How deep should Microneedling/Dermapen go for acne scars?

Question

I hope Dr. David Lim or any doctors can answer this. I'm a big fan of his Youtube Page. How deep should Microneedling go(in mm) in order for it to work on acne scars? My doctor only did 0.5mm and there was no difference.

Jason Emer, MD · Answer

Microneedling depth has not been studied.  I do on my self 0.5-0.75mm every few weeks and my skin looks amazing. Post laser I do microneedling and am more conservative than when someone comes in for a monthly or few times a year treatment.  It all is based on the condition being treated, the persons willingness for downtime and what their skin type is like. This should be evaluated and discussed by a cosmetic dermatologist for your long term goals. If you combine with lasers you use less.  Most scars require at least 1mm+. Best, Dr. Emer

Fractional treatments work well on acne scars. The dermaroller should at least go down to the papillary dermis, but the depth depends on your skin thickness. Best, Dr. KaramanoukianLos Angeles

Typically when using an automated microneedling pen such as dermapen or micropen device,  acne scars are treated with depths ranging from 1.5mm to 2.5mm and targeted using a stamp technique.   Treatment depth also depends on the skin area which are different for the forehead, cheeks , under eyes, etc.  Routine use when not used for scars typically ranges from 0.25mm to 1.25mm

Superficial scars only need 0.5 mm, deep fibrosis needs 3.5 or more mm . Really depends on the scar thickness. Touch and visual clues are important to determine  what is the optimal depth. Davin Lm
