What are the precautions for getting a slimming injection for the face?

The main precautions for receiving a slimming facial injection include the following points: 1. Preparation before injection: Avoid the menstrual period, ensure there is no facial infection or inflammation, discontinue the use of aspirin-like medications for at least two weeks, keep the face clean, and avoid wearing makeup or consuming spicy foods. 2. Selection of injection facility: Be sure to choose a qualified medical institution for the injection, avoid using botulinum toxin obtained from illegal sources, and ensure injection safety. 3. Post-injection care: Avoid massaging the injection site to prevent the spread of botulinum toxin; avoid washing the face and wearing makeup for 6 hours, and avoid getting the injection site wet for 24 hours; refrain from eating overly hard foods and reduce chewing movements for one week; avoid smoking and alcohol consumption to prevent interference with the effectiveness. 4. Observation and follow-up: After the injection, remain at the medical facility for observation for 20-30 minutes and leave only after ensuring there are no adverse reactions; if any discomfort occurs, seek medical attention promptly.
