In short. Wear-off, the etched line underneath, and whether stopping makes anything worse. What returns, what does not, and why it can look worse when it is not.
Key points
- When treatment stops, the muscle returns to the activity it had before and the crease returns to the depth it would have reached.
- What changed during treatment was the folding, and what changes after it is nothing more than that.
- The face continues to age at the rate it was always going to age.
People put off stopping a relaxing treatment because of a belief that the muscle comes back stronger, or that the line returns worse than it would have been otherwise. It is worth addressing directly, because it keeps people in treatment past the point where they still want it.
Wear-off is gradual, not a switch
The effect fades over weeks as the nerve endings recover, and the movement returns in the same order it left: faint at first, then more. The line returns as the fold returns, and the process takes long enough that most people notice a gradual change rather than an event.
What is underneath has not gone anywhere
The etched part of the crease was in the skin before the first treatment and it is still there. While the muscle was quiet the groove was not being reinforced, so it often looked softer, and part of what people miss after stopping is that softness rather than the absence of the line. It is a real difference, and it is not the same as the groove having been repaired.
What does not get worse
The muscle does not come back stronger. Nothing about a temporary reduction in movement makes the muscle more powerful when the effect ends, and the line does not return deeper than it was before the first treatment. Stopping does not accelerate anything, and a face that stops is not on a worse course than a face that never started.
The honest position on stopping
When treatment stops, the muscle returns to the activity it had before and the crease returns to the depth it would have reached. What changed during treatment was the folding, and what changes after it is nothing more than that. The face continues to age at the rate it was always going to age.
Why it can feel worse when it is not
You get used to a face without the line. When the movement returns, the crease reappears in a face that has been read as smooth for months, and the contrast makes it look more prominent than it did at the start. Comparing against a photograph taken at rest before the first treatment is the only way to tell a returning line from a memory.
Three things worth knowing before stopping
- Stopping does not damage the muscle or deepen the line; the crease returns to the depth it would have reached anyway.
- A line that looks worse some years later is usually ordinary ageing against a memory, not a consequence of stopping.
- Shortening the interval to hold the effect at its peak is not the same as treating well.
What the treatment reaches while it lasts is covered in botulinum toxin for frown lines. What it never reached is described in resurfacing the etched glabellar line, and the point at which further treatment stops adding anything is set out in the honest ceiling.
Frequently asked questions
Does the muscle come back stronger after treatment stops?
No. Nothing about a temporary reduction in movement makes the muscle more powerful when the effect ends, and the line does not return deeper than it was before the first treatment. What happens is that the muscle returns to the activity it had, and the crease returns to the depth it would have reached anyway.
Why does the line look worse to me after I stop?
Usually because you have been reading your face without it. When the movement returns, the crease reappears in a face that has looked smooth for months, and the contrast makes it more prominent than it was at the outset. The only way to tell a returning line from a memory is to compare against a photograph taken at rest before the first treatment.
Is there any harm in stopping suddenly rather than tapering?
There is nothing to taper. The effect fades on its own schedule as the nerve endings recover, and stopping simply means not repeating the treatment. No rebound effect follows, and no particular timing makes stopping safer or less safe than any other. The decision can be made again at any point.
Risks & Limitations
- Relaxing the corrugator and the procerus also lifts the medial brow, and in a brow that already sits high that lift can become the complaint rather than the result.
- A drooping eyelid, double vision, or difficulty swallowing, speaking or breathing after an injection needs emergency care rather than a wait-and-see approach.
- Resurfacing carries a risk of pigment change and, rarely, of scarring, and its result is judged weeks after the last session rather than on the following morning.
- No rung removes a crease that is established in the skin. A line that is visible at rest usually softens, and any statement that promises more should be treated with suspicion.
When to Seek Care
- Difficulty breathing, chest pain, or difficulty swallowing or speaking after an injection needs emergency care immediately.
- A drooping eyelid, double vision, or an eye that will not close fully after treatment.
- Weakness or numbness on one side of the face, or a brow that has dropped on one side.
- A crease that has appeared or deepened over weeks rather than years, or any change in vision on one side.
