90-Day Money-Back Guarantee
We want you to have enough time to experience HAYUNA for yourself. That’s why the HAYUNA Eyelash Growth Serum is covered by our 90-Day Money-Back Guarantee.
How It Works
Try your HAYUNA Eyelash Growth Serum as directed. If you’re not satisfied with your experience, you can contact us within 90 days of receiving your order to request a refund under our guarantee.
To make a claim, email us at hey@hayuna-cosmetics.com with your order number.
Multi-Serum Orders
If you purchased one of our multi-serum offers, one serum may be opened and used as part of your 90-day trial.
Any additional serums from the same order must remain unopened and unused to be eligible for a refund under the guarantee.
For example, if your order contains four serums, you may use one serum to try HAYUNA. The remaining three must remain unopened and unused.
We may ask you to return the unopened products before your refund is processed.
Return Shipping
If products need to be returned as part of a claim under our voluntary 90-Day Money-Back Guarantee, return shipping costs are the responsibility of the customer, unless otherwise required by applicable law.
Please contact us before returning anything. Products returned without prior approval may not be accepted under the guarantee.
Refunds
Once your claim has been reviewed and any required returned products have been received and inspected, we’ll let you know whether your refund has been approved.
Approved refunds will be issued to your original payment method. We aim to process refunds within 10 business days, although your bank or payment provider may take additional time to make the funds available.
Australian Consumer Law
Our 90-Day Money-Back Guarantee is an additional voluntary guarantee and does not replace, restrict or exclude your statutory rights under the Australian Consumer Law.
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.
You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
