Advanced Brow Treatment Duo Set

QUABROW® Advanced Eyebrow Serum Duo Set includes 2 bottles of our advanced, science-developed eyebrow serum created with QUA-X Complex™ — a proprietary brow-conditioning formula that nourishes, strengthens and visibly improves the appearance of natural brows, helping them look fuller, denser, healthier and more defined.

What you can expect

With regular use, your brows become visibly fuller, stronger and healthier-looking — while your face gains a more expressive, balanced and naturally enhanced look.

First visible results can be noticed after 4 weeks, while the fuller effect develops throughout a 12-week treatment routine.

QUABROW® was developed for weak, sparse and over-plucked brows to support their denser, stronger and more defined appearance. After completing the treatment, the serum can be used 2–3 times per week to maintain the effect of more beautiful, expressive brows.

How to Use

How to apply QUABROW® Eyebrow Serum

1. Cleanse your brows

Remove makeup, skincare residue and oils with an oil-free makeup remover or gentle cleanser. Make sure your brows and surrounding skin are clean and dry before application.

2. Apply a thin layer

Apply a small amount of QUABROW® Advanced Eyebrow Serum directly along the natural brow line, focusing on sparse, thin or over-plucked areas.

One dip is usually enough for both brows.

3. Let it absorb

Allow the serum to dry before applying skincare, makeup, brow gel or other brow products.

4. Use once daily for 12 weeks

Apply once a day, preferably in the evening, as part of your daily brow care routine.

Visible results may appear from 4 weeks, while the fuller-looking brow effect develops throughout a 12-week treatment routine.

5. Maintain your results

After completing the 12-week treatment, continue using QUABROW® 2–3 times per week to help maintain the appearance of fuller, healthier-looking and more defined brows.

Top tips

Use on clean, dry brows.
Apply only a thin layer — more serum is not needed.

How to apply Quabrow Serum

Step 01. Start with clean, dry skin. Gently remove all makeup, skincare, or oil-based products from your eyebrow area to avoid forming a barrier between your skin and the serum.
Step 02. Once daily, apply a small amount of QUABROW® directly onto clean, dry brows using the precision applicator. Follow the natural shape of your brows. Allow the serum to fully absorb (approx. 2–3 minutes) before applying any other skincare or makeup.
