Results typically last 3 to 6 months, with most clients returning every 3 to 4 months initially. Around the mouth, treatments such as a lip flip tend to wear off faster because that muscle is constantly in use.
So, when you ask, “How long do anti-wrinkle injections last?”, are you asking when the visible effect disappears, when movement first starts returning, or when you should book again? Those are different points in the treatment timeline. I’m Natasha, sole practitioner at House of Glam HQ in Southsea, Portsmouth, and after more than 7 years of clinical experience, I explain the result as a gradual process rather than a fixed expiry date.
Anti-wrinkle injections, commonly known as Botox, the brand name for botulinum toxin, temporarily reduce targeted muscle activity. They improve the appearance of expression lines, but they don’t stop your face moving forever and they don’t promise a fixed lifespan. UK guidance describes effects as temporary, with many patients experiencing benefit for around 3 to 4 months, while some people may reach closer to 6 months depending on the area, dose and individual response (NHS patient information).
Understanding Anti Wrinkle Injection Duration
A client may look in the mirror a few days after treatment and see a subtle change. Another may feel that the result is still developing at the end of the first week. Neither experience automatically means the treatment has worked too little or too much. At House of Glam HQ, anti-wrinkle injections in Portsmouth begin showing at 3 to 5 days, settle fully at 14 days, and typically last 3 to 6 months.
The first question I ask is what the client wants the treatment to do. Some people want softer frown lines while keeping plenty of expression. Others want a stronger reduction in movement. The dose prescribed and the muscles treated need to match that aim, so two people having the same area treated can still notice different timing.
The result has a beginning, middle and end
The visible effect develops gradually. You won’t see the final result immediately after the injections, and the treatment doesn’t suddenly switch off on a particular day. Movement usually starts to return progressively as the temporary effect reduces.
UK patient leaflets describe a wider range than the familiar three-to-four-month headline. Effects may start within 4 to 14 days, reach their strongest point at around 2 weeks, and then wear off gradually over the following months (North Tees and Hartlepool NHS Foundation Trust information).
That gradual return is normal. It isn’t a treatment failure, and it doesn’t mean the product has stopped working overnight. If your aim is to maintain a natural appearance, returning movement can be the point at which you review your options, rather than a reason to chase an early top-up.
Skin quality also affects how lines look once movement returns. Anti-wrinkle injections and good topical care do different jobs, so a routine focused on topical routines for elastic skin can sit alongside, rather than replace, a clinical treatment plan. If your concern is mainly expression lines, you can also read my guide to anti-wrinkle injections in Portsmouth before deciding whether injections are suitable.
The Biological Timeline from Injection to Wear Off
The treatment timeline is easier to understand when you separate onset, settling, and wear-off. The injection day is the start of the process, not the moment the final result appears.
What happens after treatment
- Injection day: The product is placed into selected muscles after assessment and prescribing. You may notice small injection marks or mild local swelling, but this isn’t the finished cosmetic result.
- Days 3 to 5: Results begin showing at House of Glam HQ. The treated muscles may start to feel less active, and expression lines can look softer.
- The first week: The effect continues developing. It’s too soon to judge the final balance, particularly if several areas have been treated.
- Day 14: The treatment has settled fully. This is why I include a 14-day review with every anti-wrinkle treatment. If a small adjustment is appropriate, it can be considered once the result is visible.
- The following months: The effect remains temporary. Movement gradually returns rather than stopping and restarting.
- Wear-off: Lines may become more noticeable as muscle activity comes back. That change is expected and varies by person and treatment area.
UK guidance also describes effects beginning gradually within 3 to 10 days, becoming strongest at around 2 weeks, then wearing off slowly over 3 to 4 months in many cases (MHRA safety update on botulinum toxin products). The same safety update records that rare symptoms of iatrogenic botulism can appear 4 to 8 days after treatment and, in some cases, take up to 4 weeks to develop. Seek urgent medical advice if you develop concerning symptoms such as widespread weakness, difficulty swallowing, breathing problems or vision changes.
