Which protein provides the skin with strength and structure?

Collagen is the main structural protein in the skin’s dermal matrix, forming a fibrous network that provides tensile strength and helps the skin resist tearing. Elastin contributes elasticity, allowing skin to stretch and snap back, but it doesn’t provide the primary strength. Keratin is the key structural protein in the epidermis, hair, and nails, forming protective outer layers rather than the dermal framework. Melanin is pigment that protects against UV light, not a contributor to skin’s structural strength. So collagen best provides the skin with its strength and structure.
