Mr.blanc, a popular dental beauty brand from the United Kingdom, sells its products in more than 70 countries around the world, and its whitening strips have been proven by clinical trials to achieve an average whiteness of three shades after a complete cycle, so it is also known as "teeth whitening artifact" and is quite popular among young people.

At present, Mr.blanc has two whitening strips, which use the oxidant sodium chlorite as the main ingredient, which is less irritating to the mouth than hydrogen peroxide, and is more gentle to use, suitable for people with sensitive teeth. The regular model in black packaging is a PVP film patch with a trace mint taste to help freshen the breath. The price of a single pair is about 15 yuan, the patch time is 30 minutes, and one box (14 pairs) is a complete cycle, which is a tooth patch product that can achieve long-term whitening in a short time.

The other light blue packaging is an upgraded version, the biggest difference from the regular model is that it is a soluble dental strip, which can dissolve on its own after 15 minutes of use, which is more efficient in terms of ease of use, but it will also bring a more sticky gel feeling to the mouth, and it is recommended to rinse and clean the mouth after use. The upgraded version also uses a box (15 pairs) for a complete cycle, with a unit price of about 15 yuan, and a cycle of about 225 yuan, which is cost-effective, and the whitening effect is slightly better than that of the conventional model, which is suitable for people who pursue no need to tear off the tooth strip after use.
