Can microneedling cause nerve damage?

Microneedling is a great option for any type of facial scar.  It can be used in all skin colors and skin types. The small needles cause new in juries in the skin and activate the healing process to make new skin.  The depth of needles depends on the depth of scar.  
Make sure you see a Board Certified Facial Plastic Surgeon to assess the need for deep treatment or superficial treatment.  Consider adding Platelet Rich Plasma to your treatment to activate more healing growth factors and greater collagen growth and scar remodeling.  

If performed correctly, microneedling should not cause nerve damage. I always combine microneedling with prp and lasers to get the best outcomes and this combination will give the most improvement to your scar. See an expert. Best, Dr. Emer

Microneedling is great for scars, fine lines, and collagen stimulation. The microneedling needles are not deep enough to reach your nerves. With that said I recommend you get microneedling by an experienced physician.
