WebMD lists the following three types of scars:
These scars are the result of an overly aggressive healing process. They extend beyond the original injury. Over time, a
keloid scar may hamper movement. Treatments include surgery to remove
the scar, steroid injections, or silicone sheets to flatten the scar.
Smaller keloids can be treated using cryotherapy (freezing therapy
using liquid nitrogen). You can also prevent keloid formation by using
pressure treatment or gel pads with silicone when you are injured.
Keloid scars are most common among people with dark skin.
If your skin has been burned, you may have a contracture scar. These scars tighten skin, which can impair your
ability to move. Contracture scars may also go deeper, affecting
muscles and nerves.
These are raised, red scars
that are similar to keloids but do not go beyond the boundary of the
injury. Treatments include injections of steroids to reduce
inflammation or silicone sheets, which flatten the scar.
(Emphasis mine, I also omitted acne scars on purpose.)
You seem to either have scars of type I or III.
The first step to take would indeed be to talk to a dermatologist. They will diagnose the scar and possible removal options.
Later on, you might be lead to visit a cosmetic surgeon for the scar removal, or there will be steroid injections.
