We spent 34 months making this lash serum. Because your eyes deserve better.

It started with a heartbreaking conversation.

Four years ago, one of our co-founders — let’s call her Anna — was sitting in a beauty salon having her lash extensions removed. She looked in the mirror at her bare eyelids and asked her technician a simple question:

“Why do my lashes keep getting shorter every time I take these off?”

The technician paused, then said something Anna has never forgotten:

“Because the glue doesn’t just grip the lashes. It grips the follicles. Over time, they stop growing.”

That evening, Anna went home and put every mascara, lash glue, and half-used “clinically proven” lash serum into a trash bag. That serum had cost her over $60. The packaging promised results in four weeks. After two months, all she had was redness and irritation around her eyes.

This is a problem millions of women share.

We spend thousands on lash extensions. Hundreds on mascaras. Big money on “miracle serums.” But we rarely stop to ask: What exactly am I putting near my eyes?

We asked. And what we found alarmed us.

Many lash serums marketed as beauty products contain a class of ingredients called prostaglandin analogues — compounds originally developed to treat glaucoma. They do make lashes grow longer. But their side effects include:

• Darkening of the skin around the eyes
• Permanent change in iris color (irreversible)
• Loss of orbital fat (causing a sunken eye appearance)
• Persistent redness, stinging, and itching

These risks are documented in pharmaceutical literature. But some brands sell these compounds as “beauty ingredients” — without disclosing the risks.

So we decided to make our own.

In the summer of 2022, Bilberse began. We set three non-negotiable rules:

1. No prostaglandins. No pharmaceutical compounds. Ever.
2. Visible results — or we have no right to ask anyone to buy it.
3. Full ingredient transparency. Every ingredient listed and explained.

What followed was 34 months of development. We tested 17 peptide compounds and went through 9 complete formula iterations. Our fourth formula showed the best results — but our formulator flagged it might cause irritation in 20% of users. We scrapped it. Not because it didn’t work. Because 20% was a number we weren’t willing to accept.

The formula we finally chose.

The core of Bilberse is plant-derived peptides + hyaluronic acid + vitamin B5.

• Plant peptides: Gently signal follicles to extend their natural growth phase — no forcing, no pharmaceutical override.
• Hyaluronic acid: Deeply hydrates the lash line. Dry follicles can’t produce healthy lashes.
• Vitamin B5: Repairs daily damage and strengthens lashes so they’re less prone to breakage.

Think of it less like a drug and more like a nutritious meal for your lashes.

What happened when real people tried it.

We recruited 63 volunteers for a 12-week tracked trial.

• Week 4: 90% reported visibly longer lashes
• Week 8: 87% noticed increased density
• Week 12: 94% said their lashes had never felt healthier

Zero participants reported redness, stinging, or pigmentation changes.

Bilberse launched in 2026.

No celebrity endorsements. No expensive ad campaigns. Our first customers were those 64 volunteers and the friends they told. Since then, Bilberse has reached users in 21 countries.

The thing we’re most proud of isn’t revenue — it’s the messages we receive every month:

“I finally feel confident going out without makeup.”

“My wedding photos show my real lashes. I didn’t need extensions.”

“I don’t have to worry about falsies falling off at the worst moment anymore.”

Every time we read one of those, we think: those 34 months were worth it.

Our promise to you.

• ✅ Full ingredient transparency — ask us anything about what’s in the formula.
• ✅ 30-day no-questions-asked refund — if you don’t see results, we’ll refund you. No hassle.
• ✅ Real support — if anything feels off, contact us and we’ll help.

We didn’t start Bilberse to sell products. We started it so that every woman’s lashes could grow out healthy — and be shown off with confidence.
