Neurotoxin injections, such as Botulinum toxin (commonly known as Botox), are primarily used to treat dynamic wrinkles, which are wrinkles that form as a result of muscle movement. These wrinkles are typically seen in areas of the face that are prone to repeated muscle contractions, such as:
- Forehead Lines: Neurotoxin injections can effectively smooth horizontal forehead lines that appear when you raise your eyebrows or express surprise.
- Frown Lines: Also known as glabellar lines, these are the vertical lines that form between the eyebrows when you frown or concentrate. Neurotoxin injections can relax the muscles responsible for these lines, resulting in a smoother appearance.
- Crow’s Feet: These are the fine lines and wrinkles that radiate outward from the corners of the eyes when you smile or squint. Neurotoxin injections can help soften crow’s feet and reduce their appearance.
It’s important to note that neurotoxin injections primarily target dynamic wrinkles caused by muscle movements. They are less effective for static wrinkles, which are present even at rest and are caused by factors such as age-related collagen loss or sun damage. Static wrinkles may require additional treatments such as dermal fillers or skin rejuvenation procedures to achieve optimal results.
