Frown lines (glabellar lines): causes and the best treatments
The frown line, known medically as the glabellar line, is the vertical crease between the eyebrows and often gives the face a stern or tired expression.
The vertical crease between the eyebrows is one of the best-known and most commonly treated facial wrinkles. Known as frown line or, in technical terms, as glabellar wrinkle, it can give the face an unintentionally stern, tired or worried expression – even when you are relaxed.
This Gloss article explains in detail how frown lines develop and what modern treatment methods are available to smooth them out effectively and give way to a more relaxed expression.

What is a frown line? A definition
A frown line, also known as a glabellar line, is one or more vertical expression lines that form in the glabellar region – the area between the eyebrows, above the bridge of the nose.
It initially forms as a dynamic wrinkle caused by muscle activity, but over time it can also become permanently visible as a static wrinkle.
How do frown lines form? The role of facial expressions
The main cause of the frown line is the repeated contraction of two specific muscles:
- Musculus corrugator supercilii (furrows his brow and lowers his eyebrows)
- Musculus procerus (pulls the skin between the eyebrows downwards)
We use these muscles unconsciously thousands of times a day – when concentrating, when feeling sceptical, when squinting in the sun, or simply when we’re annoyed.
From dynamic to static folds
When we are young, whilst the skin is still elastic, it returns to its normal state completely after every muscle contraction. Over time, and due to the natural breakdown of collagen and elastin, the skin loses its elasticity and firmness, resulting in a permanent indentation at that point. Initially visible only when the muscles are tensed, dynamic fold becomes visible even when relaxed static crease – a permanent indentation.
Treatment methods: What really helps with the frown line?
Creams and serums are generally ineffective against deep, pronounced frown lines. The most effective and tried-and-tested methods are minimally invasive treatments carried out by a qualified specialist.
Option 1: Botulinum toxin (Botox) – The muscle relaxant
Botulinum toxin (known under the brand name Botox®) is one of the most common and effective minimally invasive treatments for frown lines worldwide.
Option 2: Hyaluronic acid fillers – The wrinkle filler
If the frown line is already very deep and remains visible as a distinct „scar“ on the skin even when the face is relaxed, hyaluronic acid may be used.
The key question: should you smooth out frown lines or fill them in?
Imagine a sheet of paper.
- Botox prevents the paper from creasing in the same place time and time again (it tackles the root cause).
- Hyaluron fills in the existing deep crease (it repairs the damage).
An experienced doctor will often combine both methods to achieve the most natural and satisfactory result possible.
Botox vs. hyaluronic acid: Which is right for me?
| Criterion | Botulinum toxin (Botox) | Hyaluronic acid fillers |
|---|---|---|
| Mechanism of action | Relaxes the muscle, smooths the skin | Fills in the wrinkle, lifts the skin’s surface |
| Ideal for… | Dynamic wrinkles, prevention | Deep, static wrinkles (often referred to as ‘combined’) |
| Onset of action | After about 3–7 days | Visible straight away |
| Shelf life | Approx. 3–6 months | Approx. 6–12 months, depending on the product used, skin type and metabolism |
| Treatment objective | Tackling the root causes | Symptom management |
The importance of expertise and risk mitigation
Although the treatment of frown lines is a routine procedure, it must be carried out by an expert. Only an experienced and qualified specialist, such as a plastic and aesthetic surgeon, dermatology or other relevant specialisms, is familiar with the precise anatomy of the facial muscles and can correctly measure out and position the material to achieve a natural result and avoid risks such as drooping of the eyelid.
Even with the utmost care, complications may arise in rare cases, requiring follow-up treatment. A Consequential Costs Insurance provides you with financial security should a medically necessary correction be required following your cosmetic treatment.
Frequently Asked Questions (FAQ) about frown lines
The cost varies depending on the doctor, the region and the materials used. A Botox treatment usually costs between 150 and 400 euros, depending on the region and the doctor. A combined treatment with hyaluronic acid is more expensive.
The injections are administered using extremely fine needles and take just a few minutes. Most patients feel a slight prick, but no severe pain. An anaesthetic cream can be applied if desired.
The effects of Botox wear off gradually. On average, the results for frown lines last for around 3 to 6 months. With regular treatment, the duration of the effects may be slightly extended, as the muscle becomes less active and, in some cases, slightly weaker.
There is currently no alternative to injection therapy that is equally effective against already pronounced frown lines. Methods such as microneedling or special patches can improve the appearance of the skin slightly, but do not address the underlying cause, which is muscle activity.
