RF microneedle. Why do doctors prefer insulated over non insulated?

Non-insulated creates heat along the entire length of the needle and gives better results. I always combine microneedling with prp and lasers to get the best outcomes. See an expert. Best, Dr. Emer

Insulated needles allow targeting of the deeper dermis for tightening benefits.  For more superficial complaints such as fine lines and shallow acne scars, non-insulated needles would be more beneficial.  Although RF energy is safer in patients of color compared to lasers, any significant heat can result in increased risk of post-inflammatory hyperpigmentation.  Consult with a board-certified and experienced cosmetic physician.

The RF (Radiofrequency) Microneedling devices may offer the option of use of non-insulated needles vs insulated needles. With the Vivace RF Microneedling device, the insulated needles only deliver energy along the bottom .4 mm of the needle, protecting the epidermis. This allows the procedure to be performed on darker skin which is at a higher risk for hyperpigmentation.  The non-insulated needles deliver RF along the full length of the needles. They are used for lighter skin types.
