Cruelty-free teeth whitening strips are oral care products that are formulated to whiten teeth without being tested on animals or containing any animal-derived ingredients. These strips typically consist of thin, flexible plastic strips coated with a whitening gel containing ingredients such as hydrogen peroxide or carbamide peroxide.

Cruelty-free teeth whitening strips are designed to be applied directly to the teeth and left on for a certain period of time, usually around 30 minutes to an hour, depending on the specific product instructions. During this time, the whitening gel works to break down stains and discoloration on the surface of the teeth, resulting in a brighter, whiter smile.

Many teeth whitening products contain glycerin, — found in “animal and vegetable fats” — propolis, — which is “derived from bees” — or use cruel animal-based testing. This is also not to mention flavors and colorings, which are incredibly hard to verify as vegan unless specifically noted as such. In particular, you want to avoid certain brands that test on animals and/or use animal-derived ingredients “Crest, Colgate, Sensodyne, Arm & Hammer, Aquafresh, Biotene, [and] Spry,” all of which still test on animals. When it comes down to picking up that teeth whitening product, it’s a good idea to go with a cruelty-free, vegan-friendly product.
