Does the瘦脸针 (facial slimming injection) work?
Generally, the reference price for瘦脸针 (facial slimming injections) ranges from 800 to 3000 yuan, with visible improvement typically noticeable within 15 to 30 days. The effectiveness of facial slimming injections depends on individual symptoms. If the condition involves masseter muscle hypertrophy or broad facial development, these injections are usually highly effective. However, their effectiveness may be limited for facial obesity or sagging caused by fat accumulation or skin laxity. It is recommended to visit a正规 hospital (reputable medical facility) and undergo the procedure under the guidance of a qualified physician. Detailed analysis is as follows:

As a method of modern aesthetic medicine, facial slimming injections primarily achieve a slimming effect through the injection of medication. The main component is injectable botulinum toxin type A, which rapidly penetrates the subdermal layer after being injected into the face, causing the muscles to atrophy quickly and thus achieving a facial slimming effect. For individuals with masseter muscle hypertrophy or broad facial development, facial slimming injections are usually highly effective. The effects typically begin to appear within about a week after injection, with full results becoming evident after approximately one month.
However, for facial obesity or sagging caused by fat accumulation or skin laxity, the effectiveness may be limited. These conditions are more commonly addressed through other cosmetic procedures such as liposuction or facelift surgery. Additionally, if facial slimming injections are performed in unlicensed medical facilities or beauty salons, or administered by personnel without appropriate qualifications, the results may not be satisfactory.
In daily life, it is recommended to pursue beauty moderately, undergo treatment at a正规 hospital (reputable medical institution) after fully understanding the risks, and promptly consult a physician if any discomfort occurs. Facial slimming injections are not recommended for individuals allergic to botulinum toxin.
