FAQS
FREQUENTLY ASKED QUESTIONS.
Q: How do I use THRIVE® for the best results?
Achieving beautiful, full brows is simple! Ensure your brows are clean and makeup-free. Using the applicator, apply a thin line of serum along your brow once a day, preferably at night. Consistency is key for the best results.
Q: What’s inside this serum? Is it safe?
Our serum is packed with powerful, nourishing ingredients like biotin, panthenol, and peptides, designed to support natural brow growth. It’s free from harsh chemicals and prostaglandins, and fully compliant with the New Zealand Cosmetic Products Group Standard (NZCPGS) 2020. Formulated to be gentle enough for sensitive skin, it’s safe for everyday use. Your brows will love it!
Q: When will I see results?
Patience pays off! Many users see improvements in just 4 weeks, with full results often visible in 4-12 weeks. Everyone's brow journey is unique, so stick with it for the best possible outcome. For a clear comparison, take a photo of your brows before starting, and see the transformation over time.
Q: How does it actually work?
Our serum nourishes and conditions your brows, enhancing their growth and overall health. The carefully selected ingredients, like multi-peptides, vitamin E, and ginseng extract, work synergistically to promote fuller, thicker brows by supporting brow density and strength.
Q: How do I use it?
After cleansing and drying the area, simply apply the serum along your brows once daily. For best results, use it consistently for 4-12 weeks. Remember: a little goes a long way, and consistent use is the key!
Q: Does it contain prostaglandin?
Nope! Unlike many brow serums, our formula is free from prostaglandins and their derivatives, making it a safer alternative for your brows.
Q: Can I wear makeup while using this?
Yes! Apply the serum as part of your skincare routine before makeup. Allow the serum to fully absorb, and then apply makeup as usual.
Q: Is it suitable for all skin types?
Yes! Our brow serum is formulated to be gentle and suitable for all skin types, including sensitive skin. However, we always recommend performing a patch test before the first use to ensure compatibility with your skin.
Q: What happens if I stop using it?
No need to worry, your brows won't thin out if you stop using the serum. For lasting brow health, we recommend incorporating the serum into your beauty routine regularly, just like you would moisturise your face.
Q: How long will a tube last?
With daily use, one tube should last about 4 months. Once you achieve your desired results, you can switch to applying the serum 2-3 times a week to maintain your gorgeous brows.
Q: Are there any precautions?
We recommend performing a patch test before the first use to avoid any adverse reactions. Apply the serum once a day, more frequent application won’t enhance effectiveness and may cause irritation. If you accidentally get the serum in your eyes, rinse immediately and seek medical advice if necessary. External use only. If irritation, redness, or discomfort occurs, discontinue use and consult a healthcare professional. If pregnant, nursing, or undergoing medical treatments, please consult your doctor before use.
