FACTORFIVE Lash/Brow Growth Serum

Fuller, healthier-looking lashes + brows without prostaglandins.

FACTORFIVE Lash/Brow Growth Serum is designed to support fuller, thicker and healthier-looking lashes and browswhile helping condition and strengthen the hair. The formula combines FACTORFIVE’s growth-factor technology with ingredients like biotin, panthenol, caffeine, peptides and basil root extract to support natural-looking lash and brow growth.

It’s also prostaglandin-free, making it one of my favorite options for clients looking for a lash serum without prostaglandin-based ingredients. With consistent use, visible results may be seen in as little as 4–6 weeks.

Why I Recommend It

I love that this isn’t just focused on making lashes look longer—it also helps support the overall health, strength and condition of the lashes and brows.

I personally love using this whenever I use my Plated Eye Serum. It gives me a way to treat the entire eye area: supporting the skin around my eyes with Plated while also giving my lashes and brows a little extra attention.

How to Use

Shake before use. On clean, dry skin, apply a few short strokes directly along the upper lash line and to areas of the brows where you want to encourage fuller-looking growth.

Allow the serum to dry completely before applying your other skincare or beauty products.

For best results, FACTORFIVE recommends using twice daily.

Where It Goes in Your Routine

Apply this to clean skin before your other eye products and allow it to completely dry.

When I’m pairing it with my Plated Eye Serum, I apply the FACTORFIVE Lash/Brow Growth Serum first, let it dry completely, and then apply Plated Eye Serum around the eye area.

Katarina’s Honest Take

This is one of those little additions to my routine that just makes sense. If I’m already putting so much intention into keeping the skin around my eyes healthy and supported, I want to give my lashes and brows that same attention.

I especially love pairing it with Plated Eye Serum for a more complete eye routine—healthy-looking skin, lashes and brows all together.
