Collagen is primarily found in the dermis, which is the deeper layer of the skin.
The dermis is the primary location of collagen within the skin, where it forms a structural network responsible for the skin's strength, elasticity, and overall integrity. Collagen constitutes a significant portion—at least 70%—of the dry weight of the dermis.
Types of Collagen in the Dermis
While many types of collagen exist, the two most prominent types found in the dermis are:
-
Type I Collagen: This is the major form of collagen in the dermis and provides significant tensile strength to the skin, allowing it to resist stretching and tearing.
-
Type III Collagen: While also present in adult skin, Type III collagen is more abundant in fetal skin. It contributes to the skin's overall structure and repair processes.
In summary, collagen, especially Type I and Type III, is predominantly located in the dermis, playing a crucial role in maintaining skin's structure and resilience.
