The Babe Lash Eyelash Serum class action settlement resulted in a $2.3 million payout by Elixir Cosmetics OPCO, LLC over undisclosed side effects from their popular lash-growth products. The case, Skarpnes v. Elixir Cosmetics OPCO, LLC, centered on the company’s failure to adequately warn consumers that the serums could cause iris discoloration—permanent changes to eye color—along with darkening of the eyelid area and permanent dark circles.
If you purchased Babe Lash Essential Lash Serum, Babe Lash Eyelash Serum, Babe Amplifying Brow Serum, or Babe Brow Serum between June 1, 2019 and January 19, 2024, you may be eligible to claim compensation without needing to prove you experienced side effects. The settlement addresses a critical gap between what consumers expected from these products and what they were warned about. The active ingredient responsible for these effects—isopropyl cloprostenate, a prostaglandin analog—can penetrate into the eye and cause pigmentation changes, yet the original labeling did not adequately disclose this risk. California courts initially blocked the settlement in July 2024, specifically citing insufficient warnings about potential side effects, forcing Elixir Cosmetics to revise their product labeling and warnings before the settlement could move forward.

What Side Effects Did Babe Lash Fail to Warn Consumers About?
The primary undisclosed side effect from Babe Lash serums is iris discoloration—a permanent darkening or change in eye color that can occur in people with lighter-colored eyes. This happens because the active ingredient, isopropyl cloprostenate, stimulates melanin production in the iris tissue itself. Unlike a temporary stain that washes away, iris discoloration is irreversible; once your eye color darkens, it remains changed permanently. A woman who purchased the product expecting longer lashes but ended up with darker brown eyes instead of her original hazel color exemplifies the type of unexpected harm the lawsuit addressed.
Beyond eye color changes, consumers reported permanent dark circles developing beneath the eyes and persistent darkening of the skin at or around the lash line. These effects result from the same mechanism—melanin stimulation in areas the serum contacts. The company’s original warning labels mentioned eye irritation and redness but made no mention of discoloration risks, which is particularly problematic because these effects are not reversible like typical cosmetic side effects. A consumer could stop using the product, but the darkened skin and changed eye color would persist indefinitely.

How Did the Failure to Warn Become a Legal Problem?
Cosmetic companies are required to disclose known or reasonably foreseeable side effects of their products. The active ingredient in Babe Lash serums—isopropyl cloprostenate—is derived from prostaglandin analogs, a class of compounds well-documented in medical literature for causing iris discoloration when used in ophthalmic products. This ingredient had been studied in prescription eye medications where the discoloration risk was clearly disclosed. When Elixir Cosmetics used this same ingredient in over-the-counter beauty serums, they failed to include comparable warnings about pigmentation changes.
The failure to warn claim became stronger because consumers had no reasonable way to know about the discoloration risk. Unlike an ingredient known to cause stinging or mild irritation, iris discoloration can develop gradually over weeks or months of product use, making it difficult for consumers to connect the effect to the serum after purchase. By the time someone noticed their eye color had changed, they had already applied the product many times and potentially caused irreversible harm. The lawsuit argued that Elixir Cosmetics knew or should have known about this risk and had an obligation to disclose it before consumers bought the products.
Who Is Eligible for Compensation Under This Settlement?
You are eligible if you purchased any of the four affected Babe Lash products between June 1, 2019 and January 19, 2024. The products covered include Babe Lash Essential Lash Serum, Babe Lash Eyelash Serum, Babe Amplifying Brow Serum, and Babe Brow Serum. There is no requirement to prove you experienced side effects—the settlement compensates all purchasers during the eligibility window regardless of whether they suffered iris discoloration, dark circles, or skin darkening. This is important because many consumers may have used the product without noticing or attributing visible changes to the serum.
Compensation amounts depend on whether you have proof of purchase. If you kept your receipt, product packaging, or have a credit card statement showing the purchase, you can claim $25 per unit purchased. Without proof of purchase, you can claim $25 per household, meaning one payment per address even if multiple people in that household bought the product. For example, a person who purchased three different Babe Lash products during the eligibility period can claim $75 with proof of all three purchases, but only $25 maximum if they cannot provide documentation. The claims process typically requires completing an online form or submitting documentation through the settlement website.

