Acne scars can leave a lasting impact, not just on the skin but on confidence and daily life. For many individuals, conventional treatments often fall short of delivering lasting improvement. However, clinical evidence continues to support newer, more advanced options. 

In a study published in September 2024, 76.3% of patients reported significant improvement in their acne scars within three months of completing their final session of Microneedling Radiofrequency (MNRF) treatment.

In this blog, we’ll explain what MNRF for acne scars is and how it works. You’ll also learn about its key benefits, what to expect during and after the procedure, who it suits best, potential side effects, comparisons with other treatments, and cost considerations.

Overview

• Microneedling RF uses controlled radiofrequency and microneedles to target deeper layers of skin, improving acne scars and texture over time.
• It’s suitable for different scar types like ice-pick, rolling, and boxcar scars, especially when done under a dermatologist's guidance.
• Recovery is minimal with temporary redness or dryness; visible improvement is typically seen over multiple sessions.
• Compared to chemical peels or traditional microneedling, RF-enhanced microneedling offers deeper collagen stimulation with better long-term results.
• At Velantis Dermatology, all procedures are done by MD dermatologists using medical-grade protocols, focused on safety, science, and your skin’s long-term health.

What is Microneedling RF?

Microneedling Radiofrequency, or MNRF, is a minimally invasive dermatological procedure that combines controlled microneedling with radiofrequency energy to target deeper layers of the skin for therapeutic skin remodelling.

How MNRF Treats Acne Scars

Here is how the treatment supports scar improvement:

• Creates Controlled Micro-Injuries: Fine needles create micro-channels in the skin, which stimulate the body’s natural wound-healing response.
• Delivers Radiofrequency Energy Deep Into the Skin: Radiofrequency heat is transmitted through the needles into the deeper dermal layers without damaging the surface.
• Stimulates Collagen and Elastin Production: The combined effect of microneedling and heat encourages new collagen and elastin formation, essential for repairing scarred tissue.
• Targets Scar Tissue at the Root: MNRF works beneath the skin’s surface, where acne scars often begin, leading to more effective and long-lasting results.
• Promotes Skin Remodelling Over Time: As healing progresses over several weeks, the treated area gradually becomes smoother and more even in texture.
• Minimises Thermal Damage to Surrounding Skin: The energy is delivered in a focused manner, reducing the risk of unwanted damage and helping support a safer recovery process.
• Customisable Based on Scar Type and Depth: Treatment settings can be adjusted to suit different scar patterns and skin types, allowing for individualised care.

Key Benefits of MNRF for Acne Scars

MNRF offers several therapeutic benefits by working below the surface of the skin to repair and remodel scar tissue. Here are the key ways it supports improvement in acne scars.

• Stimulates Collagen Production: Radiofrequency energy delivered through microneedles promotes new collagen and elastin, helping to gradually reduce scar depth and improve skin structure.
• Targets Deep Scar Tissue: Unlike surface treatments, MNRF works in the deeper dermal layers where scars form, allowing for more precise and effective results.
• Effective for Multiple Scar Types: Suitable for treating boxcar, rolling, and ice-pick scars, with measurable improvement seen in clinical scar grading.
• Low Risk of Pigmentation Issues: Minimal impact on the skin surface lowers the risk of post-inflammatory hyperpigmentation, making it safer for darker skin tones.
• Improves Overall Skin Texture: The treatment also supports skin tightening and smoother texture as a secondary benefit of dermal stimulation.

Who is the Ideal Candidate?

Microneedling RF is most effective when matched to the right skin condition and individual. Here’s who may benefit the most from this treatment.

• Atrophic Acne Scars: Best suited for deep, indented scars left behind by acne, as it helps rebuild collagen.
• All Skin Tones: Safe for both light and dark skin without a high risk of pigmentation changes.
• Uneven Skin Texture: Can smooth out rough patches, enlarged pores, and mild skin laxity over time.
• Good Overall Health: Recommended for individuals who do not have any major health conditions affecting healing.

Who Should Avoid This Treatment?

While MNRF is safe for many, there are some cases where the procedure should be postponed or avoided:

• Active Acne or Skin Infections: Skin should be free of breakouts or infections to avoid worsening irritation or spreading bacteria.
• Keloid-Prone Skin: Not advised for those with a history of raised, thick scars, as MNRF may trigger a similar response.
• Pregnancy: Usually postponed during pregnancy due to limited safety data on the procedure.
• Slow Wound Healing: Conditions like uncontrolled diabetes may delay recovery or increase the risk of side effects.

