Sometimes when wounds heal, they can form abnormal scars. These are known as keloid scars.
In addition to being an issue of esthetics, keloids can lead to other problems such as itchiness, burning or pain, which is why it is important to treat them.
As the EFE news agency explains, when a wound is healing, the skin uses certain mechanisms to close it. Included in these, is the production of collagen for the wound to heal. This collagen is made of cells called fibroblasts. With a keloid, these fibroblasts react abnormally and collagen is created out of control, forming incorrectly. “It’s like a tumor; the cells are out of control. They react as if there was an open wound and continue to form a scar,” Miguel Sánchez Viera says, Director of the Instituto Dermatológico Integral.
Keloids are difficult to prevent, as anatomical factors, genetic factors and ethnic background all play a role in their appearance. They are therefore not the result of the surgical technique that was used or of postoperative care. Gender and age also play an influence, as they commonly occur on women’s necklines and shoulders.
These scars react poorly to treatment, which is why it is important to try a combination of different alternatives over several different sessions. These alternatives include silicone-based products, medications that are injected directly into the scar and laser treatments.
