There can be a number of problems with scars on the skin. A keloid is an excessive production of scar tissue that can result from acne scarring, a surgical scar or from ear or body piercing. They are more common in darker skin types and certain areas of the body. Keloids can also be itchy or painful. There are a number of treatment options for a keloid scar which includes injections into the scar, laser or intense pulsed light therapy, topical treatment in the form of creams or occasionally re-excising the scar.
Traumatic scars can often be improved by scar revision surgery. This is because a neat surgical scar will heal better than tissue that has been injured, torn or crushed. Scars in some areas can undergo stretch and widen. Once again treatment options are sometimes available for this.
