Scars are formed as a consequent of tissue injury, repair and remodelling. When repair and remodelling goes wrong, abnormal and unsightly scars are formed. Keloids are due to the overzealous production of collagen in response to tissue injury. These collagens are arranged haphazardly into whorls.
HOW DOES KELOID LOOK LIKE?
Keloids are reddish to purplish elevated scars that feel firm and infiltrates to the surrounding, beyond the site of the initial injury. It is like a growth that enlarges to the surrounding. Often, it may have tiny extensions to the peripheries. Some keloids form a spherical nodule, i.e. over the ears. It is often confused with hypertrophic scar, which is also an elevated reddish scar. However, it does not penetrate or infiltrate the surrounding and remains confined to the site of injury.
DOES KELOID GO AWAY?
Keloids are very rarely to resolve by its own. On the other hand, hypertrophic scars may regress with time. Most of the time, keloids can continue to grow or remain static in size.
WHY DO I GET KELOID?
There are a few reasons why some people are more prone to keloids. It tends to run in the family. This means that if any of your blood-borne relatives has keloids, you have a higher risk of getting it.
Apart from that, there are areas on the body that are more prone for keloids, i.e. chest, shoulder, chin and ears.
IT’S JUST A SCAR, WHY DO I BOTHER?
It is does not bother you, you can just leave it alone. However, some keloids may itch or even causes pain. Occasionally some keloids may be infected and may even ulcerate. When it causes problems, it is best to treat it.
KENOCORT (TRIAMCINOLONE) INJECTIONS
These are safe and not very painful. Injections are usually given once every 4 weeks until the keloid is flat. The injection is mixed with a local anaesthetic medicine called lidocaine to make it numb and less painful to inject. You may need 3 or 4 sessions to make it more flat. Some people may need even more injections, depending on their genetics, how well the respond to the injections and the size of the keloid. The injections may cause redness, swelling or sometimes scabbing for a few days. Kenocort injections will make the keloid flat, but it cannot remove the colour of the keloid. The colour can be removed using Medlite Laser.