How Do You File a Claim and Receive Your Settlement Payment?
Filing a claim in the Babe Lash settlement is straightforward and available at the official settlement website, blsettlement.com. You will need to provide your name, contact information, and details about your purchase—the specific product name, quantity purchased if possible, and approximate purchase date. If you have proof of purchase, upload a photo or document showing the transaction. If you do not have proof, you can still file; the settlement allows claims without documentation, though the per-household limit of $25 applies in those cases.
After submitting your claim, the settlement administrator processes requests and pays out approved claims by check or electronic transfer, depending on the option you select. The timeline for payment varies—some claims are processed within weeks while others may take several months, particularly if documentation is requested or needs verification. A critical limitation to understand: this settlement is not an insurance claim that covers ongoing treatment for side effects. The $25 to $75 payment is a one-time compensation for the product purchase itself and the failure to warn, not reimbursement for dermatological treatment if you developed permanent discoloration.
What Changes Did Elixir Cosmetics Have to Make to the Products?
As part of the settlement, Elixir Cosmetics was required to update product labeling, ingredient disclosures, and advertising with more detailed cautionary information about potential side effects. This includes prominent warnings about the risk of iris discoloration, particularly for people with lighter-colored eyes, and warnings about the possibility of permanent dark circles and skin darkening around the lash line. The updated warnings must now appear on product packaging, ingredient lists, and in any online product descriptions or marketing materials. However, the warning requirement does not mean the products were pulled from shelves or reformulated.
Elixir Cosmetics can continue selling Babe Lash serums—they just must include the new warnings that were previously absent. This distinction is important: the settlement addresses the company’s failure to inform consumers, not a determination that the product is unsafe for all users. Some people will use the serum and never experience side effects, while others may develop iris discoloration even with the warnings in place. The settlement essentially says that consumers have the right to know about this risk before they choose to buy.

Understanding the Legal Timeline and Court’s Initial Rejection
In July 2024, the California district court initially denied the settlement’s final approval, specifically citing the settlement’s insufficient warnings about potential side effects. The judge determined that the original warning language did not adequately communicate the seriousness and permanence of iris discoloration and other pigmentation changes. This rejection forced the settlement back to negotiation—a relatively rare occurrence that underscores how seriously courts take consumer protection in failure-to-warn cases.
After the July 2024 denial, Elixir Cosmetics and the settling parties amended the settlement agreement to include expanded and clearer warnings about all disclosed side effects. Following these revisions, a final approval hearing was scheduled for January 2025. This process demonstrates that even when a company and plaintiffs agree to settle, courts will scrutinize whether the settlement truly protects consumer interests and communicates material risks accurately. The delay added several months to the timeline for payments, but it resulted in more comprehensive warnings on the products.
Prostaglandin Analogs in Cosmetics and What Consumers Should Know
Isopropyl cloprostenate belongs to a class of compounds called prostaglandin analogs, which are widely used in prescription eye medications for glaucoma treatment. In those medical contexts, iris discoloration is a known and disclosed side effect, but it is accepted because the medication treats a serious eye disease. When the same ingredient appears in cosmetic products intended purely for eyelash growth, the risk-benefit calculation changes—consumers are accepting a risk of permanent eye color change for cosmetic enhancement rather than medical necessity.
This case highlights a broader issue in the cosmetics industry: ingredients borrowed from pharmaceutical applications may carry undisclosed risks when repurposed in beauty products. Consumers should be cautious about any eyelash or eyebrow serum claiming dramatic growth results, as these effects often come from prostaglandin analogs or similar compounds with documented side effects. Reading ingredient lists and researching active ingredients before purchase is now more important than ever, especially for products applied near the eyes where systemic absorption can occur.
