Introduction
The primary purpose of administering slimming injections (瘦脸针) is to improve the facial contour through muscle relaxation. The general reference price for slimming injections ranges from 2000 to 6000 yuan per session, and noticeable improvement is usually observed within 1 to 3 months. Typically, effects become visible 2 to 4 weeks after the injection, although the exact timeframe may vary depending on individual constitution and recovery status.

瘦脸 injections primarily achieve facial contour improvement through muscle relaxation. The general reference price for a session is 2000-6000 yuan, and visible improvement can usually be seen after 1-3 months. Typically, effects become noticeable 2-4 weeks after the injection, although the exact timeline may vary.

The瘦脸 injection mainly works by injecting medication to cause facial muscle atrophy, thereby achieving a slimming effect on the face. After administration, effects typically become gradually visible within 2-4 weeks, with variations depending on individual constitution and recovery status.

If one's constitution is good and recovery is quick, the medication may start showing effects in about 2 weeks. However, for those with a weaker constitution and slower recovery, it may take longer—usually around 4 weeks—to see noticeable results. After receiving a瘦脸 injection, proper post-treatment care is important, including maintaining clean and hygienic skin.

It is also important to maintain healthy lifestyle and dietary habits, and to avoid frequently chewing hard foods, which may cause the masseter muscles to enlarge and affect the desired outcome.
