The earlobe is made of dense connective tissue rich in collagen and elastin, two key proteins that give skin its firmness and flexibility. In youth, collagen is tightly packed, forming a stable structure, while elastin gives the earlobe the ability to bounce back after stretching.Over time, as with the rest of the face, the quantity and quality of these fibers decline. The tissue loses its support, elasticity weakens and the skin becomes thinner and looser. In addition to the natural aging process, sun exposure, smoking and the loss of subcutaneous fat all contribute. What was once a plump, firm lobe may become elongated, saggy and even wrinkled.
