How to Treat Acne Scars with Micro-Needling and RF


Acne is a skin condition that commonly affects people of all ages. It can leave behind scars that can affect one’s self-esteem and confidence. 

Fortunately, several treatments are available to reduce the appearance of acne scars, and one of the most influential and popular treatments is micro-needling with radiofrequency (RF).

In this blog, we’ll discuss what micro-needling with RF is, how it works for acne scars and the safety of this procedure.

What is Micro-needling with RF?

Micro-needling with RF is a minimally invasive cosmetic procedure that combines traditional micro-needling with radiofrequency energy. During the procedure, a device creates tiny punctures on the skin’s surface, which triggers the skin’s natural healing process.

Radiofrequency energy is then delivered to the deeper layers of the skin. This helps to stimulate collagen production and further enhances the skin’s healing process.

How does Micro-needling with RF work for Acne Scars?

Acne scars result from damage to the skin’s collagen fibers caused by inflammation from acne. Micro-needling with RF works to improve the appearance of acne scars in several ways:

  • Stimulates collagen production:
    • By creating micro-injuries in the skin, micro-needling with RF triggers the body’s natural healing process, including collagen production. Collagen is a substance that gives the skin its structure and elasticity, and by stimulating collagen production, micro-needling with RF can help to improve the appearance of acne scars.
  • Promotes skin rejuvenation:
    • Radiofrequency energy applies heat to the skin’s deeper layers, which helps stimulate cell turnover. This improves the overall appearance and texture of the skin.
  • Reduces scar appearance:
    • By stimulating collagen production and promoting skin rejuvenation, micro-needling with RF can help reduce acne scars’ appearance.

Is Micro-needling with RF safe for Acne Scars?

Micro-needling with RF is generally considered safe for most people. However, as with any aesthetic procedure, there are some risks and potential side effects to consider. Some possible side effects include:

  • Redness and swelling:
    • It is normal to see redness and swelling following the procedure. But this should only persist for a short time.
  • Bruising:
    • Some patients may experience bruising at the site of treatment.
  • Infection:
    • While rare, there is a risk of infection following any cosmetic procedure. It is essential to follow all aftercare instructions provided by your provider to reduce this risk.
  • Hyperpigmentation:
    • Some patients may experience hyperpigmentation (skin darkening) following the procedure.

How Many Sessions of Micro-needling With RF Are Needed for Acne Scars?

The number of sessions required to achieve desired results may vary depending on the severity of acne scars and individual skin type. Most patients require three to six treatments spaced four to six weeks apart. Your provider will be able to give you a better idea of how many sessions you may need during your initial consultation.


Micro-needling with RF is a safe and effective treatment for reducing the appearance of acne scars. By stimulating collagen production and promoting skin rejuvenation, this procedure can help to improve the texture and overall appearance of the skin.
