As a specialist, he places great importance on personalized consultation and customized treatment concepts to meet the individual needs of his patients. At his private practice "New Aesthetic Vision" in Cologne, he offers a wide range of aesthetic treatments that combine the highest medical expertise with the most advanced methods. He is among the leading experts in aesthetic facial surgery in Germany.
The distinguished professor combines the latest medical knowledge with excellent surgical expertise. His name stands not only for highly specialized eyelid surgery and the treatment of disorders of the tear ducts, ocular surface, and orbit, but also for innovative minimally invasive procedures – such as scar-free operations using laser technology. Prof. Dr. Dr. Heindl is nationally and internationally recognized, both for his scientific publications and for his significant contributions to advancements in ophthalmic reconstructive surgery.
Alongside his high level of expertise in ophthalmic oncology (eye tumors), he is also distinguished by a comprehensive, interdisciplinary therapeutic approach. Every patient benefits from individually tailored treatment strategies developed in close collaboration with other specialties. With his passion for ophthalmology, his scientific dedication, and his high standards for holistic patient care, Prof. Dr. Dr. Heindl always places the patient and their individual needs at the center of his work.
Furthermore, Prof. Dr. Dr. Heindl demonstrates that modern aesthetic procedures go far beyond mere cosmetic corrections: under his medical expertise, Botox and fillers are not only used for wrinkle treatments but also effectively help with migraines, neurological disorders, excessive sweating, or teeth grinding.
The editorial team of the Leading Medicine Guide learned more about this in an interview with Prof. Dr. Dr. Heindl.
Botox and fillers are often regarded as purely cosmetic procedures for smoothing wrinkles and contouring the face. However, the modern range of applications extends far beyond this: Botox is now successfully used to treat migraines, excessive sweating, and teeth grinding. Fillers not only provide aesthetic improvements but can also alleviate functional conditions. The medical benefits of these substances show how versatile today’s treatment options are – and that aesthetics and health are often more closely linked than one might assume.
The main component of Botox, botulinum toxin type A, blocks the release of acetylcholine, a neurotransmitter responsible for muscle contraction. This property makes Botox a valuable tool in the treatment of a wide variety of medical indications that extend far beyond cosmetic applications.
“When people think of Botox, many first associate it with aesthetic applications – for example, to smooth forehead wrinkles. But botulinum toxin type A, the correct name of the active substance, is much more than just an anti-wrinkle agent. It is one of the best-researched drugs in neurology and has a long medical history that extends far beyond aesthetic medicine. Its earliest uses were in the treatment of neurological movement disorders.
As early as the 1980s, Botox was specifically used – for instance, against strabismus (crossed eyes) or eyelid spasms, known as blepharospasm. Particularly in ophthalmology and neurology, the substance has since become firmly established. Today, Botox is officially approved for numerous medical indications and is also successfully applied in so-called off-label therapies. These include, among others, the treatment of chronic migraines, especially in patients experiencing more than 15 headache days per month. Further areas of application include cervical dystonia, which leads to involuntary head and neck movements, facial muscle spasms such as hemifacial spasm, and again blepharospasm.
Another very relevant field of application is the treatment of spasticity – for example, after a stroke or in the context of multiple sclerosis. Botox is also used against teeth grinding, known as bruxism, when the chewing muscles are overactive. It is equally effective in cases of excessive sweating, or hyperhidrosis, such as under the arms or on the palms. Botox can also provide pain relief, for instance in muscle tension or chronic pain syndromes. All these applications clearly show: medically speaking, Botox is a true multitasker – far more than just a remedy for frown lines”, explains Prof. Dr. Dr. Heindl at the beginning of our interview.
In medical applications, Botox is increasingly used for neurological indications such as migraines and bruxism, since it has the ability to regulate communication between nerves and muscles.
