Reduces blood and lymphatic circulation
(already naturally sluggish) causes fluids to leak into the eyelid tissue (dark circles, under-eye bags, swelling, etc). This stasis leads to puffiness in the eye area and increases the visibility of capillaries through the skin.

Because of the transparent, delicate nature of the eyelid epidermis and dermis, dark circles and under-eye bags are more noticeable and become permanent.

Loss of lipids in the connective tissue
leads to thinning of the skin.

Loss of skin firmness
causes the upper eyelid to sag (“the hood”) and accentuates under-eye bags.

Wearing glasses (few people escape longsightedness after the age of 40!) and the ensuing movement that they cause around the eye (the “tic” of “playing” with your glasses and moving them around the eyes is not always done consciously!) creates microshocks which, repeated over the course of the day for many years, can cause inflammation, pigment spots and vascular spots.

Some habits, such as constantly rubbing the eyes, can crease the eye area.

Daily make-up application, and above all removal, pulls on the eyelashes (risking their falling out or breaking) and dehydrates the eyelids.
