Anti-wrinkle aftercare: the first 24 hours

How anti-wrinkle injections actually work

Before explaining the aftercare rules, it helps to understand what's happening beneath your skin. Botulinum toxin works by binding to the presynaptic surface of neurons — specifically, the nerve terminals that use acetylcholine, the neurotransmitter responsible for telling muscles to contract. Once bound, the toxin prevents acetylcholine from being released, which means the nerve signal never reaches the muscle.

This binding is irreversible. The muscle doesn't receive the instruction to contract, so it relaxes. Over time — typically three to four months — your body generates new nerve terminals, acetylcholine release resumes, and movement gradually returns. This is why anti-wrinkle treatment isn't permanent: it metabolises naturally, and you're back where you started.

The binding process doesn't happen instantly. After injection, the toxin needs time to reach the nerve terminals and attach properly. The paralytic effect typically begins within 24 to 72 hours and reaches full strength over the following one to two weeks. Your aftercare during those first 24 hours protects this binding window.

Hour by hour: what to do and why

The first hour

Immediately after your treatment, you'll have small puncture marks at each injection site. These close within minutes. You might notice slight redness or the beginning of minor swelling — both are normal inflammatory responses to any needle. Some clients see nothing at all.

During this first hour, the injected product is settling into the muscle tissue. Resist the temptation to check by touching. Your hands carry bacteria, and while infection from anti-wrinkle injections is rare, there's no reason to increase the risk. More importantly, pressing on the area can theoretically disperse the product beyond the intended muscle.

Hours one to four

This is the critical window. The toxin is actively diffusing through the muscle tissue and beginning to bind to nerve terminals. Three main rules apply:

• · Stay upright. Lying down or bending forward can encourage the product to migrate away from the injection site, potentially causing uneven results or affecting unintended muscles. Four hours upright is the standard recommendation across most clinics and manufacturers.
• · Don't massage or rub the area. Facial massage, vigorous skincare application, or simply pressing on the treated zones can spread the toxin beyond the targeted muscle. This is particularly important around the eyes, where migration can affect the muscles that lift the eyelid.
• · No strenuous exercise. Hard physical activity increases blood flow throughout your body, including to your face. Increased circulation around the injection sites may disperse the product before it has properly bound. Light walking is fine; spin class is not.

Some practitioners allow lying down after two hours; others recommend the full four. I advise clients to stick with four hours where practical. It's a small inconvenience for peace of mind about your results.

Hours four to twelve

By this point, you can lie down normally — including sleeping. Continue avoiding strenuous exercise and direct pressure on the treated areas. If you normally have a facial in the evening after work, reschedule it. If you have a massage booked that involves lying face-down on a headrest, postpone that too.

You can wash your face gently with your usual cleanser. Apply skincare products without pressing hard. Makeup can be worn if needed, though I generally recommend waiting until the next morning — partly to avoid touching the area repeatedly, partly because any residual redness is easier to manage after a night's rest.

Hours twelve to twenty-four

By the twelve-hour mark, most of the settling has occurred. Continue avoiding intense exercise until 24 hours have passed. You can sleep on your side or however feels comfortable — the upright rule was specifically for the first four hours.

Don't expect to see results yet. Onset typically takes 24 to 72 hours, with full effect developing over one to two weeks. Looking in the mirror at hour twelve and worrying that nothing has happened is entirely normal — nothing is supposed to have happened yet.

Why each rule exists

Don't lie down: preventing migration

Gravity affects everything in your body, including injectable products. When you lie flat or bend forward shortly after treatment, you create conditions where the toxin could potentially track away from the injection site. The concern isn't dramatic migration across your face — it's subtle movement that could mean slightly less product where you want it and slightly more where you don't.

Around the forehead and frown lines, migration toward the brow could theoretically contribute to brow heaviness. Around the eyes, it could affect the levator muscle and contribute to temporary eyelid drooping. These complications are rare regardless, but the four-hour upright rule reduces the risk further.

Don't massage: keeping the product localised

As the Cleveland Clinic puts it: "We ask people not to massage the area because we don't want to diffuse the Botox." The toxin is injected into specific muscles at specific depths. Manual pressure can spread it to adjacent muscles, which may then also weaken — not always in ways you'd want.

This doesn't mean you need to treat your face like glass. Gentle cleansing is fine after the first few hours. But avoid anything that involves sustained pressure: gua sha, jade rolling, facial massage, sleeping face-down on a firm pillow. The 24-hour window gives the product time to bind securely so that subsequent touching won't affect placement.

Don't exercise hard: controlling blood flow

Strenuous exercise increases circulation throughout your body, including to your face. The theory is that heightened blood flow around newly injected toxin could encourage dispersal before proper binding occurs. Some practitioners also note that increased blood flow may contribute to bruising at injection sites.

I'll be honest: the clinical evidence here is less robust than for the other rules. Some doctors argue there's little proof that exercise significantly affects outcomes. My view is that 24 hours without intense exercise is a minor sacrifice, and if there's any protective benefit at all, it's worth taking.

What you can do in the first 24 hours

The restrictions get the most attention, but plenty of normal activities are fine:

• · Work at a desk, attend meetings, drive — anything that keeps you generally upright.
• · Eat and drink normally. There are no dietary restrictions.
• · Take paracetamol if you have any discomfort, though most clients don't need it.
• · Gentle walking and light activity — the exercise restriction applies to strenuous workouts, not moving about your day.
• · Watch television, read, work on your laptop — rest is fine as long as you're not lying flat for the first four hours.

After the first 24 hours

Once 24 hours have passed, most aftercare restrictions lift. You can exercise, have facials, sleep however you like. The toxin has had time to bind, and normal activities won't affect your results.

Over the following days, you'll start to see the effect emerge. Some people notice softening of movement within 24 to 72 hours; for others, it takes closer to a week. The full result develops over one to two weeks. I ask clients to return for a review at the two-week mark so we can assess the outcome and make any adjustments if needed.

Results typically last three to four months, though individual variation is normal. Some clients find their results last longer with repeated treatment over time; others metabolise the product more quickly. We'll discuss your specific pattern at your review appointments.

A short safety note

You may have seen recent news coverage of a botulism outbreak in England linked to unlicensed botulinum toxin products. Between June and August 2025, 41 confirmed cases were reported — a stark reminder that not all practitioners use legitimate, MHRA-licensed products. Testing of seized products found potency levels significantly higher than labelled.

At Visage Aesthetics, I use only MHRA-licensed botulinum toxin products. I hold a valid NMC registration and prescribing qualification. Under new NMC guidance effective from June 2025, nurse prescribers are required to consult face-to-face before prescribing non-surgical cosmetic medicines — a standard I've always maintained. Your safety starts with knowing who is treating you and what they're injecting.

Questions clients often ask

Can I drink alcohol? There's no direct interaction between alcohol and botulinum toxin, but alcohol can thin the blood slightly and may increase bruising risk. I suggest avoiding it on the day of treatment if you're prone to bruising.

Can I fly? Yes. Cabin pressure doesn't affect the product. If your flight is within the first four hours, just stay upright in your seat rather than reclining fully.

Can I have other treatments the same day? I recommend spacing treatments out. If you want microneedling, chemical peels, or laser work, do those at least two weeks before or after your anti-wrinkle treatment.

What if I accidentally lie down or touch my face? Don't panic. These guidelines reduce risk; they don't guarantee problems if broken. One brief moment of touching your forehead won't ruin your results. Just return to the guidance as best you can.
