Know the cost vs benefit
If you thought you were shelling out some dineros to get your tattoo, that was nothing compared to how much it will cost to remove it.
Dermabrasion is less expensive than laser and a lot quicker, but it pretty much comes with a guarantee of scarring, and it could cause infection or permanent discoloration. It's also the most painful option.
Excision is also cheaper than laser removal, and it's a good option if you want to get it over with quickly, and you don't mind a small scar. You'll be under the knife, but it's generally an outpatient procedure performed with a local anesthetic.
