In addition to tiredness or old age, several factors can contribute to dark circles. In most cases, dark circles are nothing to worry about. However, for cosmetic purposes, most people would rather not have them.
Fatigue
Sleep deprivation commonly causes your skin to appear dull or pale, which exposes dark tissues and blood vessels. Fatigue also often causes the area below your eyes to darken.
Puffy eyelids, which may form shadows that appear as bags under your eyes, are also common.
Age
Aging causes thinning of the facial skin.1 With age, skin loses elasticity, allowing the dark tissues and vessels underneath to show.
Sun Overexposure
Overexposing your eyes to the sun can trigger the overproduction of melanin, the pigment that gives skin its color. Excess melanin production around the eyes will darken the area.
Liver Disease
A rare disorder called porphyria cutanea tarda (PCT), which involves the build-up of proteins called porphyrins in your liver, causes painful blisters and fragile skin that worsens when exposed to sunlight.5 It may cause darkening of the skin.
Your eye doctor can inject platelet-rich plasma or hyaluronic acid-based dermal filler or PLLA fillers such as Restylane or Aqua Secret, Devolux into your under-eye tissue. This fills up lost facial volume and reduces or eliminates dark circles.
