Acide hyaluronique contre le vieillissement cutané.


Hyaluronic acid is a biomolecule that is naturally present in the skin, with remarkable hydrophilic properties. It acts like a molecular sponge, and is capable of holding up to 1,000 times its weight in water. When used in skincare, it prevents dehydration and the appearance of wrinkles. Plastic surgeons use it as an injection to reduce the signs of aging. Let’s take a closer look at one of the most effective anti-aging ingredients on the cosmetics market.

Hyaluronic acid maintains skin hydration.

Hyaluronic acid is naturally present in our bodies. For the most part, it is produced by fibroblasts in the skin, but our skin cells produce it too. Our skin contains 50% of the hyaluronic acid that is present in our bodies. Thanks to its amazing hydrophilic properties, it behaves like a sponge and holds water in our skin cells, maintaining skin hydration to leave it plumped.

As we age, our hyaluronic acid production slows and becomes lower quality. Every ten years, we lose around 6% of our hyaluronic acid. So, by age 50, our hyaluronic acid levels have halved. This drastic loss of hyaluronic acid leads to atrophy of the fatty pockets located under the skin, which causes the appearance of fine lines and wrinkles.

When injected, hyaluronic acid fills out wrinkles and smooths out the skin. However, hyaluronic acid-based skincare products are still an effective, and less invasive, way to fight the signs of aging.

Hyaluronic acid’s "anti-aging" benefits.

Hyaluronic acid helps to plump and hydrate the skin, making it a popular and effective ingredient to target wrinkles and reduce the signs of aging. It works in different ways according to its size:

  • High molecular weight hyaluronic acid:

    As you’ll have guessed from its name, this molecule is too big to penetrate the skin’s barrier, so it acts on the skin’s surface to form a protective layer against external irritants and dehydration. When used in a skincare product, this type of hyaluronic acid hydrates the surface layers of the skin to smooth out lines and wrinkles caused by expression or dehydration. It’s particularly effective at boosting your skin’s radiance.

  • Low molecular weight hyaluronic acid:

    At the opposite end of the spectrum, low molecular weight hyaluronic acid is a micro-molecule that deeply penetrates the skin. It is able to get under the layers of the epidermis, where it attracts and holds on to water to deeply hydrate and plump the surface of the skin. It boosts the skin’s natural fibroblast production, reduces the appearance of wrinkles and slows the signs of aging.

Our skincare products with hyaluronic acid are designed to reduce the appearance of fine lines and wrinkles.

Our plumping serum with 3% hyaluronic acid is an ultra-concentrated formula, designed for use morning and evening to smooth out wrinkles and tone the skin.

Our hydrating toner also contains aloe vera for total hydration. It regulates the skin’s pH after removing makeup/cleansing, and targets dehydration lines.

Our nourishing face cream is packed with lipid-replenishing and hydrating ingredients, and is 98% naturally-derived. It leaves your skin supple, and reduces the appearance of expression lines.
