Most of what decides how lip filler looks at week four happens in the first two days, and almost none of it is in the injector’s hands by then. Every patient leaves Vital Medical Care & Aesthetics with the same short checklist, and this post is that checklist with the reasons attached, because people follow rules better when they know what each one protects.
The direct answer: for the first 24 hours, ice in short sessions, stay upright, keep everything off the lips and skip alcohol, exercise and heat. For 48 hours, avoid pressure, saunas and hard training. Makeup and lipstick are fine from day two, normal exercise from about day five, and dental work and facials should wait two weeks. Call your injector promptly for increasing pain, pale or dusky skin or a spreading change in color. Candidacy, product and amount are set at the consultation with the physician.
The first 24 hours: the checklist
The first day is about letting the gel settle where it was placed and keeping swelling and bruising to a minimum. These are the eight things we ask every patient to do before they go to bed that night.
- Ice the lips for about ten minutes at a time, with a clean cloth between the ice and the skin, three or four times through the day. Short and repeated beats long and continuous.
- Stay upright for the first four hours, and sleep with your head raised on an extra pillow that night.
- Keep hands, straws, cups pressed to the lip, kisses and pillows off the lips. Pressure moves fluid and can move gel.
- No makeup, lip balm or lipstick on the lips today. The injection points are open for several hours and anything on them is a route for bacteria.
- No alcohol. It dilates blood vessels and worsens swelling and bruising.
- No exercise, no sauna, no hot yoga, no hot showers directed at the face. Heat and a raised heart rate both increase swelling.
- Drink water and keep food soft and low in salt. Chewing a large sandwich on numb, swollen lips is how people bite themselves.
- Take acetaminophen for discomfort if you need it. Avoid ibuprofen and aspirin for pain today unless your doctor has prescribed them, because they thin the blood and feed bruising.
Numbness from the lidocaine in the product wears off within an hour or two. Swelling will build through the evening and peak the next morning; that is expected. The treatment itself is described on our lip filler page.
Hours 24 to 48: the second day
Day two is usually the peak of swelling and the day bruises show, if they are going to. Continue to ice if it helps, keep the head raised at night, and keep alcohol, exercise and heat off the list for one more day. Lipstick and balm are fine from this point, once the injection points have closed, and a gentle lip balm actually helps because the surface of swollen lips dries out.
Do not massage, press or try to smooth any firm spots you can feel. They are areas of gel holding extra fluid, and they soften on their own over two weeks. Massaging before the gel has integrated is one of the ways filler gets pushed toward the border. If the physician specifically asks you to massage a particular spot, that is a different instruction and will be explained.
If a cold sore starts to tingle, start the antiviral you were given straight away. Patients with a history of cold sores are usually prescribed one to begin the day before treatment, because the needle can trigger an outbreak.
Days 3 to 7: easing back in
From day three the swelling drops noticeably each morning and the rules relax. Light exercise, a walk or an easy session, is fine from about day three. Harder training that raises the heart rate for a sustained period is better left until day five or later, since it can bring swelling back temporarily. Bruises are turning yellow by now and can be covered with makeup.
Sleep normally once the swelling is clearly on its way down, usually by night three or four. If you sleep on your stomach, keep using the extra pillow for the full week so your face is not pressed into the mattress.
By day seven most patients see roughly 80 to 90 percent of the final result. If anything still looks uneven, photograph it in the same light each day and bring the photos to the two week review. Our post on lip filler swelling stages explains what each day of that week typically looks like.
Week 2 and beyond: review, dental work, facials and flying
Two weeks is the earliest point to judge the result and the time we see patients back if a small adjustment is in question. It is also the point at which the remaining restrictions lift.
Dental work, including cleanings, should wait two weeks after lip filler. The mouth is stretched and pressed during dental treatment, and there is a small theoretical risk of bacteria from dental procedures reaching the gel; most injectors advise the same gap before and after. Facials, chemical peels, laser treatment and microneedling on or near the lips should also wait two weeks so the gel is fully integrated.
Flying is a frequent question. There is no strong evidence that cabin pressure affects filler, but the dry air and the hours of sitting can worsen swelling in the first two days, so if you can, book treatment at least 48 hours before a flight. A longer gap, a week or more, is sensible before an event you want to look settled for.
Beyond two weeks there are no rules, only the long game. How the result fades and when to top up is covered in our post on how long lip filler lasts; the short answer is six to twelve months for most patients, with a top up when about half the volume has gone and never within four weeks of a treatment.
