How does botulinum toxin work? How often should botulinum toxin be injected?

Botulinum toxin wrinkle-removing injections are a common cosmetic method for removing wrinkles. Before the injection, you should ask clearly whether you can get the injection if you have this condition. So how often should botulinum toxin be injected?

Botulinum toxin is injected into the wrinkle area, which can effectively inhibit the release of acetylcholine in the presynaptic membrane of peripheral motor nerve endings, thereby blocking the information transmission between nerves and muscles, thereby achieving the purpose of wrinkle removal and beauty.

Generally speaking, the effect of Botox injection for wrinkle removal can last for 4 to 6 months, which means that patients generally only need to inject twice a year. However, if patients need to inject hyaluronic acid for facial rejuvenation, the duration of maintenance will vary depending on the brand of hyaluronic acid and the size of the molecular weight.

Botulinum toxin is one of the most common wrinkle-removing injection materials. Generally, there is no limit to the best age for Botulinum toxin wrinkle-removing injections. The appropriate age is determined by the age of each person's skin. The best age for wrinkle-removing injections is around 30 years old, because dynamic wrinkles usually appear around 30 years old. In addition, if you find wrinkles that are not easy to disappear at rest, then Botulinum toxin is also suitable.

1. Dysfunction of local muscles occurs. For example, when injecting the frontalis muscle, if the injection position is too low or the injection volume is too large, it will cause difficulty in raising the eyebrows. If the levator palpebrae superioris muscle is paralyzed, it will cause difficulty in opening the eyes. However, these conditions will gradually recover with the absorption of the injected drug;

2. If hyaluronic acid is injected for wrinkle removal, nodules will form if the injection is too shallow. If it enters the blood vessels, it will cause vascular embolism, and in severe cases, it will cause skin necrosis.

3. If botulinum toxin is used for wrinkle removal, if the normal usage amount is exceeded, it will cause botulinum toxin poisoning. If the injection site is wrong, it will cause more obvious harm, such as stiff and asymmetrical facial expressions, or overall facial disharmony.
