The tear trough is a natural indentation that runs from the inner corner of the eye along the lower eyelid. With age, thinning skin, volume loss, and changes in midface support can deepen this groove, allowing shadows to form.
Because the skin in this area is especially thin, even subtle changes can make hollows more noticeable. Genetics, sleep patterns, allergies, and pigmentation can further influence how prominent tear troughs appear, often creating a tired or aged look despite overall wellness.