What to Expect During and After the Procedure?

Before starting treatment, it’s natural to want clarity on what the process involves. Here’s what typically happens before, during, and after an MNRF session.

1. During the Procedure

Microneedling RF is performed in a controlled, clinical setting under the supervision of a trained professional. The steps below outline what you can expect on the day of treatment.

• Initial Assessment: Your doctor will first ask about your medical history and check your skin to make sure MNRF is the right treatment for your scars. This helps them plan your care safely and accurately.
• Skin Preparation: The target area is carefully cleansed and disinfected using antiseptic agents to reduce any risk of infection.
• Topical Anaesthesia: A numbing cream is usually applied about an hour before the procedure so you feel little to no pain. In some cases, it might not be needed if the treatment is gentle.
• MNRF Application: A special device with tiny needles is used to create small injuries in your skin. At the same time, it sends heat (radiofrequency energy) into deeper skin layers to help with healing.
• Custom Settings: The doctor adjusts the depth of the needles (usually between 0.5mm to 2.5mm) and the heat level based on your skin type and scar depth.
• Procedure Time: The whole session usually takes between 30 to 60 minutes, depending on how big the area is.
• Technique Used: The device is moved gently across your skin in a pattern to cover the full area evenly.
• Optional Add-ons: After treatment, some clinics may apply a serum or Platelet-Rich Plasma (PRP) to help with healing and boost results.

2. After the Procedure

Post-treatment care is a key part of your recovery and results. While downtime is generally minimal, following the right aftercare can support healing and maximise the effectiveness of each session.

• Immediate Reaction: Right after treatment, your skin may look red or feel slightly swollen, like a mild sunburn. This usually settles down in a few days. Some people might notice tiny spots of bleeding or light bruising.
• Managing Discomfort: You can apply a cold pack to reduce swelling. Your doctor may also suggest using a mild moisturiser or cream to help your skin heal.
• Sun Protection: Avoid going out in strong sunlight for a few days. Always use sunscreen to protect your skin while it heals.
• Makeup Use: You can usually wear makeup the next day, but apply it gently to avoid irritating the skin.
• Skincare Precautions: Stay away from strong skincare products, scrubs, or other treatments until your skin has healed.
• Treatment Frequency: MNRF typically requires multiple sessions spaced 4 to 6 weeks apart to achieve noticeable improvement in acne scars.
• Gradual Results: Your skin improves slowly over the next few weeks as collagen builds. Scars will gradually look smoother, and your skin texture may feel more even.

Side Effects MNRF for Acne Scars

While MNRF is a safe and effective treatment for acne scars, it's normal to notice a few temporary side effects as your skin begins to heal.

• Mild Discomfort or Warm Sensation: A slight burning or tingling feeling can be felt during or after treatment. Most people describe it as mild and short-lived.
• Dryness or Peeling: Some skin flaking may occur as part of the natural healing and renewal process.
• Temporary Pigmentation Changes: In rare cases, skin may darken or lighten slightly, especially if exposed to sunlight without proper protection post-procedure.
• Pinpoint Bleeding or Mild Bruising: Minor surface bleeding or small bruises may happen during treatment, but these usually fade quickly.
• Infection (Rare): There is a small risk of infection if aftercare instructions aren’t followed properly. Keeping the area clean greatly reduces this risk.

Cost of MNRF Treatment for Acne Scars

Microneedling RF is seen as a cost-effective option for reducing acne scars, especially when compared to other high-end treatments. In Chennai, the cost depends on a few important factors. 

On average, a single session may cost anywhere from ₹4,000 to ₹15,000. Some premium clinics may charge ₹20,000–₹25,000 per session, depending on your skin needs and the clinic’s reputation.

Factors That Influence Pricing

The overall pricing varies based on several important factors:

• Treatment Area: Full-face treatments cost more than smaller areas, like just the cheeks or chin.
• Number of Sessions Needed: Most people need around 3 to 6 sessions. So, the full treatment may range from ₹12,000 to ₹90,000.
• Severity of Acne Scars: Deeper or more widespread scars may need more sessions, which increases the total cost.
• Experience of the Dermatologist: Clinics run by highly experienced dermatologists often charge more, but you also get better safety, accuracy, and care.
