Hi, it’s Nima.
One topic I’m asked about most often is the use of prostaglandins in lash serum. Are they safe? Do you need them for results? And what if you’re specifically looking for an eyelash serum without prostaglandin?

So I wanted to take a moment to explain our thinking at UKLASH, clear up a few myths, and share why we made a decision no other brand had made before.

Why UKLASH Offer Three Different Lash Serums

Every lash journey is different. Some people want faster, more dramatic results. Others want a lash serum without prostaglandin, either because of sensitivity, personal preference, or peace of mind. And some want a science-led, long-term approach that focuses on lash strength and health.

That’s why we became the first brand in the world to create three distinct eyelash serums:

• Original Lash Serum - with low levels of prostaglandin analogues
• Sensitive and Complex Peptide Lash Serum - Completely prostaglandin-free eyelash serum options

Not because one approach is “right”, but because choice matters. All of our eyelash serums are dermatologist and ophthalmologist tested, and every formula is designed with safety, transparency, and real results in mind.

Let’s Talk About Prostaglandins

Prostaglandins are known for their ability to extend the growth phase of the lash cycle, which is why they’ve become popular in lash serums. In simple terms, they can help lashes grow longer and fuller more quickly.

However, higher levels of prostaglandin analogues have raised concerns for some users, especially around irritation or sensitivity. I’ve always believed that if we’re going to use prostaglandins in lash serum, it has to be done thoughtfully and responsibly.
That’s why our Original Lash Serum uses low levels of prostaglandin analogues. It’s designed to deliver visible results while prioritising comfort and safety.

This option can be right for you if:

• You want noticeable lash growth sooner
• You’ve used prostaglandin-based serums before without issues
• You’re looking for a balanced, carefully formulated approach
• For Those Wanting a Lash Serum Without Prostaglandin

I also know that many of you actively search for a lash serum without prostaglandin, and that’s something I take very seriously.

This is exactly why we created two prostaglandin-free options, so you never have to choose between results and reassurance.

Our Complex Peptide Lash Serum

This formula is for anyone who loves a science-forward approach. It uses a complex of peptides to support lash strength, density, and resilience over time.
Think of it as training your lashes to be healthier, stronger, and more resistant to breakage. If you’re looking for an eyelash serum without prostaglandin that fits seamlessly into a long-term routine, this one is a favourite.

This one was created with sensitive eyes and skin in mind. It’s gentle, calming, and nourishing, while still supporting natural lash growth.
If you’ve ever struggled with irritation, or you simply want the most minimal, soothing approach possible, this prostaglandin free eyelash serum was made for you.

UKLASH has never been about shortcuts or hype. It’s about giving you honest options, backed by science, testing, and real understanding.
Whether you choose a formula with prostaglandin analogues or an eyelash serum without prostaglandin, what matters most to me is that you feel informed, confident, and supported in your choice.
