Are there any side effects from slimming injections?

Generally, side effects that may occur after receiving slimming injections include muscle relaxation and weakness, facial stiffness, local swelling and bruising, allergic reactions, and facial asymmetry. A detailed analysis is as follows:

1. Muscle relaxation and weakness

Slimming injections act at the neuromuscular junction by inhibiting the release of acetylcholine, thereby causing muscle relaxation. This may affect chewing and speaking abilities and could lead to weakened masseter muscles.

2. Facial stiffness

As slimming injections affect normal facial muscle movements, facial expressions may become unnatural. For example, the movement of mouth-corner muscles during smiling may be restricted, resulting in a stiff or unnatural smile.

3. Local swelling and bruising

The injection process may cause traumatic reactions in local tissues, leading to exudation of tissue fluid and subsequent swelling. Additionally, damage to subcutaneous blood vessels may result in blood leakage and bruising.

4. Allergic reactions

Some individuals may be allergic to ingredients in slimming injections, presenting symptoms such as skin itching and redness.

5. Facial asymmetry

This may result from uneven injection doses, inaccurate injection sites, or differing responses of the muscles on each side of the face to the injection. Facial asymmetry can impair aesthetic appearance and may require further correction.

If slimming injections are desired, it is recommended to visit a reputable medical facility and undergo the procedure under the guidance of a qualified physician. After treatment, proper post-operative care should be observed, including avoiding contact with water too soon to prevent interference with healing.
