Which skin protein provides elasticity and resilience?

• A. Elastic Fibers
• B. Keratin
• C. Melanin
• D. Collagen

Answer: (A)

Elasticity and resilience in the skin come from elastic fibers. These fibers, containing elastin, allow the dermal tissue to stretch with facial movements and then snap back to its original shape, giving skin its rebound and adaptability. Keratin is the protective protein of the outer epidermis, not responsible for elasticity. Melanin is the pigment that determines color and UV protection. Collagen provides strength and structure, contributing to firmness but not much to elasticity. Understanding that elastic fibers drive the skin’s ability to rebound helps explain how the skin will respond to needle insertion and pigment deposition in PMU, especially in terms of how it moves and returns to shape.
