I have been getting microneedling treatments using the Rejuvapen at a medical spa. The aesthetician used a depth of only about 1.4mm for my first four sessions and went deeper at 2mm for my past two sessions and will continue at 2mm. I've seen some results but not nearly enough as I thought I should. My scars aren't that bad or deep. Is this possibly because I should be using a better device? Is there a real difference between the results based on the pen used?
