Detailed answer

Genetics play a role in determining an individual's skin pigmentation and response to injury, which can impact scar pigmentation. Variations in genes responsible for melanin production and distribution can affect how scars appear on the skin. Some individuals may have a genetic predisposition to develop hyperpigmentation or hypopigmentation in scars, meaning they may become darker or lighter than the surrounding skin. Additionally, genetic factors can influence the healing process and the amount of collagen production, which can also affect scar pigmentation. It's important to note that while genetics can contribute to scar pigmentation, other factors such as sun exposure, wound depth, and post-injury skincare practices also influence the final appearance of scars.
