Does Dermaroller Work for Deep Acne Scars?

For pits, Dermapen works beautifully.  For ice pick like scars, I prefer to excise those. 

Dermaroller may blunt the edges of deep scars, but probably will not get rid of them. Dermaroller is more effective on milder or shallower scars.

Deep acne scars may require filler to "fill them in". Results last for a few months. You can try microneedeling, however it may not achieve the results you want as deep scars tend to require something a little more invasive.

Abhi,The Dermapen, a type of dermaroller we use in our office, is not ideal for deep acne scars. Dermapen and dermarolling in general work well for acne scars that are superficial and still require multiple treatments. I will usually excise the deep acne scars and then offer my patients dermabrasion to improve the appearance of the scar. In darker skin types, dermabrasion is not an option but Dermapen or dermarolling is and can help with improving the appearance of shallow or superficial scars after the deeper scars are addressed. Much of it also has to do with postoperative care and acne control.

Very deep acne scars can be improved by a derm roller but not eliminated completely. Depending on the level of the scar it may require C02 laser ablation to correct. Generally for acne scars a combination approach is necessary and no one single approach works all the time. For single, deeper scars a punch excision or punch graft may be the better option.
