We want you to love your smile. If you do not see any visible whitening after following the guarantee process below, we will provide a full refund (subject to these terms).

To qualify for the 100% Money‑Back Guarantee you must complete all of the following:

First Photo (Day 1 window)

Take a full-face selfie showing your teeth and hold the Smiles4Miles product in the same photo.

This photo must be emailed to us at ‘contact@smiles4miles.co.uk’ within 7 days of your order date.

Request Final Code

After we receive your first photo, you must request a final verification code by emailing us. (We will respond with the unique code.)

You must request the code before you submit the second (final) photo.

Second Photo (Final verification)

Within 28 days after we receive your first photo, take a second full-face selfie showing your teeth and holding a piece of paper with the unique code handwritten on it.

Email the second photo to ‘contact@smiles4miles.co.uk’. (This photo is your “after” picture.)

Return the product

After we review the photos, if the refund is approved you must return the product (even if partially used). Returns are sent at your cost. The refund will be issued only after we receive and inspect the returned item.

Timing for a claim

All required photos and the request for the refund must be completed within 35 days of your order date (this allows 7 days for the first photo + up to 28 days for the second).
