Carriers sometimes mark packages as delivered before they arrive, so your package may still show up within 24 hours. If it’s been more than 24 hours, please contact your local carrier with your tracking number.

Once a package is marked as delivered, it’s the carrier’s responsibility, so we’re unable to offer refunds or replacements for packages marked as delivered.

We’re sorry! Please email us at cs_knockus@benow.co.kr within 30 days of delivery with your order number and clear photos of the item, the packaging, and the shipping label. We’ll review your photos and send a replacement or refund. In most cases, you won’t need to send the item back.

For hygiene and safety reasons, we don’t accept returns or exchanges for a change of mind, even if the item is unopened and unused.

Please review your order carefully before checking out. If you’re not sure which product or scent is right for you, email us at cs_knockus@benow.co.kr before you buy and we’ll be happy to help.

Stop using the product right away and consult a doctor if needed. Please also email us at cs_knockus@benow.co.kr with your order number, the product name, the batch number (printed on the packaging), and a brief description of what happened. Every report is shared with our product safety team for review.

Because everyone’s skin reacts differently, we do not offer refunds or returns for skin reactions. To make sure a product is right for you, please check the full ingredient list on each product page and do a patch test before first use.

Once the package is back at our warehouse and inspected, we'll refund the products. The original shipping cost will be deducted, even if your order qualified for free shipping.

Once approved, your refund will be issued to your original payment method within 10 business days. Your bank may take additional time to post it to your account.

For orders placed on Amazon, TikTok Shop or other retailers, please contact that retailer directly. They can help with tracking, returns and payment.
