Those small indentations just above the buttocks—commonly known as “back dimples” or “Venus dimples”—are more than a unique physical trait. They are an interesting part of human anatomy rooted in your skeletal structure.
Medically referred to as dimples of Venus, these symmetrical indentations sit on the lower back where the skin attaches directly to a bony landmark called the posterior superior iliac spine of the pelvis.
This attachment pulls the skin inward slightly, forming a natural dimple. The result is a visible dip that doesn’t involve muscle or fat but rather the way skin and bone are connected in that region.
