The darkening of the under eyes becomes more pronounced with age. This is because as we age our cheekbones begin to resorb in our mid-20s. You could compare this to having less scaffolding to support the tissues holding the fat pads around our eyes and cheeks. Our fat pads are also changing in size and are moving down with age.
The thin skin of the eye area is more transparent as production of elastin and collagen decreases in our skin, especially with the decrease of fat to cover the darker muscle in the tear trough area, enhancing the dark circles and exposing pigment.
By restoring lost volume and stimulating collagen in the tear trough area, the appearance of dark under eye circles can be reduced.
The symptoms of dark under eye circles can be an aging and tired effect and dampened confidence.
Dark under eye circles may be prevented by the daily application of SPF50, avoiding unneccessary sun exposure, a daily collagen supplement and not smoking.
