The skin consists of the epidermis and the dermis. The dermis is the deeper of the two layers and any injury here be it traumatic or surgical will result in scarring. New scars are usually red and can be raised. Over a period of 12 months, the scar matures, flattens and loses its redness. Occasionally ‘bad’ scars can form which are lumpy, itchy and painful.
There are two types of ‘bad’ scars that can form :
A keloid scar is a lumpy, red and itchy scar which can extend beyond the initial injury. It more commonly occurs in asian and afro-carribean skin although it can also occur in caucasian skin. They also occur more commonly in certain areas such as the central chest, the shoulders and the ears. Keloid scars are notoriously difficult to treat due to their propensity to recur.
A hypertrophic scar occurs more commonly than a keloid scar. They are usually red, lumpy and itchy too but do not extend beyond the initial injury. The majority of hypertrophic scars resolve conservatively over time however in some cases, they require treatment.
Treatment Options :
Silicone tape or silicone gel can be effective when used on hypertrophic scars however they need to be used consistently over a minimum period of at least six months for any appreciable improvement
