Shipping & Returns
How much is shipping?
We offer free shipping on all orders over US$80. For orders below this amount, a flat shipping fee will be applied at checkout based on your delivery region.
How long does delivery take?
Delivery times vary by region. Most international orders arrive within 7–14 business days after dispatch. You will receive a tracking number via email once your order has been shipped.
What is your return policy?
We accept returns within 14 days of delivery for unopened, unused products in their original packaging. As skincare products are subject to hygiene standards, opened items cannot be returned unless they are defective. Please contact us at support@kohonjin.com to initiate a return.
Products & Rewards
How do I earn points?
You earn points with every qualifying purchase, as well as through actions like writing a review, following us on Instagram, and signing up as a new member. Points can be redeemed at checkout — every 100 points equals US$1 in store credit.
How do I qualify for VIP Membership?
VIP Membership is automatically granted when your annual purchase amount reaches US$800 or your accumulated points reach 80,000P. VIP members enjoy complimentary shipping, exclusive gifts, early access to new product launches, and more.
Can I use my points and a discount code together?
At this time, points and discount codes cannot be combined in a single transaction. We recommend choosing whichever option offers the greater value for your order.
