Lip filler is a hyaluronic acid treatment used to add volume, define the border, balance asymmetries and improve hydration in the lips.
The lips are the focal point of the face and the most frequently overdone area. With age lips thin, roll inward and lose hydration. My aim is not to enlarge the lip but to restore fullness within its own shape, in proportion with the rest of the face. I describe what filler does in other areas of the face on the dermal fillers page.
What a natural lip shape means
Every lip is different, but certain proportions are widely accepted in aesthetic assessment. In the proportion generally considered ideal, the lower lip is slightly fuller than the upper lip. A defined “M” curve in the upper lip, the Cupid’s bow, is also regarded as a marker of youth.
I use these proportions as a starting point rather than a template. Your face shape, jaw structure and the distance between nose and lip all modify them.
The decision between lip and nasolabial comes down to where the shadow originates: if the fold running from the side of the nose to the corner of the mouth is in the foreground, nasolabial filler; if the volume and border of the lip itself are in the foreground, lip filler comes forward. One does not replace the other; the final choice is made at the consultation.
How I avoid the projected look
The concern I hear most is the lip that projects forward. This comes from placing product in the wrong plane and beyond the natural border of the lip.
I place product within the anatomical border — the vermilion — between the mucosa and the muscle. This allows the lip to become fuller within itself without altering its profile. Depending on the area I may use both a fine needle and a blunt-tip cannula: the cannula adds volume while reducing bruising, the fine needle defines the border and the Cupid’s bow.
I avoid techniques that flatten the lip and require a large number of entry points. I prefer an approach that preserves the three-dimensional curve of the lip.
How the treatment works
- Assessment. Facial proportions, the lip border and existing asymmetries are evaluated.
- Product selection. The lip is in constant motion, so soft, flexible products that move with the tissue are preferred.
- Application. The treatment takes about 20 minutes.
The lips are the area patients are most anxious about beforehand. For those who are particularly apprehensive I can use a regional block — an option that comes from my anaesthesiology practice and one that works well here.
The lips are among the most mobile and best-perfused areas of the face, so product breaks down faster here than elsewhere. Average longevity is 6 to 12 months.
At a first treatment I do not deliver the entire intended result in one session. My preference is to start with part of what we have planned and complete it at a review once the swelling has settled. In the lips, too much is far harder to correct than too little, whereas adding what is missing later is straightforward.
If you are visiting Istanbul and have only one appointment, I will tell you at consultation and plan accordingly — a single, conservative session rather than a full correction. That is a deliberate choice rather than a compromise.
Safety and anatomy
The main consideration in filler treatment is placing the product in the correct plane relative to the tissue and the vascular anatomy. For that reason I prefer a blunt-tip cannula in suitable areas, working in the deep plane and advancing slowly. In a large published cohort study, the rate of vascular events in experienced hands was reported as roughly one in 6,400 syringes with a needle and one in 40,000 with a cannula — infrequent with either technique, and less frequent still with a cannula 2. Experience also matters: in the same study, rates were markedly lower among physicians with more than five years of practice. The fact that hyaluronic acid based products can be dissolved if needed provides an additional margin of safety; I explain this on the filler dissolving page.
Aftercare
A few simple points on the first day are enough to keep the result where we planned it:
- Do not apply make-up or cosmetic products to the treated area for the first 24 hours.
- Do not massage or rub the treated area.
- Avoid very hot showers for the first 24 hours, and saunas and steam rooms for the first week.
- Avoid heavy exercise and intense cardio for the first week.
- Avoid alcohol on the day of treatment, and do not smoke for the first 4 hours.
- Drink plenty of water; hyaluronic acid binds water in the tissue, which helps the result settle.
- Avoid kissing and pressure on the lips for the first 24 hours.
- Avoid very hot or very cold food until the numbness wears off.
Short-lived mild redness, tenderness or a small bruise may appear at the injection points; these resolve on their own within a few days. Because an allergic reaction can occur rarely, treatments are carried out under medical supervision.
What we review together at your consultation
- Pregnancy and breastfeeding
- Active skin infection or an unhealed wound in the treatment area
- Known hypersensitivity to filler components
- The active phase of an autoimmune condition, if you have one
- Permanent filler previously placed in the same area
- Your current medication and general health
- Recent or planned dental treatment
- History of frequent cold sores
If one of these applies to you, we plan a more suitable alternative rather than the treatment.
Planning your visit
The clinic is in Nişantaşı, Şişli, Istanbul, about 45 minutes from Istanbul Airport. A stay of 2–3 days covers arrival, consultation and treatment, and departure. Injectable fillers need no recovery period; mild swelling may last two to three days, so if you have an event we plan the appointment around it. I do not commit to a plan over messages: we speak before you travel so you know what is realistic, and we confirm it in person on the day. Flying is usually fine 24 hours after an injectable treatment. Remote follow-up and contact are provided, and consultations are held in English.
Pricing
Under the applicable regulations, price information cannot be published on our website. The cost of a treatment depends on the product used, the technique chosen and the extent of the treatment. You can call the clinic for detailed information.
Frequently asked questions
Will my lips feel lumpy?
Firmness related to swelling can be felt for the first few days; this softens quickly as the product integrates with the tissue. The risk of a lasting irregularity is low with correct placement and quantity. If one does remain, hyaluronic acid products can be dissolved — see filler dissolving.
Can I kiss and eat normally afterwards?
Avoiding pressure on the lips and kissing for the first 24 hours helps the product settle. You can eat normally, but avoid very hot or very cold food until the numbness wears off.
I have had lip filler and I don’t like it. What can be done?
If a hyaluronic acid product was used it can be dissolved. I would ask you to wait until the result has settled first — the appearance in the first two to three weeks is not the result, and most patients are satisfied once they have waited.