In migraines, a neurological disorder characterized by recurring, often very painful headaches, Botox can reduce both the frequency and intensity of attacks. Migraines are often associated with the overactivity of certain nerves in the brain, leading to increased pain transmission.
“Botulinum toxin specifically blocks the release of the neurotransmitter acetylcholine at the so-called motor endplate. This means that the nerve can no longer transmit an impulse to the muscle – so the muscle either does not contract at all or only contracts weakly. This muscle-relaxing effect is used in the treatment of classic movement disorders. In migraines, however, the mechanism of action is somewhat more complex. Here, Botox not only inhibits muscle activity but also the release of certain neurochemical messengers – such as CGRP, substance P, and glutamate.
These substances play a central role in pain processing and inflammatory processes in the trigeminal nerve. By injecting into specific areas – such as the forehead, temples, back of the head, and neck – the hypersensitivity of the nervous system can be significantly reduced. Studies confirm that the frequency of migraine attacks decreases noticeably”, explains Prof. Dr. Dr. Heindl, before going on to describe its effect on bruxism: “Here, the treatment targets an overactive chewing muscle, particularly the masseter muscle. By injecting Botox, bite pressure is deliberately reduced – this relieves jaw joint pain, prevents dental damage, and stops the chewing muscles from continuing to overdevelop. However, precise dosing is essential to ensure that important functions such as chewing and speaking are not impaired”.
A side effect that many patients welcome: when the forehead is also treated during migraine therapy, forehead wrinkles may be smoothed at the same time. In such cases, medical benefits can be combined with aesthetic effects – though this is not the primary goal. Patients who want to preserve their facial expressions can control this through careful placement and dosage.
There are differences in dosage and technique when Botox is used for medical purposes compared to aesthetic purposes. While both applications involve the same drug, various considerations must be taken into account in medical use.
In aesthetic treatments, such as smoothing wrinkles or treating frown lines, Botox is usually injected in smaller doses into specific, superficial muscles to achieve the desired cosmetic effect. The dosages are generally lower, with the focus on targeted muscle relaxation without significantly restricting natural expression or movement. In medical treatments, however – for conditions such as migraines, bruxism, or excessive sweating – higher doses are required, and injections are often administered into larger areas of the body depending on the specific indication.
“In medical contexts, significantly higher dosages are usually required. Standardized treatment protocols serve as the guideline. For example, in chronic migraine: about 155 units of botulinum toxin are injected at 31 precisely defined points – an established treatment scheme. In neurological disorders such as spasticity or dystonia, the necessary dose can even amount to several hundred units. The exact quantity then depends on the size of the affected muscle group and the individual findings.
The injection technique also differs. While aesthetic medicine tends to use more superficial methods, such as intradermal or superficial intramuscular injections, medical treatments often require injections deep into the muscle. This demands in-depth knowledge of neuromuscular anatomy – in some cases, imaging techniques such as ultrasound or electromyography are also used to precisely target the injection site. The primary goal in medical therapy is not visual smoothing or symmetry, but functional improvement – in other words, the targeted reduction of pathological muscle activity with minimal side effects. A common misconception: the 30 to 33 injection points in migraine treatment do not mean 30 separate appointments – the entire treatment is completed in a single session.
Even though this involves many injections, the treatment is generally well tolerated. The injections themselves cause only a slight pricking sensation. In deeper muscle layers, the puncture is felt somewhat more, but especially for migraine patients, this discomfort is minimal compared to their usual pain. However, the effect does not appear immediately. It takes about two to four weeks for the effect to build up – the so-called ‘peak’ of the treatment. After that, it gradually diminishes. Therefore, it is important for patients not to wait until they are back in full pain, but to schedule follow-up treatments in time. The interval between two sessions is typically three to six months – depending on the individual course”, says Prof. Dr. Dr. Heindl.
