Anti-Wrinkle Injections Explained: How They Work, Benefits & Safety
Anti-wrinkle injections are one of the most widely requested non-surgical aesthetic treatments in the UK. They are commonly used to soften expression lines, refresh facial appearance, and help prevent deeper wrinkles from forming over time.
This guide explains how anti-wrinkle injections work, the benefits, safety considerations, and what to expect from treatment.
What Are Anti-Wrinkle Injections?
Anti-wrinkle injections use a purified protein that temporarily relaxes targeted facial muscles. By reducing muscle movement in specific areas, the skin above appears smoother and more relaxed.
They are most commonly used to treat dynamic wrinkles — lines caused by repeated facial expressions such as smiling, frowning, or squinting.
Common Treatment Areas
Anti-wrinkle injections can be used in several facial areas, including:
- Forehead lines
- Frown lines (between the eyebrows)
- Crow’s feet (around the eyes)
- Bunny lines (nose wrinkles)
- Lip lines
- Jawline and neck (in selected cases)
A personalised consultation helps determine which areas are suitable based on facial anatomy and goals.
How Do Anti-Wrinkle Injections Work?
The treatment works by temporarily blocking nerve signals to the targeted muscles. This reduces muscle contraction, allowing the skin to smooth out while still maintaining natural facial expression when performed correctly.
The effects are not permanent, which allows treatments to be adjusted over time for balanced, natural-looking results.
Benefits of Anti-Wrinkle Injections
✔ Smoother Appearance
They may help soften fine lines and wrinkles, particularly those caused by facial movement.
✔ Preventative Benefits
Regular treatment may help reduce the development of deeper lines by limiting repetitive muscle movement.
✔ Quick Treatment Time
Appointments typically take 10–20 minutes, making them easy to fit into a busy schedule.
✔ No Surgery or Downtime
Most people return to normal activities immediately after treatment.
✔ Natural Results When Done Correctly
When administered conservatively, facial movement is maintained while lines appear softened.
When Will Results Be Visible?
Initial effects: Often start to appear within 3–5 days
Full results: Typically visible at around 10–14 days
Results generally last 3–4 months, depending on metabolism, muscle strength, and lifestyle factors.
Safety and Regulation in the UK
Anti-wrinkle injections are prescription-only medications in the UK. This means:
- A medical consultation is required before treatment
- Treatments should only be administered by appropriately trained medical professionals
When carried out correctly, anti-wrinkle injections have a strong safety profile. Side effects are usually mild and temporary and may include:
- Redness or swelling at injection sites
- Minor bruising
- Temporary headaches
Serious complications are rare when treatment is performed by an experienced practitioner following proper assessment.
What Happens During the Treatment?
- Facial muscles are assessed at rest and in motion
- Injection points are marked if needed
- Small amounts of product are injected using a fine needle
- The area is cleaned and aftercare advice is provided
Most people describe the sensation as brief pinpricks.
Aftercare Advice
After treatment, it is usually recommended to:
- Avoid rubbing the treated area for 24 hours
- Remain upright for at least 4 hours
- Avoid strenuous exercise for the rest of the day
- Follow practitioner-specific aftercare instructions
These steps help reduce the risk of product migration and optimise results.
Who Is Suitable for Anti-Wrinkle Injections?
Anti-wrinkle injections may be suitable for individuals who:
- Have visible expression lines
- Want a refreshed, rested appearance
- Prefer non-surgical treatments
They may not be appropriate during pregnancy or breastfeeding, or for individuals with certain medical conditions. A consultation ensures suitability and realistic expectations.
