In the pursuit of a delicate and refined appearance, face slimming injections have become a highly sought – after cosmetic procedure for many beauty enthusiasts. Many often wonder, “How much does a single face slimming injection cost? How long does the effect of a face slimming injection last?” Understanding these aspects can help us make more informed decisions when choosing face slimming injection treatments.
The main component of face slimming injections is botulinum toxin. It works by blocking the nerve impulses between nerves and muscles, relaxing over – contracted muscles, and thus achieving the effect of slimming the face.
This treatment is especially suitable for individuals with wide faces caused by masseter muscle hypertrophy. However, the price of face slimming injections is not fixed and is influenced by several factors.
Geographically, in first – tier cities, due to the high cost of living and significant operational expenses for medical aesthetic institutions, the price of a single face slimming injection typically ranges from 2000 to 6000 yuan. In second – and third – tier cities, the price may drop to 800 – 3000 yuan. The price differences among cities mainly stem from local economic development levels and market competition.
Brands and product types also significantly impact the price. Imported brands such as Botox are relatively expensive, with a single injection costing between 3000 and 6000 yuan, thanks to their high purity and advanced manufacturing processes.
Domestic brands like Hengli are more budget – friendly, usually priced at 800 – 2000 yuan. Additionally, products with different concentrations and specifications have varying prices.
Regarding “how long does the effect of a face slimming injection last,” generally, the effects of face slimming injections start to become noticeable about 1 – 2 weeks after injection, and the most significant results are seen 2 – 3 months later. The duration of the effect usually lasts for 4 – 6 months. After that, as the botulinum toxin is gradually metabolized by the body, the masseter muscle gradually regains some strength, and the facial shape may rebound slightly.
However, with regular multiple injections, the masseter muscle remains continuously inhibited, and the duration of the effect can gradually be extended. Some people can even maintain the effect for 8 – 12 months.

In addition to price and duration, people have many other questions about face slimming injections. Here are answers to some frequently asked questions.
Q: Are face slimming injections suitable for everyone?
A: Not really. Pregnant women, breastfeeding women, individuals with neuromuscular diseases such as myasthenia gravis and multiple sclerosis, and those who are allergic to botulinum toxin are not suitable candidates for face slimming injections.
Moreover, for people whose facial fullness is caused by fat accumulation or broad bone structure, face slimming injections are unlikely to achieve the desired results, and these individuals need to choose other targeted methods.
Q: Are there any side effects of face slimming injections?
A: There may be some short – term side effects. For example, redness, pain, and bruising may occur at the injection site, which usually subside on their own within 1 – 2 days.
Some people may also experience mild facial asymmetry, difficulty swallowing, or an unnatural smile, but most of these symptoms are temporary and will gradually ease as the effect of the botulinum toxin diminishes. Choosing a regular medical aesthetic institution and a qualified doctor can significantly reduce the likelihood of side effects.
Q: What should I pay attention to after getting face slimming injections?
A: Avoid getting the injection site wet or touching it within 6 hours after the injection to prevent infection. Avoid spicy and thrill foods, as well as hard and chewy foods, within a week to reduce masseter muscle activity.
Refrain from facial massage, hot compresses, and high – temperature saunas for a month to avoid accelerating the metabolism of botulinum toxin and affecting the effect. At the same time, it is essential to follow the doctor’s instructions for care and follow – up appointments strictly.
