What are the risks of using eye wrinkle injections?

Generally, "wrinkle-relaxing injections" refer to Botulinum Toxin Type A for injection. The mechanism of Botulinum Toxin Type A for injection involves blocking signal transmission between nerves and muscles to reduce muscle contractions, thereby softening or eliminating dynamic wrinkles. The general reference price of Botulinum Toxin Type A for injection is 1000–3000 yuan per injection. Noticeable improvement is usually seen within 1–2 days after the procedure, although symptoms such as itching and redness may occur. Potential risks associated with Botulinum Toxin Type A injections include local swelling or redness, bruising, pigmentation, unnatural facial expressions, and ptosis of the upper eyelid. Detailed explanations are as follows:

1. Local swelling or redness

Following the use of Botulinum Toxin Type A for injection around the eyes, local reactions such as swelling or redness may occur due to drug irritation and injection trauma, although these typically do not affect normal eye function.

2. Bruising

During the administration of Botulinum Toxin Type A injections, minor blood vessels around the eyes may be damaged, causing blood leakage and accumulation in the subcutaneous tissue, resulting in localized bruising around the eyes.

3. Pigmentation

During the administration of Botulinum Toxin Type A injections, superficial injection or inadequate sun protection after the procedure may lead to pigmentation of the periorbital skin, causing darkening of the skin around the eyes and affecting aesthetics.

4. Unnatural facial expressions

If the injection site is too low or excessive dosage is used, the drug may affect facial muscles such as the zygomaticus major and zygomaticus minor muscles, leading to unnatural facial expressions, such as an inability to lift the cheeks symmetrically when smiling, resulting in an unnatural appearance.

5. Ptosis of the upper eyelid

During the administration of Botulinum Toxin Type A injections, the drug may seep downward along the orbital rim and diffuse into the levator palpebrae superioris muscle, potentially causing incomplete elevation of the upper eyelid, which may affect vision and the aesthetic appearance of the eyes, and in severe cases, may lead to visual impairment.

It is recommended to visit a reputable hospital and use Botulinum Toxin Type A for injection under the guidance of a physician to ensure effectiveness and safety. Adequate sleep should be ensured after the procedure, and a light diet rich in vitamins should be consumed to promote skin recovery.
