A keloid is a special type of scar. All wounds heal with a scar but a keloid scar is one that grows too much and can even become larger than the original wound. It can occur after minor skin damage and involve the areas outside the scar itself. It may last permanently.
Risk factors include darker skin, young age, past history, wounds under tension. Common areas include upper chest, shoulders and earlobes.
Treatment is difficult and not always successful. Possible lines of treatments include the following:
Injections of a steroid (triamcinolone) into a keloid may help to flatten small and early ones.
Steroid-impregnated tape applied for 12 to 24 hours a day may help to flatten keloids.
Putting a silicone sheet over them at night for several months helps some keloids to flatten. Silicone in gel form is also available.
Laser treatment makes keloids less red but does not make them smaller.
Keloid treatment with intralesional steroid injection
This is a procedure involving the injection of a steroid solution into the abnormal skin, with the aim of improving its appearance or reducing symptoms such as itch or pain.
We perform intralesional injection of a steroid in the procedure room at Clinica London. No special preparation is required and a local anaesthetic is not needed. Depending on the size of the area to be treated, you may need several injections. There are some side effects to this type of therapy, which we discuss before the treatment.
