Why Medical-Grade RF Microneedling Outperforms Cosmetic Devices


Radiofrequency Microneedling (RF Microneedling) has become a central treatment in modern aesthetic medicine. Unlike topical creams or cosmetic facials, it works directly within the skin’s architecture to stimulate long-term repair. At Rosem Health in West Bridgford, we provide this treatment using medical-grade equipment in a clinical environment, ensuring both safety and effectiveness.


This article explains the science of RF Microneedling, the key differences between medical and non-medical devices, and what patients can realistically expect from treatment.


What Is RF Microneedling?


RF Microneedling combines two proven technologies:


  • Microneedling: A series of fine needles creates controlled micro-injuries in the skin. This triggers the body’s natural wound-healing response, stimulating new collagen and elastin.


  • Radiofrequency energy: Delivered through the needles into the dermis, controlled heat enhances collagen remodelling, tightening the skin and improving elasticity.


By combining mechanical and thermal stimulation, RF Microneedling addresses both surface texture and deeper structural changes in the skin.


How Collagen Remodelling Works


Collagen and elastin are the proteins responsible for skin strength and resilience. As we age, production slows, leading to wrinkles, laxity, and thinning.

RF Microneedling initiates a repair cascade:


  1. Inflammation (0–7 days)

    • Micro-injuries recruit growth factors and fibroblasts.

    • Heat from RF causes controlled coagulation in the dermis.

  2. Proliferation (1–6 weeks)

    • Fibroblasts lay down new collagen and elastin fibres.

    • Skin begins to thicken and remodel.

  3. Remodelling (6–12 weeks)

    • Collagen fibres reorganise, increasing tensile strength.

    • Visible tightening and smoothing become apparent.


This process explains why results develop gradually and continue to improve for weeks after the final session.


Medical-Grade vs Non-Medical Devices


Not all microneedling or radiofrequency devices are equivalent. The distinction between medical-grade and cosmetic-grade systems is critical for outcomes.


Depth of Penetration


  • Medical-grade devices: Can reach depths up to 4mm, targeting the dermis where collagen synthesis occurs.

  • Cosmetic devices: Typically limited to 0.5–1mm, affecting only the superficial epidermis.


Energy Delivery


  • Medical-grade systems: Deliver RF energy consistently and evenly across treatment zones. Settings are customisable to patient needs.

  • Non-medical systems: Often inconsistent, with limited control of energy intensity. This may lead to under-treatment or overheating at the surface.


Safety Oversight


  • Medical clinics: Treatment is performed under clinical protocols, with sterilisation, anaesthetic application, and emergency management capability.

  • Non-medical environments: Often provided in beauty salons without medical governance. This raises risks of infection, burns, or ineffective results.


Conclusion: only medical-grade RF Microneedling in a clinical environment provides the depth, energy precision, and safety required for genuine skin remodelling.


What RF Microneedling Can Treat


Scientific studies and clinical experience support its use in a range of conditions:


Skin ageing — fine lines, wrinkles, and thinning around the eyes and mouth

Laxity — lower face, jawline, neck, body and arms skin tightening

Under-eye bags — improved smoothness and support under the eyes

Acne scars — smoothing of pitted scars and uneven texture

Traumatic and surgical scars — regeneration of healthy tissue and blending with skin

Stretch marks — stimulating repair in stretched dermal tissue


At Rosem Health West Bridgford, we can effectively treat:

Evidence from Clinical Studies


  • A 2020 systematic review in the Journal of Cosmetic Dermatology found RF Microneedling to be effective for acne scars, with significant improvement in texture and patient satisfaction.

  • A 2019 study in Lasers in Surgery and Medicine demonstrated measurable tightening of skin laxity with high patient tolerance and minimal downtime.

  • Multiple trials confirm that combination thermal and microneedling approaches outperform microneedling alone.


This evidence base supports RF Microneedling as more than a cosmetic trend — it is a medical procedure with documented biological effects.


Treatment Process


  1. Consultation

    • Assessment of skin condition, medical history, and suitability.

    • Discussion of expected results and treatment plan.

  2. Preparation

    • A topical anaesthetic is applied to reduce discomfort.

    • Skin is cleansed under sterile conditions.

  3. Procedure

    • Microneedling with simultaneous RF energy delivery.

    • Customised depth and energy settings for each facial zone.

  4. Aftercare

    • Mild redness and swelling for 24–48 hours.

    • Makeup is usually possible from the following day.

    • Sun protection and simple skincare are advised.


Downtime and Safety


Downtime is typically minimal:

  • Day 1–2: Redness and swelling

  • Day 3: Return to normal activities, with mild sensitivity

  • Week 1: Early tightening effects noticeable


Because medical-grade devices are used under clinical oversight, risks are low. Common side effects are temporary redness or swelling. Rare complications include infection or pigmentation change, but these are mitigated by strict sterile technique and professional assessment.


Number of Sessions Required


  • Standard protocol: 1-3 sessions, four to six weeks apart

  • Results timeline:

    • Immediate: a sensation of tighter skin

    • 2–4 weeks: smoother texture and reduced pore visibility

    • 12 weeks: peak collagen remodelling and tightening

  • Maintenance: One session every 12–18 months is recommended


Cost and Payment Options


At Rosem Health, each session costs £285.

To make treatment more accessible, we offer monthly payment plans at 0% interest. This allows patients to begin their course without delaying results.
