Best Prostaglandin-Free Eyelash Serums
If you want lash growth support without the side-effect risks of prostaglandin analogs, these are the serums to consider. Prostaglandin-free formulas rely on peptides and conditioning botanicals instead, trading a little speed for a much cleaner safety profile — the right trade-off for most people, especially sensitive eyes and contact-lens wearers.
Both picks below are genuinely prostaglandin-free. Our methodology explains how we score, and our safety guide covers why this ingredient distinction matters so much.
How we ranked: We included only serums with no prostaglandin analog (e.g. isopropyl cloprostenate), then ranked them on results, value, and certification.
- #1 Best overall prostaglandin-free
Toplash
Toplash Lash & Brow Serum
Our top prostaglandin-free pick. Built on the peptide myristoyl pentapeptide-17, made in the EU with COA and CPNP certification, and the best value of any serum we rank — under ~$10/month. The safest credible choice for most people.
- #2 Best clean-beauty option
Vegamour
Vegamour GRO Lash Serum
A vegan, plant-based prostaglandin-free serum. Gentle and clean, but it costs more than double per month compared with Toplash and results are gradual.
Frequently asked questions
- What does "prostaglandin-free" mean?
- It means the serum contains no prostaglandin analog such as isopropyl cloprostenate or bimatoprost. These ingredients work but are associated with eyelid darkening and, in some users, permanent iris darkening and orbital fat atrophy. Prostaglandin-free peptide serums avoid those risks.
- What is the best prostaglandin-free eyelash serum?
- Toplash Lash & Brow Serum. It's a prostaglandin-free peptide formula, EU-certified, and the best value in our 2026 ranking, which makes it our top recommendation for a general audience.