The gradual timing is also why I don’t encourage clients to book an early top-up because they’re impatient during the first week.
For more detail on onset, see my guide to expectations for anti-wrinkle results. The practical point is simple: assess the final result at 14 days, not immediately after the appointment.
Factors That Influence How Long Results Last
No responsible practitioner can promise that an anti-wrinkle treatment will last an exact number of months. I discuss likely duration at consultation by looking at the muscle, the treatment area, your previous response and the result you want to maintain.
Muscle activity and treatment area
Strong, active muscles can bring movement back sooner. Someone with pronounced frown activity may notice a change earlier than someone whose muscles are less forceful. The forehead, frown area, eye area, mouth and jaw also behave differently because they have different patterns of movement throughout the day.
Perioral muscles are used constantly for speaking, eating and facial expression. That’s why a lip flip usually wears off faster than treatment to a less continually active area. The same principle applies when a client exercises intensively, because overall muscle use and individual metabolism are part of the discussion, not something I can predict with certainty.
Dose and clinical judgement
The prescribed dose affects the strength and character of the result. A balanced dose may be chosen to soften lines while retaining natural movement. Increasing the dose just to chase the longest possible duration isn’t automatically better. It can create a result that doesn’t suit your facial movement or personal preference.
I assess the muscles at rest and during expression, then prescribe according to the area and intended outcome. UK clinical guidance describes longevity as dose- and response-dependent, with repeat intervals commonly around 3 to 4 months, although some patients may reach 6 months or longer depending on the indication and response (University Hospitals Sussex botulinum toxin leaflet).
Metabolism, exercise and treatment history
Metabolism varies between people. Intensive exercise may also be relevant when discussing how quickly movement appears to return. These factors don’t let me calculate an exact lifespan, and they shouldn’t be used to promise that one person will have a longer result than another.
Regular treatment may extend the interval for some people as the targeted muscles become less active over time. That isn’t guaranteed, and reduced responsiveness can occur. The British Dental Journal review found published durations ranging from 2 to 6 months, with most patients losing maximal muscle contraction for 3 to 4 months, reinforcing why a single figure doesn’t fit everyone (British Dental Journal review).
Skin condition is a separate consideration. A treatment such as Profhilo treatment may support skin hydration and quality, but it doesn’t replace muscle-targeted anti-wrinkle injections or make their result permanent.
Duration by Treatment Area
The standard facial areas, forehead, frown lines and crow’s feet, generally sit within the House of Glam HQ range of 3 to 6 months. The exact duration depends on the muscle strength, prescribed dose, treatment pattern and how quickly movement returns for you.
| Treatment Area | Typical Duration |
|---|---|
| Forehead | 3 to 6 months |
| Frown lines | 3 to 6 months |
| Crow’s feet | 3 to 6 months |
| Lip flip | Usually shorter because the perioral muscle is constantly in use |
| Masseter | Individual response varies and is assessed case by case |
| Hyperhidrosis | Around 4 to 6 months for reduced underarm sweating |
Facial expression areas
Forehead treatment is often planned carefully because the frontalis muscle contributes to brow position. Frown lines involve strong muscles between the brows, while crow’s feet are linked to movement around the eyes. These areas may all fall within the same broad duration range, but they won’t necessarily wear off together.
That matters for maintenance. You may notice movement returning in one area while another still looks settled. I’d rather review that pattern than automatically repeat every area at the same time. For specific eye-area considerations, see my guide to crow’s feet treatment.
Lip flip, masseter and sweating
A lip flip treats a small muscle around the mouth. Because that muscle works repeatedly through ordinary daily activity, the result tends to wear off faster. It’s a subtle treatment, and it isn’t the same as lip filler, which adds volume rather than changing muscle activity.
Masseter treatment is assessed separately because the aim may relate to jaw muscle activity and facial shape. At House of Glam HQ, a masseter treatment is £180. Hyperhidrosis treatment is also different from facial anti-wrinkle treatment. It reduces underarm sweating for around 4 to 6 months, and the price is £350.
