Once the injection passes from the dermis to the desired muscle, the nerves become blocked; instead, their synapses are blocked by Botox. Therefore, even if the brain is activated and sends signals to the body to move a certain muscle, Botox effectively blocks that action and prevents the muscle from moving. The injected muscle can no longer contract, which causes wrinkles to relax and soften, and also helps prevent the formation of new ones. Intradermal botulinum toxin injection has an anti-wrinkle efficacy similar to intramuscular injection, but is characterized by a lower risk of ptosis and heaviness in the eyebrows. Multiple injections of lower doses of botulinum toxin appear to help achieve a satisfactory result and prevent systemic side effects.
Botox is a medication made from a neurotoxin produced by the Clostridium botulinum bacteria called botulinum toxin. When it comes to headaches, the effects of Botox on migraines have been discovered, Rowe explains to SELF. The objective of this study was to provide an overview of side effects related to Botox and to recommend possible preventive strategies and of treatment. It may appear as early as 48 hours or as late as 7 to 10 days after the injection and may persist for 2 to 4 weeks.
Platysmal injections in large doses (50 units or more) to correct prominent vertical bands and horizontal lines in the neck can cause neck flexor weakness and temporary dysphagia and, in rare cases, hoarseness. The appearance of ectropion after injection requires immediate attention to prevent exposure keratitis and corneal damage. Ecchymosis or bruising is usually the result of an injury to a blood vessel at the injection site and most commonly occurs around the eye area. Infection is a rare complication at the injection site and can occur with any procedure that breaks the skin barrier.
The doctor uses a fine needle to inject small amounts of botulinum toxin into the skin or muscles...
