Abstract
The invention relates to a preparation for improving the blood supply. The problem with prior art preparations or processes resides in the fact that soft magnetic components had to be introduced into the body in capsule form or a magnetic field had to be applied after the application of demagnetized particles to the skin. The purpose of the invention is to provide a novel preparation for improving the blood supply in which special hard magnetic particles are used. According to the invention, the preparation for improving the blood supply consists of a pharmaceutically or cosmetically acceptable medium and possibly further additives containing finely distributed hard magnetic single-grade particles with a high coercitive field intensity and grain sizes in the range of 600 to 1200 nm. Dispersions of this preparation exhibit no aggregation of the hard magnetic particles. The preferred use is in the cosmetic and dermatological field.
