Those small indentations just above the buttocks, often called “back dimples” or “Venus dimples,” are more than just a cosmetic feature—they’re rooted in your anatomy.

Medically known as “dimples of Venus,” these symmetrical indentations mark the spots where the skin is directly tethered to the posterior superior iliac spine of the pelvis.

This unique connection between skin and bone creates a natural concave shape when the surrounding soft tissue is minimal or evenly distributed.

Unlike muscles that can be built through exercise, Venus dimples are largely genetic. If you have them, it’s because your skeletal and tissue structure allows for their formation.

These dimples are often associated with physical fitness, but in reality, they have little to do with body fat percentage or muscle tone.

Historically, they’ve been admired as a symbol of beauty and symmetry, often featured in classical art and sculpture.

Though they don’t serve a major medical function, some physical therapists and trainers use them as a reference point for proper spinal alignment or hip positioning.

So, if you have Venus dimples, know that they’re a natural part of your skeletal makeup—a small anatomical quirk that many find fascinating and beautiful.
