Detailed answer

As we age, the skin's elasticity decreases, and the under-eye area becomes thinner due to the depletion of collagen and fat. This thinning skin makes blood vessels more visible, leading to the appearance of dark circles. Additionally, the loss of fat and collagen also causes a hollowing effect under the eyes, creating a shadowed appearance and the formation of under-eye bags. The ageing process also affects the lymphatic system, which can lead to fluid retention and swelling in the under-eye area, further contributing to the development of bags. Environmental factors, lifestyle choices, and genetics can further accelerate the ageing process and exacerbate the appearance of dark circles and under-eye bags. To minimize their appearance, it is essential to maintain a healthy lifestyle, protect the skin from sun damage, and consider using topical treatments that promote collagen production and improve skin elasticity.
