Radiofrequency (RF) microneedling is a minimally invasive cosmetic procedure that involves the use of small needles that puncture the skin to deliver RF energy deep into the dermis. This procedure can be performed using either monopolar or bipolar RF modes. While both types of RF microneedling are effective in improving the appearance of the skin, there are some key differences between the two:
Monopolar mode employs a single electrode (active pole) tip that delivers energy between the electrode and a grounding pad, while bipolar mode transmits energy between two electrodes (active poles) applied to the skin.
Greater Depth of Penetration: Monopolar RF microneedling penetrates deeper into the skin than bipolar RF microneedling. This means that it can be more effective at treating deeper wrinkles and more severe skin laxity.
More Intense Heat: Monopolar RF microneedling can deliver more intense heat to the skin, which can result in much greater efficacy than Bipolar modality by treating a greater volume of the upper dermis resulting in more fibroblast activity.
Treatment Sessions Required: Because of its ability to deliver more intense heat, and penetrate deeper into the skin, Monopolar RF microneedling may require fewer treatment sessions than Bipolar RF microneedling to achieve the desired results with greater comfort and less bleeding.
Downtime: Overall RF microneedling is a minimally invasive procedure that typically requires little to no downtime. Patients may experience minimal swelling, redness, or discomfort that typically resolves within a few days.
Ultimately, the choice between Monopolar and Bipolar RF microneedling will depend on the individual needs and goals of the patient, as well as the expertise of the practitioner performing the procedure. It is important to consult with a qualified cosmetic dermatologist or plastic surgeon to determine which type of RF microneedling is best suited for your unique needs.
