Teeth whitening gel formulated with 18% PAP, a next-generation active ingredient that removes stains without releasing free radicals or damaging enamel. Its peroxide-free formula helps achieve a visibly whiter smile without sensitivity. PAP (phthalimidoperoxycaproic acid) represents a new generation in whitening technology. Unlike peroxide gels found in many at-home cosmetic products, which are limited by regulations to very low concentrations (0.1%), PAP offers a more effective, stable, and safe action. Its use in high concentrations (up to 20%) provides visible results in less time and without damaging tooth enamel. Enriched with mint essential oil, it provides a mild minty flavor and a pleasant feeling of freshness during and after use. Activated by the blue light of the UNICLED WHITE SMILE 5.0 device, this gel enhances its action on stains caused by coffee, wine or tobacco. It can be used as a standalone treatment or as a perfect ally to maintain the effects of professional whitening, with an advanced formula that combines technology, effectiveness and care. The treatment includes 16 single-dose ampoules, designed for 1 month of use, with sessions of only 10 minutes that are easily integrated into the routine.
