What do keloid scars look like? Investigation of recurrence rates among earlobe keloids utilizing various postoperative therapeutic modalities. However, topical application to superficial wounds may be helpful.

Steroid Injections

It is an abnormal type of wound healing, which results in a large, soft growth where the skin has been damaged. Does it help reduce scarring? A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Repeated at intervals of weeks for developing keloids until it is stabilized or monthly for months on existing ones. If ears are pierced despite this advice, pressure earrings are commercially available for reducing keloid risk. To perform the procedure, a dermatologist first injects a local anesthetic into the areas of skin being treated.

Corticosteroid injections directly into the scar are often the first treatment used for keloids. Injections are used rather than topical forms of corticosteroids because the tissue cannot absorb the medication through the skin well enough to be effective in most situations. However, topical application to superficial wounds may be helpful. The larger doses are usually used on bulky, mature keloids.

Steroid injections are often used in combination with other types of treatment, including surgery. The shots are given before or after the other treatment, depending on the type.

With cryotherapy they are given first to soften the scar tissue and make it more receptive to the cryotherapy, while with surgery the shots are given afterwards. Some experts advise that steroid injections not be given until after sutures are removed to avoid risk of reopening the wound.

Corticosteroids reduce the production of collagen and proteins that form fibrous scar tissue as well as inhibit inflammatory factors. Studies of African people have shown that out of a hundred develop keloids. Half of people with keloids will have other members of the family who have also developed keloids.

Science hasn't yet managed to explain why some people go on to develop keloid scars after their skin is damaged, and others don't. But we have a pretty good idea of how it happens. Keloid scars are an overgrowth of skin after a cut or injury.

They can also occur after surgery, done by doctors - for example, after ear reduction surgery where there is a scar behind the ears or for removal of a suspicious skin growth. 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, and painful or produce a burning sensation.

Sometimes keloid develops without any apparent skin injury, although most people can identify a cause. Growth continues for a few weeks to a few months. The growth is usually slow but occasionally there is rapid enlargement over a few months.

Once they stop growing most keloid scars remain the same size or get smaller. Keloid growing over a joint can restrict movement. In time, the original red colour changes to brown or becomes pale. This image shows a keloid scar on a 4-year-old child's toes, that formed following surgery he had at the age of 2 years:. Many patients ask for their keloid scar to be 'cut out' surgically excised. This is hardly ever successful and in fact can result in an even bigger keloid scar coming back.

Keloids must never be cut out by a GP or by anyone who isn't medically qualified. They should only be treated by a specialist doctor such as a dermatologist or a plastic surgeon. Even then, most doctors will be very guarded in what they promise: This image shows a keloid around a Caribbean woman's ear that came back after surgery a and b , followed by repeat surgery c and then repeated steroid injections d:.

Once someone has had a keloid scar, it is vital they avoid piercings, tattoos and ideally any surgery unless essential. A variety of topical silicone products, which are available without a prescription, may reduce the size and color of scars. When applied to the scar, silicone attaches to the tissue at the molecular level.

It is thought that by creating tension on the surface of the skin, silicone can prompt the body to shrink excess collagen and repair broken blood vessels, which cause scars to look red and swollen. Topical silicone products are available as gels, as well as adhesive sheets that have a layer of silicone gel on one side and fabric backing on the other. Topical silicone products can be applied to scars that are still pink and healing, as well as older scars, including small hypertrophic scars and small keloids.

These products are safe for people of any age and skin tone. When a silicone-based product is applied and left on the skin for 12 hours or more per day, many people see results within two to four months, although the time frame varies from person to person. Our dermatologists determine how often you should apply the topical silicone and how long to continue treatment based on the size and location of the scar, the cause of the skin wound, and the type of scar.

Additionally, there is a new silicone surgical dressing that is designed to take tension off the wound itself and may minimize postsurgical scarring. Dermatologists may inject a corticosteroid solution directly into a hypertrophic scar or keloid, which may help reduce its size. Steroids break the bonds between collagen fibers, which reduces the amount of scar tissue beneath the skin. Steroids also have powerful anti-inflammatory properties, which can help reduce swelling, redness, itching, or tenderness.

If you have a history of hypertrophic scars or keloids and require surgery, a doctor may inject steroids into the area before surgery begins. Surgeons may administer an additional steroid injection during surgery as well. If a hypertrophic scar or keloid develops after surgery, dermatologists recommend getting steroid injections every four to six weeks, limiting the total number of injections to five.

The procedure takes about 15 minutes, and often no anesthesia is required. In the hours after an injection, you can break up scar tissue yourself and improve the effectiveness of the injections by gently massaging the scar. Side effects may include thinning or sunken skin at the site of injection. Superficial external beam radiotherapy is a low-dose radiation treatment that uses highly focused beams of light called superficial X-rays to destroy collagen-producing cells and limit the growth of new ones.

Dermatologists may recommend radiotherapy if a keloid does not respond to steroid injections and topical silicone treatment, or if the keloid is particularly large. Radiotherapy is a painless process. Depending on the location of the keloid, you sit or lie down on an exam table.

A radiation therapist covers the surrounding skin with a lead apron to protect it from radiation, then positions the radiotherapy machine so that it rests directly on the keloid.
