Hyaluronic Acid: Benefits, Uses and Applications for Lips and Dark Under-Eye Circles
Hyaluronic acid is one of the most demanded aesthetic treatments nowadays due to its multiple benefits for the skin and its ability to improve the appearance of different areas of the face. Its application is especially popular for the lips and dark circles under the eyes, as it can correct imperfections, add volume and rejuvenate the skin without the need for invasive surgery.
Below, we will explore in detail what hyaluronic acid is, its main benefits and why it is essential to go to a specialised clinic such as Planas Salud Medicina Estética to guarantee safety and optimal results.
What is Hyaluronic Acid?
Hyaluronic acid is a natural substance present in our body, mainly in the skin, cartilage and synovial fluid of the joints. Its main function is to maintain the hydration and elasticity of tissues, as it has the capacity to retain large quantities of water.
However, as we age, the body’s production of hyaluronic acid decreases, leading to a loss of firmness, hydration and volume in the skin. This reduction contributes to the formation of wrinkles, fine lines and facial sagging.
In aesthetic medicine, hyaluronic acid is used in the form of an injectable gel to restore volume, hydrate the skin and smooth the signs of ageing. It is a safe, biocompatible and resorbable treatment, which means it is naturally assimilated by the body over time.
Main benefits of the treatment
Hyaluronic acid is a highly effective treatment that offers a number of aesthetic and functional benefits:
- Deep hydration: Retains water in the skin, improving its texture and radiance.
- Facial rejuvenation: Reduces wrinkles and expression lines progressively.
- Immediate and natural results: A visible improvement is observed from the first application.
- Minimally invasive procedure: No surgery and no long recovery time.
- Biocompatible and resorbable: Being a natural substance in the body, it degrades progressively without generating unwanted permanent effects.
