Abstract
A skin care product such as a cleansing lotion or pre- or aftershave lotion comprising ethanol, water, spherical polymer or copolymer microspheres, e.g. of polyethylene, polystyrene or polymethylmethacrylate, and a suspending agent for the microspheres. The ethanol:water weight ratio is in the range 1:19 to 19:1 and the microspheres, which may be sized from 5 to 7 microns, amount to 3 to 10% by weight of the product. The microspheres have a smoothing and matting effect on the skin, improving the observed degreasing effect of the product.
