Low Frequency Ultrasound for Scars

Low-frequency ultrasound (LFU) is increasingly used in medical therapies, including the treatment and healing of scars.

Mechanism of Action

  1. Mechanical Stimulation:
    Low-frequency ultrasound generates sound waves that penetrate tissues. These sound waves create mechanical vibrations within the skin and underlying tissues. The vibrations can enhance cellular activity, such as fibroblast function, which is critical for the production of collagen—a protein essential for skin structure and healing.
  2. Increased Blood Flow:
     The mechanical energy from the ultrasound helps to increase circulation in the targeted area. Improved blood flow delivers more oxygen and nutrients, which accelerates the healing process and aids in the remodelling of scar tissue.
  3. Stimulation of Cellular Processes:
    • Collagen Production: Ultrasound therapy promotes the production of new collagen fibres, which are necessary for scar remodelling. Over time, the new collagen fibres help flatten and soften scars, making them less noticeable.
    • Fibroblast Activation: The vibrations stimulate fibroblasts, the cells responsible for producing collagen and elastin, which helps in wound healing and tissue repair.
    • Reduction in Inflammation: Low-frequency ultrasound can reduce inflammation in the surrounding tissue, which can limit scar tissue formation or prevent excessive scarring (such as keloid or hypertrophic scars).
  1. Cavitation:
    Low-frequency ultrasound produces microscopic gas bubbles in the tissue fluids through a process called cavitation. When these bubbles burst, they create small, localised pressure changes that stimulate cellular activities and tissue healing without damaging the surrounding skin. This effect helps break down the dense scar tissue, promoting more flexible and less visible scar formation.

Low Frequency Ultrasound Clinical Benefits for Scars

  • Reduction in Scar Thickness: Studies have shown that LFU can reduce the thickness of scars, including hypertrophic scars and keloids.
  • Improvement in Scar Texture: Over time, LFU therapy can improve the overall texture and flexibility of scars, making them smoother and less rigid.
  • Minimised Pain and Discomfort: For patients experiencing pain or discomfort due to scar tissue, ultrasound therapy can reduce this by increasing circulation and reducing inflammation in the affected area.

Low Frequency Ultrasound Applications

Low-frequency ultrasound is typically applied in physical therapy settings or specialised dermatological treatments.

It is non-invasive, generally painless, and can be used in combination with other scar treatments such as silicone gels or corticosteroid injections.

Low Frequency Ultrasound for Scars FAQ

What frequency ultrasound is used?

Low-frequency ultrasound generally operates in the range of 1 to 3 kHz.

What is the benefit of using low frequency instead of high?

Lower frequency ultrasound can penetrate skin tissues more deeply. This makes it ideal for treating conditions like deep scars.

How many treatments will I need and how often?

Treatments are often delivered in short sessions, lasting around 5-15 minutes, with multiple treatments over weeks or months depending on the severity of the scar and the treatment goal.

Is low-frequency ultrasound suitable for all types of scars?

Low-frequency ultrasound may be effective for a variety of common scars, including:

  • Hypertrophic scars: These are raised, thickened scars that often occur after injury or surgery.
  • Keloid scars: These are overgrowth of scar tissue that extend beyond the original wound boundary.
  • Old scars: Ultrasound can help to improve the appearance of even old scars.

What limitations should I be aware of?

Treatment effectiveness depends on the nature of the scar e.g., fresh scars may respond better than older, well-established scars.

This treatment is not suitable for all patients: People with certain conditions, like deep vein thrombosis or malignancies in the area of treatment, may not be suitable candidates for this therapy. Please contact Clinicbe for advice.

Are there any side-effects with low frequency ultrasound treatment?

Low-frequency ultrasound is generally considered to be a safe and well-tolerated treatment. However, some people may experience mild redness or discomfort at the treatment site.

Can low-frequency ultrasound be combined with other scar treatments?

In some cases, low-frequency ultrasound may be combined with other scar treatments, such as dermal fillers, microneedling, radio frequency or laser/IPL, for optimal results.

Clinicbe offers a wide range of treatment options and we excel in creating highly effective programmes designed to suit the individual.

What is the cost of low-frequency ultrasound scar treatment?

The cost of skin treatment can vary depending on the treatment area, the number of sessions required, and the geographic location. Please see our online price list for indicative costs or enquire for more information.
