o que é ácido hialurônico – When it comes to aesthetic procedures that improve the appearance of the face, Hyaluronic Acid is one of the most popular. It is known to offer a more harmonious and youthful appearance, but sometimes there are still many doubts.

It is important to clarify them, especially for those considering this treatment. This allows you to move forward with the process more consciously.

Using face creams with hyaluronic acid as an active ingredient, like L’Óreal Paris’ Revitalift Hyaluronic acid, is one of the best ways to reap the benefits of this beneficial ingredient for the skin. However, in these situations, you must apply and use the anti-wrinkle product correctly, you know?

That’s why today we will answer some of the most common questions about Hyaluronic Acid for Facial Rejuvenation.

o que é ácido hialurônico – Hyaluronic Acid: What is it?

Our bodies naturally contain hyaluronic acid, made up of sugar molecules. It can be found in many kinds of tissue, including cartilage, joints, skin, and eyes. Hyaluronic acid is a naturally occurring moisturizer and collagen-producing stimulant that keeps skin youthful and healthy. However, the body loses this substance as cells age and time goes on. Resetting is, therefore, required.

Replacement is typically done with cosmetic products, such as creams and serums or hyaluronic acid injections. For injections, look for specialized aesthetic clinics. As for cosmetics, you can let NIVEA take care of you.

Hyaluronic Acid is a natural active ingredient produced by the body with moisturizing and collagen-stimulating properties. Still, over time, its production decreases, making it necessary to undergo treatment to replace it.

Hyaluronic Acid is an active ingredient highly recommended by dermatologists and recognized worldwide due to its numerous benefits for the skin.

What is Hyaluronic Acid Used for?

The main functions of hyaluronic acid fall into two broad categories. The first, hydration, includes benefits such as softness, smoothness, and shine. Then, hyaluronic acid helps to revitalize the skin’s texture, ensuring more significant support and preventing sagging.

However, this is just a cursory look at the ingredients. Learn a little more about the revolutionary properties of hyaluronic acid!

1 – Combat Early Aging

As time passes, our body loses some of its characteristics. In general, this change results from hormonal changes or a drop in the production of some substances. The best example is collagen, a protein responsible for the skin’s elasticity and resistance.

Furthermore, it is also present in the composition of tissues such as muscles and bones. Aging decreases collagen production, which can cause sagging and reduced facial volume, especially the lips.

To slow down the process, hyaluronic acid stimulates the work of fibroblasts, the cells responsible for producing collagen in our body.

2 – Reduce Wrinkles And Expression Lines On The Face

In addition to sagging, the absence of collagen in the skin also causes wrinkles and expression lines on the face, known as dynamic wrinkles. Wrinkles appear as the skin ages, caused by the loss of elasticity and volume.

They can be of natural origin, such as the repeated movement of facial or external muscles. In this case, they are caused by pollution, sun exposure, lack of sleep, and dehydration. Using cosmetics and treatments with hyaluronic acid is a successful option for reducing wrinkles and expression lines on the face.

3 – Provide Greater Hydration To The Skin

Hyaluronic acid has a unique characteristic: it carries within it around a thousand times its weight in water. Therefore, one of its most significant functions is to provide greater hydration to the skin. For this reason, the absence of hyaluronic acid can cause dry skin. That’s why you need to replenish this substance as your body ages.

However, hyaluronic acid hydrates the skin and can retain liquids and preserve the existing hydration. This way, your skin is protected against external factors that cause dryness, such as excessive heat and cold and hot baths.

4 – Promote Filling And Anti-Sagging Action

By hydrating the body, hyaluronic acid also performs another critical function: it fills the spaces between cells. This filling action causes the skin to gain greater volume, becoming smoother and more uniform because hyaluronic acid stimulates the skin’s collagen production; its filling effect also helps lessen the signs of aging brought on by the loss of this protein. However, collagen and hyaluronic acid are not the only skin properties that suffer decline over time.

Along with them, it is also necessary to replace the skin’s elastin to prevent sagging. Elastin is the protein that gives firmness and support to the skin, as it is present in the structure of the body’s tendons, ligaments, and elastic fibers. To prevent the loss of elastin in the skin, it is vital to eat green vegetables, vitamin C, and omega 3.

How to Apply Hyaluronic Acid?

We can use Hyaluronic Acid for at least three purposes:

  • In young patients who want to make minor improvements to their face (such as filling lips or dark circles, profile correction, among others)
  • Preventing aging, hydrating the skin, replacing small volumes, and filling in some lines or wrinkles that may begin to appear
  • Treatment of signs of aging in which, together with other therapies, we can obtain good results.
  • We can support the skin, restore contours and volume to the face, and fill in unwanted wrinkles.

