Crow’s feet are generally due to the aging of the human body cells, which leads to the skin dermis at the corners of the eyes of the collagen breaks, losing the original elasticity of the formation. Botulinum toxin is a kind of neurotoxin, through the injection of appropriate amount of botulinum toxin at the end of the eye, can block the nerve impulses generated by acetylcholine and muscle surface receptors, thus inhibiting muscle contraction facial muscles can not be contracted, and the skin is at the same time in the state of stasis, so as to achieve the elimination of facial power wrinkles and the effect of face thinning. The risks of Botox removal of crow’s feet surgery are as follows: 1, Botox injection may appear after discomfort, allergies, etc.; 2, Botox removal of crow’s feet, if the operation is not appropriate, it can lead to facial nerve paralysis and lifting the eyebrow difficulty or eyebrow sagging, as well as the emergence of facial allergic phenomena such as cicatrization of the skin’s redness and swelling; 3, Botulinum toxin injection dosage is not reasonably controlled may lead to Botulinum toxin toxicity, thus inhibit respiration making the patient die; 4. As the crow’s feet are closer to the eyes, the eyelid muscles may be paralyzed and the eyes may become smaller. Facial wrinkles are caused by facial expression muscle activity. When Botox is used to treat crow’s feet, 3-8 points are injected in each side of the outer eye area, which can make the muscle activity that causes crow’s feet weaken, thus reducing crow’s feet, and the obvious effect can be seen around one week and days after the injection.
