Eye bags, or steatoblepharon, are fat pads under the eye socket that bulge forwards. Although numerous factors, including lack of sleep and allergies, can lead to fluid accumulation in these tissues, they are typically a permanent part of the facial structure.
Their appearance worsens with age as the ligaments holding the pads in place soften.
When applied, XAF5 is absorbed through the skin and into fat tissue. It binds to receptors on the surface of fat cells, causing them to expel their oil contents, reducing their size. It also prevents new fat cells from forming.
