In trying to read what would be the optimum depth for microneedling the scalp, depending on which report I read, they all have different recommendations. I've seen some that state .6-.75 is best. Others think between 1-1.5 is best, while others think it should be between 1.5-2.5. I realize that some studies are referring to a dermaroller but I'm specifically interested in the microneedling pen devices. Does anyone here have clarity on this topic?
