Scientists from Newcastle University have developed a test to predict the rate at which age-related wrinkles appear. This smear determines whether the skin is aging prematurely.
By the time deep wrinkles appear on the skin, as a rule, it is already too late to do something drastic about it. But that could all change now, as researchers have developed a test that can detect premature skin aging before it even shows up. This is a simple smear that detects DNA damage in skin cells that results from sleep deprivation, sun exposure, or environmental factors.

Moreover, the test not only determines these damages, but also allows you to find out for what reasons they occur. And this will help eliminate the underlying cause or reduce its impact to a minimum, developing preventive strategies to prevent wrinkles even before they appear on the face. The researchers based their test on 15 years of skin aging experiments. A swab can be taken from the cheek or face area, then it is sent to the laboratory for research to detect damage to the mitochondria – the “rechargeable batteries” of our skin cells.

Based on this test, you can find out whether cells age prematurely, and if so, for what reason. The test results should prompt the person to change their lifestyle. For example, use more sunscreen. (READ MORE)
