“It’s an invisible layer that can provide a barrier, provide cosmetic improvement, and potentially deliver a drug locally to the area that’s being treated,” said Daniel Anderson, from Massachu-setts Institute of Technol-ogy (MIT)..In tests with human subjects, the researchers found that the material was able to reshape “eye bags” under the lower eyelids and also enhance skin hydration. The researchers then tested the materials in search of one that would best mimic the appearance, strength, and elasticity of healthy skin.The material, a silicone-based polymer that may be applied on the skin as a thin, imperceptible coating, mimics the mechanical and elastic properties of healthy, youthful skin. This impairs skin’s ability to protect against extreme temperatures, toxins, microorganisms, radiation, and injury.The researchers, including Alpesh Patel, formerly at US-based beauty company Living Proof, and Nithin Ramadurai from Olivo Laboratories, set out to develop a protective coating that could restore the properties of healthy skin, for both medical and cosmetic applications. It easily returned to its original cream jar state after being stretched more than 250 per cent. This type of “second skin” could also be adapted to provide long-lasting ultraviolet protection, researchers said. As skin ages, it becomes less firm and less elastic — problems that can be exacerbated by sun exposure. These polymers can be assembled into a network arrangement known as a cross-linked polymer layer (XPL).They created a library of more than 100 possible polymers, all of which contained a chemical structure known as siloxane — a chain of alternating atoms of silicon and oxygen.The best-performing material has elastic properties very similar to those of skin.Scientists, including those of Indian-origin, have developed a new material that can temporarily tighten skin, smooth wrinkles, and may be used to deliver drugs to treat skin conditions such as eczema
