Scarhttps://en.wikipedia.org/wiki/Scar
Scar is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs, and tissues of the body. Thus, scarring is a natural part of the healing process. With the exception of very minor lesions, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring.

Treatment
Hypertrophic scars can improve with 5 to 10 intralesional steroid injections 1 month interval.

Laser treatment may be tried for erythema associated with scarring, but triamcinilone injections can also improve the erythema by flattening the scar.
