Frequently Asked Questions
Everything you need to know about your numbuzin journey.
How do I choose the right numbuzin number for my skin type?
Each numbuzin product is numbered to target specific skin concerns. We recommend taking our Skin Quiz or checking the product descriptions, which list the primary benefits and suitable skin types for each number.
Are numbuzin products suitable for sensitive skin?
Yes, our formulas are developed with skin health in mind. Many of our products, such as the No.3 and No.4 lines, are specifically tested for skin irritation to ensure they are gentle yet effective for sensitive skin.
How long does shipping take for international orders?
Standard international shipping typically takes 7-14 business days. Please note that delivery times may vary depending on your location and local customs processing.
What is your return policy?
We offer a 30-day return policy for unused and unopened products in their original packaging. If you experience an adverse reaction, please contact our support team with photos for assistance.
Do you offer free shipping?
We provide free standard shipping on all orders over $50. For orders below this amount, a flat shipping fee will be calculated at checkout based on your destination.
Are your products cruelty-free?
numbuzin is committed to ethical beauty. We do not test our finished products or ingredients on animals, and we work closely with suppliers who uphold these same standards.
