When getting lip fillers for the first time, you’ll start with a consultation, then have numbing cream applied before small injections shape your lips. The treatment takes around 30–40 minutes, results show immediately, and swelling settles within 48 hours—with the final look revealed after about a week.

So, you’ve been thinking about lip fillers. Maybe you’ve saved a few photos, maybe you’ve spent one too many late nights scrolling through before-and-afters, and maybe you’ve talked yourself in and out of it a dozen times already. If that sounds familiar, you’re in good company—and you’re in exactly the right place.

Getting lip fillers for the first time can feel a little daunting, especially with all the mixed messages floating around online. Will it hurt? Will you look overdone? What actually happens when you sit in that chair? These are the questions we hear all the time at Nurse Hannah Clinic in South Woodford, London, and they’re completely valid ones to ask.

In this guide, I’ll walk you through the whole journey—from your consultation and the numbing process, right through to treatment time, the swelling timeline, and your final results. By the end, you’ll know exactly what to expect, and hopefully feel a lot calmer about the whole thing.

Is it normal to feel nervous before lip fillers?

Absolutely. In fact, if you weren’t a little nervous, I’d be surprised. Lip fillers are a big first step, and it’s natural to feel a mix of excitement and butterflies.

Here’s the thing though—a lot of that anxiety comes from Googling at 1am and stumbling across the scariest photos the internet has to offer. Those dramatic “duck lip” results you’ve seen? They’re rarely the norm, and they’re certainly not what we’re aiming for.

At Nurse Hannah Clinic, our whole approach is about enhancing your features, not changing them. We want you to look like you—just refreshed and a little more confident. Once you understand what’s actually involved, most of those nerves tend to melt away.

What you should know before getting lip fillers

Lip fillers aren’t a one-size-fits-all treatment, and that’s a good thing. Some people want a subtle hydration boost, others want a touch more volume, and some simply want to even out lips that have always been a little uneven. Check our blog.

Lip fillers are made from hyaluronic acid, a substance your body produces naturally to keep skin and lips hydrated and plump. As we age, those levels drop, which can leave lips looking thinner or less defined. Filler gently restores that lost volume without changing how your lips feel.

There are a few things worth knowing before you book:

• Natural is the goal. Good lip enhancement should look balanced and proportionate to your face—never puffy or obvious.
• Suitability matters. Lip fillers generally aren’t recommended if you’re pregnant or breastfeeding, or if you have an active cold sore. Certain medications and medical conditions can affect suitability too.
• Honesty helps. A proper consultation lets us talk through your health history and make sure the treatment is right for you.

If you’re not sure whether you’re a good candidate, that’s exactly what a consultation is for.

Do I need to prepare for lip fillers?

Yes, a little preparation goes a long way—and none of it is complicated. Here’s a simple checklist to help you get ready:

• Skip the alcohol the day before, as it can increase the risk of bruising.
• Be cautious with blood-thinning supplements like fish oil or vitamin E, but always check with your GP or pharmacist before stopping any medication.
• Come makeup-free if you can, or expect to have your lips gently cleansed on arrival.
• Mention any cold sore history—we may recommend an antiviral to reduce the chance of a flare-up.
• Eat beforehand so you feel comfortable, and try to keep your day fairly relaxed afterwards.

Nothing here needs to throw your schedule into chaos. A bit of common-sense prep just helps your lips settle more smoothly.

Your consultation: what happens and what we discuss

Every treatment at Nurse Hannah Clinic starts with a proper consultation—and I genuinely believe it’s the most important part of the whole process.

This is where we sit down together and talk through what you’re hoping to achieve. Do you want a little more volume? Better definition? A smoother, more hydrated texture? There are no silly questions here, and there’s absolutely no pressure to commit to anything on the spot.

During your consultation, I’ll:

• Discuss your goals and the lip shape you’re drawn to
• Assess your facial balance, always with a focus on enhancing your features rather than changing them
• Go through your medical history, the risks, consent, and aftercare
• Create a personalised treatment plan, including how much filler to use and whether a staged approach might suit you better

If you’re not sure what you want yet, that’s completely fine. That’s precisely what a free consultation is for.

The lip filler process, step by step

Once you’re happy to go ahead, here’s how the lip filler process actually unfolds.