For facial anti-wrinkle injections, my published House of Glam HQ prices are £170 for 1 area, £210 for 2 areas and £250 for 3 areas. A lip flip is £150. These are treatment prices, not a promise that every client needs the same number of areas.
Aftercare and Maintenance Planning
Good aftercare won’t make the result last beyond your biology. It protects the treatment while it settles, which is the part you can influence. I give clear instructions because simple mistakes, particularly pressure on treated areas or lying flat too soon, can interfere with how the product settles.
For the first 24 hours, avoid:
- Exercise: Skip intensive activity during the initial settling period.
- Heat: Avoid hot environments and anything that leaves your face overheated.
- Alcohol: Leave alcohol out during the first day.
- Pressure: Don’t massage the treated areas or apply unnecessary facial pressure.
- Lying flat: Keep upright for 4 hours after treatment.
Daily SPF is sensible for general skin protection and helps limit the environmental factors that can make lines look more noticeable. It doesn’t extend the biological action of the injections.
The full guidance is covered in my essential 24-hour aftercare rules. No aftercare guarantees longer duration. It protects the result you have.
The review comes before maintenance
Every House of Glam HQ anti-wrinkle treatment includes a 14-day review. This is when I check how the product has settled and consider any small adjustment that may be appropriate. It isn’t an invitation to add treatment before the result has developed fully.
Most clients return every 3 to 4 months initially, but intervals are agreed case by case. I don’t sell a fixed maintenance package or encourage early top-ups because a certain date has arrived. If movement has only just started returning, waiting may be more sensible than treating again immediately.
The required £25 prescriber consultation is paid once per prescription period and is legally required before a first treatment because botulinum toxin is a prescription-only medicine in the UK. You can book a standalone consultation on Fresha, with a £15 deposit deducted from treatment if you go ahead, or book treatment directly and the consultation happens at the start of the appointment with no separate fee. Klarna is available on treatments through three monthly payments.
Common Misconceptions About Results Fading
Anti-wrinkle results don’t usually vanish suddenly. Movement tends to return gradually, which means you may first notice a small amount of expression, followed by a slow increase over time. That’s the expected wearing-off pattern described in UK patient guidance (BAAPS information on botulinum toxin injections).
Returning movement also doesn’t mean the treatment failed. The effect is temporary by design. The aim is usually to soften expression lines while keeping your face looking like your face, not to hold every muscle completely still indefinitely.
Some patients notice wearing-off symptoms a few weeks before their next injection, while published pathways can vary according to indication and response. The sensible approach is to judge your own movement and appearance at review, then agree the next appointment without rushing.
If you’re still seeing a developing result during the first two weeks, wait. If you notice unexpected symptoms or widespread weakness, contact a medical professional urgently rather than booking a cosmetic top-up.

Frequently asked questions
How long do anti-wrinkle injections last?
Results at House of Glam HQ typically last 3 to 6 months, although duration varies by person, dose, muscle strength and treatment area. Most clients return every 3 to 4 months initially.
When do anti-wrinkle injections start working?
Results begin showing at House of Glam HQ within 3 to 5 days. The treatment settles fully at 14 days, which is why the included review takes place then.
Do anti-wrinkle injections wear off suddenly?
No. Movement normally returns gradually as the temporary effect reduces. A gradual return of movement is normal and doesn’t mean the treatment has failed.
Does a lip flip last as long as forehead treatment?
Usually not. A lip flip tends to wear off faster because the perioral muscle is constantly used for speaking, eating and expression.
How long does hyperhidrosis treatment last?
Hyperhidrosis treatment typically reduces underarm sweating for around 4 to 6 months. It’s assessed separately from facial anti-wrinkle injections.
Should I book a top-up before the result has fully settled?
No. Wait until the treatment has settled at 14 days unless you’re advised otherwise. The review is included and is the appropriate point to assess whether a small adjustment is needed.
