The effectiveness and/or hydrating ability of body care compositions, such as moisturizers, skin creams, body lotions, shampoo, hair conditioner, styling gel, styling mist, hair dye, hair perming compositions, bath additives, pedicure and manicure products, facial cleanser, facial mist, suntan lotions, and sunscreen lotions, are enhanced by the addition thereto of an aqueous suspension containing small concentrations of charged colloidal silica particles, preferably of a size between about 10 angstroms and 100 angstroms. With skin care products, the hydrating components are better absorbed into the body epidermal structure. In coloring hair, dye components are absorbed into the hair, and in perming hair, the disulfide bonds in the hair can be broken by tension caused by swelling due to water absorption in the hair, both without the use of damaging alkaline solutions.
