Anti-Wrinkle Injections in Knightsbridge: The Complete Guide

What are anti-wrinkle injections and how do they work?

Anti-wrinkle injections are tiny doses of botulinum toxin type A placed into specific facial muscles. The medicine temporarily blocks the nerve signal that makes the muscle contract, so the skin above it folds less and expression lines soften. Nerve signalling gradually recovers, so the effect wears off over several months.

Every time you frown, raise your eyebrows or squint, small muscles pull the skin into folds. Over years, those repeated folds become the familiar frown lines between the brows, horizontal forehead lines and the fan of crow’s feet at the outer eye. Botulinum toxin works on the junction between nerve and muscle, reducing the release of acetylcholine, the chemical messenger that tells the muscle to contract. A treated muscle still exists and still works a little; it simply cannot pull as hard.

In the UK, botulinum toxin is a prescription-only medicine. NHS guidance on choosing a practitioner explains that it can only be prescribed after a consultation with a healthcare professional such as a doctor or nurse prescriber, and that the prescriber must make sure whoever injects it is trained to do so. That is why a proper consultation is not a formality: it is a legal and clinical requirement.

Those figures, from the International Society of Aesthetic Plastic Surgery (ISAPS) 2024 survey, make botulinum toxin the most common non-surgical aesthetic treatment in the world for both women and men. Popularity is not the same as suitability, though, and the rest of this guide is about deciding whether it is right for your face.

Which areas can anti-wrinkle injections treat?

The most common areas are the frown lines between the brows, horizontal forehead lines and crow’s feet. Experienced prescribers also treat bunny lines, a downturned mouth, neck bands and the masseter muscle for jaw slimming or clenching, and use the same medicine for excessive underarm sweating.

The upper face (frown, forehead and crow’s feet) is where the evidence is strongest and where most people start. Lower-face and neck treatments can be very effective in the right hands, but the muscles there control speech, smiling and swallowing, so precise placement and conservative doses matter even more. At Levirgo we discuss these areas only after assessing how your face moves at rest and in expression. You can see all of the options on our anti-wrinkle injections treatment page.

Beyond wrinkles, the British Association of Dermatologists notes that botulinum toxin injected into the skin can block sweating in hyperhidrosis, with an effect that usually lasts 2 to 6 months and occasionally up to 12 months. Jaw (masseter) treatment for clenching or a square lower face is another well-established use, typically assessed alongside any dental history.

Who is a good candidate, and who should not have treatment?

Good candidates are healthy adults over 18 bothered by lines that appear with movement and who want a softer, natural result rather than a frozen one. Treatment is avoided in pregnancy and breastfeeding, certain neuromuscular conditions, infection at the injection site, and known allergy to the product.

Treatment tends to suit you if

• Your main concern is lines that appear or deepen when you frown, raise your brows or smile.
• You want to look rested and less stern or tired, while keeping recognisable expression.
• You are happy to return every few months if you like the result, or to let it wear off if you do not.
• You have realistic expectations: softer lines, not a different face.

Treatment is usually postponed or avoided if

• You are pregnant, trying to conceive or breastfeeding.
• You have a neuromuscular condition such as myasthenia gravis or Lambert-Eaton syndrome.
• You have an active infection, cold sore or inflamed skin in the area.
• You have had an allergic reaction to a botulinum toxin product before.
• You take certain medicines that interact with neuromuscular transmission, such as aminoglycoside antibiotics. Your prescriber will check your medication list.
• You have an important event within two weeks and have never had treatment before, since results take time to settle.
• You are under 18. Under the Botulinum Toxin and Cosmetic Fillers (Children) Act 2021, cosmetic botulinum toxin injections for under-18s are illegal in England.

A good consultation also explores why you want treatment. NHS advice encourages anyone considering a cosmetic procedure to be clear about their reasons and to take time to decide. If a concern is causing significant distress, or you find yourself wanting more and more treatment, a responsible practitioner will say so and may suggest talking to your GP first.

