Have you ever looked at a photo of yourself and noticed under-eye bags that seemed more pronounced than in the mirror? You're not alone. Many people are surprised by how different their face looks in pictures, especially when it comes to puffiness or shadows beneath the eyes. But why does this happen—and what can you do about it?

First, it’s important to understand what causes under-eye bags. In most cases, they’re a combination of fatigue, fluid retention, aging, and genetics. As we age, the tissues around the eyes weaken, and fat that normally supports the eyes can move into the lower eyelids, creating puffiness. Lack of sleep, high salt intake, and allergies can also make this area appear swollen or darker.

Photos tend to exaggerate these imperfections for several reasons. Lighting and camera angles can cast unflattering shadows, making bags appear more prominent. Harsh lighting from above, like overhead indoor lighting or the midday sun, can create deep shadows under the eyes. On top of that, smartphone cameras and high-resolution photography pick up every detail, highlighting texture and contrast in the skin—even the things we don’t normally notice in the mirror.
