Measured at one billionth of a meter, nanoparticles are all the rave. Because of their super small size, nanoparticles are able to penetrate more deeply into the skin, transporting ingredients that normally would remain in of the outer layers of the epidermis. However, the nanoparticles' smallness also makes them extremely unstable: their atoms are on the outer surface, which means they readily undergo chemical changes. Even so, according to Linda Katz, director of the FDA's Office of Cosmetics and Colors, cosmetics companies are not required to disclose their use of nanoparticles in their products.
RevitaLift
RevitaLift by L'Oreal is probably the most commonly available moisturizer with nanoparticles. L'Oreal, which also owns Lancome, is the largest patent holder for nanotechnology in the U.S. RevitaLift, according to some who have tried it, is like a "face lift in a bottle." Others have had to discontinue using it because of allergic reactions. RevitaLift may not be recommended for sensitive skin.
