At Princesse we are aware of how many people struggle with complications after aesthetic medicine procedures. That is why we have created a separate unit to treat complications.

Our clinic has already helped several hundred Patients with complications, mainly after filler administration. What causes such a huge number of complications? After all, aesthetic medicine is considered safe, and all preparations administered are tested medical devices.

The problem is that in light of the current legal regulations literally anyone can perform aesthetic medicine procedures. Patients often undergo procedures in the surgeries of people who do not have any specialist education, but have only completed a one-day course. Of course, a complication may also occur after a procedure performed by the most experienced specialist. The difference, however, is that a physician can usually quickly recognise a developing complication and can provide emergency assistance. A non-medically qualified individual is usually not trained to recognise an emergency, and even if they are able to do it, they cannot administer medication or apply the necessary therapy. They hastily begin to search for a physician who can help their customer. Not every aesthetic physician specialises in treating complications or has experience in managing emergency situations, especially after a procedure performed by someone else, because they do not know how or what exactly has been administered. We have frequently heard of situations where an experienced physician has refused to treat complications after a aesthetic medicine procedure performed in a cosmetic surgery. When the Patient needs urgent help, is there time to argue about who should practice aesthetic medicine and who is not qualified to do so? No, let’s leave this to the legislators! It is against the Code of Medical Ethics to refuse to help in case of a medical emergency, but, according to our Patients, it happens very often. Alarmed by the situation on the market and seeing how great is the demand for professional services in the field of treating complications, we have created the Centre of Complication Treatment.



Aesthetic medicine is aimed at making us look better. However, the procedure may not bring a desired results, especially when it is performed by an inexperienced person with poor professional knowledge. It often results in deformities, frequently leading to low mood, lack of acceptance of one’s appearance and even depression. Fortunately, most of the effects can be reversed or hidden with a corrective procedure.
Undoubtedly, the most common failure is improperly augmented lips, which instead of looking flat and natural are inflated in a very unsightly way, have an undulating smile line and are full of nodules and asymmetries.
The second procedure that, when performed incorrectly, causes frequent complications is tear through filling with hyaluronic acid fillers. The filler placed too close to the surface causes lymphatic stasis and the Tyndall effect, i.e. hyaluronic acid shining through and unsightly lump formation.
There are several possibilities of treatment after improper injection of hyaluronic acid – from squeezing the filler out to dissolving it with hyaluronidase or a corrective procedure. Your physician will suggest the best solution during the appointment.

However, no aesthetic complication is as dangerous as medical complications, described further on.


The most dangerous complication after hyaluronic acid administration is blockage of a blood vessel. This can happen in two ways. The first way is injecting the filler directly into the vessel lumen. The other way is blockage of the vessel through strong pressure of the filler on the tissues. Both are equally dangerous, because if left untreated, they lead to tissue necrosis. The first symptoms of vessel blockage after hyaluronic acid injection include severe pain, whitening and cooling of the skin in the site of injection, tingling and numbness, and even loss of sensation. When working around the eye or nasolabial folds, sudden loss of vision can also be a symptom. In 90% of cases, symptoms appear immediately after administration and an experienced physician can recognise them and apply the appropriate treatment. However, in 10% of cases, symptoms may not appear until two to three days later, when the Patient is already at home and the acid has increased in volume by taking on water and can cause vascular compression. Therefore, if you notice any of the worrying symptoms after a hyaluronic acid procedure, immediately contact the physician who has performed the procedure or visit us – we are very experienced in treating even the most serious complications.
When a vessel becomes blocked, surrounding tissues do not receive enough blood and the process of their degeneration begins. To prevent irreversible changes, hyaluronic acid must usually be dissolved within a few hours. After rapid intervention, everything usually returns to normal immediately; circulation in the tissues is restored. However, Patients often report too late, sometimes even a few days after noticing symptoms. In some cases, they have tried to get help from the person who performed the procedure, but this person has not been able to help them due to not having necessary qualifications, experience or knowledge.
When the condition is already advanced, and severe bruising or petechiae can be seen on the skin, and it has even begun to decompose, in addition to dissolving the hyaluronic acid, we use long-term antibiotic therapy and medication to help restore circulation. Unfortunately, if a long time has passed since the vessel became blocked, the effects are not always reversible and tissue transplant is necessary. This is why it is so important to seek help as soon as possible in case of a suspected hyaluronic acid vessel blockage.
Which procedures entail the greatest risk of this complication? Undoubtedly, a forehead is the most dangerous area. Complications after hyaluronic acid administration in this area are so frequent that aesthetic medicine cosmetic medicine clinics have completely abandoned injecting fillers in this area. The second most dangerous area is a nose. Procedures around it should be performed very carefully with small amounts of hyaluronic acid per session. All other areas also require attention and safe administration.


