What is defined as an overgrowth of scar tissue?

A keloid is defined as an overgrowth of scar tissue that forms at the site of a healed skin injury. It occurs when the body produces excess collagen during the healing process. Unlike regular scars, keloids can be raised, larger than the original wound, and may continue to grow beyond the wound's boundaries. They can also vary in color, texture, and size, often appearing shiny or smooth. This condition is most commonly found in individuals with darker skin tones and can be triggered by surgical scars, acne, or even minor injuries.

Understanding keloids is important for nail technicians and those in the beauty industry because they can affect the appearance of the skin. Additionally, knowledge of keloids helps in recognizing conditions that may require special care or treatment when providing services, ensuring the safety and satisfaction of clients.
