How It Works

Three steps. Four to six weeks. Bolder brows.

1

Cleanse

Wash your face and pat brows dry. Skin should be free from makeup, oils, and creams before applying.

2

Apply

Once nightly, brush the serum directly onto your brows — focus on sparse spots and the brow body. One swipe each side.

3

Reveal

Use consistently for 4–6 weeks to fill sparse areas. Continue for fuller, defined arches you didn't know you had.

Real Results

Real customers. Real brows. No filters, no pencil.

Frequently Asked Questions

When will I see results?

Most customers see fuller, denser brows in 4–6 weeks of nightly use. Sparse spots typically fill in by week 8–12. Brow hairs grow more slowly than scalp hair, so consistency is everything.

Can I use it after microblading or brow lamination?

Yes. Wait until any tattooed area is fully healed (typically 2–4 weeks post-procedure) before applying. Many customers actually use the serum to grow real brow hairs underneath their microblading so they can transition off it over time. For brow lamination, apply after the first 24 hours.

Will it work on overplucked or thinning brows?

This is exactly what it's designed for. Botanical extracts wake up dormant follicles — the ones that stopped producing hair after years of plucking, waxing, or threading. Most customers see visible filling in sparse spots starting around week 4.

Is it safe to use with brow tinting or henna?

Yes. Apply the serum at night after your skin is clean. If you tint or henna your brows, do those treatments in the morning or on non-application days. The serum won't strip or alter tint color.

Does it contain prostaglandins or hormones?

No. Many growth serums use prostaglandin analogs that can darken skin and cause irritation. Our formula uses peptides, biotin, and botanical extracts only — safe for the delicate skin around your brows.

Will it irritate sensitive skin?

Our formula is water-based, fragrance-free, and free from harsh actives — designed for sensitive skin. That said, every person is different. If irritation occurs, discontinue use. We recommend patch testing on the inner forearm for 24 hours before first use.

How long does one bottle last?

One 3ml bottle lasts approximately 30 days with daily nightly use. For best results, use consistently for at least 8–12 weeks. Many customers subscribe to keep a fresh bottle on hand.

What if it doesn't work for me?

You're covered by our 60-day money-back guarantee. If you're not seeing results or aren't satisfied for any reason, contact us within 60 days of purchase for a full refund. No complicated returns process.
