Details

Unlock fuller, thicker and healthier looking brows and lashes with our targeted growth serum.

This lightweight, non-greasy 2-in-1 brow and lash growth serum is designed to strengthen and repair brow and lash follicles, reducing breakage over time for visibly fuller, thicker and healthier-looking brows and lashes. Enriched with Acetyl Tetrapeptide-3 and Red Clover Flower Extract, it helps stimulate growth and enhance hair density, making brows and lashes look thicker, longer and more defined.

Hydrolyzed Soy Protein deeply conditions and boosts elasticity, helping to minimize breakage, while supporting stronger, healthier brows and lashes from root to tip. With consistent use, visible improvements can be seen in as little as 6–8 weeks.

FAQS

How long before I see results?
Most users begin to notice visible improvements in length, fullness, and thickness within 6-8 weeks of consistent daily use.
Is this serum suitable for sensitive eyes and skin?
Yes, our Growth Enhancer Serum is dermatologist and ophthalmologist approved and is suitable for sensitive eyes and skin. It is also PEG-free and fragrance-free, making it an ideal choice for those with sensitivities. If irritation occurs, discontinue use and consult a healthcare professional.
Is the serum prostaglandin-free?
Yes, our Growth Enhancer Brow & Lash Serum is completely prostaglandin-free.
How often should I apply it?
For best results, apply the serum once daily, ideally at night, to clean, dry brows and lash lines. Nighttime application allows the serum to fully absorb into the skin for optimal results. However, you can also apply it in the morning before makeup—just allow it to fully absorb (about 2 minutes) before applying makeup or other skincare products. Consistency is key for achieving the best results.
How do I use the Serum with long-wear brow products like Wunderbrow Gel?
If you're using our Wunderbrow Gel , you can still incorporate the growth serum into your routine:

Morning: Apply the Brow & Lash Growth Serum to clean, dry brows and lash lines. Allow it to fully absorb before applying Wunderbrow Gel . This ensures the serum can work effectively without interference from makeup.

Night: It is important to fully remove Wunderbrow Gel from your brows before applying the serum. Cleanse your brows thoroughly using an oil-based cleanser to ensure they are free of product. Then, apply the serum to clean, dry brows as the last step in your nighttime skincare routine and allow it to absorb overnight. The serum must be applied directly to clean skin and hair to deliver optimal results.

Will I lose hair if I stop using it?
No, you won’t lose hair immediately. However, once you stop using the serum, your lashes and brows will gradually return to their natural growth cycle. To maintain fuller, longer results, we recommend continued use.
How long does 1 tube last?
With daily use, one tube typically lasts 8–12 weeks, depending on whether it's applied to both brows and lashes or just one area.
Is it safe to use during pregnancy or breastfeeding?
While our ingredients are gentle, we recommend consulting your doctor or healthcare provider before using any new skincare products during pregnancy or breastfeeding.
Any tips for best results?
Clean Canvas: Always apply to clean, dry skin with no oils or residue.
Consistent Use: Apply once a day, every day. Results depend on routine.
Be Patient: Hair growth takes time. Trust the process - you'll see results with consistent use.

How to Use

Step 1
Use once daily on clean, dry brows and lashes. Apply a thin line (like an eyeliner) along the base of the upper and lower lash lines, from inner to outer corner.
Step 2
Then, brush the applicator through your brow hairs in an upward motion, following your natural brow shape.
Step 3
For best results, apply as the last step in your nighttime skincare routine to maximize absorption.
Step 4
If using in the morning, allow the serum to fully dry before applying makeup.
