Hismile PAP+ Whitening Strips are smart teeth whitening strips that give you whiter teeth in an extremely easy and convenient way. These strips are easily stuck to the teeth in the upper and lower mouth and after 30 minutes you will be able to experience a visibly whiter result. Hismile PAP+ Whitening Strips are developed with an effective, hydrogen peroxide-free PAP+ formula that whitens your teeth but is gentle to both gums and enamel, and does not cause irritation, pain or increased sensitivity. The formula also contains hydroxyapatite and potassium citrate, which strengthens the teeth's protective layer and soothes already sensitive teeth. You can use these Hismile PAP+ Whitening Strips as often as you need. They're ideal for on-the-go so you can achieve a bright, white smile wherever you are. You can also advantageously combine these strips with one of the Hismile V34 products if you want to achieve a maximum, white result.
