I’ve been recommending the derma roller for patients coming in for Cosmetic Acupuncture for years. This is a great summary of how it works. I can’t comment on the LED treatment that she combines with it, nor using lidocaine gel. Typically, the derma roller can be used at home and isn’t painful.
The advantage of cosmetic acupuncture in addition to the derma roller is that it keeps you on the regimen, plus you get the benefits of frequent acupuncture treatments. Better than laser for sure!
