Anti-Wrinkle Injection Aftercare: Which Rules Are Real and Which Are Folklore
Last updated: September 2026
You have just had anti-wrinkle injections, and you are handed a list.
- Do not lie down for four hours
- Do not bend over
- Do not pull facial expressions
- Do not exercise
- Do not fly
- Do not touch your face
The list is delivered with total confidence, it varies from clinic to clinic, and almost nobody mentions the interesting part: hardly any of it has ever been tested.
That is not a criticism of the clinics handing it out, mine included. Sensible precaution in the absence of evidence is a reasonable way to practise. But patients deserve to know which category each instruction falls into, because the difference between "this is proven" and "this is cautious guesswork" changes how much you should worry when you accidentally lie down at hour three.
So here is the honest version: what the trials show, what survives on mechanism alone, and the one thing that actually determines your result.
Key Takeaways
| The rule | What the evidence actually shows |
|---|---|
| Stay upright for four hours | No trial has tested it. A 2025 study of 5,014 patients with no such restriction reported zero cases of eyelid droop |
| Do not pull facial expressions | The opposite, if anything. A randomised trial found deliberate muscle exercise brought results forward by 1 to 2 days |
| Do not rub or massage | Also untested, but mechanistically sensible and near-universally advised. The one I would still follow |
| Do not bend over, fly or exercise | No published evidence. Precaution, not science |
| What actually matters? | Dose, dilution, placement and the anatomical knowledge of whoever is holding the needle |
| Should I panic if I broke a rule? | No. The evidence does not support the level of anxiety these lists create |

Why Are We Told to Stay Upright?
The worry behind the rule is migration: the idea that the product could travel from where it was placed and weaken a muscle nobody intended to treat. The feared outcomes are a heavy brow or, worse, a drooping upper eyelid.
That is a legitimate thing to want to avoid. A droopy lid is not dangerous, but it is distressing, it can last weeks, and there is very little to be done about it once it happens.
The logic then runs: gravity pulls things downward, so if you lie down or bend over, the product might travel. Stay upright and you are safe.
It is intuitive. It is also based on a picture of how these injections behave that is not quite right.
Migration Versus Diffusion, and Why It Matters
The product does not sit in the muscle as a small pool of liquid that can slosh about. It does not behave like ink dropped into water.
What actually happens is diffusion: a small amount of local spread from the injection point into the immediately surrounding tissue, over a short period, after which the active component is taken up by nerve endings and is no longer free to move anywhere.
That uptake is rapid. Within a relatively short window the question of whether you are standing, sitting or lying down has become irrelevant, because there is nothing mobile left to move.
How far that initial local spread reaches is influenced by things decided before you leave the treatment room:
| Factor | Why it matters | Who controls it |
|---|---|---|
| Dose | More units in one spot means more spread from that spot | Your injector |
| Dilution and volume | A larger volume of fluid occupies more space and spreads further | Your injector |
| Placement | How close the injection sits to structures you do not want affected | Your injector |
| Anatomical knowledge | Knowing where the muscles you must avoid actually sit in your face | Your injector |
| Your posture afterwards | Far less than any of the above | You |
Almost every factor that determines whether you get an unwanted result is decided before you stand up. The aftercare list puts the responsibility on you for something that was largely settled in the chair.
What the Evidence Actually Says About Staying Upright
Here is the honest position: there is no clinical trial demonstrating that staying upright after cosmetic injections improves outcomes or prevents complications. Not a weak trial. None.
The largest relevant dataset was published in Toxins in 2025. It was a retrospective study across six Italian centres covering 5,014 patients treated in the upper face. Rather than the usual list of restrictions, patients followed only a supervised 10-minute observation period immediately after treatment, with no extended behavioural instructions at all.
Among the 4,000 who attended two-week follow-up:
| Outcome | Result |
|---|---|
| Upper eyelid droop | Zero cases |
| Overall adverse events | 5.99% |
| Mild bruising | 3.0% |
| Temporary headache | 1.8% |
| Eyebrow droop | 0.4% |
| Dry eyes | 0.3% |
| Satisfied or very satisfied | 90% of the 2,010 surveyed |
"Our findings indicate that omitting extended post-injection instructions does not negatively impact patient satisfaction or complication rates."
— Santorelli A et al., Toxins. 2025;17(8):372
Why I am not going to overstate this
The authors are admirably clear about what their study cannot do, and I am going to be equally clear, because this is exactly the sort of finding that gets oversold online.
It had no control group. Nobody was randomised to the restricted protocol for comparison. It carried out no statistical analysis. And it followed patients for two weeks only.
