Have you ever caught a glimpse of your lower back in the mirror and noticed those two small, symmetrical indentations just above your buttocks? Many people spot these subtle dips and wonder if they’re a sign of something special about their body or health. These features, often called “Venus dimples” or back dimples, spark curiosity because of myths linking them to beauty, fitness, or even enhanced vitality. While they might seem mysterious at first, understanding their true nature can bring reassurance and appreciation for your body’s natural variations. Keep reading to uncover the science behind these dimples—and one surprising connection that research has explored about your pelvic structure.
What Are These “Holes” in Your Lower Back?

These two small indentations are known as dimples of Venus, named after the Roman goddess of love and beauty. They appear as symmetrical dips on either side of your spine, right where your lower back meets your pelvis.

Medically, they’re also referred to as back dimples or lateral lumbar indentations. Unlike a single sacral dimple (which can sometimes warrant a check in newborns), these paired dimples are a normal cosmetic feature in adults.
