Wrinkles and facial lines, or rhytides, arise from several factors:

• Aging: Natural decline in dermal thickness and hydration.
• Sun Damage: Accelerates skin aging by breaking down collagen.
• Facial Movements: Repeated expressions cause fine lines that deepen over time.
• Skin Tension and Gravity: Contribute to the sagging and folding of the skin.
• Other Factors: Includes injuries, surgeries, acne, certain skin conditions like discoid lupus erythematosus, and smoking.

Skin laxity results from the loss of subcutaneous fat, collagen, and elastin, compounded by the effects of gravity. This leads to features like brow and eyelid ptosis, sagging eyelids, jowls, and other changes that give a tired and aged appearance.
