Frequently Asked Questions
Everything you need to know about your Numbuzin skincare journey.
How do I know which Numbuzin number is right for my skin?
Our products are numbered based on specific skin concerns rather than steps. We recommend checking our 'Find Your Number' guide or starting with our best-selling No.3 line for skin texture and radiance.
Are Numbuzin products suitable for sensitive skin?
Yes, most of our formulas are dermatologically tested and designed to be gentle. However, we always recommend performing a patch test on a small area before full application.
How long does international shipping take?
Standard international shipping typically takes 7-14 business days depending on your location. You will receive a tracking number via email as soon as your order is dispatched.
What is your return policy?
We accept returns for unopened and unused products within 30 days of delivery. Due to hygiene reasons, we cannot accept returns on products that have been opened or used.
Are your products cruelty-free?
Numbuzin is committed to ethical beauty practices. We do not test our finished products on animals.
Can I use multiple numbered products in the same routine?
Absolutely! You can mix and match numbers to target different concerns. For example, you can use the No.3 Toner with the No.5 Vitamin Serum for both texture and brightening benefits.
