Hyaluronic Acid for Skin, Hair & Makeup

Known as a modern day “skincare hero”, Hyaluronic Acid has quickly become one of the most famous ingredients when it comes to targeting smooth, hydrated, plumped and youthful skin. Hyaluronic Acid is also used in cosmetics in skincare to re-plump fine lines and wrinkles with moisture, prolong and maintain fillers injections and enhance skin quality. It is now used in L’Oréal Paris’ make-up foundation for these properties.

WHAT IS HYALURONIC ACID?

Hyaluronic Acid is the fundamental substance in which our cells bath. It is one of the body’s most important naturally occurring substances. This sugar, produced by our own cells and naturally found in the epidermis and dermis is a key component for skin hydration and plump.
Hyaluronic Acid constitutes skin’s “biological water bank” since it is a natural jellified molecule able to retain more than 1000 molecules of water, acting as a biological sponge.
Skin content in Hyaluronic Acid represents 50% of the total body content in Hyaluronic Acid. Almost all cell types can produce it, unfortunately, its synthesis slows down with time and its amount in skin decreases leading to dehydration and loss of plump. That’s why dermatologists recommend including Hyaluronic Acid in the skincare routine to re-plump skin and reduce first signs of aging.
Did you know?
Hyaluronic acid is constantly produced. It takes only 1 day to a Hyaluronic Acid molecule to be produced and degraded naturally in skin.

WHAT DOES HYALURONIC ACID DO FOR SKIN

On a daily basis, Hyaluronic Acid is constantly produced by cells and degraded by enzymes (called: hyaluronidases) that’s the natural life cycle of Hyaluronic Acid. From 25, the amount of Hyaluronic Acid starts to decrease due to an imbalance between its production that slows down with age and its degradation which accelerates.
When Hyaluronic Acid is faster degraded than produced, skin loses its natural capacity to keep the water in. Skin lacks suppleness and dehydration lines appear. This is the first sign of premature aging.
Alongside this, UV exposure and pollution leads to oxidative stress, a bomb for existing Hyaluronic Acid. But that’s not all: other external factors from our lifestyle as nutrition, tabaco, stress, sleep deprivation can also be responsible for oxidative stress and accelerate Hyaluronic Acid loss.
Did you know?
In addition to its role of biological moisturizer in the epidermis, Hyaluronic Acid also contributes to sustain collagen production in the dermis. Both molecules are responsible of skin plumpness and suppleness. In the long term, when Hyaluronic Acid rate decreases in skin, collagen too.

Recently, it has been integrated in Elvive Hyaluron Moisture range for its wrapping and caring properties on the hair fiber to maintain a good hair quality and to boost suppleness and shininess.
L’Oréal Paris uses a biodegradable, biocompatible and biomimetic Hyaluronic Acid for the skin. It is formulated via a biotechnological processes using a lactic bacteria fermentation process. Naturally inspired, highly tolerable, its high standard quality makes it suitable for all skin types and tones.
L’Oréal Paris’ cosmetic products indicate presence of Hyaluronic Acid on their list of ingredients as Hyaluronic Acid, or Sodium Hyaluronate, or sodium Acetyl Hyaluronate.

It is really important to use different types of Hyaluronic Acid to have a complete action: on skin surface to fight against skin dehydration and deeper in skin to slow down wrinkles’ appearance.
L’Oréal Paris uses 3 different types of hyaluronic acid in its superior formulas: two pure Hyaluronic Acid types and one acetylated:
    HIGH MOLECULAR WEIGHT HYALURONIC ACID: the one that immediately replenish skin with moisture.
    Macro Hyaluronic Acid, (high molecular weight Hyaluronic Acid superior to 1000kDa) that has a high affinity with skin surface for immediate hydration and smoothing of fine lines coming from dehydration.

    MICRO MOLECULAR WEIGHT HYALURONIC ACID: the one that penetrates deeper to hydrate in depth.
    Micro Hyaluronic Acid (low molecular weight until 50 kDa) penetrates the epidermis and moisturizes skin in-depth. It helps to reduce skin roughness and boosts/stimulates skin’s natural production of Hyaluronic Acid.