How well do anti-wrinkle injections work? What the evidence shows

The evidence is strong for frown lines. A meta-analysis of seven randomised trials involving 1,474 people found a standard 20-unit dose far more effective than placebo, with no significant difference in adverse events. In one key trial, 77% of patients had none or mild frown lines at day 30.

The best-studied area is the glabella, the frown lines between the brows. In a double-blind, placebo-controlled trial published in Plastic and Reconstructive Surgery in 2003, 273 patients with moderate or severe frown lines received either placebo or 20 units of botulinum toxin type A spread across five injection points. Their lines were assessed at 7, 30, 60, 90 and 120 days.

Crucially, the treated group stayed significantly better than placebo at every visit up to day 120, which is where the familiar “three to four months” guidance comes from. A 2015 meta-analysis pooled seven randomised, placebo-controlled, double-blind trials (1,474 participants, all using 20 units) and concluded that a single dose was remarkably effective, including for the appearance of lines at rest, with no significant difference in the frequency of adverse events compared with placebo. A 2022 network meta-analysis comparing different licensed type A products found all of them far superior to placebo.

Two honest caveats. First, trial results describe groups, not individuals: muscle strength, skin thickness and sun damage all change how you respond. Second, most trials use standardised injection patterns; real-world treatment is tailored, which can improve natural-looking results but depends heavily on the skill of the person planning your dose.

Dosing explained: units, lighter doses and avoiding a frozen look

Dose is measured in units that are specific to each licensed product, so numbers cannot be compared across brands. A lighter dose keeps more movement but may wear off sooner; a fuller dose smooths more and often lasts longer. A frozen look usually means too much product or poor placement.

You will often see treatment described by the number of units. In the pivotal frown-line trials, 20 units of one product were split across five points. That figure is useful context, but it does not transfer: units of one type A product are not interchangeable with units of another, and the right dose for a strong male frown differs from a light female one. A responsible clinic tells you which licensed product it uses and records the dose in your notes.

Why faces end up looking “done”

• Over-treating the forehead without balancing the frown muscles can drop the brows and make the upper face feel heavy.
• Ignoring asymmetry: most faces move unevenly, so identical doses on both sides can look unnatural.
• Treating to a template rather than watching how your individual muscles pull.
• Adding too much at once instead of starting conservatively and reviewing at two weeks.

What happens during treatment? A step-by-step guide

A first appointment includes a medical consultation, face-to-face assessment and consent, then about ten minutes of injections with a very fine needle. Most people return to normal activities the same day. A review at around two weeks checks the result and allows a small adjustment if needed.

1. Consultation and medical history

   Your prescriber asks about your health, medicines, allergies, previous treatments and what bothers you. The General Medical Council requires doctors to physically examine patients before prescribing injectable cosmetic medicines, so this cannot be done by phone or online.

2. Assessment at rest and in motion

   You will be asked to frown, raise your brows and smile so the practitioner can map the strength and direction of each muscle, and note any asymmetry or brow heaviness.

3. Plan, price and consent

   You agree the areas, the product and an approximate dose, see the price in writing, and discuss side effects. You should never feel rushed to proceed on the day.

4. Treatment

   The skin is cleaned and small amounts are injected at marked points. Most people describe quick pinpricks; no anaesthetic is usually needed. The injections themselves take around ten minutes.

5. Aftercare advice

   Avoid rubbing or massaging the area, strenuous exercise, saunas and facials for the rest of the day. Tiny bumps settle within minutes to hours; a small bruise may take a few days.

6. Two-week review

   Results have usually settled by two weeks. A follow-up review at this stage lets your practitioner check whether a muscle has fully responded and, if needed, adjust conservatively.

When will I see results, and how long do anti-wrinkle injections last?

Softening typically begins within a few days and builds to a peak at around two to four weeks. In clinical trials of frown lines, results remained significantly better than placebo at 120 days, so most people plan treatment roughly every three to four months.

