Botulinum toxin is a common minimally invasive anti-aging item commonly used to remove wrinkles and slim the face. Because it has a certain degree of toxicity, a series of adverse reactions brought about by deviations in injection positioning, level and dosage, as well as bilateral injection asymmetry, can result in unnatural facial expressions, mild cosmetic effects, and in severe cases, short-term effects on vision and certain effects on daily life. The following is for you to analyze – botulinum toxin in wrinkle removal, if the injection deviation, what complications there will be, and how to treat. 1, eye opening effort Reason: The frontalis muscle is the only muscle in the upper face that contracts in the upward direction, and forehead wrinkle injection can lead to a weakening of the power of the frontalis muscle to lift upward, as well as a downward shift in the position of the eyebrows. This side effect is unavoidable and can only be reduced as much as possible. Treatment: ① patiently wait for a period of time; ② local heat physiotherapy, sauna or usually do more exercise (after the recovery period), to promote the body’s basal metabolic rate; ③ use new Stimulus or new Florin eye drops, can have some relief; ④ with 0.2% adrenaline containing eye drops for 10 days continuously, 3-5 times a day. 2, lower eyelid laxity Cause: When injecting the eyelid striae, the dot position is too much to the inner side, or when injecting the lower eyelid striae, the injection dose is too much, which makes the orbicularis oculi muscle relax, causing the appearance of eyebags to aggravate, and in heavy cases, the flaccid type of lower eyelid ectropion. Treatment: ① patiently wait for a period of time; ② local hot compress physiotherapy, sauna or usually more exercise (after the recovery period) to promote the body’s basal metabolic rate. 3.Impact on vision Causes: Most commonly, the injection point of the corners of the eyes is inward, the dose is too much, and it penetrates into the extraocular muscles, thus affecting the movement of the eyes. Frontal lines, interbrow lines injected too much, too deep and penetration can also have some impact on the extraocular muscles, customers appear blurred vision, focusing difficulties, early summer superimposed shadow, photophobia and tearing, pupil dilation and other symptoms. Treatment: ① patiently wait for a period of time; ② local heat physiotherapy, sauna or usually more exercise (after the recovery period) to promote the body’s basal metabolic rate; ③ photophobia is serious, you can wear sunglasses, minimize the use of eyes; ④ the use of Neostigmine or Neoforin eye drops, can have some relief; ⑤ with 0.2% epinephrine continuous eye drops for 10 days, 3-5 times a day. 4, expression distortion Cause: facial expression muscle distribution is complex, if the injection point is wrong, bilateral injection asymmetry (asymmetry of dose, point and level) or due to excessive injection amount, and penetration to the surrounding muscles, resulting in facial expression stiffness, abnormal contraction or asymmetry, with a smile when crooked mouth is most common. Treatment: ① Wait patiently for a period of time; ② Psychotherapy is the main treatment for those with less serious symptoms; ③ Local heat therapy, sauna or exercise (after the recovery period) to promote the body’s basal metabolic rate; ④ On the side with normal or slightly hyperactive muscle strength, find the most suitable balance force point and try to inject a small amount of higher concentration of Botox; ⑤ Strictly comply with the principle of “less is better than more ⑤ Strictly observe the principle of “less rather than more”. 5, lip closure difficulties Reason: chin muscle is the only muscle of the lower lip to contraction force upward, normal shut up when the chin muscle is in a relaxed state, the force suction mouth or pout action when the chin muscle contraction. When the amount of chin muscle injection is too much, or the injection point position is upward, resulting in drug penetration into the orbicularis oris muscle area, the lips close with effort, or even difficult to close, unconscious salivation, and foreign body feeling at the lower gums. Treatment: ① wait patiently for a period of time; ② local hot compress physiotherapy, sauna or usually more exercise (after the recovery period) to promote the body’s basal metabolic rate; ③ psychotherapy as the main treatment.
