The forehead forms the upper third of the face and plays an important role in facial aesthetics.

Its height, slope, curvature, and relationship to the eyebrows influence overall facial proportions and the profile.

The glabella is the area between the eyebrows, just above the bridge of the nose.

Aesthetic treatment of the forehead and glabella aims to create a balanced appearance while preserving natural facial anatomy and expression.

Why Is the Forehead Important in Facial Aesthetics?

The forehead extends from the hairline to the eyebrows. It is assessed together with the temples, eye area, and nasal bridge.

The main features that shape its appearance include:

• Forehead height and width
• Curvature viewed from the front and side
• The slope of the forehead bone
• The prominence of the brow ridges
• The transition between the glabella and nasal bridge
• Brow position and facial muscle movement

A flat, prominent, or rounded forehead does not necessarily indicate an aesthetic concern. Its relationship to the rest of the face is what matters.

How Does Forehead Anatomy Differ Between Women and Men?

On average, female and male faces may have certain anatomical differences.

Women often have a more rounded forehead contour with softer transitions and less prominent brow ridges.

Men may have more prominent brow ridges and a more pronounced glabella. In some men, the forehead profile appears more sloped and angular.

However, these are general observations. There is considerable anatomical variation within both groups.

Aesthetic facial assessment should guide treatment toward results that complement each person’s features, without relying on a standard female or male facial template.

What Is the Glabella, and How Does It Affect Facial Appearance?

The glabella lies between the eyebrows, just above the bridge of the nose.

Its appearance depends on two main factors:

Bone structure: The anatomical relationship between the brow ridges, forehead bone, and nasal bridge.

Muscle movement: The activity of facial muscles that draw the eyebrows together and downward.

These muscles are particularly active during frowning.

Over time, repeated facial movements, reduced skin elasticity, and aging can make frown lines visible even when the face is at rest.

How Do Forehead and Glabellar Wrinkles Form?

Horizontal Forehead Lines

Horizontal forehead lines develop largely through the activity of the frontalis muscle.

This muscle raises the eyebrows.

People who frequently raise their brows may notice these lines earlier.

Frown Lines

Vertical lines between the eyebrows are associated primarily with the corrugator supercilii and other muscles involved in frowning.

These lines may deepen over time.

Horizontal Lines Above the Nasal Bridge

Activity of the procerus muscle can create horizontal lines across the lower glabella, near the top of the nasal bridge.

Their appearance varies with individual muscle anatomy and patterns of facial movement.

How Are Forehead Curvature and Glabellar Prominence Assessed?

A profile assessment considers the slope of the forehead, the prominence of the brow ridges, and the transition to the nasal bridge together.

The outward curvature of the upper forehead and the forward projection of the glabella are distinct anatomical features.

Some people have a gently convex forehead with a more prominent glabella. Others have a smoother transition from the forehead to the nasal bridge.

There is no single ideal forehead angle for everyone.

Facial character reflects the relationships among the forehead, nose, chin, eyebrows, and cheekbones.

How Does Aging Change the Forehead and Brows?

Aging involves reduced skin elasticity, repeated muscle movements, and changes in supporting tissues.

Over time:

• Forehead lines may become more noticeable.
• Brow position and shape may change.
• Excess skin may develop around the eyes.
• The temples may lose volume.
• The contours around the forehead and brows may change.

People who feel heaviness in their eyelids may unconsciously keep their eyebrows raised.

In these cases, forehead lines may reflect an ongoing effort to hold the brows up.

Brow position should therefore be assessed before wrinkle treatment.

What Treatments Are Used for the Forehead and Glabella?

1. Botulinum Toxin Injections

Botulinum toxin is one of the main treatments used to soften expression lines on the forehead and between the eyebrows.

The glabellar frown muscles and the frontalis muscle are assessed according to each patient’s facial movement patterns.

Treatment aims to reduce excessive muscle activity in suitable patients while preserving natural expression.

Because the forehead and glabellar muscles work together, treatment should be planned with their combined function in mind.

Inappropriate muscle targeting or dosing may cause brow drooping, eyelid drooping, or an unwanted change in brow shape.

2. Treatments to Improve Skin Quality

For fine surface lines and changes in skin quality, suitable patients may benefit from topical retinoids, sun protection, and selected skin resurfacing procedures.

Fractional lasers and certain other dermatologic procedures may help improve skin texture.

These treatments do not change bone structure or prominent bony contours.

3. Forehead Volume Restoration

Injectable treatments may be considered for forehead contour irregularities or volume loss in selected patients.

However, the forehead—and particularly the glabella—carries a very high risk for filler injections because of its vascular anatomy.

Complications can include vascular occlusion, skin necrosis, and, very rarely, permanent vision loss.

Forehead or glabellar filler injections should therefore not be considered routine wrinkle treatments. Safer alternatives should be reviewed first.

4. Structural and Surgical Approaches

Botulinum toxin cannot correct prominent forehead bones, differences in hairline position, or contours determined by bone structure.

Surgical assessment may be appropriate for selected patients with these concerns.

How Can a Natural Forehead and Brow Appearance Be Preserved?

A natural-looking result does not require every line to disappear.

Forehead movements are an important part of communication.

Planning that preserves natural brow movement and considers the eye area and overall expression may produce a more balanced result.

For some patients, subtle softening of forehead lines is enough. For others, reducing muscle activity between the eyebrows is a greater priority.

Appropriate treatment should address the anatomical factors behind a wrinkle as well as its location.

Dermatologic Facial Assessment and Treatment Planning

At Dr. Armin Müştak’s private dermatology practice, the forehead and glabella are assessed together with brow position, facial muscle activity, temple contours, and overall facial proportions.

For suitable patients, botulinum toxin and dermatologic procedures that support skin quality may be planned based on individual needs.

The aim is to achieve a balanced, realistic aesthetic improvement while preserving natural facial expression and anatomical features.

A sound approach to forehead aesthetics considers the forehead, glabella, brows, and eye area as a whole when planning treatment.
