Is dermabrasion a good idea for my hopeless arms? (Photo)

I was having brown-colored acne blemish on my arms, later on I had a skin color tattoo done on the blemished area. But now also the tattoo looks so ugly and not natural, that was a bad idea. Laser leaves permanent scar spots on my skin, also. What can I do? Is dermabration a good idea you think? Please help me cope with this...
