Definitions

  • the invention relates to an electrical cosmetic device for improving the skin tone, according to the preamble of claim 1.
  • Such devices have been known in the trade for professional use in cosmetic studios for many decades. They work with two rod-shaped electrodes which are held in one hand by the beautician when the device is in use and, if necessary with the interposition of a contact agent, placed on the customer's skin at desired locations. As a result, the circuit between the electrodes is closed over the customer's body and a current flows. The current in the customer's body is generated in accordance with the impulse applied to the electrodes and can be either pulsating or alternating direct current.
  • direct current also of alternating direct current
  • This effect may sometimes be advantageous in the case of targeted use, but also applies to impurities or the like which are already present on the customer's skin in an uncontrolled manner and whose incorporation is harmful.
  • even lower current intensities, such as are required to achieve noticeable effects lead to one piercing sensation of every impulse. Increasing the current to intensify the effect is often rejected as painful.
  • the object of the invention is to provide an electric cosmetic device according to the preamble of claim 1, which is suitable for self-use in household use and enables largely pain-free intensive treatment.
  • the combination of the electrodes in pairs in a treatment head enables simple one-hand self-treatment, in which the treatment head is guided over the skin in the desired manner.
  • the voltage differences, as well as electrical fields, act flat on the skin in the area of the treatment head and thus produce a complex, superimposed action.
  • a voltage drop lies both to the opposite electrode of the pair of electrodes and to one or more others Electrodes of the opposite polarity of another pair of electrodes, so that complex current paths result in a large area effect on entire skin areas.
  • the provision of the pulse frequency on the basis of modulation of an alternating current carrier wave ensures that galvanic forces in the same direction are only present for very short periods of time, which do not allow electrically charged impurities to migrate into the skin.
  • the higher-frequency alternating-current carrier wave leads, irrespective of the pulse frequency, to stimulation of the skin and the underlying tissue layers in such a way that even when using relatively high current strengths for cosmetic use, there is no stinging sensation.
  • the alternating current carrier wave leads to an electrical massage-like effect on the underlying tissue and thus promotes detoxification; this is further supported by mechanical action from the treatment head or from its electrodes.
  • the electrodes according to claim 2 have spherical spherical contact areas on the skin, this enables pressing on the skin surface with any desired intensity and low-resistance sliding and thus further supports the mechanical massage effect.
  • the treatment head according to claim 3 is provided with a handle part arranged transversely to the axis of symmetry of the treatment head, reaching and desired massage action on hard-to-access parts of the body is facilitated even in the case of self-treatment.

Abstract

Un instrument cosmétique électrique pour l'amélioration du tonus de l'épiderme produit des impulsions de tension qui sont appliquées à l'épiderme d'un utilisateur par l'intermédiaire d'une tête de traitement (8) pourvue de quatre électrodes (13), provoquent un courant inférieur à 20 mA et amènent une amélioration du drainage lymphatique et de la circulation sanguine dans la zone corporelle traitée. Un générateur d'impulsions module une onde porteuse à courant alternatif haute-fréquence et produit des impulsions de courant alternatif sélectionnables carrées ou en triangulaires, véhiculées vers la tête de traitement (8) par l'intermédiaire d'un câble de liaison (2), à l'intérieur d'une plage de fréquence de 5 à 100 Hz.
