Microneedling RF options for patient with gold allergy?

Thermage® is a safe, non-invasive, radiofrequency (RF) cosmetic procedure that’s clinically proven to help smooth, tighten and contour skin for an overall younger looking appearance. The treatment delivers natural looking results with little to no downtime —on all skin colors, on and off the face, all in a single procedure. Fast and easy, you can even come in during your lunch break and return to work after! Thermage® uses radiofrequency technology to heat the deep, collagen rich layers of your skin. The heat helps tighten existing collagen and stimulate the formation of new collagen, which reduces sagging, renews contours, and improves the smoothness and texture of the skin’s surface. Comfort Pulse Technology, including a vibrating handpiece delivers enhanced patient comfort. Thermage® can treat wrinkled, sagging or bulging skin as well as the appearance of cellulite, including on thighs and knee area. While you will see an improvement immediately, Thermage® usually takes up to 6 months to see the maximum result and this improvement is said to last approximately 18 months. Often patients repeat Thermage® more often to get additional tightening. It's important, of course, to make sure you see a board certified plastic surgeon or dermatologist because results can be variable depending on who is performing the procedure.

Thank you for your inquiry. You could try a combined SkinPen treatment (contraindicated in those with a stainless steel allergy) with a FORMA treatment (by InMode Aesthetics). The SkinPen has a maximum depth of treatment of 2.5 mm and the FORMA handpiece delivers RF energy with no needles. However, since you mention only having "minor" laxity, you could also do an extended series of just FORMA treatments at the neck (but you might as well include the face too!) for the tightening effect. My advice is limited as there are no pics to adequately evaluate your neck concerns.
Best of luck!
