A keloid is a thickened scar that forms typically after injury to the skin.

Common causes of keloids

  • Acne

  • Surgery

  • Trauma

  • Burns

  • Insect bites

  • Ear piercing

  • Body piercing

A keloid projects beyond the margin of the intitial injury. In contrast, a hypertrophic scar is thickened but does not protrude beyond the margins of the initial injury. The difference is in the degree of thickening.

Treatment of keloids

In a study involving 224 patients who used silicone gel sheets for scars, significant improvement was seen in the colour, thickness and elasticity of hypertrophic (thick) scars and keloids (J Clin Aesthetic Derm 2016 Oct 9(10). 28-35)
