The power of water

Hydration is essential not only for our skin, but also for the proper functioning of our body, regardless of our age. 360-degree hydration means acting from both the inside and outside.

Many geological eras have passed since we were fish swimming in a primordial sea, but since then water has never stopped to be the most important element in our lives. Hydration is the foundation of our health and the proper functioning of our organs. And if we consider that skin is our largest organ, the importance of proper hydration at 360 degrees becomes essential to ensure optimal state of our skin. If our organism has water deficit, our skin will be the first to visibly show the signs.

Drinking water helps us to restore the hydration our body has lost during metabolic processes, through sweating, breathing, and when removing toxins. Water is therefore a fundamental nutrient for our daily physiological functions that include proper digesting, keeping our skin healthy and lubricating our eyes and joints. It is therefore important to ensure we drink enough water for our body’s needs.

How much water?

Keep in mind that almost 20% of our water intake comes from food. Fruit, leafy vegetables, peppers and cucumbers are just some of the foods that are useful for this purpose. According to recent studies conducted on caffeine-based drinks, like tea and coffee, these drinks can also be counted as part of our daily water intake, despite what was believed in the past.

How can we ensure that our water intake is sufficient? Without doubt, the first thing to do is to listen to your body. The thirst stimulus remains a fundamental indicator, but it is not enough on its own. This is because the mechanisms that regulate fluids and stimulate thirst decrease over time. Moreover, with children and sometimes with athletes, thirst stimuli alone are not enough to protect against the risk of dehydration.

So, how much water should we drink? European Food Safety Authority (EFSA) guidelines give us a general idea of how to regulate this by taking into account a number of variables, including age and gender.

For example, for adults and the elderly:

  • women 2 l/day
  • men 2.5 l/day
Moisturizing your skin from the outside

There is no skin that does not benefit from correct hydration: young or mature, male or female, dry or combination, every skin benefits from sufficient water intake that should come from the inside, but also the outside, via an appropriate skincare treatment.

There are various ingredients that help moisturize the skin, but one of the best known and most hyped is, without doubt, hyaluronic acid. This acid is already naturally present in our organism. In fact, it is one of the components of our connective tissue. It can be found in our joints, our eyes and, at a greater level, in our skin. It is the presence of hyaluronic acid that allows our skin to maintain its form and elasticity, and to heal, in the case of a cut or wound. A loss of hyaluronic acid provokes dehydration and premature skin tissue ageing. Naturally the production of hyaluronic acid decreases with age. This is why a skincare, which is aimed to restore proper hydration of the epidermis, is useful.  

What is hyaluronic acid

Hyaluronic acid is a glycosaminoglycan, a molecule that is widely present in our extracellular matrix, i.e. the amorphous substance that surrounds our cells and acts as both a “support” and a communication channel between them.

Discovered in the 1930s, hyaluronic acid has been studied widely since then to understand its fundamental role in the physiological processes of our cells.

Let’s look at it in greater detail. Hyaluronic acid belongs to the category of humectants, i.e. the molecules that capture and retain water. As we have seen, it is already naturally present in our tissues, and for several decades now it has been used in most cosmetic face cream and serum formulations.

But how does hyaluronic acid work?

Its range of action is closely linked to its size, as it can have a high and low molecular weight. High molecular weight hyaluronic acid, which has a larger molecule, remains on the surface of the skin and keeps the external layer of the epidermis hydrated. Low molecular weight hyaluronic acid, on the other hand, being smaller in size, retains less water, but is able to penetrate deeper into the epidermis, ensuring the hydration of the layer immediately below it. The ideal solution is to look for skincare products that contain different molecular sizes of hyaluronic acid. When it is used, the skin remains hydrated and appears visibly enriched and smooth. It is therefore able to protect itself, too, by creating a surface barrier that stops water dispersion over time.

Our tests

During the development of Aeqium products we conducted numerous trials and studies to test our formulations. One of these had the following result: after 60 days of using the face cream combined with nutraceuticals, a 44% increase in skin hydration was registered, combined with a visible improvement of the state of the skin barrier and a visible reduction in expression wrinkles.

Keeping your skin hydrated is essential for it to perform its main function: protecting us.

The range of moisturizing products on the market is incredibly varied, but it is important to opt for solutions that are the result of extensive scientific research, with a state-of-the-art formulation and top-quality ingredients. Beyond the undisputed aesthetic benefits of moisturized skin, it is important to remember that the health of our skin depends on health of our body.
