Teeth whitening products are widely available, but few are supported by independent scientific evidence. A £19.99 set of HeySmile Teeth Whitening Strips sold on Amazon is now attracting attention after research showed it could significantly improve tooth colour in a short time.
According to a study by G. Thomas, T. Badrock and C. Thompson, the effectiveness of the product was measured using the VITA Bleachedguide, a globally recognised standard for assessing tooth whitening results. The research found that HeySmile Whitening Gel delivered stronger results than a competing product.
After six applications, HeySmile achieved an average improvement of 10 shades on the VITA Bleachedguide, compared with six shades achieved by the rival Quick White whitening gel. The researchers concluded that HeySmile was notably more effective at whitening stained enamel samples.
HeySmile claims users may begin to see visible results after just one application, making it appealing to consumers looking for fast, at-home whitening solutions.
Each box contains 28 whitening strips formulated with PAP technology, which the brand says whitens teeth without damaging enamel or causing sensitivity. This may be particularly attractive to people who have experienced discomfort with other whitening products.
The strips work by oxidising stain molecules caused by common habits such as drinking coffee, tea or red wine. As these molecules break down into lighter components, teeth appear brighter and whiter.
HeySmile also offers a 30-day money-back guarantee. Other at-home whitening options include MySweetSmile Teeth Whitening Strips, priced at £9.99 for 21 treatments, which also use PAP technology.
Another alternative is Crest 3D Whitestrips Supreme Bright, currently reduced from £49.99 to £34.99. The treatment lasts seven days, with strips worn for 60 minutes daily, and claims to remove up to 25 years of stains.
On Amazon, HeySmile Teeth Whitening Strips hold an average rating of four out of five stars. Many reviewers praise their ease of use and lack of sensitivity. One customer said they noticed whiter teeth after only a few applications, while another described them as comfortable and effective.
Some reviewers were less enthusiastic, with one noting they had used better products before. Overall, however, customer feedback has been largely positive, highlighting visible results and convenience.
The HeySmile Teeth Whitening Strips are available to purchase on Amazon.
