Do you want fuller or better-shaped lips, but are unsure which filler suits you best? There are different types of lip fillers, and the choice helps determine how natural and how long your result feels. On this page, you'll read about the types of lip fillers, how they differ, and how Dr T. chooses the right one together with you. Subtle and respectful, tailored to your lips and what you want to achieve.

Most lip fillers are based on hyaluronic acid, a substance your body also produces and which retains moisture in the skin. That makes them safe, predictable, and, importantly for your lips, biodegradable. For the lips, hyaluronic acid is almost always chosen, not permanent or biostimulating fillers, because your lips move a lot and a soft, natural result is essential here.
Within these hyaluronic acid fillers, there are different variants. They mainly differ in thickness (how firm or flexible the gel is), in how much volume they provide, and in how they feel after treatment. A flexible, light filler tends to give hydration and fine definition, while a firmer product can build more volume and structure.
So there is no single best lip filler. The best choice is the filler that suits your lip shape, your skin, and the effect you have in mind. That's why Dr T. first looks at your lips before a product is chosen.
Flexible, thin-flow fillers spread easily in the tissue. They are ideal if your lips mainly need some hydration, gloss, and a soft definition, or if you are considering a lip filler for the first time and want to start very naturally. The result feels light and is barely noticeable as a treatment.
Firmer fillers hold their shape better and can provide more projection or a clearer contour, for example to accentuate a beautiful bow (the Cupid's bow) or to build volume in thinner lips. They do require precise placement, because too much firmness in the wrong place can feel unnatural.
In practice, it's rarely about just volume. Often it's about the right balance between shape, definition, and a natural movement when you talk or laugh. Which filler is most suitable for that depends on your lips and wishes.
Do you have naturally thin lips and want more volume? Then a somewhat firmer filler might be suitable. Do you want to mainly refine, hydrate, or subtly correct a slight asymmetry? Then a more flexible product is often the better choice. Your age, skin quality, and existing lip shape also play a role in the choice.
Sometimes a lip filler is not the right solution, and we say that honestly. With an active cold sore (herpes), an inflammation or infection around the lips, or with certain conditions and medications, we better wait or look for another moment or a different approach. During pregnancy or breastfeeding, we never treat. If you have very high expectations that don't match your face, we discuss that openly instead of treating anyway.
The goal is always a result that fits your face, not a trend. If a lip filler doesn't match what you're looking for, Dr T. honestly discusses which alternative is useful.
Everything starts with a consultation. In it, Dr T. looks at your lip shape, the ratio of upper to lower lip, your skin, and the way your lips move. You tell what bothers you or what you would like to see differently, and together you determine a realistic goal.
Based on that, Dr T. chooses the type of filler and the amount. Often it's preferred to build up gradually rather than placing a lot of volume at once: that way the result stays natural and you can always adjust. The treatment itself is done with fine needles or a microcannula, usually with a numbing component in the filler or a local anesthetic for more comfort.
Because most lip fillers are biodegradable, there is also a safety margin: in rare cases, hyaluronic acid can be dissolved. That gives peace of mind when making a choice. During your consultation, you'll get full explanation about this.
Shortly after the treatment, your lips may feel somewhat swollen and they are sometimes slightly bruised or sensitive. That's normal and usually disappears within a few days. The real, final result is best assessed not immediately, but only after the swelling has completely gone.
How long a lip filler lasts varies per person and per type of product. Lips move a lot, so filler here is generally broken down faster than in other places on the face. The flexibility of the filler, your metabolism, and lifestyle all play a role, so we don't promise exact durations.
What you can expect is a gradual, natural decrease rather than a sudden disappearance. If you want to maintain your result, a refreshment treatment at the right time can help. What is realistic for you, Dr T. discusses during the consultation.
Lip fillers with hyaluronic acid are well studied and are considered safe when placed by experienced hands. Yet it is a medical treatment with possible side effects. Temporary swelling, bruising, sensitivity, or small irregularities that disappear on their own are most common.
Rarer risks exist, such as lumps, an inflammation, or, very exceptionally, a vascular problem if filler ends up in or near a blood vessel. That's why anatomical knowledge and careful work are so important. Dr T. explains these risks honestly, so that you make an informed choice and know what to watch for after the treatment.
Are you unsure whether a lip filler suits you, or do you have questions about the types and what is safe for your situation? Feel free to plan a consultation. Then we'll calmly look together at what suits you best.

Every set of lips is unique, so each deserves a tailored filler. Whether you're after a subtle moisture boost, better definition, or enhanced symmetry, the right product and injection method make the difference between an artificial look and radiant, natural beauty.
HA fillers differ not only in thickness but also in cross-linking, the molecular bonds that determine longevity and lift. Highly cross-linked gels persist longer and offer more support, while lightly cross-linked ones stay soft and blend seamlessly with lip tissue. At our Ghent clinic, we select products that strike an ideal balance between structure and suppleness, adapted to your skin type and age.
Beautiful lips aren't created with a single syringe; they're built in delicate layers. By injecting precisely along the lip border and into the central volume, Dr T. sculpts a three-dimensional result that moves naturally with your expressions. This technique avoids the rigid, overfilled look many people worry about. Adding a whisper of filler to the Cupid's bow or philtrum can also produce a barely-there yet stunning refinement.
Each lip treatment starts with a thorough assessment: the distance from nose to lip, upper-to-lower-lip proportions, skin elasticity, and the volume of surrounding features. Based on these insights, a personalised plan emerges. For very thin lip skin, Dr T. might first use a light, hydrating filler to condition the tissue before adding structural volume. The result: subtle rejuvenation that no one can identify, but everyone notices.
