We all have a natural tear trough, even babies.
As we age, and depending on certain ethnicities, these may become more prominent with age, hollowing and appearing darker, causing self consciousness.
In some people, the bags under the eyes may retain water, due to medications, or as a part of their natural physiology, and they may not be suitable candidates for fillers in this area.
In other people, filler in the tear trough can work very well, but because it is typically one of the more difficult and dangerous areas to treat, with a major blood vessel close by, individual assessment is needed to see if volumising the cheeks may work to help with the eye bags first.
To avoid an unnatural result and lumpiness, I tend to use 0.5ml of filler in total in both under eye areas with review in 2 weeks to see if more is needed (it usually is) to avoid overfilling this delicate area. Bruising in this area is very common so please don’t plan this before a big event.
