What Are Anti-Wrinkle Injections?
Anti-wrinkle injections use a purified protein called botulinum toxin type A. A doctor injects small amounts into selected facial muscles. The protein blocks the nerve signal telling the muscle to contract. The muscle relaxes, and the skin above the muscle smooths out.
Doctors have used botulinum toxin in medicine for decades, for eyelid spasm, chronic migraine and heavy sweating. Aesthetic use follows the same principle at low doses.
How Do Anti-Wrinkle Injections Work on Lines?
Your face shows two main types of lines. Each type responds differently.
- Dynamic lines: Show when you move your face, for example when you frown or smile. These respond well to anti-wrinkle injections.
- Static lines: Stay visible at rest. Injections soften these over repeat treatments. Deep static lines often need fillers or skin treatments as well.
Anti-wrinkle injections relax muscles. Dermal fillers add volume. Read anti-wrinkle injections vs dermal fillers to compare the two.

Frequently Asked Questions
Do anti-wrinkle injections give a frozen look?
A frozen look comes from high doses. Doctor-led dosing softens lines and keeps your natural expressions.
What happens if you stop treatment?
Movement returns gradually, and lines return to their earlier state. Stopping does not make lines worse.
At what age do people start?
Many people start between their late 20s and 30s, once lines stay visible after movement. Read preventative anti-wrinkle injections.
Do men suit anti-wrinkle injections?
Yes. Men often have stronger facial muscles, so the doctor adjusts the dose and keeps a natural brow shape.
Is combining anti-wrinkle injections and fillers in one visit possible?
Yes, in many cases. Your doctor decides whether one visit or two suits your plan.
How long does the appointment take?
The injections take 15 to 20 minutes. Allow extra time for your first consultation.
