Understanding Monopolar RF vs. Bipolar RF vs. RF Microneedling

Written by Cartessa Aesthetics | Jan 21, 2025 3:25:45 PM

Radio frequency (RF) technology has revolutionized non-invasive skin treatments, offering patients remarkable results without surgery or extended downtime. 

When evaluating treatment options, understanding the differences between modalities can help practitioners choose the right technology for their practices.

Drawing on our commitment to identifying transformative aesthetic solutions, Cartessa Aesthetics offers EVERESSE, a technology that meets the growing patient demand for comfortable, natural-looking results. This innovative approach to RF treatments aligns with the needs of today's aesthetic practices, offering enhanced clinical capabilities while supporting long-term practice growth.

Key Takeaways

  • RF Technology Overview: Monopolar RF offers the deepest penetration for lifting/volumizing, bipolar RF provides gentle superficial treatments, and RF microneedling enables precise depth control for textural concerns.
  • Latest Innovations: Water-cooling systems used by EVERESSE (vs. traditional gas cooling) have revolutionized patient comfort while maintaining optimal energy delivery to target tissue.
  • Treatment Efficiency: Newer monopolar RF systems such as EVERESSE can complete full-face treatments in under 30 minutes.
  • Versatility: RF treatments complement other aesthetic procedures, including laser resurfacing, HIFU, injectables, and collagen stimulators.
  • Patient Experience: Non-invasive RF treatments align with growing patient demand for natural-looking results with minimal to no downtime.
  • Practice Integration: The choice of RF technology should align with patient demographics, desired outcomes, and existing treatment offerings.

How Does Monopolar RF Work?

Monopolar RF (MRF) represents the gold standard in non-invasive skin treatments, particularly for facial lifting and rejuvenation. 

Mode of Action

MRF technology uses a single electrode to deliver electrical energy deep into the skin. A grounding pad completes the circuit, and the 6.78MHz frequency on the EVERESSE device is optimal for skin treatments, enabling the energy to penetrate deeply into the dermis, where it converts to heat.

Benefits of MRF

The ability to deliver energy throughout the papillary and reticular dermis layers makes MRF particularly effective. Another benefit of MRF is that it triggers a dual-phase response; initially, the heat triggers collagen fiber contraction, resulting in visible skin tightening. Over time, fibroblasts are activated, supporting collagen remodeling and regeneration as a mechanism of action.

Combined, these phases deliver immediate lifting and tightening and long-term restoration of youthful facial volume and contours, presenting patients with a holistic and transformative approach to skin revitalization.

Additionally, by targeting deeper tissue layers, monopolar RF nicely complements laser resurfacing treatments, which focus on surface-level concerns, offering practitioners a comprehensive approach to facial rejuvenation.

MRF technology excels at:

  • Deep tissue heating for maximum collagen stimulation
  • Comprehensive facial lifting and volumizing
  • Long-lasting results with continued improvement over time
  • Treatment of larger areas in a single session
  • Shorter downtime and less discomfort than other RF treatments 

EVERESSE: Innovation in Monopolar RF Technology

EVERESSE represents a significant advancement in MRF technology through several key innovations:

  • Continuous water-cooling system (versus traditional gas cooling) ensures stable epidermal temperatures while maximizing energy delivery.
  • Curved and tilted tip head enables complete coverage of facial contours, eliminating the missed areas common with traditional flat tips while minimizing energy concentration at the edges of the tip. 
  • Two ergonomic handpieces reduce operator fatigue and enable faster treatment times compared to single-handpiece systems.
  • EVERESSE tips have no time-lock restrictions, unlike competitors' tips that shut down after 2-4 hours regardless of shots remaining.

This precision enables optimal thermal effects and collagen stimulation without compromising patient comfort or safety.

 

Bipolar & Multipolar RF

Bipolar RF operates with two electrodes positioned close together on the skin's surface, resulting in a shallower depth of energy penetration.

The electrical current flows between these electrodes, creating a more targeted treatment area. While this can benefit specific concerns, the penetration depth is limited compared to MRF.

Multipolar RF systems use multiple electrodes to create several electrical current pathways. This approach is:

  • Designed for more precise superficial heating
  • Better suited for delicate areas
  • Typically gentler with less sensation
  • Good for maintenance treatments

RF Microneedling: A Different Approach

RF microneedling combines traditional microneedling with radio frequency energy delivery to affect both skin tightening and texture. This technology uses fine needles to deliver RF energy directly into the dermis at precisely controlled depths. 

Leading platforms such as VirtueRF have advanced this technology by optimizing thermal zone penetration beyond the reach of the needles, enhancing elastin and fibroblast activity for improved collagen production.

Distinct from non-invasive RF treatments, RF microneedling offers:

  • Direct delivery of RF energy to specific skin layers 
  • Enhanced skin tightening through controlled micro-injury
  • Effectiveness for texture concerns and acne scarring

However, RF microneedling may not be suitable for all patients. For example, those who are needle-averse or prefer a completely non-invasive option might find MRF treatments more appealing. Additionally, RF microneedling typically requires numbing due to the use of needles and is associated with more downtime, as the micro-injuries need time to heal.

 

Enhancing Practice Capabilities with Monopolar RF

For practices looking to expand their non-invasive treatment options, MRF technology offers several compelling benefits:

Clinical Efficacy

New MRF systems, such as EVERESSE, have overcome historical limitations through technological innovations:

  • Continuous water cooling systems that eliminate patient discomfort
  • Precision energy delivery that prevents hot spots
  • Real-time contact detection for consistent & safe energy delivery
  • Treatment times under 30 minutes for a full face and neck 

Versatility

Monopolar RF can be effectively combined with other treatments, including:

  • Laser resurfacing, such as Tetra PRO and HELIX
  • HIFU devices
  • Injectables
  • Skin boosters
  • Collagen stimulators

Patient Satisfaction

Today's patients increasingly seek non-invasive alternatives to surgery. MRF meets this demand by offering:

  • No downtime
  • Comfortable treatment experience
  • Natural-looking results
  • Progressive improvement over time

Choosing the Right Technology

When evaluating RF technologies, consider:

  1. Your patient demographics and their primary concerns
  2. The types of results you aim to achieve
  3. Treatment efficiency and ROI
  4. Compatibility with your existing treatment offerings