Coverage by health insurance providers is a complex issue. For certain indications, such as chronic migraine, reimbursement is possible if specific requirements are met – for example, prior documented ineffectiveness of other treatment options. If coverage is not granted, patients should expect to pay around 200 to 300 euros per treatment, depending on the required dose. Since migraine is a chronic condition, botulinum toxin often represents a long-term therapy. For many affected individuals, however, this primarily means a significant improvement in quality of life.
Botox can provide an extremely effective treatment option for excessive sweating, also known as hyperhidrosis. In this condition, the sweat glands are excessively active, independent of external temperatures or physical activity.
Botox works by creating a nerve blockade responsible for excessive sweat production. It inhibits the release of acetylcholine, a neurotransmitter that stimulates the sweat glands to produce sweat. When Botox is injected into the affected areas of the skin – usually under the arms, on the palms, or the soles of the feet – it blocks the nerve communication and significantly reduces perspiration.
“The injections are administered directly into the affected areas, and the dosage is precisely calibrated. For example, if someone suffers from excessive sweating on the feet, exactly these regions can be treated with Botox to block the overactivity of the sweat glands. The effect sets in after just a few days and can last up to six to nine months. Many patients report a substantial reduction in sweating, often by more than 80%.
Repeated treatments are possible and can extend the effect even further, sometimes even leading to a long-term desensitization of the sweat glands. For many, Botox is therefore a valuable therapeutic option, especially when other conservative measures such as antiperspirants or iontophoresis have not delivered the desired results. Particularly in professional settings, where excessive sweating can quickly become uncomfortable, Botox offers patients a reliable solution to feel safe and comfortable again”, emphasizes Prof. Dr. Dr. Heindl.
The sustainability of the effect, however, depends on various factors, such as the individual body’s response to Botox and the frequency of treatments. Some patients experience long-term improvement and may require fewer follow-up treatments after several sessions. In some cases, the effect can even become more lasting over time, as the sweat glands can, to a certain degree, be “retrained” to produce less sweat.
While fillers were originally used primarily to fill wrinkles and restore facial volume, today they also play an important role in reconstruction and the treatment of various medical conditions.
Prof. Dr. Dr. Heindl comments: “Fillers, especially those based on hyaluronic acid, have long become indispensable in aesthetic medicine. They are used to restore lost volume, define contours, and fill wrinkles. But fillers also play a significant role in medical practice in a variety of areas. One example is reconstruction after trauma or surgery, such as in cases of scarring or tissue loss. Hyaluronic acid is also used in lip or palate augmentation, especially for functional speech or swallowing disorders.
Fillers are also used in the treatment of HIV-related lipoatrophy, in which subcutaneous tissue decreases. They are equally effective for correcting asymmetries caused by paralysis, such as in spasticity. Another interesting area of application is ophthalmology, particularly after the loss of an eye. In such cases, filler is used to restore tissue in the orbit (eye socket) as a basis for fitting a prosthetic eye, since the tissue tends to shrink over time”, and he adds:
“The choice of filler depends on various factors, particularly the molecular size, degree of cross-linking, and viscosity of the material. Very fine fillers are used for superficial lines, while more strongly cross-linked volume fillers are used for larger areas such as the cheeks, chin, or for scar correction. There is therefore no single ‘filler,’ but rather a wide range of options that are applied according to the patient’s needs”.
If patients are interested in Botox or filler treatments for medical reasons, they should keep several important points in mind to ensure the treatment is both safe and effective.
First and foremost, it is crucial to consult a qualified and experienced physician who has extensive knowledge in the use of Botox and fillers and experience in their medical application. This ensures that the physician applies the correct techniques and tailors the treatment to the patient’s individual needs.
“Ideally, physicians should come from specialties such as ophthalmology, neurology, dermatology, or plastic surgery. The medical indication must always be clarified and documented. A thorough consultation is essential before treatment: patients must be informed about possible side effects, alternative treatment options, the duration of the effect, and necessary follow-up care.
