HD Powders incorporate the flexibility and performance of a homopolymer while maintaining application control of a copolymer. These patent pending Smart Polymers™ and Optical Brighteners are time released through encapsulated Microspheres. The Plasticizers continue to strengthen the HD nail during the life of the enhancement. Optical Brighteners use a blue colorant that eliminates any discoloration. Whites look whiter, pinks pinker and clears are clearer with the additional benefit of UV Protection.
