Why would you even consider this? if the scar is "odd" or visible, your surgeon probably wants to revise it or laser it so it will disappear. Working precisely in the mirror with a microneedle can be difficult. Magnification, in my opinion, is essential. Even so, microneedle treatment generates collagen (scar) over time (repeated treatments). Will more collagen (scar) improve your appearance at the objectionable area?
