What is a chin crease?
A chin crease (also called a mental crease) is the horizontal line that sits between the lower lip and the top of the chin. It can look like a fold, dent, or shadow and may be visible at rest or during facial movement. Chin creases vary in depth from person to person and are influenced by facial structure, muscle activity, and age.
A chin crease is normal. Some people explore ways to understand why it appears more prominently on their face and speak with a qualified practitioner about supportive care that may help improve balance in the lower face.
What causes a chin crease?
Cause #1 – Muscle activity
The mentalis muscle lifts the lower lip. Strong or frequent activation can create a horizontal line where the skin folds over the muscle.
Cause #2 – Facial structure
Natural differences in chin shape, projection, and lower lip position can make this fold more visible. Some people are born with a more defined mental crease.
Cause #3 – Skin laxity
Collagen and elastin decrease with age. As the skin loses firmness, areas with active muscles are more likely to show creasing.
Cause #4 – Volume changes
Reduced fat or bone support in the lower face may allow the skin to rest more closely against the muscle, making the crease appear deeper.
Why do I have a chin crease and others don’t?
Factor #1 – Genetics
Inherited bone structure and muscle tone influence how early a chin crease becomes visible.
Factor #2 – Expression patterns
People who tense the chin, pout, or purse their lips may develop a more noticeable crease over time.
Factor #3 – Age related shifts
A crease that was once faint can become more defined as volume and elasticity change.
Factor #4 – Chin shape or recession
A chin that sits further back can highlight the fold beneath the lip, even in younger people.
The impact of a chin crease
Although harmless, a visible chin crease can influence how the lower face appears in photos or soft lighting.
Common concerns include
• the look of a shorter lower face
• visible shadowing beneath the lip
• makeup settling in the crease
• surface irregularities or dimpling during movement
Frequently Asked Questions
Q: What can help me understand my chin crease?
A consultation with a qualified practitioner can assess muscle activity, chin structure, and skin quality. This helps identify what may be contributing to the crease.
Q: Can skincare remove a chin crease?
Skincare cannot change bone structure or muscle activity, but healthy skin habits may support smoother texture. Your practitioner can explain what may be suitable for your concerns.
Q: Are changes permanent?
Non surgical approaches are temporary and require maintenance. Surgical options may offer longer lasting structural changes. Suitability depends on individual anatomy and goals.
Q: Will any supportive care affect my natural expression?
Professional guidance focuses on maintaining natural movement. Your practitioner will explain what is realistic for you.
Q: Are these concerns covered by Medicare?
Cosmetic concerns are not covered by Medicare in Australia unless related to trauma or a medical need.
