Preparation for improving the blood supply containing hard magnetic particles

摘要

A preparation for stimulating the blood circulation of the skin comprising a dispersion containing a proportion of finely divided magnetically hard single-domain particles in the dispersion being in the range from 0.01% to 70% by weight, based on the total weight of the dispersion; these particles having a strong coercive field and being in the range 600 to 1200 nm; and the magnetically hard single-domain particles are selected from the group consisting of barium hexaferrite, strontium hexaferrite, undoped barium hexaferrite, undoped strontium hexaferrite, and the mixtures thereof; and the balance up to 100% by weight of a cosmetic or pharmaceutical excipient carrier substance or a pharmaceutical additive, based on the total weight of the dispersion.
