Introduction
In general, "瘦脸针" (injections for facial slimming) refers to Botulinum Toxin Type A for injection. It achieves a slimming effect by blocking the release of acetylcholine, preventing muscle fibers from contracting and reducing muscle strength. The general reference price for Botulinum Toxin Type A injections is 1,500 to 6,000 yuan per injection. Noticeable improvement is usually seen within 7 to 10 days after the procedure, although side effects such as facial swelling may occur.
Under normal circumstances, "slimming needle" refers to botulinum toxin type A for injection, which achieves a face slimming effect by blocking the release of acetylcholine, preventing muscle fibers from contracting and weakening the force of muscle contractions. The general reference price for botulinum toxin type A for injection is 1500-6000 yuan per injection. Noticeable improvement is usually seen within 7-10 days after the procedure, but may be accompanied by symptoms such as swelling and bruising. Botulinum toxin type A for injection may cause side effects, including facial discomfort, swelling and bruising, temporary numbness, allergic reactions, and muscle atrophy. If any discomfort occurs, please seek medical attention promptly. Detailed analysis is as follows:
1. Facial Discomfort
For a period after the injection, facial discomfort such as pain, tightness, or itching might occur. These symptoms typically resolve on their own within about a week.
2. Swelling and Bruising
Mild swelling and bruising may appear on the face after the injection, caused by damage to local blood vessels during the injection process. These symptoms usually subside within a few days after the injection.
3. Temporary Facial Numbness
Within a few days after the injection, temporary numbness may occur on the face, due to nerve endings being damaged from the needle piercing the skin. This numbness typically disappears within a few days after the injection.
4. Allergic Reaction
Some individuals may be allergic to the components of botulinum toxin type A for injection, presenting symptoms such as redness, swelling, itching, or rash. Applying an ice pack or cold towel gently to the affected area can help constrict blood vessels and reduce inflammation.
5. Muscle Atrophy
Repeated or long-term injections of the slimming needle may affect facial muscle function and even lead to muscle atrophy. Applying a hot water bottle or warm towel to the facial muscles can promote blood circulation and help muscle recovery.
When undergoing the above procedure, it is recommended to visit a legitimate hospital and have the treatment performed under the guidance of a qualified physician to ensure both safety and effectiveness.
