The brand is also offering free two-day delivery on orders over £40 and free next-day delivery on orders exceeding £60.
Customer Reviews and Alternative Options
One customer reported: "I started using the whitening powder early in December to get my teeth ready before Christmas parties and family photos. It completely lifted my coffee stains without making my teeth sensitive at all. My smile looked bright and clean for all the holiday photos."
Another commented: "I 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."
One buyer stated on the brand's Trustpilot page, which holds an overall 4.5 out of five 'Excellent' rating: "Great product, makes your teeth smooth. Still waiting to see if it will make my teeth white. I have only used it for a few days. Delivery service was great. Order was easy and it came quickly."
A further reviewer noted: "I've not had long enough to notice a difference yet." However, the vast majority of customers were satisfied, with one user adding: "I ordered this in late November ahead of the Christmas catch-ups. So glad I did! It removed years of tea stains within two weeks. Family members actually commented on how great my teeth looked over dinner."
