For those concerned about wrinkly old skin, It might be a creative solution: an elastic(有弹性的) “second skin” that can be smoothed on to make aged tissue look more youthful.
The wearable film, developed at the Massachusetts Institute of Technology (MIT), has shown promise in a series of small experiments where it was applied to wrinkles, under-eye bags and areas of dry skin. When applied to the face or body, the thin, transparent layer sticks to the skin and supports the tissue, making it look and behave like younger skin, its producers claim.
“What we've been able to do is create a cream that you can put on the skin, and then when it's on the skin it can actually form, essentially, an elastic second skin,” said Bob Langer, who led the research. Tests in the lab found that the polymer film (高分子膜), which is only 70 thousandths of a millimetre thick, reduced the appearance of wrinkles and under-eye bags, and helped keep moisture in areas of dry skin.
The layer is designed to be applied in the morning, then peeled off at night. In previous studies, the second skin withstood normal daily wear, and the stresses and strains of exercise and swimming, without falling off or causing irritation. It also survived exposure to rain.
“It's something you can wear for a whole day or longer, depending on the physical forces thatget applied to the area where it is worn, "said Daniel Anderson, who helped develop the product at MIT. “You can't tell you're wearing it.”
While normal cosmetics can mask imperfections on the skin, the new coating changes the way skin behaves by giving it the elasticity of young skin. It was developed with help from two companies.
