Usually, 24 hours after the face slimming injection, i.e. the next day, you can wear makeup. When injecting face slimming injections, generally use a very fine needle to inject Botox into the muscle of the bite muscle, the eye of the needle is small and can be closed and recovered after 4-6 hours. Just one day after the injection, it is best not to wash your face or press your face, so as not to just inject the botulinum toxin spread to the surrounding tissues, affecting the effect of thinning the face or serious adverse consequences. A day later, the needle eye of the injector closes, the wound recovers, the position of botulinum toxin is basically fixed, and some ingredients in cosmetics will not enter the needle hole to cause wound infection or react with the botulinum toxin inside, so it does not affect tissue repair. In addition, people who play face slimming injection need to pay attention to not lying down within 6 hours after surgery, do not wash your face, do not massage the injection site, avoid hard food, spicy food, etc. If there is any discomfort, go to the plastic surgery department in time.
