The disclosure deals with a lubricative skin engaging member with progressive release of lubricating polymer from a water-insoluble matrix containing thermoplastic elastomer compound and maleic anhydride copolymer and lubricating polymer in concentration less than 30%. The disclosure lies in the use of the maleic anhydride in grafted form on polyethylene and the incorporation of water-soluble lubricating polymer in concentration less than 30% in the thermoplastic elastomer compound, leading to a lubricative mixture, and to a skin engaging member, with increased homogeneity and water absorption ability that assist in the lubricating polymer release in a progressive and controllable manner.

A cosmetic or pharmaceutical composition contains at least one polymer precursor and at least one polymerization catalyst in the presence of which the at least one polymer precursor polymerizes under the action of light. Also, a process for skin tautening, skin fixation and/or wrinkle reduction includes an elastic, wearable polymer layer being formed on the skin when a polymer precursor and a polymerization catalyst are topically applied on the skin area to be treated and the skin area to be treated is subsequently exposed to light.
