Keloid Scar Treatment
Keloid scars appear as a hard lump or growth in the skin. These scars are more severe and sensitive than hypertrophic scars. Keloid scars develop within scar tissue. During wound healing, the skin overcompensates and forms excessive amounts of collagen in the area. Keloid scars are difficult to treat since most cosmetic procedures induce a small injury to the skin in order to force the body to repair itself and produce new tissue. Stimulating this type of wound healing in the skin for those with keloid scars could make the scar appear worst than its original form due to the body's need to over heal the area.
Injection For Keloid Scars
At Bellair Laser Clinic we use steriod injections to treat keloid scars. When we inject a steroid injection into a keloid scar we are treating the keloid on many levels. Steroid injections work by preventing the rubbery material that makes up the cells of the keloid scar from producing collagen. As they weaken the scar they are also encouraging the keloid scar to flatten. Steriod injections also reduce the itchiness and tenderness of the scar if present.

Keloid Scar FAQs
Treatment intervals are 4-6 weeks apart.
Keloid typically starts to develop about three months after the original skin damage although it can take up to a year. The first thing you will probably notice is that rubbery scar tissue starts growing beyond the borders of the original damage. It may become tender, itchy, painful or produce a burning sensation. Sometimes keloid develops without any apparent skin injury, although most people can identify a cause. The common areas are the breastbone, shoulder, earlobe and cheek. Keloid growing over a joint can restrict movement. In time, the original red colour changes to brown or becomes pale.
Studies show that kenalog injections suppress inflammation and mitosis while increasing vasoconstriction in the scar. Triamcinolone acetonide suspension (Kenalog) 10 to 40 mg per mL (depending on the site) is injected intralesionally, which, although painful, will eventually flatten 50 to 100 percent of keloids, with a 9 to 50 percent recurrence rate.
Kenalog injections may decrease the risk of scarring but generally it does not prevent scars. Those who have severe acne are likely to develop scars post inflammation from acne.
