C-SECTION SCAR appearance and adhesions will dermaroller help? (photo)

I delivered my second baby via c section 14 weeks ago, I've got a lot of adhesions throughout the scar (much worse on my right side), you can't pull the skin around at all, it's just 'stuck' in position), i'm wearing a silicone sheet as much as I can and massaging the scar also. Would it be safe at this stage to have dermaroller / skin needling treatment on it? Would this help with the adhesions as well as the appearance of the scar? Many thanks
