The frown lines between your eyebrows respond well to neurotoxin like Botox or Dysport — but the results depend on whether the lines are dynamic or set into the skin. Here's what to realistically expect.
The vertical creases between your eyebrows — often called the "11 lines" or, clinically, glabellar lines — are one of the most common reasons people first consider neurotoxin. The honest answer is nuanced: Botox can dramatically soften these lines, and for many people it makes them all but disappear, but how complete the result is depends on how deeply the line is etched into your skin.
Does Botox actually get rid of frown lines between the eyebrows?
Yes — Botox and other neurotoxins relax the muscles that create the frown, which smooths the lines significantly, though deeply etched lines may soften rather than vanish completely. The frown is created by the corrugator and procerus muscles pulling your brows together. Botox temporarily reduces that muscle activity, so the skin is no longer being repeatedly folded.
When the lines are dynamic — meaning they appear when you frown but smooth out at rest — neurotoxin often clears them almost entirely. When the lines have become static (visible even when your face is relaxed), Botox softens them but may not erase them in one round, because the crease is now set into the skin itself.
How long does it take to see results?
Most people begin to notice softening within 3 to 5 days, with the full effect at around 10 to 14 days. The muscle relaxes gradually, so the change is subtle rather than sudden — which is exactly what you want for a natural result. Results typically last three to four months before the muscle activity slowly returns and a maintenance treatment is considered.
What if my frown lines are still visible at rest?
Static lines that remain when your face is relaxed often need more than neurotoxin alone. Once a crease is etched into the skin, relaxing the muscle stops it from getting deeper but may not fill the existing line. In these cases, a thoughtful plan might combine neurotoxin with a small amount of hyaluronic filler to support the crease, or skin-quality treatments that build collagen over time.
This is where a personalized assessment matters. At KatiFACE, the goal is never to freeze the face but to soften the frown while keeping natural expression — so the strategy depends on your anatomy, not a one-size template.
How much Botox is needed for the frown lines?
The glabellar area typically requires a modest, defined number of units placed across the corrugator and procerus muscles, tailored to muscle strength. Stronger, more active frown muscles generally need a bit more product. Dosing is individualized during a consultation with a registered nurse injector, and over time many people find a consistent personalized dose that works for them.
Will treating my frown lines change my eyebrows?
When placed precisely, treating the frown muscles should not drop your brows — in fact, relaxing the muscles that pull the brow down can give a subtle, refreshed lift. Poor placement is what causes a heavy or surprised look, which is why technique and anatomical knowledge matter far more than the brand of toxin. An experienced injector maps your specific muscle pattern before treating.
Can frown lines be prevented before they get deep?
Starting neurotoxin while lines are still dynamic can help slow the skin from creasing into permanent static lines. There's no "right age" — it depends on how expressive your frown muscles are and how the lines are behaving. Pairing treatment with daily sunscreen and good skincare supports the long game, since sun damage and collagen loss also play a role in how lines set.
What are realistic expectations?
For dynamic frown lines, expect significant smoothing and, often, near-complete clearing at rest. For deeper static lines, expect meaningful softening with the understanding that full erasure may take a combined approach over time. Individual results vary based on anatomy, muscle strength, and skin quality, and neurotoxin is a temporary treatment that requires maintenance. A consultation is the best way to understand what's realistic for your face — you can book a consultation to discuss your options.

Frequently asked questions
Does Botox completely remove frown lines?
It depends on the line. Dynamic lines that appear only when you frown often clear almost completely, while deeper static lines visible at rest usually soften significantly but may need a combined approach to erase fully.
How long do Botox results on frown lines last?
Typically three to four months. The effect fades gradually as muscle activity returns, at which point a maintenance treatment can be considered.
Is Botox or Dysport better for the 11 lines?
Both are effective neurotoxins for glabellar frown lines. The right choice depends on your anatomy and your injector's recommendation; technique and placement matter more than the brand.
Will Botox for frown lines make my forehead look frozen?
Not when dosed and placed appropriately. The aim at KatiFACE is to soften the frown while preserving natural expression, which is why a personalized assessment comes first.
What if my frown lines are still there after Botox?
Deeply etched static lines may remain after the muscle relaxes. These can sometimes be improved by adding a small amount of hyaluronic filler or collagen-supporting skin treatments — discuss this during your consultation.
