Keloid is a form of scarring. It may appear on skin as red, raised formation of fibrous scar tissue, caused by excessive collagen formation in the skin layer (dermis) during the process of connective tissue repair, after any trauma or injury to skin. Some people have a tendency to have keloid formation after any kind of skin injury.

Homeopathic medicines can partially reduce scarring if keloids are very mild. Moderate to severe keloids generally do not respond to homeopathy. Itching and painfulness can reduce with homeopathic medicines. Some cases of keloid tendency may be controlled with homeopathy to certain extent.
