Elastin plays a crucial role in maintaining the skin's elasticity and resilience. It is a vital protein that forms elastic tissue, which allows the skin to stretch and return to its original shape. This property is particularly important for areas of the skin that undergo significant movement, such as around the joints or in facial expressions. Elastin helps ensure that the skin can accommodate dynamic changes without losing its structural integrity over time.

While elastin does contribute to the overall strength of the skin, this function is more accurately attributed to collagen, which provides structural support and tensile strength. The barrier function of the skin primarily involves lipids and other components in the epidermis, which protects against environmental aggressors. Temperature regulation is managed by various physiological processes including blood flow and sweat production, rather than by elastin. Thus, the primary and most significant role of elastin centers on the formation and maintenance of elastic tissue, allowing the skin to be both flexible and resilient.
