Customer/Our Review: Most all other bleaches use different blends and additives to make the gel less expensive as the base which causes prolonged quality. These syringes contain only pure blends glycerin base (which causes fastest dramatic results ), no added fluorides (which slows down the whitening process). This product is stronger than the other whiteners. This is our customer's preferred overall professional whitening gel.
