Hyaluronic acid


What It Is, How It Works, and Why You Should Choose the Multidimensional Approach


Small molecules for big results: often the most significant changes occur at the microscopic level, and this is especially true when it comes to cosmetics and skincare. In this article from our #BeautyBlog, we’ll take a closer look at a very important active ingredient: hyaluronic acid.

Properties and Effects

Hyaluronic acid is a substance naturally produced by our bodies and is one of the most important components of human connective tissue. The skin’s elasticity and softness depend largely on the presence of hyaluronic acid in the various layers of the dermis, which explains why it is such a widespread and popular ingredient in the world of cosmetics.
What makes it so effective is its
unique chemical structure, which allows it to be highly water-soluble and to bind a large number of water molecules to itself, thereby providing a one-of-a-kind moisturizing effect.

Unfortunately, as we age, the amount of hyaluronic acid in our bodies tends to decrease, accelerating skin aging: the skin loses its softness, tone, and elasticity, and the first wrinkles begin to appear. 


Multidimensional Hyaluronic Acid

We now understand just how important hyaluronic acid is for skin beauty, which explains why it is such a common ingredient in cosmetic products, especially anti-aging ones.

So how do you choose the most effective hyaluronic acid-based formulas? Cosmetic research has led to the development of a special multi-molecular-weight hyaluronic acid formulation: this means that the molecules within it have different sizes to reach the various layers of the skin.



To date, the most advanced versions of multidimensional hyaluronic acid are the so-called “4D” ones, meaning they have four different molecular weights

• the larger molecules act on the outermost part of the epidermis (known as the stratum corneum)

• while the smallest molecules are “salified” so they can reach as far as the dermis itself, deeply hydrating the skin

Ideal for combination and oily skin

Hyaluronic acid is a miracle ingredient for all skin types, but it’s undoubtedly the best choice for those with combination or oily skin: this is because it maintains skin hydration without leaving a greasy residue, providing a plumping effect without weighing down the skin.
