AQUEOUS COMPOSITIONS COMPRISING POLYMER PARTICLES AND LOW LEVELS OF CLAY
The present invention features a composition that includes about 0.75% to about 1.25% by weight of a clay portion that comprises bentonite. The composition includes polymer particles having an average particle size of less than about 20 microns and a refractive index of about 1.3 to about 1.4. The composition is substantially free of hydrophobic compounds. The composition is useful for treating under eye skin.
