You may have noticed small indentations just above the buttocks on some people’s lower backs — symmetrical little "dents" that catch the light and add a subtle flair to the silhouette.

These are commonly called "Venus dimples" — a poetic nickname inspired by classical beauty. In medical terms, they’re known as sacral dimples or dorsal dimples.

But what exactly are they?
Are they rare?
Do they mean anything about your health or genetics?

Let’s explore the real story behind these natural features — without myths or clickbait.

🧬 What Causes Back Dimples?

Back dimples are shallow skin indentations located just above the buttocks, near the base of the spine.

They form where connective tissue links the posterior superior iliac spine (part of the pelvic bone) to the overlying skin.

Their visibility depends on:

Body fat percentage – Lower body fat often makes them more noticeable
Skin elasticity and structure
Genetics – They tend to run in families, suggesting a hereditary component

✅ They are completely normal — not a defect, flaw, or medical condition.

👩‍🦰 Who Has Them?

More common in women, due to differences in pelvic structure and fat distribution
Also seen in men, though less frequently visible
Appear across all ethnicities and body types

While often associated with beauty and symmetry, having or not having Venus dimples says nothing about your health, strength, or worth.
