As more people consider treatments for acne scars, attention has turned to techniques that reach different skin depths and can be adjusted to individual needs.
Traditional microneedling and radiofrequency (RF) microneedling work on similar principles but differ in how deeply they act and the types of concerns they may address. Choosing between them depends on factors such as scar type, skin sensitivity, and recovery time.
Dr Justin Boey assesses these factors during consultation, guiding you through the decision-making process and recommending an approach that aligns with your skin goals, while prioritising safety and suitability.
In this article, you’ll learn about how traditional microneedling and RF microneedling work, their uses and limitations, and the considerations that may guide your decision.
What Is Traditional Microneedling?
Traditional microneedling involves using a handheld device equipped with fine needles to create controlled micro-injuries in the skin. These microchannels initiate the skin’s natural healing process, which in turn promotes the production of collagen and elastin.
It’s commonly used to improve skin tone and texture, reduce mild acne scars, and refine the appearance of pores.
How Traditional Microneedling Works
During the procedure, microneedles penetrate the skin at controlled depths, depending on the treatment area and skin concern. The micro-injuries trigger a wound-healing response, encouraging the production of collagen to help strengthen the skin barrier and smooth out surface irregularities over time.
Traditional microneedling does not use heat, relying solely on the mechanical action of the needles to stimulate the body’s natural healing response. This makes it a suitable option for individuals seeking collagen stimulation without the use of thermal energy.
What Is RF Microneedling?
RF microneedling takes the traditional approach a step further by combining microneedles with radiofrequency energy. This added thermal component supports collagen contraction and dermal remodelling, often contributing to additional skin tightening.
This method is frequently used to manage moderate to severe acne scars, skin laxity, and uneven skin texture.
How RF Microneedling Works
RF microneedling devices use ultra-fine needles to penetrate the skin while simultaneously emitting radiofrequency energy. This thermal energy targets the dermis to promote more intensive collagen and elastin production.
The combination of mechanical injury and thermal stimulation supports deeper collagen restructuring, making this treatment suitable for more pronounced acne scarring and skin laxity.
A hospital-based study evaluated microneedling with radiofrequency in 44 patients with acne scars and reported statistically significant improvement after four sessions, with minimal downtime and a favourable safety profile in skin types III–V.
Comparing RF Microneedling and Traditional Microneedling
Your choice between traditional and RF microneedling comes down to your specific skin concerns, treatment goals, recovery expectations, and comfort level. Use the table below to compare both options and prepare for a more focused discussion with your medical practitioner.
| Feature | Traditional Microneedling | RF Microneedling |
|---|---|---|
| Mechanism | Mechanical needling only | Microneedling combined with radiofrequency energy |
| Heat Delivery | No heat | Yes, controlled thermal energy into the dermis |
| Collagen Stimulation | Gradual collagen induction over multiple sessions | Dual stimulation (mechanical + heat) for a more concentrated effect |
| Acne Scar Suitability | Mild to moderate acne scarring | Moderate to more established acne scarring |
| Downtime | Typically 1–3 days | Typically 2–5 days |
| Skin Tone Suitability | Higher pigmentation risk in darker skin types | Generally safe for all Fitzpatrick skin types |
| Recommended Sessions | 4–8 sessions | 2–4 sessions |
| Treatment Cost | Generally lower per session | Generally higher due to device complexity |
RF microneedling provides greater treatment versatility and longer-term improvements, particularly for patients with more complex skin concerns. However, traditional microneedling remains a suitable and cost-effective option for mild scarring and general rejuvenation.
Which Acne Scars Respond Best to Each Treatment?
Not all acne scars are the same. Understanding their characteristics helps determine which treatment may be most appropriate.
- Ice pick scars: Narrow and deep, often extending into the dermis
- Boxcar scars: Broad with defined edges, usually shallow to moderately deep
- Rolling scars: Wavy, sloped edges that create a textured appearance
RF microneedling is typically considered more suitable for deeper or atrophic scars, such as rolling or boxcar types. Its ability to target the dermis more deeply, while delivering controlled heat, can support tissue remodelling beneath the scar.
Traditional microneedling is beneficial for surface-level irregularities, including textural changes, mild boxcar scars, and post-inflammatory hyperpigmentation. When performed consistently over several sessions, you may notice gradual changes in skin texture and tone.
Suitability for Different Skin Types
Skin types are often classified using the Fitzpatrick scale (I–VI), which ranges from very fair (Type I) to deeply pigmented skin (Type VI).
For individuals with darker skin tones (Types IV–VI), treatment safety is an important consideration. Traditional microneedling, when performed too aggressively, may increase the risk of post-inflammatory hyperpigmentation due to repeated trauma to the epidermis.
RF microneedling offers a method of thermal coagulation that focuses its energy deeper within the dermis, reducing surface trauma. This can lower the risk of pigment changes in darker skin, especially when the treatment is customised with insulated needles and depth control features.
Regardless of skin type, treatments must be performed under medical supervision with appropriate protocols to minimise risks and maximise benefits.
Downtime, Side Effects, and Recovery
Both treatments involve micro-injuries to the skin, which can lead to temporary side effects such as redness, swelling, mild sensitivity, and dryness or flaking.
Traditional microneedling generally involves 1–3 days of recovery. Redness often improves within 24 to 48 hours, causing minimal disruption to daily activities.
RF microneedling may require a slightly longer recovery period of 2–5 days, depending on the intensity of the treatment. Some individuals may experience lingering redness or mild crusting, which typically resolves with appropriate aftercare.
How to Support Skin Recovery and Results After Microneedling
- Avoid retinoids, acid-based products (such as glycolic or salicylic acid), and exfoliants for 3 to 7 days prior to treatment.
- Cleanse your skin thoroughly before treatment to ensure it’s free from makeup, sunscreen, and dirt.
- Avoid sun exposure and tanning beds for at least 24 hours before your session.
Post-Treatment: Support Recovery
- Apply gentle, hydrating, and soothing skincare products. Avoid active ingredients immediately after treatment.
- Keep the treated area clean and moisturised. Use cool water to gently cleanse your face and pat it dry.
- Avoid sun exposure, makeup, exercise, saunas, and swimming for 24 to 72 hours after treatment.
- Use a cold compress to relieve redness or swelling if needed.
- Apply a broad-spectrum mineral sunscreen (SPF 30 or higher) to protect healing skin.
Microneedling is typically done over a series of sessions, spaced about 4 to 6 weeks apart. This gives your skin time to recover between treatments and supports collagen remodelling, which may continue for several months after the final session.
When to Consider Each Treatment
- Severity of acne scarring: Deeper or more stubborn scars may respond better to RF.
- Skin tone: RF microneedling is generally suitable for various skin tones, including darker ones, when carried out using proper techniques and settings.
- Budget: Traditional microneedling may be an option for those managing mild concerns or seeking gradual improvement.
- Recovery time: Those with limited downtime may opt for traditional treatments.
An in-person assessment allows for a personalised treatment plan suited to your skin goals and condition.
