Q: What are the regular domestic Botox, Dysport Botox, and Korean “pink” and “white” Botox? A: At present, only domestic Botox-HengLi and imported Botox-BOTOX are approved in China. Other botulinum toxins are not listed in China at present, and Dysport is still in the process of approval. Q: I’ve had Botox in beauty salons before, and I’m not sure about the specific brand, but now I want to change to another kind of Botox. However, I heard that there are often cases of Botox “drug resistance”, and I am worried. A: The common reasons for Botox “drug resistance”: 1. 2-3 injections of Botox within a month. 2. One-time injection of more than 300 units of Botox. 3. Injections of informal Botox. 4. Mixed use of Botox, such as the last time with Hengli, this time with “powder”. Q: Can you use Botox during oral contraception? Q: Can Botox be used during oral contraceptive use? A: Yes. Q: Can Botox be used during menstruation? A: Yes. Q: Can I use Botox if I am allergic to penicillin? A: Yes. However, if you are more worried, you can use Botox skin test, the principle is the same as penicillin skin test Q: Can I use Botox during pregnancy preparation? After Botox, if I find that I am pregnant, do I need to choose abortion? A: Studies have shown that Botox has a very small probability of causing teratogenicity. It is generally recommended not to conceive within six months after Botox injection. If pregnancy occurs during this period, abortion is not recommended as the injected dose is usually less than 100 units. It is recommended that regular obstetric tests, such as ultrasound, be performed during pregnancy. Q: Does it hurt to have a face slimming injection? A: It does not hurt. Since the injection needle is at least 30G or even finer, it is much more comfortable than any other routine cosmetic surgery you may have. If you are particularly afraid of pain, you can use compound lidocaine cream externally for 45-60 minutes before the operation. Q: Can I have a face slimming injection to slim down fat and bone? A: Facial thinning injection can only make muscle atrophy once and for all. Lipolysis injection can be used to thin fat. There is no reliable bone-slimming injection. Q: Can 3-4 sequential injections of face slimming injection slim my face permanently? A: No. There have been studies confirming serial Botox injections for face slimming at intervals of 6-12 months, with longer intervals between each injection. The longest interval can be more than 1 year. And the “rebound” of the biting muscle after injection is much slower. And a large number of clinical cases also confirm this point of view. Q: I have a big bite muscle, is it okay to inject 100 units on one side of my face? A: No. At present, there is no case of bite muscle hypertrophy that requires 100 units of injection on one side. And from the large number of clinical follow-up, most of the single unilateral injection dose is less than 50 units. For a thicker bite + wider lower face, a second Botox injection is recommended after 4 months. Later on, it will be gradually extended to 6-12 months. Q: I heard that Botox can slim down the face + face lift A: For those with less subcutaneous fat and unclear jaw margin, Botox can be applied to the biting muscle, and at the same time inject the cervical latissimus dorsi muscle, which in turn relaxes the localization and clarifies the jaw margin. Q: Will face slimming injection damage the facial nerve? Why do I see some people have a bit of unilateral drooping of the corners of the mouth? A: There is no facial nerve trunk distribution at the site of Botox injection in the biting muscle. Therefore, there is no needling of the facial nerve. However, if the injection site is close to the corner of the mouth, or leaning upward, excessive massage after surgery may diffuse and involve the zygomaticus major muscle, resulting in localized ptosis. Q: I have a few sisters around me who have had face slimming injections, and as a result, they look older. More worried about their own face is not satisfied A: Botulinum toxin face thinning is not satisfied with the main reasons: 1, bilateral asymmetry: preoperative bilateral facial / bite muscle asymmetry. After injecting equal doses of botulinum toxin, the asymmetry is aggravated. Need to measure in detail before surgery. If necessary, high-frequency ultrasound to measure the thickness of the biting muscle, you can predict the effect of surgery 2, sagging facial skin, nasolabial fold deepening: after the biting muscle atrophy, the local support decreased, especially those who had loose skin before surgery. It is recommended to reduce the injection dose. If it is still heavy after half a year, you can consider non-surgical facial enhancement. It is generally not recommended to do fat filling first 3. Deepening of zygomatico-cheek sulcus: due to the diffusion of botulinum toxin to the upper part of the biting muscle, the local support decreases, resulting in local relative concavity. For preoperative zygomatic arch wider, especially need to pay attention. It is recommended that the injection point should be downward, with BOTOX (diffusion coefficient is small) Q: What should I pay attention to the thin face injection? 1, prohibited aminoglycosanoid antibiotics, such as streptomycin, gentamicin, carbamazepine, butylcarbamazepine, tobramycin – may affect neuromuscular conduction and amplify the effect of botulinum toxin. 2.Banned from arrow toxin-like muscle paralyzing drugs 3.Banned from patients with severe heart, liver, kidney and lung diseases. 4, prohibited for neuromuscular system diseases, such as myasthenia gravis, multiple sclerosis, etc. 5, rest in the hospital for 10-15 minutes, do not massage, hot packs. Do not massage or apply hot compresses. Leave the hospital after there is no discomfort. 6. Avoid biting hard after injection, such as beef, peanuts, etc., to prevent the bite muscle from “rebounding” quickly. Q: What are the common complications of face slimming injection? A: After botulinum toxin injection, common complications include: local pain, bruising, numbness, edema, headache, dizziness, stiff expression. Systemic symptoms: fever, malaise, poor appetite, and even diplopia, swallowing and breathing difficulties. Rarer: white spots at injection sites, granulomatous granulomas of the skin and abnormal muscle bulges. Q: how to give the concept of backwardness of the parents that hit the thin face injection will lead to infertility A: this truly inexperienced, you can: 1, citing countless celebrities after thinning the face, still pregnant examples 2, translation of the English literature for them to see 3, you can find the corresponding television video
