Which demographic group is most commonly affected by keloids?

Keloids are an overgrowth of scar tissue that can form after injury or surgery, and they are most commonly found in individuals with darker skin types, such as those of African, Hispanic, or Asian descent. The reason for this increased prevalence is thought to be related to genetic factors, skin pigmentation, and differences in wound healing processes among different racial and ethnic groups.

Darker-skinned individuals often have a higher prevalence of keloid formation due to potentially greater collagen production in response to skin injuries. This can lead to more pronounced scarring than seen in lighter-skinned individuals. The condition is less commonly found in lighter-skinned individuals, who appear to be less susceptible to developing keloids.

Additionally, keloids typically do not affect children exclusively; although they can occur in any age group, the highest incidence is seen in individuals aged 10 to 30 years. This further emphasizes that keloids are not limited to any specific demographic age group. Thus, darker-skinned individuals represent the most affected demographic group regarding keloid formation.
