Dermarolling / Microneedling / Can often-used 2 mm needles cause permanent damage to facial skin?
« on: April 17, 2013, 07:29:42 PM »I used the 2.0 on my chin acne scars which was a great help. I didn't realize till now that I shouldn't of used it on my entire face. I used it 3-4 times over a 4-5 month period. Did I do permanent damage?
Thank you
