Hello. Thank you for your message.
Keloids occur from the overgrowth of scar tissue. Symptoms occur at a site of previous skin injury. The symptoms of a keloid can include a localized area that is flesh-colored, pink, or red. A keloid scar is benign and not contagious, but sometimes accompanied by severe itchiness, pain, and changes in texture. In severe cases, it can affect the movement of skin.
Factors that increase your chance of keloids include:
African American, Asian, or Hispanic ethnicity
Between 10-30 years old
Deep skin wounds, such as those with burns or surgical scars
Scars from acne, vaccinations, or chickenpox
