Keloids, also known as keloids or overgrown scars, are abnormal scar tissues that form after skin injury. They are not limited to the wound area but can spread beyond the original wound into the surrounding normal skin. This spread is due to the excessive proliferation of fibroblasts, leading to abnormal deposition of collagen under the skin.
The spread of keloids is often related to genetic factors, skin tension, the severity of trauma, and an individual's healing response. For example, keloids may be more common in areas of the body that experience greater tension, such as the shoulders, chest, or ears. Improper wound care, such as repeated friction or infection, can also promote the spread of keloids. Keloids typically present as hard, raised areas of skin, sometimes accompanied by pain or itching.
The spread of keloids is not a simple healing process, but a complex biological response. If a keloid grows rapidly, or if symptoms such as redness, swelling, or increased pain occur, you should seek medical attention immediately, as this may be a sign of infection or other complications. Many people mistakenly believe that all scars will flatten and become less noticeable over time, but in reality, keloids can continue to grow and even spread with slight irritation. Timely consultation with a dermatologist is crucial for the management of keloids.
[Prevention Tips:]
1. Avoid causing trauma to areas with high skin tension, such as the shoulders and chest.
2. During the wound healing process, keep the wound clean to avoid infection.
3. For existing keloids, observe their changes regularly and seek professional medical advice in a timely manner.