In the case of Botox, it is especially important to check whether the patient is taking any medications that could affect the results, such as muscle relaxants. For fillers, a detailed medical history regarding autoimmune diseases or allergies is critical. Another key point: under no circumstances should patients undergo treatment by non-medical personnel. This also applies abroad, where such procedures are sometimes offered on vacation – in my opinion, that is complete nonsense. The risk of complications is higher there, mainly due to improper technique and a lack of sterility.
When Botox and fillers are improperly applied, complications can indeed occur. But when applied correctly, Botox is extremely safe. The most common side effects are local and temporary, such as mild pain at the injection site, small bruises, slight swelling, or even fatigue. In very rare cases, systemic symptoms can occur. Specific risks with Botox include temporary muscle weakness – for example, drooping eyelids if the forehead is treated, or vision disturbances if injections are placed too high around the eyes. However, these effects are always reversible and disappear after a few weeks. That’s why with both Botox and fillers it really is true: less is more. It is always necessary to coordinate closely with the patient”, explains Prof. Dr. Dr. Heindl.
With fillers, the risks are definitely higher, especially if they are injected into blood vessels. One of the most severe complications is vascular occlusion, where vessels become blocked, leading to impaired blood circulation.
“The first signs are pain, paleness, or a cold sensation. Fortunately, such serious complications are very rare overall and occur mostly with inexperienced providers or treatments outside medical facilities. Training, experience, and the correct technique are truly crucial here”, says Prof. Dr. Dr. Heindl.
There are also children who suffer from severe migraines for whom Botox can be medically useful. But – and this is very important – Botox should only be used in children if there is a clear medical indication and if the child is able to cooperate during treatment.
Botox originally comes from medicine, not from the beauty industry. Its aesthetic use only became popular later.
“In fact, botulinum toxin was already used in the 1980s in neurology, for example to treat strabismus (crossed eyes) or eyelid spasms. Botox works by selectively blocking the release of acetylcholine at the motor endplates of muscles. So its first medical uses came from neurology, and only later was it discovered that Botox could also be used for aesthetic purposes. Of course, the name ‘botulinum toxin’ causes some unease, since ‘toxin’ does mean poison. But in reality, it is a relatively weak toxin that is completely broken down after use.
It is therefore not nearly as dangerous as it is sometimes portrayed. And naturally, when there is a medical indication – for example, patients suffering from severe chronic migraines – it is absolutely justified to inject the toxin in order to reduce suffering. But ultimately, it remains a personal decision for each patient whether they want an aesthetic treatment. Both Botox and fillers are elective procedures that everyone must decide for themselves. The key is that patients are well informed and that treatments are carried out by skilled professionals in a safe setting”, stresses Prof. Dr. Dr. Heindl.
At the private practice "New Aesthetic Vision" in Cologne, one of the leading institutions for aesthetic medicine, only top-quality products from trusted sources are used to guarantee the safety and success of treatments. Prof. Dr. Dr. Heindl strongly advises relying only on reputable providers and experienced physicians.
“A certain level of competence is absolutely necessary, and quality plays a major role as well. The medication used must be of the highest quality. We only use premium products from Germany – true top products that are not available on the open market. The price of these products is, of course, a major cost factor. If I were to use a low-grade filler from abroad that costs just one euro, I could sell it for 50 or 100 euros. But I would never use such a cheap product, where there are no quality controls or standards. That is simply irresponsible.
Patients must know what they are getting into. A 20-year-old girl interested in a treatment may not know how to distinguish between high- and low-quality products. She might see on Instagram that someone had a treatment and think it looks ‘cool’ or ‘pretty.’ But such a decision should never be made without careful consideration. That’s why it is so important to me that treatments are always carried out by specialists with the proper expertise. And of course, treatment must take place in a medical setting – not in a nightclub or similar venues. It’s about the quality of the products and, above all, the safety of the patients”, warns Prof. Dr. Dr. Heindl emphatically.
