FEATURED INGREDIENTS & BENEFITS
?? Dimethyl Urea (DMU): Keratin cross-linker that increases nail strength. Safer alternative than formaldehyde, as it does not cause allergic reactions and will not excessively cross-link the keratin, which can lead to nail brittleness.
?? Polyvinyl Butyral, Nitrocellulose: Film formers used in nail treatments and Colour.
?? Tosylamide/Epoxy Resin: Provides a protective, flexible coating and promotes adhesion. This is the premier resin of choice for high-quality, professional nail Colour products.
?? Benzophenone-1: UV light absorber that prevents discoloring or fading.
?? CND Toughen Up base coat is 3-free.
?? Regulatory agencies in some areas have begun to restrict or ban the use of Formaldehyde, Toluene and Dibutyl Phthalate in cosmetic products.
