Frown Lines
The '11s' between the brows — softened without freezing expression.
Frown lines — the vertical creases between the eyebrows also known as glabellar or 'number 11' lines — are caused by repeated contraction of the corrugator supercilii and procerus muscles whenever you concentrate, frown or squint. Over time, as collagen and elastin diminish, the skin retains the imprint of those movements. At Feonix Aesthetics in Coventry, we assess your frown lines face to face and talk you through the options that suit your face.
What it is
Frown lines, also known as glabellar lines or the "number 11" lines, are the vertical creases that appear between the eyebrows. They are formed by the repeated contraction of the corrugator supercilii and procerus muscles, which draw the brows together when you concentrate, frown, squint, or express displeasure. Over time, these lines can become deeply etched into the skin and remain visible even when the face is relaxed. Frown lines are one of the most commonly treated concerns in aesthetics because of the disproportionate impact they have on facial expression, often giving the appearance of anger, irritation, or deep concern regardless of actual mood.
More about Frown Lines
Why it happens
The primary cause of frown lines is repetitive muscle contraction. Every time you furrow your brow, the underlying muscles compress the skin between the eyebrows, creating vertical folds. In youth, the skin bounces back smoothly when the muscles relax, but as collagen and elastin diminish with age, the skin retains the imprint of these movements. People who are naturally expressive or who frequently squint, concentrate, or frown tend to develop these lines earlier and more deeply. Sun damage accelerates the breakdown of collagen, and environmental factors such as pollution and smoking further weaken the structural integrity of the skin. Screen use is an increasingly recognised contributor, as the concentration and squinting involved in staring at devices for extended periods can significantly increase the muscle activity in this area.
Skincare can support the skin, but it cannot change how the muscles move; a consultation is the place to talk through the options. That is why frown lines are worth assessing in person: at Feonix Aesthetics we look at how your brow muscles move and how deeply the lines have set before recommending anything. Contact our Coventry clinic to arrange your consultation.
Living with frown lines
Frown lines have a uniquely powerful impact on how others perceive you. Research has shown that the glabellar region is one of the areas people focus on most when reading facial expressions. Deep frown lines can make you appear perpetually angry, stressed, or disapproving, even when you are feeling relaxed and content. This can affect personal relationships, professional interactions, and your own self-image when you see yourself in the mirror. Many clients who seek frown line treatment in Coventry and Warwickshire at Feonix Aesthetics tell us that softening these lines has had a positive impact not only on their appearance but also on how people respond to them in daily interactions.
How we treat frown lines at Feonix
Every frown line plan at Feonix Aesthetics starts with a consultation at our Coventry clinic, where we assess the strength and pattern of the corrugator and procerus muscles between your brows, how deeply the lines have set, and your medical history. If a prescription-only treatment may be appropriate, this will be discussed and assessed by an appropriately qualified prescriber before anything is prescribed. You leave with an honest explanation of your options, including doing nothing.
For deeply established frown lines that remain visible at rest, we assess the area at your consultation and explain the options that are suitable for you.
How long any change lasts depends on the approach and on you. We will explain what to expect from each option at your consultation.
Common questions about frown lines
What causes frown lines?
Frown lines are caused by repetitive muscle contraction combined with age-related collagen loss. Every time you concentrate, frown, squint or express displeasure, the corrugator and procerus muscles pull the skin between the brows into a vertical fold. In young skin, collagen and elastin spring back smoothly. As those proteins deplete with age, sun exposure and lifestyle factors, the skin retains the imprint — static lines remain visible even when the face is relaxed. Naturally expressive people and those who work long hours at screens tend to develop them earlier.
Can I prevent or soften frown lines at home?
Daily broad-spectrum SPF 50 is one of the most important preventive steps — UV damage speeds up collagen loss. Consistent skincare with retinoids, peptides and antioxidants supports collagen health and can mildly soften early lines. Skincare can support the skin, but it cannot change how the muscles move; a consultation is the place to talk through the options. For established deep frown lines, topical skincare is supportive rather than corrective. Prevention in your 20s and 30s has a disproportionately large impact on the decades that follow.
How are frown lines treated?
It depends on how your muscles move and how deeply the lines have set, so it starts with a consultation at our Coventry clinic. Where clinically appropriate, options can include prescription treatments. If a prescription-only treatment may be appropriate, this will be discussed and assessed by an appropriately qualified prescriber before anything is prescribed. You'll get honest advice about what is likely to help, including whether doing nothing is the right call.
How long until I see results?
That depends on the option chosen. We will explain the realistic timeline for your plan at the consultation.
How do I start at Feonix?

How we decide what’s right
Every plan starts with a consultation. We assess your suitability, discuss your goals and review your medical history before recommending anything — and we will tell you if a treatment isn’t right for you. If a prescription-only treatment may be appropriate, this will be discussed and assessed by an appropriately qualified prescriber before anything is prescribed.
