Keloid hyperplasia, also known as keloid, is basically unable to disappear on its own after formation. Keloid hyperplasia is mainly caused by local trauma, surgery, inflammation, etc. However, some patients can also develop local tissue proliferation without obvious triggering factors, causing raised patches on the skin surface. Keloid hyperplasia occurs mainly on the basis of keloidism, but there is no effective way to improve this condition. After the formation of an aesthetically disfiguring scar, the only way to achieve maximum results is through comprehensive treatment. Commonly used treatments in the clinic include medication, surgical excision, laser therapy, radiation therapy, and compression therapy, with targeted treatment plans for different individuals. Therefore, after an injury to a keloid, if the possibility of scarring is anticipated, preventive measures need to be actively taken. Such as reducing local exercise, using drugs that inhibit scar growth, as well as providing effective sun protection and preventing wound infection.
