Why do eye creams not eliminate existing wrinkles around the eyes?

Eye creams can temporarily make wrinkles less prominent by providing surface moisture, but they have limitations in reversing structural wrinkles that have already formed due to damage to collagen and elastic fibers. The skin around the eyes is considered difficult to improve with home care alone, as it is thinner and has very few sebaceous glands, so a treatment approach that directly affects the dermal layer may be more effective.
