Genius RF Microneedling & SkinPen

Skin Rejuvenation Clinic Minneapolis offers two complementary microneedling platforms: Genius RF microneedling and SkinPen. Genius RF delivers radiofrequency energy directly into the dermis through insulated microneedles at precise depth settings, combining collagen-induction needling with immediate RF heating for enhanced skin tightening and scar remodelling. SkinPen, the first FDA-cleared microneedling device, provides mechanical collagen induction for fine lines, acne scars, pore size, and uneven tone. Both treatments stimulate the skin's natural repair cascade, with a course of three to six sessions recommended for optimal results.

Skin Rejuvenation Clinic in Edina, MN employs two distinct microneedling technologies, each suited to different patient profiles and clinical goals, under the supervision of Drs. Mark and Beth Hagberg. Genius RF Microneedling is a radiofrequency-assisted microneedling device that uses insulated gold-coated microneedles to penetrate the dermis at clinician-selected depths — typically 1.5 mm to 3.5 mm depending on the treatment zone — before discharging bipolar radiofrequency energy at the precise needle tip depth. The insulation ensures RF energy is deposited specifically at the dermis level rather than heating the overlying epidermis, producing controlled thermal injury in the collagen-rich papillary and upper reticular dermis without surface ablation. This dual-mechanism approach — mechanical microinjury from the needles combined with volumetric heating from the RF — triggers a compound wound-healing response: immediate needle-tract inflammation recruits fibroblasts and macrophages; the RF-generated heat zone (typically 60–70°C for collagen denaturation and contraction) creates an additional thermal stimulus for neocollagenesis and elastin remodelling. The net result is progressive skin tightening, reduction of static wrinkles and rhytids, improvement of acne and surgical scars through extracellular matrix remodelling, and refinement of pore size. Genius RF is particularly suited to patients with mild to moderate skin laxity on the lower face, neck, and jowls who seek skin-tightening benefits without the recovery of ablative procedures. SkinPen is the first microneedling device to receive FDA 510(k) clearance, providing a clinically validated platform for purely mechanical collagen induction therapy. The motorised pen delivers sterile single-use needle cartridges at adjustable depth settings from 0.25 mm to 2.5 mm and at variable oscillation speeds, creating an even array of micro-channels across the treatment surface. The micro-injury cascade releases platelet-derived growth factor, TGF-β, and epidermal growth factor, stimulating fibroblast proliferation and new collagen and elastin synthesis in the remodelling phase over four to six weeks post-treatment. SkinPen is indicated for atrophic acne scars, fine surface lines, rough texture, enlarged pores, and diffuse photodamage, and its gentle thermal profile makes it appropriate for a wider Fitzpatrick range than RF-based or ablative modalities. A course of three to six monthly sessions is recommended for both platforms. PRF (platelet-rich fibrin) prepared from the patient's own blood can be incorporated into either treatment as an add-on, delivering an autologous growth factor concentrate through the open microchannels at the time of treatment.
