Can Raised Tattoo Be Removed?

You should be examined in consultation to determine if the raised texture is an unusual allergic reaction to the pigment, or if you are producing more collagen in the dermis as a reaction to the trauma of the tattoo needle. The latter might be called either a hypertrophic scar, if the thickening is limited to the shape of the tattoo design, or a keloid, if the thickening spreads out beyond the design.

Both allergic reactions to pigment and overhealing scars can be treated by injecting the area with corticosteroids. The risk of these injections is the possibility of developing over thinning, or atrophic depressions in the skin's contour, as well as lighter skin color, and the development of fine blood vessels, or capillaries in the skin where the injection was given.

Surgical removal, or excision, of tattoos will leave a scar, and it can be unsightly if a keloid forms after the surgical excision.

Some patients have obtained benefit by laser therapy of hypertrophic scars, and some scars have improved from injections of medicines including: 5-fluorouracil, interferon, and the topical use of Aldara. and corticosteroid adhesive tape.

The raised skin is a scar. These scars are caused by excessive tissue formation. The dermatologist who removed the tattoo should see it and suggest treatment.

Raised scars indicate that you may have keloid or hypertrophic scarring tendencies.
These can be very difficult to treat although there are options.
There are two issues here:

Pigment removal
scar management

The problem is that pigment removal can trigger more scar tissue formation. I would first recommend trying a test area with laser removal followed by scar managment with pressure or laser or intalesional injections may be an approach to your problem.
