The formation of crow’s feet is mainly due to the decrease of collagen fiber synthesis and degeneration of elastic fibers in the skin dermis as we grow older, resulting in the decrease of skin elasticity and the increase of wrinkles around the eyes. Crow’s feet generally appear after the age of 30, but there are many cases of crow’s feet before the age of 30, mainly due to genetics; secondly, the natural environment also has a great influence, sun exposure, dryness, cold, etc. lead to the loss of elasticity of fibrous tissue, which will also accelerate the production of crow’s feet; some personal bad habits are also the accomplices of crow’s feet, such as long-term lack of sleep, smoking, etc. How to eliminate or improve crow’s feet should be selected according to your own situation, and the most suitable method is the best for you. Botox injection Recommended index: ★★★★★ This is the most widely used non-surgical method to remove crow’s feet, it is through the injection of biological agents to block the nerve signal transmission between the nerves and muscles of the wrinkled skin, so as to relax the over-contracted muscles of the eyes, and then make the dynamic wrinkles disappear, to achieve the purpose of wrinkle flattening. Advantages: safe and simple, obvious results, no recovery period. Disadvantages: The maintenance time is only 4-6 months, and regular injections are required. Only for sports wrinkles, for static crow’s feet can only be improved. Injections need to be precise and the dosage is appropriate, otherwise it is easy to produce a “mask face” with stiff facial muscles. Recommended filler material: Hyaluronic acid ★★★★ Collagen ★★★★★ Hyaluronic acid and collagen are injected into the dermal folds and depressions in the form of filler, which can achieve the effect of wrinkle removal. Advantages: hypoallergenic and non-rejection, simple operation and quick recovery. It is good for static deep lines where Botox does not work. Disadvantages: maintenance time can only be about 6-9 months, need regular injection. Laser Recommendation index: ★★★★ Laser can effectively improve facial skin laxity, remove deep wrinkles and make the whole face lift. Advantages: simple, quick recovery, and high acceptance by patients. Disadvantages: A few people will have a long period of redness and reactive pigmentation after treatment, which affects the efficacy. Autologous fat filler injection Recommendation index: ★★★ Autologous fat injection is extracted from the patient’s own fat, processed in vitro to become fat particles, and then injected into the crow’s feet to fill the effect of smoothing wrinkles. Advantages: no rejection of autologous fat, long maintenance time after fat activation. Disadvantages: the skin at the corners of the eyes is very thin, it is difficult to evenly distribute the injected fat, and it is easy to be uneven; the effect of wrinkle removal is uncertain, and the effect on the superficial deep lines is poor; anesthesia is needed, and the recovery time is long. Surgical facelift method Recommendation index: ★★★ The surgical method is to make an incision in the hairline, tighten the loose temporal skin, and at the same time separate the lateral edge of the orbicularis oculi muscle and suture it to a spreading position. Advantages: better results for severe crow’s feet with significant skin laxity. Disadvantages: requires open surgery, relatively traumatic, long recovery period, prone to complications such as scarring and damage to facial nerve branches. Anti-wrinkle, start from the smallest section. In order to avoid premature creeping of crow’s feet to the corners of the eyes, it is recommended to moisturize the skin and massage properly. Avoid excessive exposure to ultraviolet light, which leads to photoaging of the skin. In addition, bad habits such as staying up late and smoking need to be corrected.
