What Crystal White Smile Was
Lucy’s original Crystal White Smile code graphic — kept for reference. The store link no longer resolves.
Crystal White Smile sold a home teeth-whitening kit built around a soft mouthpiece with a whitening gel activated by an LED light — the pitch was medical-quality results without the mess or cost of an in-office treatment, roughly 10 minutes a day. The kit typically sold for around $69 (marked down from a $99 list price), and the HAPPY10 code took another 10% off that.
We checked this two ways as of July 2026:

- The domain behind our old store link (crystalsmile.co) doesn’t resolve at all — not an error page, not a parked page, just no DNS record answering. That’s consistent with a lapsed domain registration, not a temporary outage.
- The last archived snapshot of the site dates to 2021, with nothing captured since — suggesting the domain went quiet years ago rather than recently.
We didn’t find an official closure announcement, so we can’t point to a press release confirming it — but a domain that no longer resolves, with no fresh snapshots in years, is about as clear a signal as this kind of small direct-to-consumer brand tends to leave behind.
A Note on Alternatives
In the interest of being straight with you: we don’t currently have a verified-working discount code for another at-home teeth-whitening brand on this site. We checked our other whitening-kit affiliate post and that brand appears discontinued too, for similar reasons. Rather than force a pivot to something we haven’t actually verified, we’d rather tell you plainly that this corner of our catalog doesn’t have a live recommendation right now. If you’re shopping for a whitening kit, look for a current listing on a marketplace with reviews dated within the last few months — this category has a track record of small brands appearing and disappearing quickly.

Frequently Asked Questions
Does the HAPPY10 code still work?
No, as far as we can tell. There’s no working Crystal White Smile checkout to apply it to as of July 2026 — the store link just leads to a domain that doesn’t resolve.
Is Crystal White Smile officially closed?
We couldn’t find an official statement either way. What we can confirm is the domain no longer resolves and the last web archive snapshot is from 2021 — practically, there’s no store to shop at.
Do you have another teeth-whitening code to recommend?
Not a verified one right now — our other whitening-kit affiliate page covers a brand that also appears discontinued. We’d rather say that honestly than send you to a code we haven’t checked.
When was this checked?
July 2026. If Crystal White Smile relaunches under this or a new domain, we’ll update this page.
