As a rule, wrinkles, dry skin, thinning and loss of its colors are a natural part of aging. Most people can recognize the signs of aging every time we look in the mirror, but scientists have no standard way of measuring age without damaging the skin. Now, a group of Taiwanese researchers have developed a special microscope that can safely penetrate the skin's surface to determine the age-related changes in the skin . This microscope, experts say, you can create an index to measure the effectiveness of anti-aging agents. The authors develop say that tested the microscope on people 19 to 79 years. At the heart of the laser is a special infrared emitter can penetrate the epidermis and examine the condition of the lower layers of the skin.
Taiwanese experts say that for the system analysis technology is used HGM (Harmonic generation microscopy). Previously, the same method was used for the study of embryos. In this procedure, a concentrated beam of photons goes into the material. Here, the photons with a certain frequency range and, by interacting with the material, they create a "harmonica" - vibration at which you can accurately judge the structure of the material. Finally, the microscope is able to create three-dimensional images of the inner layers of the skin with a very high resolution. As a signal of the material specialists took basal keratin concentration is in 24 -, 47 -, 59 - and 69-year-olds are different. Experts say that the production of this element in the skin decreases with age and the age of patients at the data from microscopes were apparent exhaustion and gaps in the basal layer of keratin.
Researchers say their analysis to judge the true age of the skin, as stimulate the production of some of the subcutaneous elements is very difficult. On the other hand, the microscope gives an indication of how effective cosmetic anti-aging agent.
