 times stronger than prescription Latisse. It causes the same dangerous side effects including dry eyes, redness, permanent eyelid discoloration, iris discoloration, permanent eye color changes, fat atrophy causing sunken eyes, and deepening of the eyelid crease. Women don't realize these are the side effects and don't know what's causing the sinking of the eyes or discoloration, so they don't stop using the product. The side effects start appearing early and can be permanent."

"Rodan and Fields had to pay a huge sum of money, millions or billions, for their lash serum because it had a compound very similar to bimatoprost, a prostaglandin analog. Those prostaglandin analogs can have side effects like discoloration of the eye color, and there are even reports of it changing the distribution of fat around the eyes. They got nailed on that one."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
