Lip filler aftercare: from the first hours to two weeks

Smooth recovery starts before the treatment

How easily the aftercare period goes depends partly on decisions made in the days beforehand. If you have an important event, a photo shoot or a long journey coming up, booking your treatment at least two weeks earlier gives the swelling time to settle and leaves room for a touch-up if needed.

• Share all the medicines and supplements you take at your consultation; some can make bruising more likely. Never stop a prescribed medicine on your own.
• Avoiding alcohol the day before and on the day of treatment may help reduce the chance of bruising.
• If you have an active cold sore, spot or wound on or around the lips, treatment will be postponed — just let us know before your appointment.

Day one: swelling is normal, and it isn't the final look

Straight after treatment your lips may look fuller than planned, and sometimes slightly uneven. This is not only the filler: it is the tissue's natural response to the needle or cannula, plus the effect of the local anaesthetic. The numbness wears off within a few hours. I'd encourage you not to judge the result in the mirror during these first hours.

• In the first hours, a cold compress wrapped in a clean cloth and applied on and off may help reduce swelling. Don't put ice directly on the lips, and don't press.
• Avoid touching the injection points, rubbing or massaging your lips; unless your physician specifically advises it, don't try to mould the filler yourself.
• Skip lip make-up on the first day; applying products before the injection points have closed can increase the risk of infection.
• Drinking through a straw and pursing your lips may feel uncomfortable on the first day; keep it to a minimum if you can.

Days 2–3: peak swelling, then it starts to settle

For many people, swelling is at its most noticeable on the morning of the second day; lying flat at night can make it worse. Sleeping on your back with your head slightly raised for the first few nights may help. If you have bruised, it usually fades through green and yellow tones within a week. You may feel small, soft lumps in the lips during this time; these are mostly related to swelling and tend to resolve on their own.

What to avoid in the first 24–48 hours

• Strenuous exercise and anything that makes you sweat heavily
• Saunas, steam rooms, sunbeds and very hot environments
• Alcohol (it can increase swelling and bruising)
• Sleeping face down or any position that puts pressure on your lips
• Long periods in strong sun

The first week: daily life, dental work and cold sores

Most people are back at work the day after treatment. In this first week there are two things I always mention. The first is dental work: procedures that stretch and pull the lips are often better scheduled a few weeks after filler, and we can plan the dates together at your consultation. The second is cold sores: if you have ever had a cold sore on your lips, be sure to tell us before treatment. Injections can trigger a cold sore in some people, and your physician may plan a preventive measure if it seems necessary.

Two weeks: assessing the final shape

Once the swelling has fully gone down and the filler has integrated with the tissue — usually at around two weeks — the true result becomes visible. Your review is timed to fall in this window. If there is slight asymmetry or an area that looks under-filled, this is when we decide whether a small touch-up is needed. Adding more product earlier is not recommended, because swelling can lead to the wrong decision.

Bringing photos taken in the same light straight after treatment and over the following days makes the review easier. They let us see together how the swelling progressed and how your lips reached their final shape. If you have travelled to Istanbul and gone home before the two-week mark, these photos also form the basis of a remote review as part of our follow-up for international patients.

First treatment versus repeat treatment

People having lip filler for the first time often find the swelling more striking, and it can take a few days to get used to the new look. For those who have had it before, the process is usually more familiar — but that is no reason to skip any stages. Especially if previous treatments were done by a different practitioner or with a different product, filler remaining in the tissue can affect how the new treatment settles. So with repeat treatments it is just as important to respect the two-week assessment period and to share everything you know about previous procedures. If there is filler build-up or a distorted shape in the lips, this may need to be addressed before any new product is added.

Which signs need a call straight away?

A rare but important complication of filler treatment is when the filler affects a blood vessel. Recognised early, it can be treated — so with any of the signs below, don't wait until the morning or your review appointment:

• Pain that keeps getting worse, doesn't ease, or is out of proportion
• Blanching (whitening) of the lip or surrounding skin, followed by a purplish or lace-like (mottled) discolouration
• Skin that feels cold, looks markedly pale or develops small blisters
• Blurred vision or any change in your vision (this is an emergency)
• Signs of infection such as fever or increasing redness and warmth

Afterwards: how long does lip filler last?

Because the lips move constantly, filler can break down faster here than in some other areas. How long it lasts depends on the product, the amount used and your metabolism; you'll find the details in how long do fillers last?. Fine lines around the outer lip often respond better to skin-quality treatments or a very low dose of toxin than to filler — we explain the difference in Botox vs fillers.
