WHAT IS HYALURONIC ACID?Hyaluronic Acid is a crucial substance that bathes our cells and is one of the body's most vital naturally occurring components. This sugar is produced by our own cells and is found naturally in the epidermis and dermis, making it a key component for skin hydration and plumpness.
As a natural jellified molecule, Hyaluronic Acid acts as a biological sponge, constituting the skin's ""biological water bank"" and can retain more than 1000 molecules of water. Skin contains 50% of the total body content of Hyaluronic Acid, and while almost all cell types can produce it, its synthesis slows down with time, resulting in decreased amounts of Hyaluronic Acid in the skin, leading to dehydration and loss of plumpness.
Dermatologists recommend including Hyaluronic Acid in the skincare routine to re-plump the skin and reduce the first signs of aging. It is noteworthy that Hyaluronic Acid is constantly produced, with a lifespan of only one day before it is naturally degraded in the skin.
Did you know that Hyaluronic Acid plays a crucial role in maintaining skin and hair hydration and plumpness, making it an essential ingredient in many beauty products?
WHAT DOES HYALURONIC ACID DO FOR SKIN?
Hyaluronic Acid is a naturally occurring substance that is constantly produced by cells and degraded by enzymes known as hyaluronidases. However, as we age, the amount of Hyaluronic Acid in our skin begins to decrease due to an imbalance between its production, which slows down with age, and its degradation, which accelerates. This decline in Hyaluronic Acid production and increased degradation can result in the loss of the skin's natural ability to retain water, leading to a lack of suppleness and the appearance of dehydration lines. This is the first sign of premature aging.
Moreover, external factors such as UV exposure and pollution can cause oxidative stress, which further accelerates the degradation of Hyaluronic Acid. Other lifestyle factors such as nutrition, tobacco use, stress, and sleep deprivation can also contribute to oxidative stress and accelerate Hyaluronic Acid loss.
Did you know that Hyaluronic Acid not only acts as a biological moisturizer in the epidermis, but also helps sustain collagen production in the dermis? Both molecules are responsible for maintaining skin plumpness and suppleness. In the long term, when the Hyaluronic Acid rate decreases in the skin, collagen production is also affected.
It's essential to include Hyaluronic Acid in your skincare routine to combat premature aging and maintain hydrated, plump, and supple skin.

WHAT ARE THE BENEFITS OF HYALURONIC ACID FOR THE SKIN?L’Oréal Paris is committed to using a biodegradable, biocompatible, and biomimetic form of Hyaluronic Acid in our skincare products. This innovative ingredient is formulated using a lactic bacteria fermentation process, inspired by nature and highly tolerable for all skin types and tones. Our Hyaluronic Acid is of the highest quality and is indicated on our product ingredient lists as either Hyaluronic Acid, Sodium Hyaluronate, or Sodium Acetyl Hyaluronate.
WHICH HYALURONIC ACID SHOULD I LOOK FOR?
Using different types of Hyaluronic Acid is essential to achieve comprehensive benefits for the skin. It is important to address both surface dehydration and deeper wrinkles to slow down the signs of aging. At L’Oréal Paris, we incorporate three types of Hyaluronic Acid in our superior formulas to ensure maximum effectiveness: two pure Hyaluronic Acid types and one acetylated form:
HIGH MOLECULAR WEIGHT HYALURONIC ACID: This type of Hyaluronic Acid is able to provide an immediate replenishment of moisture to the skin. Macro Hyaluronic Acid refers to high molecular weight Hyaluronic Acid with a superior weight of over 1000kDa. It has a strong affinity with the skin surface, allowing for rapid hydration and smoothing of fine lines caused by dehydration.
MICRO MOLECULAR WEIGHT HYALURONIC ACID: penetrates deeper to provide deep hydration. Micro Hyaluronic Acid (low molecular weight up to 50 kDa) can penetrate the epidermis and provide in-depth moisturization. It helps to reduce skin roughness and stimulates the natural production of Hyaluronic Acid in the skin.
MICRO-EPIDERMIC HYALURONIC ACID: has been scientifically demonstrated to penetrate the skin and provide a comprehensive anti-wrinkle effect by slowing down the degradation of both Hyaluronic Acid and collagen, another important molecule for skin plumpness. Micro-Epidermic Hyaluronic acid (very low molecular weight, specifically 25kDa) is a unique type of Hyaluronic Acid that helps to replump and protect the skin's collagen, providing a more youthful and vibrant appearance.
L’Oréal Paris is a skincare expert when it comes to formulating products with Hyaluronic Acid. We have developed several formulas that cater to specific skincare needs and have conducted 7 clinical studies with a panel of 200 patients to test their effectiveness. What's more, our Hyaluronic Acids are obtained from biotechnology through a process of biofermentation using lactic bacteria fed with cereal grown in the same geographic region. We use green science to acetylate our micro-epidermic Hyaluronic Acid. All of our Hyaluronic Acids are produced in France and Switzerland, ensuring the highest standards of quality and sustainability.
WHAT IS MICRO EPIDERMIC HYALURONIC ACID?
L’Oréal Paris uses a unique type of Hyaluronic Acid called micro epidermic acid, which is designed to be smart and effective. This micro Hyaluronic Acid is tagged with a signature that cells produce to protect their own molecules from degradation. By marking the HA with this tag, it enhances the life span of the molecule in the skin, making it efficient for a longer period. Clinical studies on L’Oréal Paris' micro epidermic Hyaluronic Acid have shown it to be 13 times longer lasting in the skin.
Fun fact: Micro Hyaluronic Acid used in filler injections has been shown to boost collagen synthesis, which is responsible for the plumpness and firmness of the skin.
HOW AND WHEN SHOULD WE START INCORPORATING HYALURONIC ACID INTO OUR SKINCARE ROUTINE?
Incorporating hyaluronic acid into your skincare routine is a great way to improve the hydration and overall health of your skin. It's a universal need, and it's never too early or too late to start using it. L'Oréal Paris offers a range of biocompatible and bioavailable hyaluronic acid products suitable for all skin types, including sensitive skin. You can use hyaluronic acid products as often as you like, morning and evening, before applying any other skincare products. Layering multiple hyaluronic acid products in your routine, such as serums, day and night creams, can increase moisture and help other ingredients penetrate the skin more effectively.
WHAT IS A GOOD ANTI-AGING SKINCARE ROUTINE?
If you're looking for an effective anti-aging skincare routine, there are several things to consider. Your goals may include improving hydration, reducing the appearance of fine lines and wrinkles, plumping the skin, and brightening dark spots. Different active ingredients can be used to address these concerns, either individually or in combination.
For a comprehensive anti-aging approach, we recommend incorporating two powerhouse ingredients: hyaluronic acid and retinol. Hyaluronic acid is a key molecule for retaining moisture in the skin, while retinol is a potent form of vitamin A that helps to boost collagen production and increase cell turnover, resulting in smoother and firmer skin.

What are the differences between hyaluronic acid and retinol?
Retinol, on the other hand, is a powerful derivative of vitamin A and a well-known anti-aging active. It works by increasing the rate of cell turnover, which helps to visibly renew the skin, improve texture, and reduce the appearance of fine lines and wrinkles. When used together, hyaluronic acid and retinol can provide a potent anti-aging effect, hydrating and plumping the skin while also smoothing and rejuvenating its appearance.
