**Venus dimples**, also called “back dimples,” are the small indentations found just above the buttocks. These natural features form where the skin attaches to a bony point on the pelvis known as the *posterior superior iliac spine*. As the article explains, “this attachment pulls the skin inward slightly, forming a natural dimple.”

Unlike muscle features, Venus dimples aren’t created by exercise. “They don’t involve muscle or fat but rather the way skin and bone are connected,” making them a result of skeletal structure, not fitness.

Some people are born with them, while others aren’t—usually due to differences in bone shape or fat distribution. They tend to be more visible in people with lower body fat.

Culturally, these dimples are often associated with beauty and symmetry, especially in fitness and fashion. However, they serve no medical purpose. “Despite the aesthetic attention, Venus dimples have no known medical function.”

So whether you have them or not, it’s simply a normal variation of human anatomy—“just another natural quirk” of the body.
