Keloids are distinctive types of scars that occur when scar tissue grows excessively. Unlike normal scars, keloids have a tendency to continue growing long after the initial injury and do not naturally fade away over time. These raised scars appear smooth on the surface and can vary in color, ranging from pink and red to purple. Although keloids can develop on any part of the body, they do not pose any significant health risks. However, many individuals find them bothersome due to itchiness, discomfort, and their overall impact on appearance.
Keloids: Understanding Raised Skin Growth
Keloids are an abnormal type of raised skin growth that can appear in various colors and textures. These claw-like masses can be skin-colored, pink, red, purple, or brown, forming smooth and hard growths. Depending on their size and location on the body, keloids may hinder movement. Interestingly, over 65 percent of keloids are found on the shoulder, chest, stomach, and earlobes. Furthermore, keloids occur 15 times more frequently in individuals with darker skin tones, such as those of African, Asian, and Latino descent, compared to Caucasian individuals of European descent. It is worth noting that the majority, approximately 80 percent, of keloid cases affect people under the age of 30.
Why Keloids Grow Larger Over Time
Unlike regular scars, keloids have the tendency to grow larger as time goes on. The exact cause of keloids is still uncertain, but experts believe that it may be related to changes in cell signals associated with cell growth and inflammation. In contrast to typical scars, keloids are unpredictable and can develop long after the initial injury. They can also arise from seemingly minor sources of inflammation, such as an acne pimple, a burn, or a piercing.
