femme injection d'acide hyaluronique


Hyaluronic acid has this interesting feature: it is found in our skin but also all human and animal organs. So it is a molecule with very high biocompatibility.
It is the same molecule found in the syringe of the doctor performing an aesthetic treatment.

Hyaluronic acid-based injectables are the most popular treatments after neuromodulators.

This molecule is sparking such enthusiasm and interest that one can only ask the following question: what is hyaluronic acid, and what are its sought-after effects?

What is hyaluronic acid?

This molecule from the polysaccharides (sugars) family has been known since 1934. Naturally present in the human body, it is most abundant in the skin, and it is where this molecule acts like a sponge.
Indeed, it retains water in tissues.
As such, hyaluronic acid is responsible for the plumpness of the skin and the freshness of the complexion.

Over time, the body production of HA declines by 6% each decade. This natural aging process of the skin causes sagging skin and the appearance of fine lines and wrinkles.

One can ward off this decrease by using synthesized formulas and aesthetic treatments.

Hyaluronic acid effects

The popularity of hyaluronic acid is due to its many properties.

Thanks to its ability to retain water, hyaluronic acid plumps up the skin and reduces the appearance of fine lines and wrinkles. Therefore, it is a welcome addition to skin that is lacking in moisture. On the other hand, the implantation process partially stimulates collagen production—the result is smoother features and a plumper look.

It is also a molecule suitable for all skin types without exception, even the most sensitive. Furthermore, over time, hyaluronic acid breaks down naturally in the body.

Which face care to adopt?

Different types of face care are available to compensate for the drop in hyaluronic acid’s natural production.

  • Day creams for surface action and a plumping effect
    The hyaluronic acid molecule in these treatments has a larger molecular weight. They, therefore, retain water on the skin’s surface to hydrate it.
  • Masks for a deeper revitalizing action
    Masks can be in cream or fabric form, and they are more heavily dosed. Their moisturizing texture effectively smooths out features and provides deeper revitalization. However, the effect is fleeting. Hence the need to institute this kind of care frequently.
  • Anti-aging complexes for a firming action
    In addition to low molecular weight HA that reduces skin evaporation and retains water, these treatments contain other restructuring active ingredients (Retinol, fruit acids) and antioxidants (such as vitamin C and E) to regenerate skin from the inside.

Ha dermal filler injections

Hyaluronic acid can be injected under the skin to correct several aging signs and disgraces in the face. The injections will also compensate for the decrease in hyaluronic acid’s natural production. The hyaluronic acid will work by filling in or creating the volume needed.

Unlike the HA molecules used in face care, the injected hyaluronic acids will be deposited below the dermis and epidermis for a more in-depth effect. This process captures water, giving a volumizing effect, and deeply hydrates the skin.


Hyaluronic acid micro-injections combined with antioxidant and multivitamin active ingredients are performed for a revitalizing radiant effect on the face, neck, and décolleté.

This treatment is highly recommended after the summer. The only downside is that it is a treatment with a fleeting effect. We, therefore, recommend scheduling biennial maintenance sessions.

Is injected hyaluronic acid the same as that used in cosmetics?

The primary molecule is the same, except that the hyaluronic acid used by injection is crosslinked.

That is, the molecules are linked together to form a viscoelastic gel. When injected into the wrinkle, it fills the depression. Hence the name filler injection. Of course, the effect also lasts longer because the HA is injected deeper.

The greater the crosslinking of the molecule, the thicker the gel and the more resistant it is.

Nevertheless, to keep the natural effect of the result, it must remain flexible and move under the skin.

The natural results are significant proof of the doctor’s expertise.

Is it possible to combine filler injections with other anti-aging treatments?

Since it is a natural product, combining it with other cosmetic products, such as Botox®, should be no inconvenience.

During the consultation, the doctor will determine whether there are any contraindications.

It is common and advised to combine dermal filler injections with neuromodulators in some cases.
Neuromodulators relax the muscles responsible for wrinkles and prolong the effects of fillers.
