Research from sources like Healthline and anatomical studies shows they’re created by a short ligament that tethers the skin to the posterior superior iliac spine—the bony points on your pelvis. This ligament pulls the skin inward, forming the visible dip over the sacroiliac joints.

Why Do Some People Have Them and Others Don’t?
The presence of Venus dimples is largely genetic. If your parents or close relatives have them, you’re more likely to as well. They’re more noticeable in people with lower body fat percentages because excess fat around the lower back and hips can smooth them out.
Studies indicate they’re fairly common, especially in women, though men can have them too (sometimes called “Apollo dimples”). A toned physique often makes them stand out more—think of how they accentuate the curve of a fit lower back in clothing like backless dresses or swimwear.
Here’s what influences their visibility:
Genetics — The main factor; they’re inherited.
Body composition — Leaner individuals see them more prominently.
Muscle tone — Strong lower back and core muscles can enhance their appearance.
Posture — Good alignment in the pelvis and spine may highlight them.
