Facial slimming injections have a limited duration of effect. Below is information on how long the results typically last.
Facial slimming injections refer to Botox (botulinum toxin) injections. Originally used to smooth expression lines, it has been discovered to be remarkably effective for facial slimming.The mechanism of facial slimming injections involves blocking nerve impulses to muscles. This relaxes overly contracted muscles and temporarily paralyzes overdeveloped ones, achieving a slimmer facial appearance. The effects of Botox injections develop gradually, typically becoming noticeable within two weeks to a month after the procedure.
The primary component of facial slimming injections is botulinum toxin, which is not as frightening as its name suggests. Many beauty clinics refer to it as "biological wrinkle reduction" or "genetic wrinkle reduction" to alleviate people's apprehensions. Due to its nerve-blocking properties, it is widely used in neurology, ophthalmology, plastic surgery, and cosmetic surgery. The current dosage is only one percent of its maximum safe dose, making it extremely safe.
For treating masseter hypertrophy, 1–2 injection sites per side are typically selected. Injections should be administered as slowly as possible. No local massage or special post-treatment care is required; normal chewing motion allows the solution to gradually diffuse within the muscle tissue. Masseter atrophy and facial contour changes become observable approximately one month after injecting Type A botulinum toxin.
Following botulinum toxin type A injection, local adverse reactions primarily include excessive weakness of the masseter muscle and corresponding effects due to toxin diffusion into adjacent muscle tissue. These clinical manifestations correlate with the injection site and toxin dosage. Some patients may experience fever, discomfort, or fatigue after injection. These symptoms are generally transient and resolve spontaneously within several weeks.The effects of botulinum toxin injections typically last about one year, after which recurrence is possible, but repeat injections can be administered.
