Eyelash growth serums are everywhere right now—with promises of longer, fuller lashes in just weeks. But with so many options flooding your feed, it can be hard to know which one is actually worth it.

The truth is, not all lash serums are created equal. Some focus on conditioning, others on actual growth stimulation. So what should you be looking for, and which serum delivers on its claims?

Let’s break it down.

What Makes a Good Eyelash Serum?

A truly effective eyelash growth serum should do more than just coat your lashes. It should:

• Stimulate the lash growth cycle

• Nourish and strengthen existing lashes

• Be safe for daily use around the eyes

• Deliver visible results within 2–4 weeks

Look for active ingredients like:

• Multi-peptides: Encourage lash follicle activity and support the growth phase

• Biotin: Strengthens keratin structures (key for lash durability)

• Panthenol: Moisturises and protects lashes from breakage

How to Use It for Best Results

Apply once daily to clean, dry skin at the base of the lashes (just like you would eyeliner). For brows, apply over sparse areas and let absorb fully. Use consistently every night to see optimal results.
