Hyaluronic Acid for the Face:
What Is It and What Is It for?

Who has never heard of hyaluronic acid? Today you can find it in dozens of cosmetics: moisturizers, serums, cleansers and many other facial skin care products.

But what exactly is hyaluronic acid? What benefits does it offer to the skin? And why is its molecular weight so important?

Read the article and find out the answer to all these questions about this essential element for every beauty routine.


Hyaluronic acid is a substance found naturally within the connective tissues of the human body, particularly in the skin, eyes and joints.

It is an essential component for the skin, because it gives skin structure and allows it to maintain its shape.

After 25 years of age, hyaluronic acid production decreases exponentially, along with other key elements such as elastin and collagen.

The result? The skin loses volume, hydration, and firmness, and the first wrinkles and blemishes begin to appear.


What is the biggest benefit you can get from this valuable substance? It will restore skin radiance that is slowly diminishing over the years.

In particolare, sono 2 le proprietà che questa sostanza possiede:

  • proprietà idratanti
  • Anti-wrinkle properties

Let's see in detail what they mean:

Moisturizing properties

What makes hyaluronic acid a very special substance is the fact that it can hold up to 1000 times its weight in water. What does it mean?

Basically, it works as a humectant — as it is able to retain water molecules on the surface of the skin — keeping the skin tight and hydrated.

What is interesting is that this action takes place on 2 skin levels:

  • on a deep level:plumps the skin and gives it volume;
  • on the surface:gives the skin a softer and more elastic appearance.
Anti-wrinkle properties

In addition to this powerful moisturizing action, cosmetics that contain hyaluronic acid are very effective in reducing wrinkles and fine lines.

Due to its effective protective action, it frees the skin from the "strain" of retaining moisture, thus promoting skin cell regeneration.

Integrating a moisturizer or a serum with hyaluronic acid into your beauty routine can really help keep your facial skin toned and hydrated, preventing blemishes.

Pesi molecolari dell'acido ialuronico


The effectiveness of a cosmetic containing hyaluronic acid is closely linked to the molecular weight and it's concentration within the product. In other words, the size of its molecules also determines its function.

In base all’effetto che vorrai ottenere sulla tua pelle, dovrai quindi prestare attenzione al peso molecolare dell’acido ialuronico presente nei tuoi prodotti di bellezza.

Acido ialuronico ad alto peso molecolare

The large size of its molecules do not allow it to pass through the skin. However, it can act effectively on the surface of the skin, performing a moisturizing, protective and refreshing action.

Hyaluronic acid with medium molecular weight

This type of molecule can be absorbed more easily, but cannot reach the deepest layers of the skin. However, it allows water to pass through, thus maintaining good hydration.

Hyaluronic acid with low molecular weight

This is the most precious type for the skin, because it's small size allows these particles to reach the deepest layers of the skin. In this way, they are able to nourish, plump and invigorate more effectively.

Note that some cosmetics allow these 3 levels of concentration to be exploited synergistically.

An example is Phynour's SUPREME HYALURONIC³ SERUM. Using pure hyaluronic acid with high, medium and low molecular weight, it allows to hydrate and tone all of the skin layers. The result will be a relaxed, nourished and plumped skin, with a renewed radiance.
