Why am I losing fat under my eye/how to treat it? (Photo)

Sadly, you are not alone in experiencing a loss of fat in this area. However, there are lots of non-surgical options for fixing the problem. My favorite is a HA filler such as Restylane. Schedule a consultation with a board certified plastic surgeon in your area to be assessed in person and discuss. My best,

 Many young guys loose fat in this area especially if athletic. fillers lasers and skin tightening all can help.  Best, Dr. Emer.

If you look at babies they have fatter faces and as they grow they lose the fat and gain bone and muscle in their face. You are going through yuor growth and this is normal. There is nothing wrong.  

Facial aging, especially around the eyes is more than just
gravity. As we age our facial bones actually lose volume and
surprisingly play an important role in how our face changes.
Our skin also loses elasticity and becomes thinner. If you decided that you
wanted to address those concerns, there are options. Fillers, such
as Restylane Silk will help restore the volume to that area.
Fillers do exactly what their name suggests; they fill in the area under the
skin. Some filler treatments are in the hyaluronic acid family such as the Restylane
Silk mentioned above, whereas some are natural, such as your own fat that can
be injected into that area.
