1. Starch-based film technology for truly residue-free application: Utilizing a salivary enzymatic starch film or a penetrating polyacrylate copolymer film-forming agent, the film layer is automatically dissolved by salivary amylase in the mouth after application. No rinsing or cleaning is required after use; the adhesive leaves no residue and does not stick to teeth, completely solving the pain points of traditional whitening strips that leave teeth sticky and require repeated cleaning, thus improving the user experience and safety. 2. High-strength dry-applied technology for anti-slip, anti-dissolution, and non-slip properties: Employing double-sided film dry-applied technology, the gel layer is doubly locked by a protective film and a backing layer, enhancing its resistance to salivary dissolution by 3 times. The high adhesion of the microcrystalline film ensures a long-lasting fit for 1 hour, preventing slippage when speaking or drinking. Say goodbye to the embarrassment of traditional wet strips that easily shift and cause drooling, achieving both freedom of wear and whitening effect. 3. 6%HP Whitening Formula, Targeting Stubborn Yellowing of Teeth. Contains 6% medical-grade hydrogen peroxide + protease complex formula, which precisely penetrates and breaks down extrinsic pigments such as coffee, tea stains, and tobacco stains, improving 2-3 shades in 7 days; the pH value of 6.5-7.5 neutral system is gentle and does not cause tooth sensitivity, and combined with plant whitening factors, it protects the health of tooth enamel and gums while effectively whitening.
