Venus dimples, also known as back dimples, are small indentations located just above the buttocks.
These natural dips form where the skin is attached to a specific point on the pelvic bone called the posterior superior iliac spine.
They aren’t caused by muscle or fat, but by how the skin connects to the bone in that area. This attachment pulls the skin inward slightly, creating a visible dimple on each side of the lower back.
Not everyone has Venus dimples—they depend on your bone structure and body fat distribution. They tend to be more noticeable in individuals with lower body fat, but they can’t be developed through exercise.
While often viewed as attractive and symmetrical in many cultures, Venus dimples have no medical purpose. If you have them, enjoy the unique feature. If not, it’s just another normal variation of the human body.
