Question 1

What Are Lip Filler Injections or Lip Fillers?

Accepted Answer

Lip filler injections, often referred to simply as lip fillers, are cosmetic procedures designed to enhance the volume, shape, and definition of the lips. These injections typically contain Hyaluronic Acid, a naturally occurring substance in the body known for its hydrating properties. These injections are designed to fill wrinkles, add volume, and define the lips, giving them a fuller and more enhanced appearance. While lip fillers offer a safe and effective way to enhance your lips, it's crucial to choose an experienced and licensed professional for the procedure.

Question 2

How much lip filler do I need?

Accepted Answer

Most patients at Sisu Clinic start with 1ml of lip filler, which is our standard treatment. Your doctor will assess your lip shape, proportions, and what you're hoping to achieve during your consultation, and recommend the right approach for your features. If you're interested in a more subtle enhancement as part of a combined treatment, ask your doctor about our Taylor Package — which includes 0.5ml lip filler, 3 areas of anti-wrinkle, and a free lip flip for a perfectly balanced smile.

Question 3

Do lip fillers ruin your lips?

Accepted Answer

No — when performed by a qualified doctor using medical-grade hyaluronic acid filler, lip injections are safe and will not damage your lips. Lip fillers have been used in aesthetic medicine for decades and have an extensive safety record. At Sisu Clinic, every lip filler treatment is doctor-led, using only CE-marked medical products. Because hyaluronic acid is naturally metabolised by the body over 6 to 12 months, the effects are temporary and fully reversible. The ruined lips concern typically comes from overfilling by unqualified practitioners — which is exactly why choosing a doctor-led clinic matters.

Question 4

What is the difference among a lip lift, a lip flip, and lip filler injection?

Accepted Answer

The main difference among a lip lift, a lip flip, and lip augmentation is that a lip lift involves surgery, and a lip flip uses anti-wrinkle injection to achieve the intended result. A lip lift is typically performed by a surgeon and can be quite invasive and painful. The cost of the procedure is also typically much higher and the results are permanent. A lip flip is a non-surgical treatment that uses anti-wrinkle injection to relax the muscles in your upper lip, “flipping” your top lip upward to make your lip appear fuller. A lip flip does not last as long as lip filler. At Sisu, our lip filler treatment is completely pain-free and non-invasive, and despite it being a temporary treatment, the results are long-lasting.

Question 5

How long do Lip Fillers last?

Accepted Answer

Lip fillers typically last between 6 and 12 months. The lips are a high-movement area — we speak, eat, and express ourselves constantly — which means filler metabolises faster here than in areas like the cheeks. Individual factors like metabolism, lifestyle, and the amount of filler used all affect how long results last. First-time patients often find their results don't last as long as subsequent treatments, as the lips build up a filler memory over time. Most patients book a top-up every 9 to 12 months to maintain their result.

Question 6

What to expect your during Lip Filler Treatment?

Accepted Answer

Your treatment begins with a one-to-one consultation with a Sisu doctor. Your doctor will assess your lip shape, listen to what you're hoping to achieve, and recommend the right approach and amount of filler. A numbing cream is applied before treatment begins to ensure you're comfortable. The filler is then injected precisely using a fine needle, and the lips are gently massaged to ensure even distribution. The procedure takes 15 to 20 minutes. Results are immediately visible, though some swelling in the first 24 to 48 hours is completely normal — your final result settles at around 2 weeks.

Question 7

Are lip fillers permanent?

Accepted Answer

No — lip fillers are temporary. Hyaluronic acid, the substance used in all Sisu lip filler treatments, is naturally broken down and absorbed by the body over time. Results typically last 6 to 12 months before gradually fading. This is one of the key advantages of hyaluronic acid filler over other options — if you ever want to change your result or return to your natural lips, the filler can be fully dissolved using an enzyme called hyaluronidase. You are never locked in.

Question 8

Are lip fillers safe?

