Abstract

The invention relates to a cosmetic for assisting the transport of oxygen in the skin, a process for its preparation and the use thereof. The problem with the known cosmetics is the inadequate oxygen supply to the skin and the adjoining tissue. The object of the invention is therefore to get through the horny layer of the skin and the epidermis by penetration processes in order to increase the oxygen concentration in the dermal area and adjoining tissue and to activate metabolic processes. According to the invention, this is effected by a cosmetic containing asymmetric lamellar aggregates, consisting of phospholipids and oxygen-laden fluorocarbon or fluorocarbon mixture, the amount of fluorocarbon being in the range from 0.2 to 100% weight/volume, in a carrier suitable for dermatological use. Preparation is effected by emulsification of the corresponding constituents, and use in ointments, creams, lotions, waters, alcoholic extracts, pastes, powders, gels, tinctures or on dressings and plasters or in a spray.
