I used GrandeLASH-MD every night for close to a year before I actually read what was in it. I’d checked the box that mattered most to me, cruelty free, PETA certified, no animal testing, and stopped there. That’s the thing about shopping for a cruelty free lash serum: the label answers one question and quietly lets you assume it answered three or four more. The same audit that had already gone through my nail polish drawer, brand by brand eventually reached my lash serum drawer too, and that’s when I found out my go-to pick wasn’t vegan and contained the same hormone-derived ingredient class dermatologists have been raising concerns about for years. I tested nine brands over the following four months to find out which ones were actually clean across the board, not just cruelty free on a technicality. Here’s the honest verdict on each, including the two I couldn’t verify no matter how hard I looked.
What Cruelty Free Lash Serum Actually Means
Cruelty free means a product and its ingredients were never tested on animals, and that the brand doesn’t outsource that testing to a supplier or a third-party lab either. Leaping Bunny and PETA’s Beauty Without Bunnies program are the two certifications that actually carry weight here, since anyone can print a bunny on a bottle without earning it.
Vegan is a separate question entirely. It’s about what’s inside the tube (no honey, no beeswax, no collagen), not whether an animal was harmed to test it. A serum can pass one standard and fail the other, and lash serums are where I’ve seen that trip people up the most.
There’s a third layer specific to this category that most roundups skip: prostaglandin analogues. These are hormone-derived ingredients, isopropyl cloprostenate is the one you’ll see most often, originally developed for glaucoma and repurposed for lash growth because of a side effect. They work, often dramatically. They can also cause eyelid darkening, permanent iris color changes in light-colored eyes, and periorbital fat loss that takes months to reverse, according to one ophthalmologist’s breakdown of prostaglandin-related eye changes. None of that has anything to do with animal testing. A lash serum can be fully cruelty free, PETA certified, and still contain an ingredient your eye doctor would flag. That’s exactly what I found with the first brand on this list.
Every verdict below reflects each brand’s current public stance as of this writing. Certifications and formulas change without much announcement, so if you’re reading this a while after it published, a quick recheck on the brand’s own page or PETA’s database takes thirty seconds and saves you a guess.
1. Grande Cosmetics (GrandeLASH-MD): Cruelty Free, But Not Vegan
Grande Cosmetics is PETA certified cruelty free, and has been for years. That part checks out completely. The brand states plainly that it never tests on animals and that its suppliers don’t either. What surprised me, after nearly a year of nightly use, is that GrandeLASH-MD isn’t vegan (it contains honey as a soothing agent) and it isn’t prostaglandin-free either. The formula includes isopropyl cloprostenate, the same ingredient class discussed above.
I’m not saying don’t buy it. My lashes genuinely looked better within six weeks, and the brand has put the formula through toxicology and safety testing that goes further than most competitors bother with. I’m saying don’t assume cruelty free covers everything you care about, because in this case it doesn’t, and the label never claimed it did. If prostaglandin-free matters to you as much as cruelty free does, keep reading, because most of the rest of this list solves for both.
2. The Ordinary Multi-Peptide Lash and Brow Serum: The Safest Bet
After the GrandeLASH discovery, this was the first thing I switched to, mostly because DECIEM’s cruelty free record is about as clean as this industry gets. Leaping Bunny certified, vegan certified by PETA, and the formula skips prostaglandins entirely in favor of four peptide complexes. It’s also around eleven dollars, which feels almost suspicious given what some other brands on this list charge for a comparable ingredient list.
Here’s the honest trade-off: six weeks in, my lashes looked healthier and shed less, but not dramatically longer the way GrandeLASH had made them look. That’s the peptide-versus-prostaglandin trade nobody puts on the label. You’re choosing gentler for slower, and for my eyes, that trade was worth it.
3. Babe Lash Essential Serum: PETA and Leaping Bunny Certified
Babe Original’s Essential Lash Serum carries both major certifications. PETA lists the brand as cruelty free outright, and the company separately confirms Leaping Bunny status and a vegan formula on its own site. That’s the strongest paper trail on this entire list.
I went through one full tube (about two months of nightly use), and the applicator is genuinely the best of the nine I tried. It’s a fine, precise brush that doesn’t overload the lash line, which matters more than it sounds like it should when you’re applying something this close to your eye every single night. Results were comparable to The Ordinary: gradual and cumulative rather than dramatic, which tracks, since this is another prostaglandin-free, peptide-based formula.
4. Sweed Eyelash Growth Serum: Vegan, Cruelty Free, Prostaglandin-Free
Sweed markets itself directly to makeup artists, and the vegan and cruelty free claims show up consistently across every retailer listing and the brand’s own packaging, not buried in an FAQ somewhere. The formula leans on peptides, biotin, pumpkin seed oil, and vegan keratin instead of anything hormone-derived.
I noticed the texture first. It’s glossier than the others on this list and gives lashes a slight curl and sheen even before any growth results show up, which is a nice bit of instant gratification while you wait the usual four to six weeks for the real effect.
5. Groa Lash Serum: Vegan-First, Self-Verified
Groa doesn’t lean on a bunny logo anywhere I could find, but its own FAQ is direct about it: no animal testing, vegan-friendly formulas, nothing shady in the ingredient list. It’s prostaglandin-free and made with mostly naturally sourced ingredients, dermatologically and ophthalmologically tested.
