Ever Wondered About Those Two Marks on Your Lower Back? The Reason May Surprise You

Have you ever noticed two small dimples on your lower back, just above your buttocks, and wondered why they are there? Perhaps you spotted them in a mirror, noticed them while getting dressed, or saw them on someone else and became curious about their meaning.

These small indentations are commonly known as Venus dimples in women and Apollo dimples in men. Their anatomical name is dimples of the lower back, and they are usually located on either side of the spine, near the point where the pelvis meets the lower back.

For some people, these marks are clearly visible. For others, they are faint or hidden beneath a layer of skin and body fat. Some people have them naturally from childhood, while others may only notice them as their body composition changes.

But what actually causes these two marks? Are they a sign of good health, a result of exercise, or an indication that something unusual is happening beneath the skin?

The explanation is largely anatomical and it is more interesting than many people realize.

1. What Are the Two Dimples on the Lower Back?

The two small indentations are usually found on either side of the lower spine, near the upper part of the buttocks. They often appear roughly symmetrical, although their depth and visibility can differ from one side to the other.

These dimples correspond approximately to the posterior superior iliac spines (PSIS), which are bony landmarks at the back of the pelvis. You can think of these landmarks as two points on the rear of the pelvic bones, one on each side.

The dimples form because of the way the skin and underlying connective tissues attach around these areas. Where the skin is tethered more firmly to deeper structures, a small depression may appear at the surface.

Unlike a wound, scar, or skin lesion, ordinary lower-back dimples are generally not signs of tissue damage. They are a normal variation in human anatomy.

Their visibility depends on several factors, including:

• The shape and position of the pelvic bones.

• The arrangement of connective tissue beneath the skin.

• The thickness of the skin and underlying soft tissue.

• Genetics and individual body structure.

• Lighting, posture, and the angle from which the back is viewed.

This is why two people with similar body shapes may have very different-looking lower backs. One may have prominent dimples, while the other has none that are easily visible.

2. Why Are They Called Venus Dimples and Apollo Dimples?

The names Venus dimples and Apollo dimples come from classical mythology.

Venus was the Roman goddess associated with love and beauty, while Apollo was associated with beauty, music, and other attributes. Over time, the terms became popular in descriptions of the small, symmetrical indentations sometimes seen on the lower back.

The labels are informal rather than medical diagnoses. They are also not exclusive to one sex: people of any sex can have these dimples.

The names may make the feature sound mysterious or unusually significant, but the underlying explanation is straightforward. These indentations generally reflect normal differences in pelvic anatomy and the attachment of soft tissues.

They do not indicate a particular personality, fertility level, sexual ability, or overall state of health.

Although the names have become popular in fashion, fitness, and beauty discussions, the anatomical explanation is more useful than any symbolic interpretation.

3. What Actually Causes These Two Marks?

The main reason these dimples appear is the relationship between the pelvic bones, connective tissue, and skin.

At the back of the pelvis, the posterior superior iliac spines provide recognizable anatomical landmarks. Ligaments and other connective tissues attach around this region, and the skin may be more firmly tethered in certain spots. This can create the characteristic indentations visible on the surface.

However, there is no single explanation that accounts for every person's dimples. Their appearance reflects a combination of anatomy and individual variation.

The role of your pelvic structure

Your pelvis is a ring-shaped structure made up of several bones that support your upper body and connect it to your legs. The shape of this structure differs naturally from person to person.

The bony landmarks at the back of the pelvis can influence where indentations appear and how pronounced they look. Differences in pelvic shape and the surrounding soft tissues help explain why some people have deep dimples while others have barely noticeable ones.

The role of connective tissue

Connective tissue helps anchor the skin to deeper structures. When these attachments create a localized pull on the skin, a small depression can form.
