Depending on the size of a keloid scar, the treatment options can include cryotherapy, application of silicone sheets, steroid injections, laser and surgery, as noted by the United States National Institutes of Health's MedlinePlus. A keloid is an overgrowth of scar tissue that is a raised and shiny area, which may also range in color from pink to red. Keloid scars tend to develop in people with dark skin.
Some causes for keloid scars are skin injuries that can result from cuts, burns and acne, When keloid scars are small, a treatment option can be cryotherapy. The procedure involves freezing the affected area with liquid nitrogen to remove scar tissue, as noted by WebMD. Another method to reduce the keloid scar tissue is to use silicone gel sheets over the scar to flatten it out. The treatment can take a few months, bur results can vary in patients, as stated by MedicineNet.com.
The use of steroid injections into the scar tissue can help minimize the appearance of the scar, but it can cause the flattened scar tissue to become more red in color. However, with the use of laser treatments the redness can be reduced. For large keloid scars, surgery to excise the scar may be an option, but surgery can also cause the formation of a larger scar. Some other ways to treat keloid scars are with laser, radiation and interferon injections. Interferons are proteins manufactured by the body, which may help in the reduction of these scar types, as stated by MedicineNet.com.
