So you've just had your lip filler appointment. Your lips look fuller, you're excited, and then the swelling kicks in. It's completely normal, and it doesn't mean anything has gone wrong. But knowing how to manage it well in those first 48 to 72 hours makes a real difference to how quickly you get back to looking and feeling like yourself.
Here's what actually works:
Why swelling happens after lip filler
When a needle or cannula passes through tissue, your body responds with inflammation. This is a normal healing response. Your immune system sends fluid and white blood cells to the area to begin repair. The lips are particularly prone to swelling because the tissue is delicate, highly vascular, and rich in nerve endings.
Most swelling peaks at around 24 to 48 hours post-treatment and then begins to settle. By day 5 to 7 the majority of swelling has resolved, though some subtle puffiness can linger for up to two weeks depending on the individual. Your injector will most likely have you scheduled for a follow up appointment in 2-4 weeks once the swelling has settled and the filler has integrated into the surrounding tissue.
What to do in the first 24 hours
Keep your head elevated
Lying flat allows fluid to pool in your face. For the first night, sleep with an extra pillow to keep your head slightly raised. It sounds simple but it genuinely makes a difference to how you wake up feeling the next morning.
Avoid heat
Heat increases blood flow and makes swelling worse. Skip the gym, hot showers, saunas, and anything that gets your heart rate up significantly for the first 24 hours. Sun exposure is also worth avoiding as UV on freshly treated skin isn't ideal.
Stay hydrated
Drinking plenty of water helps your body process inflammation more efficiently. Avoid alcohol for at least 24 hours as it dilates blood vessels and can increase both swelling and bruising.
Don't touch or massage the area
Unless your injector has specifically asked you to massage, which is sometimes recommended for certain procedures, leave the area alone. Touching, pressing, or manipulating the lips in the first 24 hours can displace filler before it has settled and can increase the risk for infection.
Ice packs: yes or no?
Ice can help reduce swelling by constricting blood vessels and numbing the area. If you use ice, wrap it in a cloth first and never apply ice directly to skin to reduce the risk of an ice burn. Use it for 10 minutes on, 10 minutes off, rather than continuously. Our lip shaped ice packs are the perfect size to use on your lips, freeze quickly and are reusable.
What to put on your lips after filler
This is where most people get it wrong. After lip filler, your lips need something that supports healing, not just moisture. Petroleum-based balms like Vaseline or Bepanthen create a barrier but don't actively support the tissue repair process.
Look for a lip balm specifically formulated for post-procedure recovery. Arnicare's arnica lip balm was developed by clinicians for exactly this purpose. It contains arnica montana, a botanical ingredient traditionally used to support recovery from bruising and swelling, along with ingredients that soothe and protect delicate post-treatment skin.
It's free from fragrances and irritants that don't belong anywhere near freshly injected lips, and it was formulated by a Registered Nurse and Nurse Practitioner who treat cosmetic patients in their own clinic.
Apply it gently from day one. It's safe for use directly on the lips and around the treated area.
What to avoid in the first week
Blood-thinning medications and supplements: if you haven't already stopped aspirin, ibuprofen, fish oil, or vitamin E, speak to your injector about timing.
Makeup on the lips: give the entry points time to close before applying lipstick or lip liner.
Dental appointments: avoid anything that requires you to hold your mouth open for extended periods in the first two weeks. The mouth also contains bacteria which can increase the risk of infection.
When to call your injector after lip filler
Swelling is normal. These things are not:
Pain that is worsening rather than improving after 48 hours. Skin that appears white, mottled, or changes colour dramatically. Any area that feels unusually hard. Vision changes or severe headache following treatment.
If you experience any of these, contact your injector immediately. Vascular complications from filler are rare but time-sensitive. Always err on the side of reaching out if something doesn't feel right. You can find out more about vascular occlusion here
The bottom line on swelling after lip filler
Swelling after lip filler is a normal part of the healing process and the vast majority of it resolves within a week. The best things you can do are keep your head elevated, avoid heat and alcohol, stay hydrated, and apply a post-procedure lip balm that actively supports recovery rather than just sitting on top of the skin.
Your results will look different at day 1, day 3, and day 14. Give it time before you judge the outcome, and if you have any concerns, your injector is always your first call.
