Do Lash Growth Serums Really Work? The 2025 Guide to Longer, Thicker Lashes Naturally
Tired of clumpy mascara, pricey lash extensions, or sparse lashes that never seem to grow? You’re not alone. Searches for “lash growth serum” have surged by 240% in the last year as more people ditch temporary fixes for natural, long-term solutions. But do these serums actually work—or are they just another beauty fad?
In this guide, we’ll break down the science, ingredients, and real-world results of lash serums (including our bestselling No36 Lash Enhancement Serum). Let’s dive in!
How Do Lash Growth Serums Work?
Lash serums are formulated to nourish and strengthen hair follicles at the root. Key ingredients like peptides (e.g., biotinoyl tripeptide-1) send signals to your lash follicles to extend their growth phase, while vitamins (panthenol, vitamin E) and botanicals (green tea extract, castor oil) moisturize and protect lashes from breakage.
Spoiler: They’re not magic—but with consistent use, most serums show visible results in 4–8 weeks.
Top 5 Ingredients to Look For
- Peptides - Stimulate keratin production for stronger, longer lashes.
- Biotin (Vitamin B7) - Strengthens brittle lashes and reduces fallout.
- Hyaluronic Acid - Hydrates follicles to prevent dryness and breakage.
- Castor Oil - A natural emollient rich in fatty acids to boost thickness.
- Panthenol (Provitamin B5) - Conditions lashes for a glossy, healthy appearance.
Pro Tip: Our No36 Lash Serum combines all five powerhouse ingredients in a vegan, cruelty-free formula free of parabens and prostaglandins (a common irritant in cheaper serums).
Do They Really Work? Here’s the Proof
Customers saw longer and thicker lashes after 6 weeks of daily serum use. But results vary based on:
- Formula quality: Avoid serums with harsh chemicals like sulphates.
- Consistency: Apply nightly for 60+ days.
- Lash cycle: Lashes grow in phases—patience is key!
