The under eye seems to be everyone’s least favorite part of the aging face. In order to improve undereye puffiness and darkness, we must first look at what creates this unwanted look.
First the puffiness. Our dermis ranges in thickness from 0.3 - 4mm, a tremendous variation that accounts for the resiliency of our skin in certain areas and relative fragility in others. The backs of the hands and infraorbital (undereye) skin are both areas where the skin is exceptionally thin. It is no coincidence that these are the first areas we can appreciate early signs of aging and chronic ultraviolet exposure. These areas are constantly exposed to environmental radiation that leads to the breakdown of dermal components, such as elastin and collagen fibrils. With weakened elastin, the dermis begins to sag, unable to fight the force of gravity tugging at the upper face. A comparable metaphor is to imagine a sail without a mast that billows, flaps, and sags in the wind.
Next the dark circles. This one is actually very easy to explain. As the infraorbital skin begins to weaken from the loss of elastin and collagen, it thins even further. The dermis under the eyelid, once only 0.3mm in thickness now drops further to 0.1-0.2mm! The result is near-transparency of the skin, like looking through a sheet of wax paper. So what’s behind the dermis that gives that darkened appearance? Blood! Its dark and not bright red because it’s venous blood and when viewed through paper thin skin, takes on a nearly blue appearance.
What to do?
