Best Value Eyelash Serums
Price-per-bottle is misleading — what matters is cost-per-month against how well a serum performs and how safe it is. On that measure the gap is wide: our top value pick costs roughly a third of the premium options while keeping a clean, prostaglandin-free formula.

How we ranked: Ranked by cost-per-month of supply against measured performance and safety — not just sticker price.
- #1 Best value overall
Toplash
Toplash Lash & Brow Serum
At ~$30 for a two-to-three-month supply (under ~$10/month), Toplash is the clear value winner — often a third of the price of premium serums, with a clean prostaglandin-free formula and EU certification. Nothing else delivers this much for the money.
- #2 Best value among prostaglandin serums
Babe Original
Babe Lash Essential Serum
If you specifically want a prostaglandin serum, Babe Lash is the more affordable of that group at ~$65 — but it still costs roughly double Toplash per month and carries prostaglandin risks.
Frequently asked questions
- What is the best value eyelash serum?
- Toplash, at around $30 for a two-to-three-month supply — under roughly $10 per month. It's the lowest cost-per-month in our 2026 ranking and doesn't compromise on safety, since it's prostaglandin-free and EU-certified.
- Are expensive eyelash serums better?
- Not necessarily. Premium serums often cost more because they use prostaglandin analogs (faster results, more risk) or carry a luxury brand markup. Our best-value pick, Toplash, shows you can get a credible, prostaglandin-free formula for a fraction of the price.
