Let’s Talk Lip Fillers — Everything You’ve Wanted to Know

So, let’s start with the basics! What exactly are lip fillers, and how do they work?

Lip fillers are gel-like substances — most commonly made from hyaluronic acid (HA) — that are injected into the lips to add volume, definition, and hydration. Hyaluronic acid is actually something your body naturally produces, so it’s pretty safe and biocompatible. The filler works by attracting water molecules to the injected area, which gives the lips a soft, plump, and smooth appearance. Depending on the brand and formulation, results usually last between 6 to 12 months before your body gradually breaks the filler down.

Sounds amazing — but are there any risks or safety concerns people should know about before getting lip fillers?

Great question! Like any cosmetic treatment, lip fillers come with potential risks — especially if done by someone inexperienced. The most common side effects are mild swelling, bruising, or tenderness right after treatment, which usually resolve within a few days.
The bigger risks — though rare — happen when filler is injected into or too close to a blood vessel, which can restrict blood flow and cause complications. That’s why it’s absolutely essential to go to a qualified medical injector.Also, avoid “at-home” or “party” fillers — they’re dangerous and illegal in many places. A professional will always use sterile, FDA-approved products and prioritize your safety.

That makes total sense. Let’s talk about the fun part — the look! How do people choose their lip shape or style when getting filler?

Ah yes, the creative side, there’s no one-size-fits-all lip — the goal is to enhance your features, not erase them.
During your consultation, your injector will consider your natural lip shape, facial balance, and aesthetic goals. Some people love the “Russian lip” look — which lifts and defines the Cupid’s bow for that doll-like, vertical height — while others prefer a “classic enhancement,” which adds subtle volume and smooths the lip line.
A good injector will customize your treatment — maybe just a little filler in the border for definition, or more in the center for plush fullness. The best results look effortlessly natural — like you, but just a bit more polished.

Love that — natural is definitely in. Finally, what about the practical stuff — how much does it cost, and what’s recovery like?

At our Medical Dental Spa, lip filler treatments start from £350 for 1ml. The exact amount depends on your individual goals — some clients prefer a subtle enhancement using a smaller amount, while others opt for a fuller transformation. During your consultation, we’ll tailor your treatment plan to achieve balanced, natural results that complement your facial features.

In terms of recovery, it’s all quite manageable. You may experience some mild swelling or tenderness for the first 24–48 hours, and your lips can feel slightly firm or “bouncy” for up to a week. Applying ice packs, staying hydrated, and avoiding alcohol or salty foods can help reduce swelling more quickly.

Most clients see their final results after around two weeks, once any initial swelling has settled. Maintenance treatments are usually recommended every 6 to 12 months, depending on how your body naturally metabolises the filler and your desired look.
