Keloids are scars that are caused by increased tissue formation after some type of trauma to the skin has occurred. It usually carries a smooth top and a pink or purple color. Keloids are irregularly shaped and have a tendency to enlarge or grow progressively. Unlike the normal scars, keloids do not subside eventually. After the skin will be injured, the healing process usually leaves an apparent flat scar. Sometimes the scar tissue is hypertrophic or thickened but confined into the margin of the wound. Hypertrophic scars tend to become redder and may subside (a process that would often take one year or more). Treatments like cortisone (steroid) injection can speed up this process.
Keloids can start a whole after the injury and extend beyond the injured site. This has a tendency to migrate into surrounding areas that were not injured to start with and this is the distinguishing feature of keloid from hypertrophic scars. Keloid typically appears after injury or surgery, but they can furthermore appear spontaneously or from slight inflammation just like acne even if it was not scratched or otherwise irritated. Other minor injuries that may trigger keloids are piercings and burns.
Here are some keloid scar treatments:
Cortisone shots (intralesional steroids) – Most are safe and not extremely painful. Injections are typically given once on a monthly basis until the maximum benefit is obtained. Injections can normally help flatten keloids.
Surgery – This procedure can be risky because cutting a keloid can certainly trigger the formation of a similar or even greater keloid. Some surgeons would first inject steroids or apply pressure dressings towards the wound site after cutting away the keloid. Radiation after the surgical excision has also been used.
Laser – The pulsed-dye laser might be effective at flattening keloids and also making the keloid look less red. Treatment is normally safe and not that painful. However, several treatment sessions can be needed for better results. These may often be costly since such treatments usually are not generally covered by an insurance claims.
Silicone sheets – This method normally involves wearing a sheet of silicon gel on the affected area for several hours a day for couple of weeks or months which is hard to sustain.
Cryotherapy – This involves freezing the keloid with liquid nitrogen and then flattening them but this often darkens the treatment site.
These are just some ways for keloid scar treatment. The decision still depends on the person which treatment plan to undergo. It is often recommended to go and visit your doctor to know which treatment plan is good for you.
