A new contender in the crowded at-home teeth whitening market is making waves, not just with bold claims but with published scientific research to back them up. The HeySmile Teeth Whitening Strips, available on Amazon for £19.99, have been shown to improve tooth colour by a significant margin in a head-to-head study.
Scientific Proof of Whitening Power
Independent research conducted by G. Thomas, T. Badrock, and C. Thompson put the HeySmile Whitening Gel to the test against a leading competitor. Using the internationally recognised VITA® Bleachedguide for measurement, the results were clear.
After six applications, the HeySmile formula achieved an average improvement of 10 shades. In contrast, the rival Quick White whitening gel managed an average of only six shades.
The findings, which were reported by the Manchester Evening News, concluded that the HeySmile gel was "effective at whitening the stained enamel samples." For consumers tired of unsubstantiated promises, this evidence-based performance is a major draw.
How the Strips Work and User Reviews
Each pack contains 28 easy-to-apply strips that use an advanced PAP (Phthalimidoperoxycaproic acid) whitening formula. This technology works by oxidising and breaking down stain molecules caused by daily consumption of items like coffee, tea, and red wine.
A key selling point is that the formula is designed to protect enamel and prevent sensitivity, making it a potential option for those who have struggled with discomfort from other whitening treatments. The brand also offers a 30-day money-back guarantee.
On Amazon, the product holds a strong 4 out of 5-star rating. One satisfied customer noted, "After just one use, I noticed my teeth look brighter and cleaner." Another detailed, "I'm really impressed... I noticed a difference after just a few treatments." While most reviews are positive, a small minority felt they had used better products.
Alternatives and Where to Buy
For those considering other options, the market offers several alternatives. MySweetSmile Teeth Whitening Strips are also priced at £19.99 for 21 treatments and use similar 'Advanced PAP Technology'.
Another well-known brand, Crest, offers its 3D Whitestrips Supreme Bright. A pack with seven treatments is currently on sale for £34.99 (reduced from £49.99), with claims to remove years of stains.
The HeySmile Teeth Whitening Strips can be purchased directly from Amazon. With scientific validation, positive user feedback, and a budget-friendly price point, they represent a compelling choice for anyone seeking a brighter smile from the comfort of home.
