Venus dimples are simply small, symmetrical indentations where the pelvis and spine meet, visible on the lower back when skin and posture reveal the underlying bone structure. They form where ligaments and skin tether closely to the posterior superior iliac spine, and their presence is largely dictated by genetics and body composition, not effort, virtue, or health status. Some people have them, many do not, and neither outcome is better or worse.

What often complicates the picture is confusion with sacral dimples, which sit lower, near the tailbone, and can, in rare cases, be associated with spinal abnormalities that require medical evaluation. Venus dimples, by contrast, are harmless and purely cosmetic, whether called Venus dimples on women or Apollo holes on men. In the end, they are just one more example of how natural anatomical variation becomes loaded with meaning—beauty, desirability, even fear—when, medically, they are simply another way a human back can look.
