MIT engineers develop an invisible second skin

Over time, human skin, alas, loses its elasticity, and wrinkles appear on it. The effect of aging is not only cosmetic - the protective function of the skin from radiation, toxins and temperature also suffers. For thousands of years, cosmetologists around the world have been trying to stop this process, however, without much effect. Another attempt was made by specialists from the Massachusetts Institute of Technology (MIT), who have developed an invisible polymer coating that smooths wrinkles and protects the skin from various misfortunes.

Conditionally, the coating can be called the second skin. It is applied in two steps. Initially, the chemical structure - siloxane, containing silicon and oxygen atoms, spreads over the skin in the form of a transparent cream. Then a platinum catalyst comes into play, converting the siloxane into a crosslinked XPL polymer layer.

The resulting material is invisible and in terms of elasticity and appearance corresponds to the skin of a young man. During testing, the researchers covered the bags under the eyes with XPL, after which they remained almost invisible for 24 hours.

In another experiment, scientists tested the moisturizing ability of the "second skin". A couple of hours after application, the XPL layer retained much more fluid than commercial moisturizers. None of the test participants reported skin irritation from the new material.

The researchers say that with some tweaks, the XPL layer will be able to provide long-term UV protection.
