I got laser mole removal last year and it didn’t seem to work, would it be safe to re laser the area? (photo)

I got laser mole removal last year and it didn’t seem to work. When it was first done it was very bruised and was dark for ages and has only started to fade now. However it is very punish in colour and there is still some pigmarnt left underneath. Would it be safe to re laser the area or is there another course of action I could take as I am unhappy with the results