    MICRO-EPIDERMIC HYALURONIC ACID: the one that replumps and protects collagen, another key plumping molecule.
    Micro-epidermic Hyaluronic Acid (very low molecular weight (25kDa)) has been proven to penetrate and deliver a complete anti-wrinkle by slowing down both Hyaluronic Acid and collagen degradation.

L’Oréal Paris is an expert in the formulation of Hyaluronic Acid in skincare. With several formulas adapted to specific targets, we have tested it in 7 clinical studies with a panel of 200 patients.
Did you know?
L’Oréal Paris Hyaluronic Acids are obtained from biotechnology. The process consists in using biofermentation of lactic bacteria feaded with cereal grown in the same geographical area. The acetylation of our micro epidermic Hyaluronic Acid is made from green science. Our Hyaluronic Acid are produced in France and in Switzerland.

Micro epidermic acid is a smart Hyaluronic Acid. This micro Hyaluronic Acid is tagged with a signature that cells put on molecules they produce by their own to protect them from degradation. By marking HA with this tag, the strategy is to enhance the life span of the molecule in the skin thus making it efficient for a longer period.
The micro epidermic Hyaluronic Acid that L’Oréal Paris has been tested and the study showed it was 13x long lasting in the skin.
Did you know?
It has been shown that micro Hyaluronic Acid used in filler injections boosts collagen synthesis, also responsible for plumpness and firmness of the skin.

It’s never too late or too early to start using a skincare with Hyaluronic Acid. Everyone needs moisture, it’s a universal need.
There is no limit to how often you can use Hyaluronic Acid on skin. All our Hyaluronic Acid are biocompatible and bioavailable for all skin type even sensitive ones. We recommend using it both morning and evening, before any other skincare. You can layer multiple products with Hyaluronic Acid in your routine such as serums, day and night creams. By increasing moisture, it will help other ingredients to better penetrate.

WHAT DOES HYALURONIC DO FOR HAIR?

The benefits of hyaluronic acid can be harnessed by any hair type as it can assist with many hair concerns – whether you’re dealing with dryness, damage or frizz. Introducing hyaluronic acid hair products to your regular routine can help to maintain hair health and assist in overall moisture retention. When applied to hair, hyaluronic acid helps to reduce porosity and lessen moisture loss. Porous hair tends to retain less water, so by locking in the moisture of hair follicles with hyaluronic acid, it can help to eliminate frizz and give your mane that extra volume. If you suffer from dry hair, hyaluronic acid can also help to moisturise dry and flaky areas on your scalp. Dry and frizzy hair typically see the most noticeable benefits, as does over-processed, damaged hair.

What are the differences between hyaluronic acid and retinol?

Hyaluronic acid is a naturally occurring molecule that lends skin plumpness, volume and bounce due to its ability to hold up to 1000x its weight in water. As we age, our skin’s water retention ability declines and incorporating topical HA into skincare can be a useful way to replenish hydration and plumpness. Retinol, on the other hand, is a powerful derivative of vitamin A, an unparalleled anti-ageing active. Retinol works by increasing the rate of cell turnover which helps to visibly renew the skin, smooth texture and reduce the appearance of wrinkles.

Can you use hyaluronic acid with retinol?

Yes, hyaluronic acid and retinol work excellently in tandem and have properties that complement one another, making this one of the most popular skincare combinations. The benefits of retinol are strengthened when accompanied by HA as it helps the skin to stay hydrated and works to counteract skin prone to irritation caused by retinol - especially in the early stages of introducing retinol into your skincare routine.

Should you use hyaluronic acid before or after retinol?

The answer to this question depends on whether or not you’re looking to amp up the potency of your retinol. As hyaluronic acid helps to hydrate the skin and the effects of retinol are amplified by moisture, applying your HA product before retinol will intensify its effects. If you’re new to retinol or have sensitive skin, you’ll want to swap that order. For a milder result, apply retinol to clean, dry skin, and wait up to 30 mins before applying your hyaluronic acid step.

Can you use hyaluronic acid with retinol and niacinamide?

Niacinamide and hyaluronic acid pair well together and combined with retinol makes for an impressive trio of ingredients that can tackle several skin concerns. Whether these ingredients are combined into one, multi-tasking product or layered in a regime, their hydrating and brightening properties are unmatched. As dry and flaky skin is a common side effect of regular retinol use, niacinamide and HA make for an excellent accompaniment to your retinol application.
