A deep horizontal line on the earlobe, there are two main reasons: 1, physiological reasons, this reason occurs in the middle-aged and older people are more common, it is mainly skin atrophy, caused by a wrinkle-like changes, and the wrinkles on the face of the human face is roughly the same. It causes wrinkles, mainly as people get older, the body’s collagen loss gradually. Without enough collagen to support the body’s skin, there is not enough protein material to provide the skin with nutrients to hold it up. This situation may lead to skin atrophy, inducing skin aging, skin sagging and wrinkles and other manifestations. In this case, the clinic also has no good way to deal with, because this is the human body aging is inevitable; 2, pathologic reasons, some patients, such as ear capillary protrusion caused by the performance. Because there are a lot of capillaries, if the capillaries localized varicose, will lead to the appearance of skin wrinkles. The reason may be that the earlobe local impact by external forces, or sleep with extrusion and other factors, resulting in local blood supply situation is abnormal. Because the human ear place blood supply is very difficult, if the local blood supply obstacles, manifested in the skin is the local blood supply of the skin is insufficient, resulting in the appearance of transverse lines, wrinkle-like changes in the skin.
