Why Your Last Serum Didn't Work
It probably wasn't your lashes. It was one specific ingredient.
The Ingredient
Most well-known lash serums (including some of the biggest names) use a class of ingredient called prostaglandin analogs. It's the same drug class behind Latisse, and it works by forcing the eye area into an inflammatory growth response. That's part of why it can deliver dramatic results, and part of why it's also the ingredient most linked to stinging, redness, and in a 2022 class-action settlement against Rodan + Fields, allegations of eye-color changes.

The Alternative
Zyrelle doesn't use prostaglandins. Instead, it's built on signal peptides, ingredients that work with your lash follicles, telling them to upregulate keratin production during their natural growth phase, rather than forcing a reaction to fake the same result. No inflammatory response. No stinging. Just a formula that works with the cycle your lashes already have.
Peptide-Powered, Prostaglandin-Free
A signal-peptide serum that works with your lashes' natural growth cycle, not a drug-class ingredient that forces one.
Myristoyl Pentapeptide-4
Eyelash signal peptide that upregulates keratin production and increases lash length, thickness and density.
Biotin + Panax Ginseng
Helps enzymes involved in protein metabolism, which indirectly supports keratin production in hair and lashes.
Acetyl Hexapeptide-8
Rejuvenates, strengthens and conditions the hair follicles, contributing to fuller-looking lashes and brows.
Palmitoyl Tripeptide-1
Collagen and keratin-signalling peptide that supports stronger lashes and improves hair fibre resilience.
How We Compare
Safer than other serums. More affordable than extensions. Built for your natural lash cycle.

Actually worth the wait
“I was skeptical because I’ve tried several lash serums that did absolutely nothing, but Zyrelle surprised me. Around week 8 I started noticing a real difference.”

Very happy with the results
“It definitely took patience, but by about two months my lashes looked fuller than they had in years. I especially appreciate that it feels gentle compared with serums I’ve tried before.”

So much better than extensions
“Between the appointments, refills and cost, I was completely over lash extensions. Zyrelle takes a little longer to see results, but I love having my own lashes back and not worrying about another appointment.”

Frequently Asked Questions About Our Eyelash Serum
You got questions. We got answers.
Is this safe for my eyes long term?
Yes. Zyrelle doesn't contain prostaglandin analogs (the ingredient class linked to eye-color changes, irritation, and the risks reported in other lash serums). It works by signaling your existing follicles rather than forcing an inflammatory growth response, so there's no drug-class risk building up with continued use.
Will my lashes fall out again if I stop using it?
Like most lash and hair treatments, results are maintained through consistent use. We recommend continuing your daily routine to support ongoing growth (the same way you would with any lash or skin care habit), but there's no rebound shedding or "cliff" the way there can be with some prostaglandin-based products.
Is this actually different from the serum that irritated me before?
Almost certainly, yes. If your last serum stung or caused redness, it very likely contained a prostaglandin analog, the ingredient class responsible for that reaction. Zyrelle is built on signal peptides instead, which work with your natural lash cycle rather than forcing a response, which is why most customers report no stinging or irritation at all.
Is the serum safe during pregnancy or breastfeeding?
We recommend checking with your doctor before using any new product during pregnancy or while breastfeeding.
Can I use this lash serum if I wear eyelash extensions?
Yes. Apply it along the lash line, avoiding direct contact with the extension bonds.
Can I use it with mascara?
Yes. Apply the serum to clean, dry lashes at night and let it absorb fully. Mascara can go on as normal the next morning.
Are you cruelty free?
Yes. We never test on animals, and neither do our suppliers.
How long does shipping take?
Orders are dispatched within 1-3 business days. Delivery times depend on your location and the option chosen at checkout.
Ready for lashes you don't need mascara for?
One daily swipe. Visible results in 8-12 weeks, or your money back.
