What Causes Frown Lines Between the Brows?

Frown Line Treatment

Frown lines between the brows are a common concern, especially as facial movement, skin quality and ageing changes begin to show more clearly over time.

For some people, these lines appear only when they frown, concentrate or squint. For others, they may become visible even when the face is relaxed.

While frown lines are a natural part of expression, understanding why they form can help you make more informed decisions about how to support the area.

What Are Frown Lines?

Frown lines are the vertical lines that can appear between the eyebrows. They are sometimes referred to as lines between the brows or expression lines.

They usually develop in the area between the eyebrows, where the facial muscles are active during expressions such as frowning, concentrating, squinting or looking concerned.

These lines can vary from very fine creases to deeper lines that remain visible at rest.

Facial Movement Plays a Big Role

The area between the brows is highly expressive. Every time we frown, focus, squint or pull the brows together, the muscles in this area contract.

Over time, repeated movement can create lines in the skin. At first, these lines may only appear during expression. As the skin changes with age, they may gradually become more noticeable even when the face is still.

This does not mean you have been doing anything wrong. It is simply the result of natural facial movement over time.

Why Lines Can Become More Visible With Age

As we age, the skin naturally produces less collagen and elastin. These are the structures that help the skin feel firm, smooth and resilient.

When collagen and elasticity begin to reduce, the skin may not bounce back as easily after movement. This can make expression lines, including frown lines, more visible.

The skin may also become thinner or less supported over time, which can make creases appear more defined.

The Forehead and Brow Area Work Together

Frown lines are often discussed on their own, but the brow area is closely connected to the surrounding upper face. Movement through the forehead, brow and eyes can all influence how lines appear between the brows.

For some people, concerns in this area may sit alongside forehead lines, brow heaviness or changes in expression through the upper face. In these cases, Forehead Area concerns may be assessed as part of a broader facial consultation.

Sun Exposure Can Contribute

Sun exposure is one of the biggest contributors to visible skin ageing.

UV exposure can affect collagen, elastin, pigmentation and overall skin quality. Around the brows and upper face, this can contribute to fine lines, roughness and changes in texture.

Squinting in bright light may also increase movement around the eyes and brow area, which can make expression lines more noticeable over time.

Skin Quality Matters Too

Frown lines are not only about muscle movement. Skin quality also plays an important role.

When the skin is dry, dehydrated, dull or lacking support, lines can appear more visible. Well-supported skin often reflects light more smoothly, while depleted skin may show texture and creasing more easily.

For some people, supporting hydration, collagen and overall skin quality may form part of a broader treatment plan.

The Eye Area Can Influence How the Brow Looks

The brow and eye area are closely connected. Changes around the eyes, including skin texture, fine lines, heaviness or tiredness, can affect the way the upper face appears overall.

If frown lines sit alongside concerns such as under eye creasing, brow heaviness or changes around the outer eyes, your clinician may also assess the Eye Area as part of your treatment planning.

Stress, Focus and Everyday Habits

Many people naturally hold tension in the brow area without realising it.

This can happen when concentrating at a computer, driving, reading, working under pressure or feeling stressed. Over time, repeated brow tension may contribute to lines between the brows becoming more noticeable.

Small lifestyle adjustments, such as being mindful of facial tension, wearing sunglasses outdoors and supporting skin health, may help reduce unnecessary strain in this area.

Are Frown Lines Preventable?

Some changes in the skin are part of natural ageing, so it is not always possible to prevent frown lines completely.

However, there are ways to support the skin and reduce factors that may make lines more noticeable.

  • Wearing daily sun protection
  • Using sunglasses outdoors to reduce squinting
  • Keeping the skin hydrated
  • Supporting skin barrier health
  • Avoiding harsh skincare that may irritate the area
  • Being mindful of repeated brow tension
  • Seeking personalised advice if the lines are a concern

Can Treatments Help Support This Area?

Depending on your skin, facial movement and suitability, treatment options may be discussed to support the appearance of frown lines and the surrounding brow area.

For some people, the focus may be on softening the appearance of expression lines. For others, treatment planning may involve supporting skin quality, hydration or collagen over time.

The most suitable approach depends on whether the lines are mainly caused by movement, skin quality, ageing changes or a combination of factors.

Why Consultation Matters

The area between the brows should be assessed carefully before any treatment is recommended.

Your clinician will look at how your face moves, how the lines appear at rest and during expression, your skin quality, your treatment history and your overall goals.

At That Face Place, treatment planning is personalised and considered. The aim is to support a natural-looking result that feels balanced with your face, rather than changing your expression completely.

A Natural Approach to Frown Lines

For many people, the goal is not to remove every line or stop expression entirely. It is to soften the appearance of heaviness or tension while still looking like themselves.

A natural approach considers the face as a whole, including the brow, eyes, forehead, skin quality and facial movement.

This helps ensure treatment planning feels refined, balanced and appropriate for your individual features.
