Hyaluronic acid is one of the most widely used products in aesthetic medicine, thanks to its moisturising and volumising properties and its natural results. However, like any medical procedure, hyaluronic acid filler injections carry certain risks that require special attention from doctors. In 2024, regulations and safety standards surrounding fillers are evolving to ensure safer practices and better protection for patients. This article looks in detail at these developments, the new guidelines for doctors and the importance of choosing products that comply with international quality standards.
Injections ofhyaluronic acidAlthough minimally invasive, these procedures are not without risks. Possible complications include allergic reactions, infections, bruising and, in rare cases, more serious complications such as skin necrosis or vascular embolism. For this reason, regulatory bodies and professional associations in aesthetic medicine set strict safety standards to minimise these risks and ensure patient safety.
In 2024, regulations will become even more rigorous, reflecting the growing demand for safe practices and high-quality results. Public health authorities such as the FDA (Food and Drug Administration) in the United States, Swissmedic (the regulatory authority for medicines and medical devices) in Switzerland and the EMA (European Medicines Agency) in Europe are introducing new directives that impose higher standards of quality, training and transparency on filler manufacturers and doctors.
The 2024 regulations focus on the quality of hyaluronic acid used in injectable products. Fillers must now meet strict criteria for composition, purity and safety. Products must be manufactured in facilities certified to Good Manufacturing Practices (GMP), with rigorous quality control throughout the production process.
In addition, they must undergo exhaustive safety testing, including clinical studies demonstrating their safety and efficacy. Practitioners must ensure that the products they use are approved by the relevant regulatory authorities, such as the FDA, Swissmedic or the EMA, and that they carry a CE (Conformité Européenne) mark for European Union countries.
In 2024, guidelines for doctors practising aesthetic medicine were tightened to improve the safety of hyaluronic acid injections. These new recommendations cover several aspects of practice, from initial training to injection techniques.
Patient safety starts with proper training for doctors. In 2024, it will be compulsory for doctors to undergo certified training in hyaluronic acid injection techniques. These courses include not only theoretical modules on facial anatomy and the properties of fillers, but also practical sessions supervised by experts.
Doctors must also comply with continuing education requirements, regularly attending refresher workshops and training courses on new injection techniques and technologies. This is important to ensure that doctors have the necessary knowledge and skills to carry out injections safely.
The new 2024 guidelines introduce standardised practices for hyaluronic acid injections. For example, the use of ultrasound imaging is becoming increasingly common to improve the accuracy of injections and avoid blood vessels to reduce the risk of vascular complications.
In addition, doctors must follow strict disinfection protocols before and after injections to prevent infection. The use of micro-cannulas rather than needles is also encouraged, as it minimises skin trauma and reduces the risk of bruising and bleeding. These standard practices are designed to optimise results while guaranteeing patient safety.
Even with optimal practices, complications can arise. The 2024 guidelines therefore stress the importance of doctors being prepared to manage potential complications. Every practice must have a detailed emergency plan and rapid access to the medicines needed to treat complications such as vascular embolism.
Practitioners must also be trained in the use of hyaluronidase, an enzyme that dissolves hyaluronic acid, in order to rapidly treat complications such as vascular occlusion or over-corrections. Communication with patients on the potential risks and management of complications is also an integral part of the new guidelines.
Technological advances are playing a crucial role in improving the safety of hyaluronic acid injections. In 2024, a number of technological innovations will enable doctors to carry out safer and more precise injections.
Ultrasound imaging is one of the most important technologies for injection safety. By enabling practitioners to see subcutaneous structures in real time, this technology helps to avoid blood vessels and inject hyaluronic acid in the right place, minimising the risk of serious complications. It also allows post-injection assessment to check that the product is being distributed correctly and to detect any irregularities.
Automated injection devices, such as injection pens, offer greater precision and uniform distribution of the product. These devices make it possible to control the exact amount of hyaluronic acid injected at each point, reducing the risk of over- or under-injection. They are particularly useful for treatments on delicate areas of the face, such as the lips or eye contour, where millimetre precision is essential.
These systems are interesting for doctors who are not completely experienced.
Artificial intelligence (AI) and big data are also transforming the field of aesthetic medicine in 2024. AI software can analyse a patient's facial features and predict the results of a hyaluronic acid injection, helping practitioners plan personalised treatments and anticipate possible reactions. These tools can also monitor trends in complications, helping to continuously improve safety protocols.
Patients are becoming increasingly aware of the potential risks associated with hyaluronic acid injections and are looking for practitioners who adopt exemplary safety practices. They now expect full transparency about the products used, the practitioner's qualifications and the procedures in place to manage any complications.
The new guidelines also emphasise the importance of communication with the patient. Doctors must clearly explain the potential benefits and risks of hyaluronic acid injections and obtain informed consent before any procedure. They must also be available to answer patients' questions and concerns at every stage of the process.
Post-treatment follow-up is also crucial to ensure patient safety and satisfaction. Doctors need to provide careful follow-up after injections to detect any complications early and intervene if necessary. Post-treatment follow-up helps to build patient confidence and ensure optimal results.
In 2024, the safety of hyaluronic acid injections relies on a combination of rigorous regulations, advanced technologies and best practice on the part of doctors. The adoption of new standards and guidelines, the integration of innovative technologies such as ultrasound imaging and automated injection devices are important to minimise risks and maximise patient satisfaction.
For patients, choosing a practitioner who is qualified, well-trained, experienced and transparent about his or her practices is a guarantee of a safe and satisfactory procedure.