So this is not proof that restrictions are useless. It is a large, real-world observation that thousands of people had no extended restrictions and nothing bad happened, which is meaningful in a field where the alternative evidence is precisely nothing.
A 2018 review in the Journal of Aesthetic Nursing reached a similar conclusion from the other direction, finding that most standard post-treatment instructions, including avoiding lying down and bending, have no published evidence behind them at all.
So Why Do Clinics Still Advise It?
Three honest reasons.
- It costs nothing and risks nothing. Sitting up for a couple of hours harms nobody. In the absence of evidence either way, the cautious option is defensible
- Nobody wants the "what if". If a patient develops a droopy lid and you gave no advice, you will always wonder. That is a powerful motivator, and it is about the practitioner's peace of mind as much as the patient's outcome
- It has been passed down. Much aftercare guidance is inherited from training, from colleagues, from the way things have always been done, and is rarely revisited
Major medical sources do still advise avoiding lying down for a short window, typically two to four hours, as a precaution. That is a reasonable position and I am not going to tell you they are wrong.
My view: staying upright for a couple of hours is sensible belt-and-braces advice. It is precautionary, not proven. If you follow it, good. If you fall asleep on the sofa at hour two, you have not ruined anything, and you should not spend a fortnight worrying about it.
That distinction is the entire point of this article. There is a meaningful difference between advice given because it is known to help and advice given because it might, and patients are rarely told which they are receiving.
The Facial Expression Rule, and Why It May Be Backwards
This is the genuinely surprising one.
The instruction "do not pull faces" is widespread. The only randomised trial to look at the question found the opposite of what that instruction implies.
A randomised, controlled, crossover trial published in the Journal of the American Academy of Dermatology in 2019 tested whether deliberate facial exercise after injection affected how quickly results appeared in the forehead and frown area.
| Detail | What the trial involved |
|---|---|
| Participants | 22 women, aged 27 to 66 |
| The regimen | Three sets of 40 repetitions of forehead raises and frowns, at 10-minute intervals, over four hours |
| Onset | Visible improvement 1 to 2 days earlier in the exercise group |
| Statistical significance | Reached by day 3 (p=0.02) |
| Result at two weeks | Identical in both groups |
| How long it lasted | Identical in both groups |
Two things worth being precise about, because this study gets misreported.
First, it is a small trial. Twenty-two people is enough to detect a clear effect and not enough to settle a question.
Second, it brings the result forward. It does not improve it. By two weeks the exercisers and non-exercisers looked the same, and their results lasted the same length of time. So this is not a technique for getting a better outcome. It is, at most, a way of seeing your outcome slightly sooner.
And third, what was tested was 120 deliberate repetitions over four hours, not ordinary facial expression. The trial does not tell us that talking, smiling and raising your eyebrows do anything at all.
But it does tell us something useful: if a protocol of deliberately contracting the treated muscles 120 times does not harm the result, then having a conversation and laughing at something is not going to either.
What I actually tell patients
- Normal facial expression is entirely fine. Talk, smile, frown, react to things. You do not need to hold your face still
- You do not need to do the exercises either. They may bring things forward a day or two. They will not improve your result
- What to avoid is pressure, not movement. Those are different things and the standard advice runs them together
The One Rule I Would Still Follow, and Why It Is Weaker Than You Think
The advice not to rub or massage the treated area is close to universal, and it is the one I still give.
The reasoning is mechanistic and sound. In the short window before uptake is complete, firm pressure and massage could in principle encourage spread into muscles you did not want treated. Rubbing also irritates injection sites and makes bruising more likely, which is a small but real reason on its own.
But I am not going to tell you it is proven, because it is not. The 2018 review I mentioned earlier lists avoiding massage among the instructions that lack published evidence, alongside avoiding strenuous activity, bending, air travel and cold compresses. The only two recommendations that review found any support for were exercising the treated muscles and using sun protection.
So the honest summary of anti-wrinkle injection aftercare is this: almost none of it has been tested. What survives does so on plausible mechanism and clinical consensus. That is a perfectly reasonable basis for advice. It is just not the same thing as evidence, and you are entitled to know the difference.
The practical version of the rub rule: touch yes, rub no. Applying your usual skincare gently is fine. Pressing, kneading, using a facial tool or having someone massage your face is not.
