A keloid is a type of overgrown scar tissue which results in a discolored raised lump on the skin. Acne is a common cause of keloid scarring in susceptible individuals. There are several different treatment options for keloid scarring caused by acne, although no particular treatment is conclusive. Your keloids may recur or regenerate following treatment.
MedLine Plus reports that certain individuals have greater susceptibility to developing keloids as a result of acne or other skin problems. Genetics can play a factor, with keloids sometimes running in families. Age, gender and ethnicity also play a part in determining the likelihood of keloid scars developing -- young women are the group most generally susceptible to keloids, and there is also an increased risk among people with African heritage.
Typically, a keloid forms when your body's scarring process over-reacts to a skin injury or condition. Any injury to the skin which would typically lead to the formation of regular scar tissue may trigger a keloid scar if you have the susceptibility. Acne is a common cause of keloid scarring, as the damage done to your skin by an acne episode may provoke keloid scar formation as the skin heals. Additionally, keloids are commonly formed as a result of surgery, chickenpox, burns, needle punctures, injury or wounds.
Although keloid scars may form unpredictably, the Mayo Clinic website reports that the risk of keloid scar formation can be reduced by taking care of your skin as well as possible. Don't pick or scratch your acne, as tearing of the skin can prompt a keloid scar. Keep your skin clean, dry and intact as possible.
There are several treatment options for existing keloid scars, although none are perfectly effective. Quite often, a keloid scar will disappear of its own accord, and will not need medical treatment. Persistent keloid scars may be treated with one of the following procedures: freezing, radiation, pressure, surgery, corticosteroid injections or laser therapy. Surgical treatment of keloids carries an inherent risk that the surgery itself may lead to the formation of more keloid scarring at the surgery location.
A report in the October-December 1999 issue of the journal "Archives of Facial Plastic Surgery" states that keloids caused by acne can be surgically excised or cut out . The study followed five individuals whose acne-induced keloids were infected and had a surface area larger than 10cm by 15cm. None of these five patients were reported to have experienced recurrence of their keloids, and the surgical wound typically healed within six to 10 weeks. The report recommends direct surgical excision as a surgical treatment for acne keloids, although it is noted that the cosmetic or visual results of the surgery were not always as good as could be hoped.
