Scientists from Japan conducted a scientific study in which they found out the cause of the appearance of wrinkles on the forehead and around the eyes. Scientific translation from English. There are significantly fewer fatty glands around the eyes than on the forehead. Combined with a thin epidermis, this contributes to the appearance of deep wrinkles. The beauty industry makes billions of dollars in products that help get rid of crow's feet.
As practice shows, regular cosmetic procedures with their use have a positive effect, however, even the most expensive creams are not able to completely smooth problem areas, even the Red Diamond anti-wrinkle serum. Scientists from Japan managed to clearly explain the essence of this problem.
Scientists from Japan have found that the amount of fatty glands under the skin affects the depth and density of wrinkles. Therefore, they are always smaller on the forehead than around the eyes. They suspect that a small number of fatty glands in the eye area and a thin layer of epidermis in this area provoke excessive deformation of the skin.
As we age, the glands of our body begin to secrete less sebum, leaving exposed areas of the body defenseless against external stimuli. The epidermis stops moisturizing, as a result of which the skin dries out and begins to peel off. Its previous firmness quickly fades, triggering the premature aging that is increasingly troubling our generation of people.
The discovery was made by scientists from Japan's Kagoshima University and Jichi Medical University. They examined an area called the retinacular cutis, just above the muscle layer.
In the upper image, you can see fine wrinkles occurring in thin skin with a lot of large fat glands. The lower figure shows deep wrinkles, which also form in areas with a thin layer of the epidermis, but the number and size of the fatty glands are much smaller.
The study used 58 skin samples of deceased men and women. Scientists analyzed tissue from the forehead and eyes.
Each section of the epidermis was examined in detail, studying the number and density of the fatty or sebaceous glands. After that, the data obtained were compared with the size and characteristics of the wrinkles. The end results have shed light on the processes of skin deformation and aging.
While examining samples of thin skin from the forehead, scientists found that shallow and fine wrinkles form in areas where there are a large number of sebaceous glands, the density of which is significantly higher than in other areas.
In the areas around the eyes, where crow's feet are often formed, no such connection was found. Scientists speculate that this is due to the lack of sebaceous glands in the area.
In their work, researchers from Japan say that one of the main factors in the appearance of wrinkles is the density of the fat and sebaceous glands. If the value of this indicator is high, then the skin always remains hydrated and practically does not deform. Otherwise, the epidermis dries up and loses its elasticity. This explains the differences between fine lines on the forehead and crow's feet in the eye area.
The study was presented in the Journal of Clinical Anatomy.
