Introduction

In general, it is recommended to go makeup-free when receiving a facial slimming injection. The injection process involves administering the substance into the face, and maintaining facial cleanliness is a crucial measure to reduce the risk of infection. If the face is not thoroughly cleansed after wearing makeup before the injection, impurities and oils from the cosmetics may enter the injection site, increasing the likelihood of infection and potentially causing adverse reactions such as redness, pain, and inflammation.

　　"Facial slimming injections," commonly refer to a cosmetic procedure that involves injecting botulinum toxin to reduce facial muscle activity, thereby achieving a slimmer facial appearance. The reference price for this procedure ranges from 2000 to 6000 yuan per session, with effects typically beginning to show about a week after injection. Generally, it is recommended to receive the injection without makeup. Detailed explanations are as follows:

　　Facial slimming injections require needle insertion on the face, and maintaining facial cleanliness is an important measure to reduce the risk of infection. If makeup is not thoroughly removed before injection, impurities and oils from the cosmetics may enter the injection site, increasing the likelihood of infection and causing adverse reactions such as redness and swelling, pain, and inflammation. Receiving the injection without makeup ensures a relatively clean facial surface, requiring only standard disinfection procedures before injection, effectively reducing the risk of infection.

　　Additionally, after receiving facial slimming injections, doctors usually recommend avoiding water contact on the face for a certain period to prevent infection. Without makeup, there is no need for special cleansing or makeup removal after the injection, making it easier to follow post-procedure care instructions and maintain a dry and clean facial environment, which is beneficial for recovery.

　　Before deciding to undergo facial slimming injection treatment, please be sure to consult a qualified physician and choose an appropriate treatment plan based on your individual health condition and the doctor's recommendations.
