Lip filler: everything you need to know for natural and well-defined lips

KEIT Day Hospital has clinical facilities dedicated to aesthetic medicine treatments, organised to ensure appropriate standards of hygiene, procedural precision and patient comfort.
For lip filler treatment, the doctor assesses the shape of the upper and lower lips, the definition of the Cupid's bow, the vermilion border and lip symmetry, using instruments and materials specifically designed for injectable procedures. Treatment is performed using fine needles or sterile, single-use microcannulas, selected according to the patient's anatomical characteristics and the injection technique.
The organisation of the clinical facilities and the availability of medical resources allow the different stages of the procedure to be managed, from preparation of the skin and lip mucosa to observation immediately after treatment.

KEIT Day Hospital works with medical professionals experienced in aesthetic medicine, injection techniques and facial anatomy. For lip filler treatment, knowledge of the anatomical structures of the lip region is essential for identifying the injection planes, considering the course of the labial arteries and determining the quantity and distribution of the product.
Treatment is personalised according to lip shape, the proportions between the upper and lower lips and the aesthetic goal, avoiding excessive volume increases and prioritising harmonious results.
An additional advantage is the presence of a multidisciplinary medical team within KEIT Day Hospital, allowing specialists in anaesthesia and intensive care or other medical disciplines to be involved when additional assessments or specific medical assistance are required.

Before lip filler treatment, the doctor carries out an individual assessment of lip shape, volume, symmetry and proportions, also considering the patient's expectations. The consultation includes taking a medical history, with particular attention to allergies, medications being taken, previous aesthetic treatments, active infections, episodes of cold sores and possible contraindications.
Assessment of the lips makes it possible to distinguish naturally thin lips from age-related volume loss, identifying any asymmetries or changes in lip contour. Treatment is not planned according to standard filler quantities but according to anatomical characteristics and the degree of correction actually required.
When the aim is only to improve the definition of the vermilion border or Cupid's bow, the doctor may plan targeted injections without necessarily increasing overall lip volume significantly.

KEIT Day Hospital follows hygiene and infection prevention protocols that include disinfecting clinical areas, skin antisepsis and the use of sterile, single-use devices during injectable treatments. For lip filler treatment, particular attention is paid to proper preparation of the perioral area, the handling of needles and microcannulas and checking the packaging of the products used.
Each filler is identified by its brand name, batch number and traceability information, which are recorded in the patient's clinical documentation. The choice of hyaluronic acid takes into account the product's characteristics, the mobility of lip tissues, the injection technique and the desired result. These checks contribute to treatment safety and traceability.

Lip filler treatment is a minimally invasive procedure, generally performed without general anaesthesia. To improve patient comfort, products containing lidocaine or other local anaesthetic measures may be used when indicated. Non-surgical aesthetic treatments also require medical expertise and appropriate preparation for managing complications.
In addition to temporary effects such as swelling, tenderness or bruising, asymmetries, nodules, infections or rare but serious complications, including vascular occlusion, may occur. Prompt recognition of symptoms and activation of emergency protocols are essential.
Managing suspected vascular occlusion caused by hyaluronic acid requires specific protocols, which may include the prompt use of hyaluronidase when indicated. Any visual disturbances require immediate emergency specialist care.
One of KEIT Day Hospital's distinguishing features is the availability of hospital infrastructure and a multidisciplinary medical team. The facility has three equipped operating theatres, specialists in anaesthesia and intensive care, equipment for monitoring vital signs, emergency management devices and a postoperative recovery room. These resources provide additional medical support, alongside the specific protocols required to manage complications associated with injectable treatments.

At KEIT Day Hospital, patient care continues after lip filler treatment has been completed. Patients receive personalised instructions on precautions to take, temporary effects that may occur and warning signs requiring immediate medical assessment.
Follow-up is determined according to the patient's individual response to treatment. A follow-up appointment after approximately 10–14 days, when indicated, allows the result to be assessed after the initial swelling has subsided, checking symmetry, contour definition, volume distribution and the possible presence of irregularities.
For international patients, care may also continue remotely through communication with medical staff and guidance on necessary follow-up appointments. KEIT Day Hospital also provides an emergency contact number, available 24 hours a day, 7 days a week.

KEIT Day Hospital places particular emphasis on transparent information and treatment documentation. Before lip filler treatment, patients receive explanations about the selected product, the areas to be treated, expected benefits, the approximate duration of the results and potential risks.
Clinical documentation records the filler's brand name, batch number, quantity administered and injection sites, ensuring traceability of the procedure. When appropriate and with the patient's consent, photographic documentation is taken to compare the initial appearance with the treatment result. The informed consent form, treatment quotation and administrative documentation also allow patients to understand the clinical and financial aspects of the procedure before undergoing treatment.