Realistic Aftercare, in Plain Terms
| Timeframe | What I would actually do | Evidence status |
|---|---|---|
| First few hours | Avoid rubbing, massaging or pressing firmly on the treated areas. That includes facial tools, firm make-up application and tight headwear or goggles | Mechanism and consensus, not trial data |
| First few hours | Stay reasonably upright if it is convenient. If you end up reclining, do not worry about it | Precaution only. No trial evidence |
| Facial expression | Behave normally. No need to hold still | Supported. Deliberate exercise did no harm and sped onset slightly |
| First 24 to 48 hours | Keep skincare gentle. Cleanse softly, pat dry, go easy on strong actives if your skin is sensitive | Sensible, and reduces irritation at injection sites |
| First 24 to 48 hours | Skip facials, face massage, microneedling and anything involving pressure on the area | Precaution, and avoids confusing a reaction with a complication |
| Ongoing | Daily broad spectrum sun protection | One of only two recommendations with supporting evidence in the literature |
| Exercise, bending, flying | No published evidence against any of them. Use your judgement | Folklore |
| Alcohol | May increase bruising. Worth moderating on the day, for that reason alone | Plausible, not specifically studied here |
What Genuinely Determines Your Result
If you take one thing from this article, take this. The aftercare list is not where your result is decided.
| What matters | Why |
|---|---|
| Anatomical knowledge | Faces differ. Muscle position, size and strength vary between people, and treating a template rather than a face is how unwanted results happen |
| Assessment before the needle | Watching your face move, at rest and in expression, before deciding anything |
| Dose and placement | The two variables that most strongly influence both your result and the risk of affecting something unintended |
| Dilution and volume | More fluid means more spread. This is a deliberate choice, not an accident |
| Knowing when to do less | Or nothing at all. The most useful skill and the least marketable one |
| Being reviewed properly | A follow-up appointment where results are assessed and next time is adjusted accordingly |
Every item on that list belongs to your practitioner. That is why the question worth spending time on is who is treating you, not whether you can sit upright for four hours afterwards.
When to Seek Urgent Medical Help
Most side effects are mild, temporary and self-limiting: small bumps at the injection sites, tenderness, light bruising, occasionally a headache for a day or two.
Seek urgent medical attention if at any point after treatment you develop:
- Difficulty breathing
- Difficulty swallowing
- Difficulty speaking
- Muscle weakness away from the treated area
- Signs of a severe allergic reaction: widespread hives, swelling of the face or throat, wheeze, feeling faint
These are rare. They are also the reason treatment should be carried out by a qualified medical professional who can be contacted afterwards and who knows what to do. Do not wait to see whether it settles.
For anything less urgent, such as an asymmetry, a heavy brow or a result you are unhappy with, contact whoever treated you. That is what a review appointment is for.

| Honest advice about whether treatment is right for you at all | A diagnosable medical condition affecting your skin or face |
| Explaining which aftercare advice is evidence based | Anything that is not purely cosmetic |
Frequently Asked Questions
Will lying down ruin my results?
There is no trial evidence that a short lie-down affects anything, and a study of over 5,000 patients treated with no such restriction reported no cases of eyelid droop. Sitting up for a couple of hours is reasonable precaution. It is not a rule you need to fear breaking.
Do I need to avoid facial expressions?
No. Normal movement is fine. The only randomised trial on the subject found that deliberately exercising the treated muscles brought results forward by a day or two and did no harm.
Should I do the facial exercises then?
You can if you want to see your result a little sooner. It will not make the result better or longer lasting. The trial found both groups identical at two weeks.
What is the one thing that really matters?
Not rubbing or massaging the area in the first few hours, and choosing an injector who understands anatomy, dosing and placement. The second matters far more than the first.
Can I exercise afterwards?
There is no published evidence that exercise affects the result. Many clinics advise waiting 24 hours, which is precaution rather than data. If you are going to the gym, bear in mind that flushed, sweaty skin makes bruising at injection sites a little more likely.
Can I fly afterwards?
No published evidence suggests otherwise. The advice against flying within 24 hours is another inherited instruction with nothing behind it.
Can I wear make-up?
Yes, but apply it gently and preferably later the same day. The concern is the pressure of a brush or sponge on the area, not the make-up itself.
How long until I see anything?
Typically 3 to 5 days for the first changes, with the full result at around two weeks. That two-week point is when your result should be assessed, not before.
I broke one of the rules. Should I be worried?
Almost certainly not. Given how little evidence sits behind most of these instructions, the anxiety they generate is out of proportion to the risk. If something genuinely concerns you, contact whoever treated you rather than searching online at midnight.
Why do different clinics give completely different advice?
Because in the absence of evidence, everyone falls back on what they were taught and what feels safe. That is precisely why the lists vary so much from place to place, and it is worth knowing when you are comparing them.