Accepted Answer

Yes — lip fillers are safe when performed by a qualified medical professional using medical-grade products. At Sisu Clinic Ireland, every lip filler treatment is carried out by a doctor with aesthetic medicine training. Our doctor-led approach means your treatment is guided by clinical expertise, precise anatomical knowledge, and a thorough consultation process — including full informed consent before treatment begins. We use only CE-marked, medical-grade hyaluronic acid products. The most common side effects — mild swelling and bruising — are temporary and resolve within a few days. Serious complications are rare. We discuss all risks in full at your consultation so you can make an informed decision with complete confidence.

Question 9

How do Lip Filler work?

Accepted Answer

Lip fillers work by injecting hyaluronic acid — a naturally occurring substance found throughout the body — into targeted areas of the lips. Hyaluronic acid attracts and binds water molecules in the surrounding tissue, creating a plumping and hydrating effect. Your doctor places the filler precisely at specific anatomical points: the vermillion border to define the lip line, the cupid's bow for shape, and the body of the lip for volume. The placement varies based on your individual lip shape and the result you're looking for. Because hyaluronic acid integrates naturally with your tissue, the result looks and feels like your own lips — just fuller and more defined.

Question 10

What are the benefits of lip fillers compared to other treatments?

Accepted Answer

The main benefits of hyaluronic acid lip fillers are: immediate results visible on the day, fully reversible using dissolving enzyme, natural-looking when performed by an experienced doctor, no surgery or downtime required, and long-lasting results of 6 to 12 months. Compared to a lip flip (anti-wrinkle injection), fillers add actual volume rather than just the appearance of fullness — making them more suitable for patients who want a meaningful enhancement. Compared to surgical lip lifts, fillers are non-invasive, temporary, and significantly more affordable. For most patients looking for fuller, more defined lips, hyaluronic acid lip filler is the safest, most predictable, and most reversible option available.

Question 11

What are lip fillers and how do they work?

Accepted Answer

Lip fillers are injectable treatments that use hyaluronic acid — a naturally occurring substance in the body — to add volume, improve shape, and define the lips. When injected precisely into targeted areas of the lips, the filler attracts moisture and creates a subtle plumping effect. At Sisu Clinic, all lip filler treatments are performed by doctors using medical-grade hyaluronic acid products. Results are immediate, fully reversible, and last between 6 and 12 months.

Question 12

How much do lip fillers cost in Ireland?

Accepted Answer

Lip fillers at Sisu Clinic Ireland are priced at €300 for 1ml, with a free consultation included. For patients looking for a more subtle lip enhancement as part of a broader treatment, our Taylor Package combines 0.5ml lip filler with 3 areas of anti-wrinkle and a free lip flip — ask your doctor about this during your consultation. All pricing is transparent with no hidden costs.

Question 14

How long does lip filler swelling last?

Accepted Answer

Some swelling after lip filler is completely normal and expected. Swelling is typically most noticeable in the first 24 to 48 hours after treatment, then gradually subsides. Most patients look presentable within 3 to 5 days. The final, fully settled result is visible at around 2 weeks. Initial swelling can make the result look more dramatic than it will be once settled — so it's important not to judge the outcome in the first few days. Applying a cold compress gently (never directly on the lips) in the hours after treatment can help reduce swelling.

Question 15

What is the difference between lip filler, a lip flip, and a lip lift?

Accepted Answer

Lip filler uses hyaluronic acid injections to add actual volume to the lips — it's the most popular option for patients wanting a fuller, more defined pout. A lip flip uses a small amount of anti-wrinkle injection above the upper lip to relax the muscle and cause the lip to subtly roll outward, creating the appearance of fullness without adding volume. It's a good option for subtle enhancement or for patients not ready for filler. A lip lift is a surgical procedure that permanently shortens the distance between the nose and upper lip — it's more invasive, more expensive, and irreversible. At Sisu Clinic we offer both lip filler and lip flip treatments, and many patients combine both for a more complete result.

Question 16

Can I get lip fillers for the first time at Sisu Clinic?

Accepted Answer

Yes — many of our patients are first-time lip filler patients, and we are very experienced at guiding people through their first treatment. Your doctor will take extra time during the consultation to explain exactly what will happen, answer all your questions, and make sure you feel completely confident before proceeding. We always recommend a conservative approach for first-time patients — starting with 0.5ml or 1ml and assessing the result before deciding on more. There is never any pressure to proceed after your consultation.
