Can I improve loose skin with Derma Rolling/ Micro Needling? (photos)

I have loose skin from a result of a weightloss. I have many stretchmarks alone the whole lower stomach and a lot on my sides as well. As you can see, i filled out pretty well, with more exercise to come. Do you think Dermarolling / micro needling all of these sides, along with using Retivol, aloe vera, and other creams, will improve loose skin and stretchmarks after a year of constant and careful use? I feel i have hope that this could be improved. Thank you
