Lip filler aftercare is not just about reducing swelling. It is about giving your lips time to settle, protecting the treatment area and allowing your final result to develop as naturally as possible.
At L’Atelier Aesthetics on Harley Street, lip filler treatments are designed to enhance shape, hydration and proportion, rather than simply adding volume. Because of this, the way you care for your lips in the first few days can make a meaningful difference to comfort, healing and how confident you feel while the result settles.
Dr Duncan Brennand takes a considered, anatomy-led approach to lip filler, with every treatment planned around your existing lip shape, facial balance and personal preferences. Some swelling, tenderness and occasional bruising can be completely normal after treatment, especially because the lips are a delicate and highly vascular area.
This guide explains what to expect after lip fillers, what to avoid, how long swelling can last and when to contact the clinic for advice.
After lip filler, your lips may feel tender, swollen or slightly firm for the first few days. This is usually part of the normal healing process and does not mean that anything has gone wrong. For the first 24 to 48 hours, it is best to keep your aftercare simple. Avoid touching the lips unnecessarily, do not massage the area unless you have been specifically advised to do so, and avoid make-up around the mouth while the injection points are fresh. You should also avoid alcohol, strenuous exercise, saunas, steam rooms, sunbeds and very hot baths, as these can increase blood flow and make swelling or bruising more noticeable.
A gentle cool compress can be used if the lips feel uncomfortable, but ice should not be applied directly to the skin. Try to sleep on your back with your head slightly elevated on the first night, and avoid putting pressure on the lips while they are settling.
Most importantly, do not judge your final result too early. Lips often look fuller in the first few days because of swelling. The result usually softens and becomes more balanced over the following one to two weeks.
“The most important thing after lip filler is not to judge the result too early. Lips can swell unevenly in the first few days, which can make them look fuller, firmer or slightly asymmetrical before they settle. This is normal for many patients. I usually advise patients to give their lips around two weeks before assessing the final outcome. Good aftercare is simple: keep the area clean, avoid unnecessary heat or pressure, and contact the clinic if anything feels unusual.”
At L’Atelier Aesthetics, lip filler is not approached as a one-size-fits-all treatment. The aim is not to create a different mouth, but to improve definition, hydration, proportion and softness in a way that still suits your face.
This is why the recovery period matters. Your lips need time to settle before the true result can be assessed.
| Timing | What you may notice | What to do |
|---|---|---|
| Immediately after treatment | Lips may look fuller than expected and may feel numb, tender or firm. | Keep the area clean and avoid touching the lips unnecessarily. |
| First 24 hours | Swelling can increase. Mild bruising or redness may appear around injection points. | Avoid alcohol, exercise, heat, make-up and pressure on the lips. |
| Days 2 to 3 | Swelling may still be present and can sometimes look uneven. | Continue gentle aftercare. Do not judge the result at this stage. |
| Days 4 to 7 | Swelling usually starts to reduce and the lips begin to feel softer. | Normal routines can usually resume, but avoid anything that irritates the area. |
| Days 7 to 14 | The lips continue to settle and the final shape becomes clearer. | Contact the clinic if swelling, discomfort or asymmetry is worsening rather than improving. |
| Around 2 weeks | The result is usually more stable and predictable. | This is the best point to assess the outcome or discuss any refinement. |
Smoking (and vaping) is something we never recommend for our clients. Not only is it associated with a myriad of health concerns, but it also ages the skin and can disrupt the skin’s natural healing process and even cause an infection (for example, following microneedling treatment). We always advise against smoking after lip filler treatment for at least the first 24 hours.
It might be tempting to pop the champagne and toast your results, but alcohol can act as a blood thinner, which can make you more susceptible to bruising and swelling. Again, wait 24 hours before consuming alcohol.
Your lips may be sensitive to hot and cold temperatures, and thanks to numbing the lips, it can be harder to eat and drink straight after your treatment. Stick to easy-to-eat foods and drinks that don’t require you to wipe your lips, and avoid salty foods, which can make swelling worse and cause dehydration.
We suggest avoiding makeup in the first 24 hours after treatment. That’s because the area will be sensitive, and touching around the injection sites could cause pain, infection or product displacement.
Light exercise, such as walking, is fine – but avoid anything strenuous for at least the next couple of days. This helps prevent any existing swelling or bruising from worsening.
Heat treatments should be avoided for a couple of days after treatment, again because the swelling could worsen with the heat. This means no spa, sauna or sun bed treatment for around 48 hours.
Yes, you can take over-the-counter paracetamol. Blood thinners, such as aspirin, should be avoided, as these can lead to swelling and bruising. If in doubt about painkillers, or any other medication, ask us or your doctor.
Yes, depending on what these are. Dermal fillers and anti-wrinkle injections are fine, however, treatments such as microneedling or chemical peels may not be recommended. We can discuss this with you during your consultation and, if you’re looking to have multiple treatments, can advise when and which to have.
Yes, it’s possible to dissolve them if you’re unhappy with your results, however part of this process involves a consultation with us to ensure it’s the right choice for you. Bear in mind that your lips may take a few days to ‘settle’, so it’s a good idea to wait and see your results before making a decision.
This is a rare occasion with lip filler treatment and only happens with an inexperienced practitioner, or if the patient has some swelling or bruising following treatment. In most cases, lumps go away on their own, but it’s always worth having them checked in case there’s an underlying problem.
Do: keep the area clean, stay well hydrated, and use a cool compress gently if needed for comfort. Sleep on your back with your head slightly elevated if you can.
Avoid for 24 hours: alcohol, strenuous exercise, excessive heat (sauna/steam), and unnecessary pressure on the lips.
Avoid until swelling settles: sunbeds/strong UV, very hot environments, and anything that irritates the area.
Straight after treatment, you may notice swelling, tenderness and slight redness around the injection points. Bruising can happen too, especially if you bruise easily. These effects are usually temporary and tend to improve over several days.
You may also feel a little firmness in the lips at first. This commonly softens as swelling settles and the product integrates.
For the first day, keep things gentle. Avoid anything that significantly increases heat, blood flow or pressure on the lips, as this can make swelling feel more noticeable.
If you are planning other treatments, for example intense facials, peels or laser, around the same time, it is best to check with your clinician first so your skin has time to settle.
Straight after: lips can feel numb or tender, and swelling can start quite quickly.
Days 1 to 3: swelling is often most noticeable here, and bruising may appear or deepen slightly before it fades.
Days 4 to 7: lips usually start looking more like you, with swelling continuing to reduce.
Around 2 weeks: results tend to look more settled and predictable.
Everyone heals differently, and your clinician will advise what’s normal for you.
Mild swelling, tenderness and occasional bruising can be expected and usually improve over the first few days. Please contact the clinic if anything feels unusual, worsens rather than improves, or you are concerned at any point.
If you notice increasing pain, spreading redness, discharge, a fever, or any skin colour change that concerns you, seek advice promptly.