I’d have liked to see an actual Leaping Bunny or PETA listing to back up the brand’s own statement, and I couldn’t find one, so file this as a brand I believe based on its word rather than one with independent, third-party verification. The serum itself is lightweight and dries fast, which made it easy to layer under my usual nighttime routine without standing around waiting.
6. Glow For It Lash Growth Serum: UK-Made, B-Corp Manufactured
Glow For It is a UK brand manufactured by a B-Corp certified facility, and vegan and cruelty free claims appear consistently across the brand’s site, FAQ, and retailer listings. It’s also explicitly prostaglandin-free, which the brand calls out by name as a selling point rather than something you have to dig for.
I ordered this one specifically because of that transparency, and the ingredient list backs it up: peptides, sodium hyaluronate, and panthenol instead of anything glaucoma-derived. Shipping from the UK took longer than the domestic brands on this list, which is worth knowing if you’re not the patient type.
7. ForChics ForLash Serum: Cruelty Free by the Brand’s Own Word
ForChics answers the cruelty free question directly in its own FAQ: never tested on animals, and no manufacturer it works with tests on animals either. I take that seriously, but I’ll flag the same thing I flagged with Groa: I couldn’t find a PETA or Leaping Bunny listing to independently confirm it, so this is a brand-stated claim, not a certified one. That distinction matters if certification specifically is the dealbreaker for you.
What actually surprised me about ForChics was the price. At around $39 for a three-month supply, it’s one of the more affordable prostaglandin-free options here, and the peptide it uses, myristoyl pentapeptide-17, has at least some published research behind it, which isn’t true of every ingredient on an Amazon lash serum label.
8. Twenty One Beauty Eyelash Serum: Status Unconfirmed
This is the one I have to be straightforward about. I couldn’t find a cruelty free or vegan claim anywhere for Twenty One Beauty’s lash serum: not on the brand’s own site, not on its Amazon listing, not in PETA’s or Leaping Bunny’s databases. That’s not the same as saying it tests on animals. Plenty of small, newer brands simply haven’t gone through certification yet or haven’t published their policy clearly.
But if you’re specifically trying to find out whether Twenty One lash serum is cruelty free because you want a confirmed yes, I don’t have one to give you, and I don’t think anyone writing about this brand honestly does either. It’s prostaglandin-free and peptide-based like most of this list, and it’s built a genuine following through Georgia Harrison’s audience, but the ethical sourcing question is currently unanswered.
9. Epais Eyelash Essential Serum: Also Unconfirmed
Epais ran into the same wall Twenty One Beauty did. No cruelty free or vegan claim on the brand’s own site, on Olive Young, or on YesStyle, and no PETA or Leaping Bunny listing that I could locate.
Worth knowing separately: South Korea has banned cosmetic animal testing on finished products and ingredients since 2017, so the regulatory backdrop here is different from a brand selling into markets like mainland China. That’s context, not confirmation, since a country-level ban doesn’t tell you what one specific brand’s supplier chain looks like today. If you want epais lash serum cruelty free status in writing from the brand itself, I looked and couldn’t find it.
Frequently Asked Questions
Is a cruelty free lash serum as effective as one with prostaglandins?
Usually not as fast, but that doesn’t mean not effective. Peptide-based, prostaglandin-free serums (what most fully vegan and cruelty free options rely on) tend to show gradual improvement over six to eight weeks rather than the more dramatic four-week results some prostaglandin formulas produce. You’re trading speed for a formula that skips the eyelid darkening and fat-loss risk discussed above.
Can a lash serum be cruelty free but not vegan?
Yes, and GrandeLASH-MD on this list is a direct example. Cruelty free is about animal testing. Vegan is about whether animal-derived ingredients, like honey, beeswax, or collagen, end up in the formula. A brand can pass one standard and fail the other, so check both separately if they both matter to you.
How do I verify a lash serum brand is actually cruelty free?
Search the brand name directly in PETA’s Beauty Without Bunnies database or Leaping Bunny’s list of compliant companies. A brand’s own website claiming “cruelty free” is a starting point, not proof, since the term isn’t legally regulated in the US. If neither database lists the brand, that doesn’t automatically mean it tests on animals; it just means you’re relying on the brand’s word instead of independent verification.
Why don’t brands like Epais or Twenty One Beauty confirm cruelty free status?
Sometimes it’s cost. Certification isn’t free, and smaller or newer brands may not have budgeted for it yet. Sometimes the brand just hasn’t prioritized stating a policy clearly on its site. Neither situation is automatically a red flag, but it does mean you’re buying on trust rather than verification until that changes.
Final Thoughts
Nine brands in, the biggest shift in how I shop for this stuff isn’t which logo is on the box. It’s that I now check three things separately: animal testing, ingredients, and what’s actually driving the growth claim. GrandeLASH-MD taught me that the hard way, and I don’t regret the year I spent using it, but I regret not reading past the cruelty free label sooner.
If you want the shortest path to a fully verified, prostaglandin-free pick, The Ordinary or Babe Lash are where I’d start. Both carry real third-party certification and cost less than you’d expect for it. If you’re building out the rest of your routine while you’re at it, it’s worth checking whether your makeup brushes are cruelty free too, since that’s the other overlooked category most people skip entirely.
Whichever one you land on, give it the full six to eight weeks before deciding it’s not working. That’s not marketing spin, it’s just how a lash follicle’s growth cycle actually works, and rushing that judgment is the easiest way to give up on a serum that just needed more time.