Cleansing and prep

First, I’ll gently cleanse the area to make sure everything is clean and ready. Sometimes I’ll mark the lips lightly to plan where the filler will go, keeping your natural shape in mind.

The numbing process (and what it feels like)

Comfort is a big priority, so a topical numbing cream is applied before we begin. Many of the fillers we use also contain a local anaesthetic called lidocaine, which adds another layer of comfort as we go.

Most clients tell me the sensation is more of a pressure or a quick pinch than actual pain. And if you ever need a moment, just say so—we can pause at any time. Communication is encouraged throughout, and there’s no rushing.

Treatment time

The injecting part itself is surprisingly quick, but the full appointment usually takes around 30 to 40 minutes. First-timers sometimes take a touch longer, simply because we build in extra time for questions and to make sure you feel completely at ease. There’s no clock-watching here.

Immediately after: swelling, bruising

Here’s something worth preparing for: your lips will look swollen straight after treatment. This is completely normal, and it’s not the final result.

You might glance in the mirror and see a much larger swelling than expected. This is just your body’s natural response to being injected, and hyaluronic acid draws in a bit of water too. Your lips may feel firm, a little tender, and possibly slightly uneven at first. They shouldn’t be genuinely painful, though a bit of soreness is normal.

Trust me, this stage passes quickly.

Swelling timeline: a day-by-day guide

Everyone heals slightly differently, but here’s a general idea of what to expect:

• Day 0: Swelling begins and your lips may feel tender. This is peak “fresh out of the chair” territory.
• Days 1–3: Swelling often peaks around now, and you might notice some light bruising. This is the stage where lips can feel firm or look a little bigger than planned.
• Days 4–7: Things start settling, and your lips begin to look more like you.
• Weeks 2–4: The filler fully settles and you’ll see your true, final result.

A word on safety: some swelling and bruising is completely normal. But if you ever experience severe or increasing pain, blanching (whitening) of the skin, intense heat, or a fever, get in touch with us straight away. We’ll always tell you what’s normal for you—and what isn’t.

Aftercare tips to help your lips settle nicely

A little aftercare makes a real difference. Here are the key do’s and don’ts:

• Avoid touching or applying makeup to your lips for 24 hours.
• Skip strenuous exercise for the first day or two, as it can worsen swelling.
• Stay away from heat—think saunas, hot yoga, and sunbeds—for a few days.
• Give alcohol a miss for a short while to reduce bruising.
• Don’t massage your lips unless I’ve specifically told you to.
• Use a gentle cool compress if you’d like to ease any swelling.

You’ll get personalised aftercare advice at your appointment, so you won’t be left guessing.

When you’ll see results (and how long they last)

You’ll notice an improvement immediately, but remember—those early days include swelling, so your true result appears once everything settles after about a week.

Results typically last between 6 and 12 months, depending on the product used and your own metabolism. First-timers sometimes find their body breaks down filler a little faster at first, which is completely normal. A top-up treatment down the line helps keep your lips looking hydrated and defined.

And if you’re nervous about going too far, a staged approach is a lovely option. We can start subtle and build gradually, so you stay in control every step of the way.

Frequently asked questions

Do I need to prepare for lip fillers?
A little prep helps. Avoid alcohol and blood-thinning supplements beforehand (check with your GP first), arrive makeup-free if possible, mention any cold sore history, and eat before your appointment.

How long does the lip filler process take?
The full appointment usually takes around 30 to 40 minutes, including consultation time. First-time treatments may take slightly longer to allow for questions.

How long will my lips be swollen after filler?
Most swelling fades within 48 hours, though some lingers for a few days. Your final result typically settles after about a week.

Does the numbing process actually work?
Yes. A topical numbing cream is applied before treatment, and many fillers also contain lidocaine. Most clients describe the sensation as a mild pinch or pressure rather than pain.

Will lip fillers look natural on me?
They should. Our approach focuses on subtle enhancement that complements your features—refreshed, not overfilled.

How soon can I wear lipstick again?
It’s best to avoid makeup on your lips for the first 24 hours to keep the area clean while it settles.

What are the signs something isn’t right after filler?
Contact us if you notice severe or increasing pain, blanching of the skin, unusual heat, or a fever. Normal swelling and mild bruising, however, are nothing to worry about.

How long do results last?