Main Benefits of Hyaluronic Acid

  • Recover skin tone and firmness;
  • Return volume to areas where it was lost;
  • Moisturize the skin;
  • Reduce wrinkles and lines on the face;
  • Cover any gaps;
  • Restore skin support;
  • Redefine the contours of the face;
  • Improve facial harmonization.

How to Use Hyaluronic Acid?

Hyaluronic acid is one of the most used and loved ingredients in the world of skincare. But how do you use this ingredient, how often, and – most importantly – is it safe?

Firstly, we will explain, in a straightforward way, how to use hyaluronic acid. This ingredient should be applied twice daily, in the morning and before bed.

Many products contain hyaluronic acid, from moisturizing creams to serums. This powerful humectant can be used every day, but it can be part of products with ingredients that are not suitable for daily use. So, don’t be afraid of hyaluronic acid, but always follow the instructions for using your products.

Use a serum with hyaluronic acid when your skin is still damp after washing or using toner. This will help the ingredients penetrate and settle into the skin. Furthermore, if you also want to use a serum with niacinamide, we recommend using the one with hyaluronic acid first. This will help you get the most out of your products.

How is Hyaluronic Acid Produced?

As previously stated, hyaluronic acid is a substance naturally produced by the human body and other mammals. However, when extracted from animal tissues that contain proteins and DNA, there is a potential risk of adverse immunological reactions. Therefore, the industry has also found ways to produce hyaluronic acid artificially, in much more resistant versions, through various biotechnology techniques.

One of them is the fermentation of plant substrates, carried out by bacteria of the genus Streptococcus. Another possibility is the fermentation of beet sugar by lactobacilli. The truth is that each institution responsible for the substance production process works with the most convenient technique.

Does Hyaluronic Acid have Side Effects?

Because hyaluronic acid is produced by the body naturally, side effects are uncommon. At low incidence, accidents involving hyaluronic acid can happen with the applicable version of the substance when done incorrectly. The acid is absorbable and biocompatible with the human body for creams and serums.

And speaking of acid, don’t be fooled: hyaluronic acid doesn’t burn the skin. Acids are safe substances and are part of several processes in the body, such as the digestive process. Acids are also present in foods like fruits, coffee, milk, and derivatives.

Can We Use Hyaluronic Acid Everyday?

Yes. Daily use of hyaluronic acid is ideal for your skin. Many people get worried about the word “acid,” but this is a very gentle acid. Not only can it be used daily, it can be used twice daily.

Over time, it will help maintain your skin’s hydration. Therefore, it is an excellent ally for people with dry skin, but it can also be used, without fear, by those with oily skin!

Hyaluronic acid is necessary for people with mature skin or those seeking anti-aging products because it can help minimize the appearance of fine lines and wrinkles when used consistently.

The effects of hyaluronic acid are so well known that the ingredient has also been incorporated into many makeup product formulas!

Is Hyaluronic Acid Terrible?

No. Our bodies produce hyaluronic acid to maintain our health. Therefore, it can be found in both skincare products and dietary supplements. Of course, the molecules found in our products are produced safely in laboratories.

Hyaluronic acid also does not harm the skin’s natural pH and rarely causes irritation or allergies. It’s so gentle that it can be used on sensitive skin! Of course, be careful, as different products contain various concentrations of hyaluronic acid and many other ingredients.

Who can use Hyaluronic Acid?

Hyaluronic acid is a substance recommended for all skin types. However, it is especially recommended for dry or dehydrated skin due to its high hydration capacity. If you have oily skin or skin with blackheads and pimples, you can use hyaluronic acid without fear. Despite the hydration it provides, its interaction with these skin types is positive.

Be careful when choosing the product type: avoid creams and lotions that are more oily or greasy. On another note, mature skin benefits from hyaluronic acid by reducing the signs of aging. But that doesn’t mean that young skin doesn’t need the active ingredient. Remember: working with prevention is always an intelligent path.

How long does the effect of Hyaluronic Acid treatment Last?

o que é ácido hialurônico – Hyaluronic acid indicated for facial fillers lasts typically between 6 and 18 months.

This variation is due to the patient’s habits and lifestyle, the application location, and the hyaluronic acid characteristics.

o que é ácido hialurônico – Currently, hyaluronic acid is among the most used cosmetic fillers, being applied, for example, to fill wrinkles and even modeling facial contour through injectable applications. Few people know that hyaluronic acid, in addition to being a substance with a complicated name, supports, plumps, and hydrates the skin, among other functions.

But even fewer people know that hyaluronic acid is naturally produced by our body (and that of other mammals) and that injecting the substance into the body is not the only way to take advantage of its benefits. This is what we will explain in the article above, in which we will also talk about the benefits of the substance.
