What is hyaluronic acid?

Hyaluronic acid is a natural molecule found in the human body, primarily within the skin, connective tissues, and eyes. It is renowned for its remarkable ability to retain moisture, holding up to 1,000 times its weight in water. This characteristic makes it a vital component in maintaining skin hydration, elasticity, and volume. In the medical and cosmetic industries, hyaluronic acid is widely used in the form of injectable fillers and topical skincare products, owing to its biocompatibility and its role in tissue repair and regeneration. Its unique viscoelastic properties also make it beneficial in joint lubrication and wound healing applications.

Why do we need hyaluronic acid injection?

As we age, our skin loses collagen, elastin, and hyaluronic acid, leading to dryness, loss of elasticity, and the formation of wrinkles. Hyaluronic acid injections are a popular anti-aging treatment because they can effectively address these issues by providing immediate hydration, volume, and stimulating collagen production, helping to restore a more youthful appearance to the skin.

This aging process starts after the age of 20 ; a well-structured lifetime treatment plan can help you maintain your youthfulness for a very long time.

My lifestyle can worsen my aging process?

The aging process of the skin is profoundly impacted by lifestyle choices and external environmental factors. Prolonged sun exposure leads to photoaging, characterized by wrinkles and loss of elasticity, while smoking impedes blood flow, accelerating wrinkle formation. Dietary habits play a crucial role; diets high in sugar and refined carbs can damage skin collagen, whereas antioxidant-rich foods protect against damage. Environmental pollution contributes to aging by creating harmful free radicals, and chronic stress affects the skin's moisture retention and can break down collagen. Adequate sleep is essential for the skin's repair and regeneration, and regular exercise enhances blood flow, nourishing skin cells. By addressing these factors, individuals can significantly influence their skin's aging process, maintaining a healthier and more youthful appearance over time.

Is there different type of hyaluronic acid?

In the realm of injectable products, hyaluronic acid (HA) varies mainly in terms of cross-linking and density, which helps to meet different cosmetic needs. For example, denser fillers are ideal for bone restructuring, such as chin or cheekbone augmentation, as they help to increase bone support. Another type of product can provide significant volume in areas like the mid-face or temples, offering a robust framework and pronounced contouring. Conversely, fillers with a smoother, less dense consistency are preferred for natural lip augmentation or addressing fine lines and wrinkles. This customization in HA fillers allows for targeted treatments, ranging from deep structural work to surface-level aesthetic enhancements. The doctor's role is to choose the right product for the appropriate area to achieve the best natural aesthetic look.

Why should I get my injections done by a doctor? My beautician is offering me a very good deal for my lips

Opting for a doctor over a beautician for injections, like lip fillers, is crucial for safety and quality. Doctors possess in-depth medical knowledge and understand facial anatomy, ensuring procedures are performed safely and effectively. They use high-quality, medical-grade products and are trained in precise injection techniques, crucial for natural-looking results. Additionally, doctors can assess your suitability for the procedure, considering your health history, and are equipped to handle any complications. While beauticians might offer attractive deals, the risks and potential for unsatisfactory outcomes are significantly higher


Additionally, it's important to note that receiving injections from someone who is not a licensed medical professional is not only risky but also illegal. Such unauthorized practice can lead to severe legal consequences, including up to 2 years in prison and fines exceeding 100,000 euros.

What are the risks of hyaluronic acid injections?

We can divide this answer in 2 distincts paragraph:


Severe Risks of Aesthetic Injections:

The most serious risks associated with aesthetic injections include embolism, skin necrosis, blindness, and cerebral stroke. An embolism can occur if the injected filler enters a blood vessel, potentially leading to life-threatening complications. Skin necrosis happens when the injection obstructs blood flow, causing tissue death. Blindness, although extremely rare, can result from injections around the eyes affecting ocular blood vessels. Cerebral stroke is another grave risk, albeit rare, where an injection near facial blood vessels impacts cerebral circulation.

Other Risks of Aesthetic Injections:

Apart from these severe risks, there are more common but less dangerous complications. These include allergic reactions to the injected substances, infections at the injection site, bruising and swelling, and facial asymmetry due to uneven product distribution. Unsatisfactory results, requiring further touch-ups or corrections, are also a possibility. Additionally, there's a risk of granuloma formation, where nodules develop around the injected material, sometimes necessitating medical intervention. It's important to have a thorough consultation with a healthcare professional to understand and mitigate these risks.

Can I have filler injections while I'm pregnant or breastfeeding?

It is generally advised to avoid filler injections during pregnancy and breastfeeding. The safety of these cosmetic procedures for pregnant or breastfeeding women has not been extensively studied, and there is a lack of conclusive evidence to ensure their safety for the fetus or nursing infant.


The body undergoes significant hormonal changes during pregnancy and breastfeeding, which can affect how it reacts to treatments like fillers. Additionally, there's always a risk of infection or an allergic reaction with any injection, which could have implications for both the mother and the baby.

When can I resume sport activities?

After receiving filler injections, it's generally recommended to avoid strenuous physical activities for at least 24 to 48 hours. This precaution helps minimize swelling and bruising. While light activities like walking might be resumed quickly, more intense exercises, especially those increasing blood flow to the face, should be avoided for a few days. The specific area treated and individual healing responses also play a role in determining when to safely resume physical activities. It's crucial to follow the guidelines provided by your healthcare provider, as they will tailor advice based on your particular situation and the type of filler used. Giving your body adequate time to heal ensures the best possible results from the filler treatment.

Is it recommended to massage the area that has been filled?

Yes, for most hyaluronic acid fillers, light massage are recommended by the practitioner to smooth out the product and ensure even distribution. 

How long will the result of the fillers last?

The longevity of results from filler injections varies based on several factors. Typically, hyaluronic acid fillers last between 6 to 18 months, but this can differ depending on the type of filler used, the area treated, and individual factors like metabolism and lifestyle. Fillers in areas with more movement, such as the lips, may break down faster. The quantity of filler used and the skill of the injector also play a role in how long the effects last. Regular maintenance treatments can help prolong the desired results. It's important to have realistic expectations and discuss the anticipated duration with your healthcare provider
