How many days does it take for slimming facial injections to show effects at the earliest?
Disease description:
I've always had a lot of facial fat, and weight loss hasn't been very effective. I received a瘦脸针 (facial slimming injection) two weeks ago, but now I still don't see any noticeable difference. I'd like to ask how many days it usually takes for the effects of facial slimming injections to become visible?

The results of slimming injections vary from person to person, but noticeable facial slimming effects typically begin as early as about two weeks after injection. This is primarily because the main ingredient, botulinum toxin type A, requires a certain amount of time to take effect. It works by blocking nerve signals and inhibiting the activity of the masseter muscles, causing them to gradually atrophy and thereby achieving a slimmer facial appearance.
During the first two weeks following injection, the drug is actively taking effect. During this period, avoid facial massage and be gentle when washing your face. Additionally, to maintain the slimming results, it is advisable to avoid eating nuts and minimize activities that engage the masseter muscles.
Note that although the effects of slimming injections usually become visible around two weeks post-injection, optimal results are typically achieved within 1 to 3 months. The duration of the effect varies among individuals, generally lasting between 4 to 7 months, after which repeat injections may be needed to maintain the desired outcome.
