Many beauty seekers know that Botox can slim the face and get rid of wrinkles. However, most people actually do not know much about Botox, and there are people asking questions about Botox in the backstage of Help Beauty App every day. Today, we are here to tell you the real “Botox”. Botulinum toxin type A is widely used in minimally invasive cosmetic surgery treatments, and it mainly plays two aspects of cosmetic effects. On the one hand, it acts on the chewing muscles (mainly the bite muscle) to achieve a slimming effect, and on the other hand, it acts on the facial expression muscles to improve the removal of power wrinkles. What is a face slimming injection? Face slimming injection is the injection of botulinum toxin into the bite muscle area, by making the bite muscle atrophy, to achieve the purpose of improving the shape of the lower face. The principle is to use botulinum toxin type A to block the neuromuscular conduction, so that the simple hypertrophy of the bite muscle relaxation, paralysis, and finally atrophy so as to achieve the purpose of slimming the face. Usually the effect starts in 3-4 days, and the best effect appears about 4-6 weeks after injection, and the effect is usually maintained for about 6 months. Botulinum toxin injection for wrinkle reduction (Botulinum toxin – expression muscle) facial expression muscle is different from skeletal muscle, the shape and function are relatively independent, most of them are connected with skin and superficial fascia soft tissue with fibers, so as to express facial expression in a fine way. Due to the long time reciprocal mechanical movement of facial expression muscles, wrinkles are produced on the skin (dynamic wrinkles), especially some habitual expression movements, excessive use of a certain piece or a certain group of expression muscles, so that they are in a long-term hyperactive state, gradually forming permanent wrinkles over time. The application of botulinum toxin injected into certain expression muscles that produce wrinkles will block the release of the neurotransmitter acetylcholine, thus causing a decrease in muscle tone or temporary paralysis of local muscles, and wrinkles (especially power wrinkles) can gradually improve and disappear. Injections are a safe and effective non-surgical way to remove wrinkles, using a micro-injector to inject a small amount of botulinum toxin into the muscles that produce wrinkles in several points accurately, blocking the release of the neurotransmitter acetylcholine, so that muscle tone decreases, activity is weakened, local muscle temporary paralysis paralysis, 2-4 days after injection, gradually began to take effect, generally 7-14 days wrinkle removal effect is more obvious, for forehead lines ( It is effective for forehead wrinkles, frown lines, crow’s feet, fine lines under the eyes, nasolabial lines, chin and neck wrinkles, especially for those who have early power wrinkles and less loose skin. The drug maintenance time is about 4-6 months. Is Botox harmful to the human body? Botulinum toxin is not metabolized by the liver and only acts on local muscles, which rarely causes serious systemic adverse reactions. However, we need to remind the majority of beauty seekers that botulinum toxin injection is not a simple cosmetic life project, but a medical project. It has strict professional requirements for drug configuration, drug dosage, injection location, injection depth and angle, and professional doctors must be familiar with relevant anatomical knowledge and the distribution of facial nerves and muscles, and must undergo a certain amount of time training before they can engage in cosmetic injection operations. Complications and side effects related to botulinum toxin injection: 1. headache, local rash, edema and cold-like symptoms after injection; 2. serious allergic reactions such as urticaria, soft tissue edema, respiratory distress, anaphylaxis are extremely rare, but once they occur, timely life support is necessary (choose a regular hospital to be safe and secure); 3. asymmetry occurs due to inaccurate injection dose; 4. bleeding or hematoma occurs when the needle pierces the blood vessels; 5. 5.After injection, ptosis, incomplete eyelid closure, unnatural bilateral eyebrow shape, flying eyebrows, and asymmetry of eyebrow height on both sides may occur; 6.Injections at the crow’s feet may cause diplopia and incomplete eye closure; 7.Injections of Botox in the middle of the face, some patients cannot make some expressions (especially micro expressions) after injection, and have mask-like feelings; (for the middle of the face) (for the middle of the face and nasolabial folds depression, soft tissue filler is a better choice, Botox injection must be carried out by experienced doctors, and the dose must be small); 8, the lower part of the injection of Botox, a few patients appear to smile unnaturally or asymmetrically, salivation; 9, Botox injection bite muscle early can have chewing weakness, soreness phenomenon, open wide mouth weakness, etc., especially for the first injection of patients more obvious; because of chewing habits The reason is that the speed of muscle atrophy is faster than the speed of surface skin compliance change or drug diffusion to the surrounding area, and the performance is generally mild, and the above problems tend to improve gradually after 2 months of injection; 10. 7-10 days after the initial treatment, a review should be conducted, at which time the treatment effect and complications begin to appear. A small number of patients may require additional injections . The following matters should be noted for botulinum toxin injection: 1. Stop using aspirin and aspirin-like drugs 14 days before injection; 2. Stop using cosmetics on the day of injection, and do not wash your face or put on makeup within 6 hours after injection, and you can resume makeup 1 day after injection; 3. Observe 20-30 minutes after injection and leave the hospital after confirming no discomfort; 4. Maintain a vertical position within 2-4 hours after injection and avoid lying flat; 5, Do not massage the area on the day of injection to prevent the spread of Botox to the surrounding area; 6. Avoid eating hard food after injection; avoid spicy and stimulating food, smoking and alcohol for one week; 7. Avoid strenuous exercise 1-2 days after injection; 8. It is best to come to the hospital for follow-up after 10-14 days of injection. Botulinum toxin is not suitable for people: 1, allergic to the components of the injected products or allergies are prohibited (for example, eggs and other proteins); 2, pregnant women, within 6 months of preparing for pregnancy and lactation is prohibited; 3, under 18 years of age should not be injected; 4, the simultaneous use of aminoglycoside antibiotics should not be injected; 5, myasthenia gravis, multiple sclerosis and other immune diseases or those suffering from organic diseases should not be injected.
