Lip filler typically lasts between 6 to 12 months, though this varies depending on several factors. The type of filler used, the amount injected, your metabolism, lifestyle habits and how expressive your lips are all play a role. Some people notice their filler breaking down more quickly if they exercise frequently, have a fast metabolism or are very animated when speaking. Most practitioners recommend booking a review appointment around 6 months after your initial treatment to assess whether you need a top-up. With regular maintenance sessions, some people find their results last slightly longer over time as the lips adapt to the filler.

Most people experience some discomfort during lip filler injections, but the level of pain varies from person to person. The lips are a sensitive area with many nerve endings, so you may feel stinging, pressure or pinching during the procedure. However, most practitioners use fillers that contain local anaesthetic (lidocaine) and may also apply numbing cream beforehand to minimise discomfort. Many people describe the sensation as tolerable rather than painful. After treatment, your lips may feel tender, swollen or bruised for a few days, but this usually settles quickly. If you are particularly anxious about pain, discuss your concerns with your practitioner beforehand so they can take extra steps to keep you comfortable.

Fillers for lips are injectable treatments used to enhance the size, shape and definition of the lips. They are most commonly made from hyaluronic acid, a substance naturally found in the body that attracts and holds moisture. Lip fillers can add volume to thin lips, improve symmetry, define the lip border, smooth out fine lines around the mouth or create a fuller, more balanced appearance. The treatment is temporary and gradually breaks down over time, giving you flexibility to adjust or maintain your look. A skilled practitioner will tailor the type and amount of filler to suit your facial proportions and aesthetic goals, aiming for natural-looking results that enhance rather than dramatically change your features.

Lip filler swelling is very common and usually peaks within the first 24 to 48 hours after treatment. Most people find that the majority of swelling subsides within 3 to 5 days, although some mild puffiness or unevenness can linger for up to two weeks. The extent and duration of swelling varies depending on individual factors such as the amount of filler used, your natural healing response and whether you experience bruising. To manage swelling, your practitioner may recommend applying ice packs, keeping your head elevated, staying well hydrated and avoiding strenuous exercise, alcohol and heat for the first few days. It is important to wait until all swelling has settled before judging your final result, as lips can look larger or uneven initially.

It is strongly advised not to have lip filler or any cosmetic injectable treatments during pregnancy or while breastfeeding. Although hyaluronic acid fillers are generally considered safe in non-pregnant individuals, there is limited research on their effects during pregnancy and lactation. Most medical professionals and aesthetic practitioners follow a precautionary approach and recommend postponing any elective cosmetic procedures until after you have finished breastfeeding. Your health and your baby's wellbeing should always be the priority, so it is best to wait until it is safe to proceed. If you are unsure or have questions, speak to your GP or midwife before considering any aesthetic treatment.

After lip filler treatment, there are several important things to avoid to ensure optimal healing and results. For the first 24 to 48 hours, avoid strenuous exercise, alcohol, excessive heat (such as saunas, steam rooms or very hot showers), and blood-thinning medications unless prescribed by your doctor, as these can increase swelling and bruising. You should also avoid massaging or pressing on your lips unless specifically instructed by your practitioner, as this could move the filler or cause unevenness. Kissing, wearing lipstick or applying pressure to the lips should be minimised for the first day or two. Avoid dental work, facials or other facial treatments for at least two weeks. Sun exposure and flying can sometimes worsen swelling, so take care if you have travel plans. Always follow your practitioner's specific aftercare instructions, as they may tailor advice based on your treatment and individual needs.

Before lip filler, people often have concerns such as thin or asymmetrical lips, lack of definition, a flat or undefined lip border, or fine lines around the mouth. After a well-executed lip filler treatment, the lips typically appear fuller, more balanced and better defined, with improved hydration and a smoother texture. The degree of change depends on the amount of filler used, the technique and your natural lip anatomy. Most people aim for a natural enhancement that complements their facial features rather than an overdone or artificial look. Immediately after treatment, lips may appear swollen or uneven, so it is important to wait at least two weeks for swelling to settle before assessing the final result. Your practitioner can show you examples of their work and discuss realistic expectations based on your starting point and desired outcome.
