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 suffers. Cosmetologists around the world have been trying to stop this process for millennia, however, without much effect. Another attempt was made by experts from the Massachusetts Institute of Technology (MIT), who developed an invisible polymer coating, smoothing wrinkles and protecting the skin from various misfortunes.

Conditionally, the coating can be called a second skin. It is applied in two stages. Initially, the chemical structure – siloxane, containing atoms of silicon and oxygen, spreads over the skin in the form of a transparent cream. Then a platinum catalyst, which converts siloxane into the crosslinked polymer Xpl layer, enters into operation.

The resulting material is invisible and in elasticity and appearance corresponds to the skin of a young man . During the testing, the researchers closed the XPL-layer bags under the eyes, after which they remained almost invisible during the day.

In another experiment, scientists tested the moisturizing abilities of the “second skin”. After a couple of hours after application, the XPL layer retained much more liquid than commercial moisturizers. None of the participants in the tests recorded any skin irritation from the new material.

Researchers say that after some modifications the XPL-layer will be able to provide long-term protection against ultraviolet radiation.
