Scaring can occur after there have been episodes of inflammation, infection or trauma to the skin. Common causes of scarring can include acne, surgery, accidental injury, burns, injections, skin infections such as the chicken pox, piercing and tattoos. When a wound heals abnormally its due excess scar tissue being produced. It is more then what’s required for the heal being produced. Keilod scars and Hypertorphic scars are two examples of this. Hypertrophic scars remain within site of initial injury and will get better with time. Keloid scarring however extends beyond the site of initial injury and can become quite large, painful and sometimes itchy. Atrophic scars are another form of scars that can be seen on the face and body and is often associated with acne scarring. Scarring is caused by a particular pattern of healing in previously injured skin. If the wound only involves the most superficial layers of the skin, it may heal without scarring. If it involves the deeper portion of the dermis the skin heals with scarring.
