Sale details and product claims
The sale runs until 11.59pm on October 12 and includes free two-day delivery on orders over £40.

To use it, shoppers should lightly dampen their toothbrush and dip it into the powder, squeeze regular toothpaste over the top, and brush as normal. The routine should be repeated daily for 14 days, then twice weekly to maintain results, according to the site.

Shopper reviews
The powder has received positive reviews from users. One shopper said: "Ordered this in late November ahead of the Christmas catch-ups. So glad I did! Removed years of tea stains within two weeks. Family members actually commented on how great my teeth looked over dinner."
Another added: "Bought this as a little pre-Christmas treat for myself because my teeth were looking quite dull from drinking red wine. By Christmas Day, my teeth were noticeably brighter and felt super clean, like I'd just left the hygienist."
Some users were more critical. One person on Trustpilot said: "I've only been using the powder for a few days. My teeth feel cleaner. I have not noticed anything else as of yet, but I will continue to use it."
Alternatives and other products
For the whitening strips, which are said to 'lift deep-set stains from coffee, tea, wine, tobacco and ageing', shoppers should peel and apply them in the evening, leave them on for 30 minutes, then peel off and rinse. They can be used daily for 14 days, with seven bonus treatments for top-ups. The strips cost £19.99, down from £39.99.
As an alternative, LookFantastic offers the Spotlight Oral Care Diamond Pap and Powder (15g) for £29.95, with code EXTRA for 20% off. The site describes it as a micro-fine formula that promotes brighter-looking teeth, infused with a stain-lifting ingredient and peroxide. At Boots, the Boots Advanced Teeth Whitening Strips (56 pack) are available for £25, featuring hydroxyapatite for a 'peroxide-free whitening experience that's fast, safe, effective and comfortable to wear'.
Overall, most shoppers were pleased with their purchase. Another commented: "I've purchased the tooth whitening powder twice before my latest order because it works. I wouldn't trust another tooth whitener as I feel confident that my teeth remain protected. The enclosed leaflet gives good instructions on use, delivery was speedy (as always) and price is good value for such a good product."
