Your face shape likely isn’t something you think about often, but understanding it can serve you well. Everything from picking a hairstyle to choosing flattering sunglasses to determine the best makeup techniques hinges on this anatomical detail. 
 
Your face shape is determined by your underlying bone structure, which is based on genetics. However, your face shape can appear to change slightly as you age due to collagen loss in the skin, giving your face a less defined look. 
 
In this article, we’ll share the most common face shapes, how to determine which shape most closely resembles yours, and how to support your facial structure as you age.

The 6 Most Common Face Shapes  

There are six common face shapes, each with its own unique attributes. These include: 
 

Oval

• Cheekbones are the widest part of the face
• Curved jawline and chin
• Tall forehead 
• Face is longer than it is wide 

Square

• Forehead, cheeks, and jawline are roughly the same width 
• Jawline is slightly angled and sharp with a very minimal curve 
• Face is about as wide as it is long 

Round

• Cheekbones are the widest part of the face 
• Sides of the face curve slightly outward
• Chin is rounded 
• Face is almost as wide as it is long 

Rectangle

• Forehead, cheeks, and jawline are roughly the same width 
• Jawline is slightly angled and sharp with a very minimal curve 
• Face is longer than it is wide 

Heart

• Forehead is the widest part of the face 
• Jawline is narrow with a pointed chin 
• Hairline is rounded or has a widow’s peak 
• Face is almost as wide as it is long 

Diamond

• Cheekbones are the widest part of the face 
• Chin is pointed, cheekbones are high, and hairline is narrow 
• Face is longer than it is wide 

How to Determine Your Face Shape

Now that you have a better idea of each face shape, it’s time to determine which shape most closely matches yours. 
The easiest way to determine your face shape is to trace your face in a mirror. To do this, simply look in a mirror and trace the outline of your face on the mirror using lipstick, washable marker, or anything else that’s removable. Step back from the mirror and use the above guidelines to determine your face shape based on the outline. 

How The 6 Different Face Shapes Age？

While aging is a universal process, our unique facial structure plays a significant role in how we age. Understanding your face shape can help you anticipate future changes and target your skincare routine more effectively. Here’s a breakdown of how the six primary face shapes tend to age, supported by insights from clinical research.

Oval Face Shape

Oval faces tend to age evenly. However, their primary challenge is often volume loss in the mid-face, which can lead to the formation of tear troughs (hollows under the eyes) and more prominent nasolabial folds (smile lines). This experience is directly linked to one of the primary mechanisms of facial aging: volume loss. Landmark 3D imaging research from the Aesthetic Surgery Journal demonstrated that aging is not just about sagging skin, but significant "deflation," particularly in the mid-face. This loss of underlying support is what contributes to hollowing under the eyes and the deepening of smile lines.

Square Face Shape

The robust bone structure of a square face provides excellent support for the skin, making it highly resistant to jowling and sagging in the lower face. The science behind this exceptional support lies in the mandible itself. A study on the aging facial skeleton, published via the National Library of Medicine, explains that a strong, well-defined mandible provides a powerful anchor against the downward pull of gravity. The challenge is that as cheek fat descends with age, it can settle in the lower face, sometimes making the jawline appear heavier or more "bottom-heavy."

Round Face Shape

People with round faces often look younger for longer due to the ample fat distribution that keeps the skin looking plump. The downside is the lack of a strong, angular bone structure for support. This is rooted in the interplay between soft tissue and the underlying structures. Research in the Aesthetic Surgery Journal on facial retaining ligaments provides a clear explanation. These ligaments act as anchors for the skin and fat. On a face with less prominent bone structure, these ligaments bear more of the load. As they weaken with age, the ample soft tissue of a round face is more susceptible to generalized sagging, leading to the formation of jowls and a less defined neck.

Rectangle Face Shape

Like a square face, rectangle face shape structure provides good support. However, the primary aging challenge is that the loss of volume in the cheeks can make the face appear more gaunt or hollow over time, which can create a tired appearance. The eye area may also lose volume early, making crow's feet more noticeable.

Heart Face Shape

Heart face shape often sees the most dramatic visual shift. The youthful, high cheekbones rely on well-positioned fat pads. As these pads descend with gravity, volume is lost from the upper face and accumulates in the lower face. This leads to deepened nasolabial folds and the formation of jowls, effectively "inverting" the youthful heart shape.

Diamond Face Shape

The high, strong cheekbones provide excellent mid-face support, making diamond faces very resistant to sagging cheeks and nasolabial folds. Their primary challenge is volume loss in other areas, specifically the temples and the under-eye area, which can create a hollowed or sunken appearance.
