Hypertrophic and Keloid scars are variations to the scars formed in the natural healing process. A hypertrophic scar is red, raised and thicker than a usual scar. Keloid scars are thicker and spread beyond the area of the initial wound.
The variations occur when there is an increase in collagen production and reduced scar breakdown, leading to excess scar formation. The formation of hypertrophic and keloid scars tend to be genetic.
It is important to monitor your scars, as early intervention and education can minimise their severity.