Various types of complications can happen after plastic surgery. Usually, another surgical intervention is necessary. A large proportion of complications include cartilage or bone irregularities and collapses after rhinoplasty. They are difficult to reverse, much more costly than the initial surgery, and is a much more difficult procedure.

A procedure that has gained popularity and very often gives complications is a cortisone crystal nasal injection. Even the Polish Society of Plastic, Reconstructive and Aesthetic Surgery has issued a warning against this procedure:

“In recent years, we have heard information on the use of crystalline cortisone for nonsurgical nasal correction. Percutaneous administration near the tip of the nose is aimed at its narrowing, slimming and lifting. Taking into account both theoretical and practical knowledge, this procedure should be considered dangerous and incompatible with the art of medicine. Its imprudent use in the nasal region for aesthetic indications raises justified concerns about distant consequences in the form of nasal cartilage, subcutaneous tissue and skin atrophy. As a consequence, it may result in irreversible deformation of the nasal shape.”

In case of both a failed rhinoplasty and after a crystalline cortisone procedure, deficiencies may be compensated with minimally-invasive administration of hyaluronic acid. At Princesse we have extensive experience in this type of corrective procedures.


Nerves run shallowly beneath the skin. Improperly performed injection can easily irritate them, leading to chronic pain. This can also happen after injecting the filler in the wrong place – then the filler presses on the nerve, causing various types of neuropathy. There are also more and more frequent cases of nerve paralysis after incorrect thread lifting. In case of nerve palsy, it is necessary not only to remove the cause but also to apply pharmacotherapy.

Another type of nerve palsies is caused by complications after botulinum toxin administration. These manifest themselves as drooping eyelids, drooping mouth corners or even breathing problems. There is no effective antidote for botox injections, the only solution is waiting for about 3-6 months and applying conservative treatment or performing a corrective procedure to help hide the defect.


Thread lifting is a safe procedure, however, like any procedure that interrupts skin continuity, they can cause complications. The most common cases of complications after thread lifting include too shallow insertion of a thread, which makes it palpable or even visible, and an incorrectly cut thread, making its tip stick out of the skin, which is an open way for bacteria and leads to infection. Incorrectly placed threads usually have to be removed and in case of infection, antibiotic therapy is implemented.


A keloid is an oversized scar that requires treatment. It can also form on badly sutured wounds or after an infection. This is a very unfortunate situation when it appears after plastic surgery, which was supposed to improve appearance and not disfigure it with an unattractive scar.
At Princesse we use combined strategy for keloid treatment, designing it precisely according to the Patient’s needs. We have a whole arsenal of measures at our disposal: fraxel laser, platelet rich plasma, steroid drugs administered through topical injection, as well as supporting repair procedures.
Another type of scars are those caused by burns as a result of unprofessional laser procedure. Their treatment is long and difficult, but possible.


Non-resorbable fillers, such as Aquamid, Bio-Alcamid or liquid silicone, were commonly used 10-20 years ago. Their negative effects were not known then. Today, many Patients struggle with their late side effects, such as displacement, granulomas, tissue necrosis, bacterial biofilm and even severe inflammation, which can be life-threatening. Therapy for these side effects can be very difficult and lengthy, but the Patient needs to realise that the longer they delay it, the more difficult the situation becomes. At Princesse we apply both surgical and pharmacological procedures.


Hyaluronic acid is virtually non-allergenic; however, substances used for its crosslinking, such as BDDE or PEG, may cause allergies. Apart from that, practically any substance used in aesthetic medicine, from botulinum toxin to vitamin preparation used for mesotherapy, may be allergic. Symptoms of allergy include itching, redness and swelling in the application site, and in more serious cases swelling of the tongue and throat and breathing problems. Never delay in getting help, one dose of medication is usually enough to cure postoperative allergies.
And what is a perioperative infection? It occurs after an unsterile procedure or after unhygienic care for the treatment site by the Patient. Is symptoms include redness, swelling and pain at the injection site, as well as by pus oozing from the injection wounds. Another possible symptom is high temperature. An untreated infection after a aesthetic medicine procedure can spread and even lead to sepsis. Treatment usually takes the form of appropriately selected antibiotic therapy.
