What Are Glabellar Lines? The Frown Lines Between Your Brows
What are glabellar lines?
Glabellar lines are the vertical creases that form between your eyebrows, often called 11 lines or frown lines. They are created by the corrugator and procerus muscles contracting when you frown or squint. Over time the repeated movement can leave a line that stays visible even at rest.
If you have noticed one or two vertical lines forming between your brows, you are looking at glabellar lines. Here is what they are, why they happen, and what can soften them.
Where are glabellar lines located?
Glabellar lines sit in the glabella, the flat area of skin between your eyebrows and just above the nose. When they appear as two vertical creases they are nicknamed 11 lines. They are different from forehead lines, which run horizontally across the frontalis muscle higher up. Glabellar lines are vertical and central, and they are usually the first thing people notice when someone looks worried or focused.
What causes glabellar lines?
They are mainly caused by muscle movement. Every time you frown, squint against the sun, or concentrate at a screen, the corrugator and procerus muscles pull your brows inward and fold the skin. Repeated over years, that fold becomes a lasting line. Several things speed this up:
- Sun exposure: UV damage weakens collagen and elastin.
- Genetics: some people are simply more expressive or crease earlier.
- Aging: natural collagen loss makes skin less able to bounce back.
- Squinting: uncorrected vision or bright light adds movement.
How are glabellar lines treated?
The most common treatment is a neuromodulator such as Botox, Dysport, Xeomin, or Jeuveau, which relaxes the frown muscles so the skin stops creasing as hard. Softening usually begins in 3 to 5 days, reaches full effect around two weeks, and lasts about 3 to 4 months. Deeper lines that remain at rest may only soften partially and can sometimes benefit from a little dermal filler or resurfacing. Rita builds every plan around natural, balanced results rather than a frozen look. Because the glabella sits near the muscles that shape your brows, careful placement matters, so an experienced injector is worth seeking out. Softening this area often makes the whole upper face look more relaxed and approachable.
Can you prevent glabellar lines?
You cannot stop your face from moving, but you can slow how quickly these lines set in. Daily SPF protects the collagen that keeps skin resilient, and sunglasses cut down on squinting. Some people start neuromodulator treatment earlier to reduce the repeated folding before a deep static line forms. A good skincare routine with a retinoid and steady hydration supports skin quality over time, though results always vary from person to person. If you are noticing early creasing, a consultation can help you decide whether to start treatment now or focus first on prevention.

Frequently Asked Questions
Are glabellar lines and 11 lines the same thing?
Yes. 11 lines is a nickname for glabellar lines, referring to the two vertical creases that can appear between the brows.
Is Botox the only option for glabellar lines?
No. Neuromodulators are the first choice, but deep static lines can also be supported with dermal filler, resurfacing, and good skincare.
Can Botox for glabellar lines look natural?
Yes. The aim is to relax the frown muscles while keeping natural movement, so you look rested rather than frozen. Results vary by person.
Should I treat glabellar lines during pregnancy?
Neuromodulators are not recommended during pregnancy or breastfeeding. It is best to wait and consult your own provider.
