We have all been there – dealing with acne and acne scars is a different level of struggle. Acne may fade, but the scars it leaves behind can affect our confidence for years. Finding the right treatment for acne scars, regardless of type, is essential for visible, long-term improvement.
Suppose you have been searching for the best treatment for acne scars in Chennai. In that case, there is one procedure that dermatologists consistently recommend for Indian skin types – Microneedling Radiofrequency, commonly called MNRF. It combines the precision of microneedling with the power of controlled radiofrequency heat. Together, they stimulate deep collagen regeneration and skin remodeling. The result is a smoother texture, shallower scars, and healthier-looking skin with minimal downtime.
At Welona Skin, Hair, Body, and Laser Clinic in Chennai, MNRF is one of the most sought-after treatments for acne scars because of its safety, effectiveness, and suitability for Indian skin. In this detailed guide, you will understand what makes MNRF a top choice for the treatment of acne scars, how the procedure works, the types of scars it treats, what results to expect, and why Welona’s dermatologists trust this technology.
Why Acne Scars Are So Hard to Treat
Acne scars form when inflammation destroys collagen in the dermis, leaving behind:
- Rolling scars (wavy, uneven depressions)
- Boxcar scars (sharp-edged craters)
- Icepick scars (narrow, deep pits)
Unlike surface blemishes, these are structural defects, so topical products can’t reach them. To treat pitted and indented scars, you need an acne scar treatment that reaches the deeper dermal layers. This is where MNRF stands out: it triggers collagen remodeling beneath the surface rather than treating only the topmost layer of the skin.
What Is MNRF?
MNRF (Microneedling Radiofrequency) is an FDA-cleared, minimally invasive procedure that combines:
- Ultrafine insulated needles (penetrate 0.5–3.5mm deep)
- Controlled radiofrequency (RF) energy (delivered only at the needle tip)
This duo bypasses the epidermis and delivers heat precisely to scarred dermis, triggering:
- New collagen (type I & III)
- Elastin regeneration
- Gradual lifting of depressed scars
It helps in the following ways:
- Stimulates new collagen formation
- Strengthens existing collagen
- Breaks down old scar tissue
- Improves skin texture and firmness
- Smoothens pitted and boxcar scars
- Enhances overall glow and skin quality
A 2024 case series in the IP Indian Journal of Clinical and Experimental Dermatology reported 60–80% improvement in acne scars after just 3–4 MNRF sessions, with no post-inflammatory hyperpigmentation in Fitzpatrick skin types IV–V.
Why Dermatologists Recommend MNRF for Treatment of Acne Scars
Safe for Indian skin
MNRF works below the surface, which reduces the risk of post-inflammatory hyperpigmentation. This makes it particularly suitable for all Indian skin tones. That’s why even men are choosing MNRF for their skin rejuvenation.
Works on Different Types of Acne Scars
MNRF shows improvement in a wide range of scars, such as:
- Rolling scars
- Boxcar scars
- Atrophic scars
- Mixed acne scars
- Enlarged pores
- Surgical scars
It is one of the few treatments that can visibly improve deep, stubborn scars.
Stimulates Natural Collagen
Instead of adding collagen from outside, MNRF encourages your skin to rebuild its own structural support. This leads to long-lasting, natural-looking results.
Minimal Downtime
Most people resume regular activities within a day. Mild redness or swelling settles quickly.
Precise Depth Control
Dermatologists can adjust needle depth and energy levels based on your scar type, which ensures targeted treatment and better outcomes.
Effective When Combined with Other Treatments
For severe scars, MNRF is often combined with:
- Subcision
- PRP therapy
- Chemical peels
- TCA Cross
- Microdermabrasion
This makes it a versatile treatment option.
How MNRF Works on Different Acne Scar Types
| Scar Type | Typical MNRF Approach | Expected Result |
| Rolling Scars | Deeper RF (2.5–3.5mm) + optional subcision | 70–80% softening |
| Boxcar Scars | Medium depth (2.0–2.5mm) + fractional pattern | 60–70% filling |
| Shallow Icepick | Focused high-energy pulses | 50–60% reduction |
| Mixed Scars | Staged protocol: subcision → MNRF → TCA if needed | 75%+ overall |
How MNRF Treatment Works Step by Step at Welona
At Welona, MNRF treatments are performed by trained dermatologists using advanced, FDA-approved devices. A session usually takes about 30 to 45 minutes. Here is what a typical session looks like:
Step 1: Skin Consultation and Analysis
Your dermatologist examines the type, depth, and overall skin condition of the scar. A customised plan is prepared based on the severity of scars.
Step 2: Cleansing and Numbing
The skin is cleansed, and a numbing cream is applied to ensure comfort during the procedure.
Step 3: Microneedles Penetrate the Skin
Microneedles create precise microchannels in the deeper layers of the skin.
Step 4: Radiofrequency Energy Delivery
RF energy is delivered through the needles to heat the dermis and stimulate collagen. This controlled thermal damage helps break old scar tissue.
Step 5: Cooling and Soothing
A cooling mask or serum is applied to soothe the skin and reduce any redness.
Step 6: Post-Treatment Care
You will receive aftercare instructions, which include gentle cleansing and sun protection.
How Many MNRF Sessions Are Needed
The number of treatment sessions for acne scars depends on the depth and skin response. General guidelines:
- Mild scars: 2 to 3 sessions
- Moderate scars: 3 to 5 sessions
- Severe scars: 5 to 6 sessions, sometimes with combination therapy
Your dermatologist at Welona will create a customised plan tailored to your skin.

FAQs: MNRF Treatment for Acne Scars
Is MNRF safe for all skin types?
Yes. MNRF is considered one of the safest acne scar treatments for Indian skin because it focuses on deeper layers without damaging the surface.
How painful is the treatment?
You may feel a mild pricking sensation, but numbing cream makes the session very comfortable.
How long is the downtime?
Most people experience redness for a few hours. You can resume your routine the same day or the next day.
Can MNRF remove scars completely?
No treatment can erase scars fully. MNRF significantly improves texture and depth, often by 50-80 percent, depending on scar severity.
Is MNRF better than laser?
For Indian skin, MNRF is often safer than aggressive lasers and offers results similar to or better than those of aggressive lasers for deeper scars.
When will I see results?
You can expect visible improvement within a few weeks, with the best results appearing over two to six months.
Can I apply makeup after MNRF?
It is best to wait at least 24 hours. Your dermatologist will guide you based on your skin’s condition.
Are there any side effects?
Side effects are minimal and may include redness, mild swelling, or temporary dryness, which settle quickly.
How should I take care of my skin after the treatment?
Use gentle products, avoid harsh actives for a few days, and always apply sunscreen.
Can MNRF treat pigmentation as well?
Yes. While its primary purpose is scar reduction, many people notice brighter, more even-toned skin as collagen rebuilds.
