Which Fitzpatrick skin type is most likely to develop a keloid scar?

Fitzpatrick skin types are a classification system that categorizes skin based on its response to ultraviolet (UV) light, as well as characteristics such as skin color and hair color. Keloids are raised scars that form due to an overproduction of collagen during the healing process. Individuals with darker skin types, particularly those classified as Type V and Type VI, have a higher propensity for developing keloids after injury or surgical procedures.

Type VI skin, characterized by deeply pigmented skin, is especially prone to keloid formation. The reasons for this include genetic factors, as individuals with darker skin often have a higher density of fibroblasts (cells responsible for collagen production), leading to a greater likelihood of excessive collagen deposition in response to trauma.

In contrast, Type III, Type IV, and Type V skin types have varying risks of keloid formation, but they do not exhibit the same pronounced tendency as Type VI. Therefore, Type VI is recognized as the skin type with the highest risk for developing keloids, making it the correct answer to this question.
