I have a lot of eczema scars on my back, but the eczema still comes and goes. Is Dermarolling right for me? (photo)

Im 22 years old and have been dealing with eczema for 6 years. It pops up in various places on my body but the place that gets it the most is my middle back. I use Aveeno eczema care lotion and Dove sensitive skin beauty bar. When the eczema is active, I use a prescribed steroid cream. After a flare up, the scars are intense and I hate showing my back. The picture is current, I haven't had a flare up in about a month. Could a personal dermaroller help?