What to avoid, for how long, and why
The waiting times below are the ones we use. They are typical of published aftercare guidance rather than fixed rules, and the physician may lengthen some of them for a patient who bruised heavily or had a larger amount placed. Botox has its own list, covered in our guide to what not to do after Botox.
| Avoid | How long | Why |
|---|---|---|
| Makeup, lipstick, balm on the lips | First 12 to 24 hours | Injection points are open; infection risk |
| Alcohol | 24 to 48 hours | Dilates vessels; more swelling and bruising |
| Exercise that raises the heart rate | 48 hours, hard training 5 days | Increases blood flow and swelling |
| Saunas, hot yoga, steam, hot showers on the face | 48 hours | Heat increases swelling |
| Pressure: massage, straws, kissing, face down sleep, tight masks | 48 hours, ideally a week | Can shift gel before it integrates |
| Ibuprofen, aspirin, fish oil, high dose vitamin E | Week before and 2 days after, unless prescribed | Thin the blood; more bruising |
| Dental work, facials, peels, lasers near the lips | 2 weeks before and after | Pressure and infection risk; gel still integrating |
| Flying | Ideally 48 hours | Dry air and sitting worsen early swelling |
| Smoking | As long as you can | Slows healing; pursing may shift gel |
Do not stop a blood thinner your doctor prescribed to prepare for filler. Tell the physician here instead, and the plan will account for it, which may mean accepting more bruising or choosing a different time.
Makeup, kissing, straws, sleep: the questions we hear most
When can I wear lipstick?
From day two, once the injection points have closed. Use a clean or new product; an old lipstick that has touched a cold sore in the past is a poor choice for freshly injected lips.
When can I kiss?
Gentle contact from day three, anything firmer from about a week. The concern is pressure on gel that has not yet integrated, not the kiss itself.
Can I use a straw?
Avoid them for 48 hours. Pursing hard around a straw works the lip muscle and presses the gel; drinking from a cup is easier on the lips anyway.
How should I sleep?
On your back with the head raised for the first two or three nights, and not face down for a week. Lying flat lets fluid pool in the face overnight, which is why lips look worst first thing in the morning.
Can I brush my teeth?
Yes, gently, from the first evening. Use a soft brush, avoid pressing the lips against the teeth and skip whitening strips for two weeks.
When to call: normal signs and warning signs
Normal after lip filler: swelling that peaks within 48 hours and then improves daily, bruising that fades over a week, tenderness, small firm spots in the first two weeks, lips that look uneven in the first few days, and mild itching. None of these need a call, though you are always welcome to make one. If you also take tirzepatide, our guide to tirzepatide side effects covers when to call about it.
Contact your injector promptly if any of the following appears: pain that increases after day one rather than easing; skin on or around the lips turning white, grey, dusky or blotchy, or a net like purple pattern spreading beyond the lips; swelling that keeps growing after day three; fever, spreading redness, warmth or pus; a firm lump still obvious past two weeks; or any change in your vision, which is extremely rare but an emergency. The first two are the signs of vascular occlusion, filler blocking or pressing on a vessel. It is uncommon and it responds well to prompt dissolving with hyaluronidase, which is exactly why it should never be waited out.
A different kind of change can appear months later: a soft shelf above the lip border, a blurred edge or a flattened upper lip. That is migration rather than an aftercare problem, and our post on lip filler migration explains how it is corrected.
Before you book: what to tell the physician, and where we are
Aftercare begins before the needle. Tell the physician at the consultation if you are pregnant, trying to conceive or breastfeeding, since filler is postponed in those cases. Mention any autoimmune condition, a cold sore or any infection near the mouth, previous filler and when it was placed, and any blood thinners, aspirin, fish oil or high dose vitamin E. Candidacy, product and amount are decided at that visit, and pricing is confirmed there; our price guide explains how the service is structured.

Questions readers ask
Can I take ibuprofen for pain after lip filler?
Acetaminophen is the better choice for the first two days. Ibuprofen and aspirin thin the blood slightly and can increase bruising. If a doctor has prescribed either for another condition, keep taking it and tell the physician here.
Is it normal for my lips to feel lumpy after filler?
Small firm spots in the first two weeks are common and are gel holding extra fluid at the injection points. They soften on their own. A firm lump still obvious at two weeks, or one that is painful or growing, should be reviewed.
How soon after lip filler can I go to the gym?
Light activity from about day three, harder training from day five. Sustained high heart rate in the first 48 hours increases swelling and can bring it back on day three or four.
Should I massage my lips after filler?
No, unless the physician has asked you to for a specific spot. Massaging gel that has not integrated can push it toward the lip border. Firm areas soften by themselves within two weeks.
