Do you have dark circles under your eyes? In the world of asthetics these are called tear troughs. There are several reasons that you may have dark circles under your eyes. The first is a result of a combination of volume loss and skin laxity which both occur as part of the natural aging process.
The volume loss occurs immediately under the lower eye creating the trough while the skin laxity allows a fat pad under your eye, but just above the location of your tear trough, to bulge. The combination of the volume loss and bulging fat pad create the tear trough phenomena. You may also be experiencing two more causes for those dark circles. One of these is that the skin under your eye may be very thin and semi-transparent allowing your purple blood vessels to become visible. Finally, people with darker skin tones may have areas of hyperpigmentation under their eyes.
Dermal fillers are gel-like substances that can be injected into the tear trough to revolumize or fill the area and in doing so, often correct those dark circles under your eyes. Dermal fillers may also reduce the contributing effect of thin skin on those dark circles. If you have hyper-pigmentation under the eyes, this can sometimes be moderated with an under eye serum such as the Environ Vita-Peptide Eye Gel.
