The major difference between dry-type strips and traditional gel-type strips is that the white gel on dry-type strips is dry, it has a better resistance to the dissolution of saliva than gel-type strips, and can keep whitening for over 2 hours even more than 6-8 hours which gives the brightener on strips more time to act on the teeth so as to achieve the effect of whitening.
After adopting dry-type design of the gel on strips, the gel can hydrate with saliva on teeth at moment and produce powerful adhesive force which makes it adhere to the teeth tightness so as to stick to the teeth even when doing exercise, speaking and drinking.
During the using process of dry-type strips, the gel will never stick to the fingers and lips, it will be much comfortable and convenient which help to let you whiten at any time any where and bring you a brand new teeth whitening experience.