There is no need to repeat treatment on a fixed schedule. Some people prefer to wait until movement has fully returned; others book when lines start to reappear. Letting treatment wear off completely is safe: your face returns to how it would have looked without treatment, not worse. What changes over time is the skin itself, which is why many patients pair toxin with daily sun protection and, where needed, skin boosters or polynucleotides to improve skin quality.

Are anti-wrinkle injections safe? Side effects and risks

In licensed products given by trained prescribers, side effects are usually mild and temporary: redness, small bruises or headache. A drooping eyelid occurred in about 1% of treated patients in a major trial. Serious harm is rare and has mostly been linked to unlicensed products and unregulated settings.

Aftercare that genuinely helps

• Do not rub, press or massage the treated area for the rest of the day.
• Skip strenuous exercise, saunas, steam rooms and facials until the next day.
• Leave make-up off the injection points for a few hours if you can.
• Paracetamol is usually fine for a mild headache; check with your prescriber about anything else.
• Contact the clinic promptly if you notice anything that worries you.

How much do anti-wrinkle injections cost in London?

In London, anti-wrinkle injections typically cost £180 to £280 for one area, £250 to £380 for two and £320 to £490 for three upper-face areas. Jaw slimming is usually £300 to £500 and underarm sweating £450 to £700. Prices are indicative and confirmed after assessment.

A useful way to judge value is cost per month of effect. Three upper-face areas at £400, lasting around four months, works out at about £100 a month; repeated three times a year that is roughly £1,200. Our cost guide to non-invasive facial rejuvenation compares this with fillers, skin boosters and energy devices.

Be cautious of prices far below these ranges. The UK government’s August 2025 announcement on cosmetic regulation specifically urged people to check a provider’s qualifications and insurance and to avoid treatments that appear suspiciously cheap. Ask whether the price includes a review appointment, and whether top-ups cost extra.

How to choose a safe anti-wrinkle injection prescriber in the UK

Choose a registered healthcare professional (GMC, NMC, GDC or GPhC) with specific aesthetic training who examines you in person before prescribing, uses a licensed product, works from a proper clinic, explains risks and costs in writing, and offers review and aftercare. Voluntary registers such as the JCCP and Save Face add reassurance.

UK regulation of non-surgical cosmetic procedures is still catching up. A House of Commons Library briefing notes that there are currently no specific legal controls on who can offer non-surgical cosmetic procedures, although botulinum toxin itself must be prescribed. Section 180 of the Health and Care Act 2022 allows the government to create a licensing scheme, and in August 2025 the Department of Health and Social Care confirmed that botulinum toxin, lip fillers and facial fillers will come under a new local authority licensing system, with the highest-risk procedures restricted to healthcare professionals working in CQC-registered providers.

Your checklist before booking

1. Check registration. Search the GMC (doctors), NMC (nurses), GDC (dentists) or GPhC (pharmacists) register, and ask about aesthetic training and experience.
2. Confirm a face-to-face prescriber. The GMC’s guidance for doctors who offer cosmetic interventions says injectable cosmetic medicines must not be prescribed by telephone, video link or online for patients the doctor has not examined.
3. Ask which product will be used and whether it is licensed in the UK. Ask to see the packaging.
4. Look at the setting. NHS advice warns against group treatments, events involving alcohol, voucher deals and mobile services in homes or hotels.
5. Ask about complications: what the common side effects are, what happens if something goes wrong and who you can call out of hours.
6. Get the cost in writing, including whether reviews and top-ups are included.
7. Take time to decide. A reputable clinic will not pressure you to book on the day.

Anti-wrinkle injections vs dermal fillers, skin boosters and resurfacing

Anti-wrinkle injections relax muscle movement. Dermal fillers restore lost volume and support. Skin boosters and polynucleotides improve skin quality, and resurfacing treats texture and etched lines. They solve different problems, which is why a well-planned result often combines two of them.

If your main concern is a hollow or deflated look, more toxin will not help and can make things worse. Our guide to dermal fillers in Knightsbridge explains how hyaluronic acid filler restores support and why it can be dissolved if needed. If your lines are fine, crepey and present at rest, start with our skin booster guide or the wider face treatments section.
