Scaring occurs when the normal skin is replaced by fibrous tissue following an injury. It is the result of the body’s natural healing process to repair a wound to the skin. Most wounds, apart from very minor ones, result in a scar.
While scar tissue is composed of collagen protein, the same that forms normal skin, rather than the fibres being randomly orientated, they are cross linked and form in just one direction. Apart from the appearance of a scar, scar tissue is much weaker than normal skin, for instance it is more susceptible to ultraviolet radiation damage, sweat glands don’t re-grow in it, and it has no hair follicles.
There are a number of different types of scars: Keloid scars occur when the healing process is aggressive causing the scars to extend further than the injury and they can hamper movement, they may require surgical treatment or freezing. Contracture scars result from burns; they can make the skin very tight and impair movement. Hypertrophic scars are raised red scars that are restricted to the area of the injury. Acne scars can result from acne and can occur in different forms which include small deep holes, rolling scars, and oval depressions.
Treatments – there are a number of treatments that can reduce scarring. These include collagen injections, chemical exfoliation, laser treatments, and corticosteroid injections. Vitamin A Skin treatments can also help reduce the dark pigmentation and moisturising
