Detailed answer

Collagen is important in scar formation as it provides structure, strength, and support to the skin. When the skin is wounded, collagen fibers are produced to help repair and heal the damaged area. Initially, collagen is laid down in a haphazard manner, resulting in the formation of a temporary scar. Over time, the collagen fibers undergo remodeling to align more uniformly, forming a permanent scar. Imbalances in collagen production or degradation can lead to abnormal scarring such as hypertrophic or keloid scars. Thus, collagen plays a vital role in the entire process of scar formation.
