Wrinkles are natural signs of aging that result from decreased skin elasticity and collagen production over time, often appearing as fine lines and creases on the skin's surface. Wrinkles can be caused by a combination of factors, including the natural breakdown of collagen and elastin fibers in the skin, repeated facial expressions , exposure to ultraviolet radiation from sun, smoking, and genetics. Cosmetic procedures such as Botox injections, dermal fillers, chemical peels, microdermabrasion, and laser resurfacing can also help reduce the appearance of wrinkles.
