Patients with a known predisposition should avoid unnecessary trauma or surgery, e.g. ear piercing, elective mole removal, etc. In these cases, it would be wise to treat any skin problems, such as infections and acne, as early as possible to minimize areas of inflammation.
Prevention of keloids after trauma or surgery
After surgery, the most effective preventions against keloids are an intact and smooth wound healing as well as a professional wound treatment. In addition, the fresh scar should not be exposed to too many ultraviolet (UV) rays. Sun exposure or tanning may discolor the scar, making it a bit darker than the other skin. Therefore, it is better to keep the scar covered during sun bathing or sport activities. Applying pressure and friction on fresh scars should also be avoided. If the scar is kept supple, the growth of new scar tissue can be prevented. Some doctors recommend special plasters, others suggest taking vitamin C to prevent the formation of keloids.
Removal of keloids
If the keloids are on plainly visible body parts or cause discomfort, they can be removed. However, surgery is not always needed. A keloid lying on the skin surface e.g. can be treated with medication or ointments. Another possibility to remove the scar is the application of “cryotechnology” based on the use of very low temperatures to prevent cell growth. Furthermore, cortisone injections reduce the visibility of keloids. Laser treatment of scars with fractional and ultrapulse CO2 laser belongs to the most modern methods in dermatology. The surgical correction of keloids by post-operation might be another option to remove the scar. However, some doctors warn this may result in the development of another keloid.
