Anti-wrinkle injections are a safe and effective means of minimising the appearance of wrinkles. They help to smooth specific muscles in the face that result in wrinkles. Anti-wrinkle injections are commonly used on frown lines, crow’s feet, and forehead lines to create a younger, refreshed look. Anti-wrinkle injections work after around 7-14 days and can last for 3-4 months. They can be used together with dermal fillers to help eliminate both static and dynamic wrinkles.
