Lip filler aftercare: what to expect in the first two weeks

Most people judge their lip filler in the bathroom mirror the morning after treatment. It is the least reliable moment to do it. What you’re looking at in the first few days is mostly swelling, and swelling is rarely even. Lips that look too big, lopsided, or lumpy on day two are usually showing you how your tissue reacts to injections rather than what the result will be.

That distinction shapes what aftercare is for. Looking after your lips in the first fortnight won’t change where the filler was placed or how much was used. Its job is to keep swelling and bruising down, lower the risk of infection, and leave the filler undisturbed while it settles.

The first 48 hours

Expect swelling, tenderness, and possibly some bruising. Lips have a rich blood supply and swell more readily than most other areas of the face. Swelling is usually at its worst over the first two to three days and often looks most pronounced first thing in the morning.

A cool compress wrapped in a clean cloth and held gently against the lips for a few minutes at a time can help. Don’t put ice directly on the skin and don’t press. Sleeping with your head slightly raised for the first night or two helps as well.

Keep your hands away from your lips and skip lipstick and other lip products for the first 24 hours, while the injection points close. For the first day or two, avoid anything that raises blood flow to the face or puts pressure on the lips. That means strenuous exercise, alcohol, saunas, spa pools, very hot showers, and firm pressure such as kissing or sleeping face down.

If you need pain relief, ask us what is suitable for you. Some common anti-inflammatory medicines can make bruising worse, and you shouldn’t stop any prescribed medicine without talking to your doctor first.

Days three to fourteen

Swelling eases noticeably through the first week. Bruising, if you have any, can take a week or more to fade. It is common to feel small firm areas when you press your lips together or run your tongue across them. As long as they are getting softer rather than larger or more painful, this is part of settling and generally resolves within a couple of weeks.

Resist the urge to massage or press on them unless we have specifically asked you to. It is also sensible to leave facials, non-urgent dental work, and other treatments around the mouth until the two-week mark.

If you get cold sores

Injections around the mouth can trigger a cold sore in people who are prone to them. Tell us at your consultation if you have ever had one, because it is far easier to plan around beforehand than to manage afterwards. If you feel the familiar tingle after treatment, contact us rather than waiting to see what happens.

What isn’t normal

Serious complications from lip filler are uncommon, but they are time-critical, so it is worth knowing the signs. Contact us straight away if you notice pain that is severe or getting worse instead of better, skin on or around the lips that turns white, grey, or a dusky, blotchy purple, or swelling, redness, and heat that increase after the first few days, particularly with a fever or any discharge.

These can point to a problem with blood supply to the skin or to an infection, and both need to be assessed promptly. If you can’t reach us, seek urgent medical care. Any change in your vision after filler is an emergency, and you should call 111.

If you’re unsure whether you are looking at an ordinary bruise or something else, contact us. We would much rather check twenty ordinary bruises than miss one problem.

When to judge the result

Wait two weeks. Before then you are assessing swelling. At two weeks the lips have settled enough to see their shape and volume properly, and that is the point at which any adjustment is worth discussing. Hyaluronic acid filler can be added to or dissolved if needed, but those decisions belong on settled lips, not swollen ones.

This is also why lip filler is the wrong choice in the fortnight before a wedding, a photo shoot, or any event where you need to look a particular way. Nobody can predict how much you will swell or bruise, and good aftercare reduces both without removing either. If you have something important coming up, book well ahead of it or wait until afterwards.

If you have questions about your own recovery, contact the clinic. If you’re considering lip filler and want to talk through timing first, book a consultation.
