30-day money-back guarantee
Try it for a full 30 days. If you don't see fuller, healthier brows, you'll get your money back.
Most brow serums only condition the hair. Ours delivers biotin, peptides and castor oil to the follicle itself, so new hairs grow thicker and stay longer.
Formulated for thinning, over-tweezed and mature brows. Works on all hair colours and skin types, including sensitive skin.
Once nightly on clean, dry brows. Sweep the applicator along the brow in the direction of growth. Results start around week 4; full results at 12 weeks.
Use it for up to 30 days. Not seeing results? Email support@relumebeauty.com with your order number for a full refund.
Key actives: Biotin, Myristoyl Pentapeptide-17, Castor Seed Oil, Panthenol, Hyaluronic Acid. Full ingredient list printed on the packaging. Fragrance-free and hormone-free.

Loved by thousands
After 40 years of over-plucking I thought they were gone for good. Six weeks in and I have actual hairs where there was nothing.

The ends of my brows had thinned to nothing after menopause. Now they reach past the corner of my eye again. Honestly shocked.

I have rosacea and everything stings. This one doesn't. I use it every night and my brows look thicker and darker.
Verified purchase
I'd tried two other serums that did nothing. By week five my daughter asked if I'd had microblading.
Verified purchase
Lost my brows during treatment. My oncologist said it was safe to try. Three months later they're fuller than before.

One swipe at night, that's it. My brow gel now has something to hold onto.

Brows that
Years of tweezing, waxing and hormonal changes shrink the brow follicle until hairs grow in finer or stop altogether. Our serum feeds that follicle nightly with biotin and growth peptides so it produces thicker, stronger hairs again.
New growth is visible around week 4, with full results by week 12 of nightly use.
Panthenol and castor oil coat existing hairs so fewer fall out between cycles.
One swipe
The precision applicator lays down exactly the right amount. Sweep along clean brows, let it absorb for 60 seconds, and sleep. No sticky residue, no scent, no makeup interference in the morning.
Hormone-free, fragrance-free and ophthalmologist tested. No prostaglandins.
Myristoyl Pentapeptide-17 shown to increase hair thickness and density in independent studies.
