Facial wrinkles are a major sign of aging, and it is not an exaggeration to say that they are a sign of age. What are the methods to eliminate wrinkles? What are the advantages and disadvantages between them? First of all, we need to know that there is no one method to eliminate all wrinkles, different types of wrinkles and different parts of the body need different methods to solve. Usually we divide wrinkles into dynamic and stationary. Dynamic wrinkles are wrinkles that do not appear when there is no expression, and resting wrinkles are wrinkles that appear at rest and worsen when making expressions. At present, there are two main methods of treatment for wrinkles: injection and surgery. Botulinum toxin injection is the most commonly used injectable wrinkle removal method. The face is the only part of the body where the muscles are close to the skin. No other part of the body can express emotions through automatic or involuntary contraction like the facial expression muscles. When the expression muscles contract, they can move the skin of the face, creating wrinkles and folds perpendicular to the muscular alignment. Botulinum toxin can cause temporary paralysis and relaxation of skeletal muscles by blocking cholinergic nerve conduction, and can improve or eliminate wrinkles by temporarily weakening the hyperactive state of the expression muscles. Therefore, it is suitable for power wrinkles and is not effective for static wrinkles. When the injection range is wide, there will be unnatural facial expression and tightness, which is normal and will be relieved naturally. Hyaluronic acid injection The principle of hyaluronic acid wrinkle removal is to fill the depressed tissue with a small amount, so it can reduce the static wrinkles, and can also fill the nasolabial folds, apple muscle, chin and other parts. Its effective time is 6 to 9 months, and it needs to be injected again after the body degrades and absorbs it. If there is a wide range of wrinkles on the face or neck, surgery is needed when the desired effect cannot be achieved by simple injection, and wrinkle removal surgery can be performed for specific areas such as temporal area, forehead, or the whole face. The surgical incision will be designed in the hairline, behind the ear and other hidden areas, so it is not easy to find after healing. However, the long incision from the front of the ear to the back of the ear is used for wrinkle removal, which is traumatic and takes a long time, resulting in complications such as obvious postoperative scar, incisional alopecia, numbness and abnormal sensation in the operation area, which discourage a large proportion of beauty seekers. Fourth, PPDO buried thread wrinkle removal For light and moderate wrinkles on the face, a surgical operation is easy, safe, with immediate effect, little damage, fast recovery, not easy to be infected, almost no scar, the patient can easily accept the method – PPDO buried thread wrinkle removal. Absorbable protein thread (PPDO) is implanted under the dermis, which can stimulate the production of skin collagen and thicken and tighten the dermis on the basis of mechanical lifting, and finally achieve the dual effect of facial wrinkle removal and lifting.
