Hyaluronic acid: LActive's No. 3 active ingredient for optimum hydration

Hyaluronic acid, my No. 3 active ingredient, is a powerful humectant that attracts and retains moisture, making it an ingredient of choice in cosmetics. Naturally present in our bodies, it plays a crucial role in skin hydration and suppleness.

What is hyaluronic acid ?

Hyaluronic acid is a polysaccharide, a molecule made up of long chains of carbohydrates, found naturally in the human body, particularly in the dermis of the skin, cartilage and joints. It is capable of retaining up to 1000 times its weight in water, making it an excellent moisturising agent and a major asset in skincare.

A little history ...

Discovered in 1934 by the Japanese scientist Dr Karl Meyer, hyaluronic acid was first isolated from bull's eye. Its use has evolved over the decades, from a medical treatment to a leading skincare ingredient. Since the 1990s, it has been widely incorporated into cosmetic products, and is now an essential ingredient in anti-ageing and moisturising treatments.

Where does it come from?

Hyaluronic acid is extracted from a variety of sources, including :

  • Animal sources : traditionally, hyaluronic acid was extracted from the crest of a cockerel or other animal tissue.
  • Plant and biosynthetic sources : today, many brands favour extraction methods from plant sources such as wheat and corn, or use bacterial fermentation to produce pure hyaluronic acid, guaranteeing optimal quality and high skin tolerance.

The properties of hyaluronic acid on the skin

Hyaluronic acid is appreciated for three main properties : its moisturising power, its regenerative effect and its protective action. These characteristics make it a must-have in skincare, promoting a more youthful, radiant appearance.

Powerful moisturiser

Hyaluronic acid is an exceptional humectant, capable of retaining up to 1,000 times its weight in water ! It attracts water from the environment and holds it in the upper layers of the epidermis, helping to prevent dehydration. Studies show that hyaluronic acid can maintain skin hydration by forming a light film that helps reduce water evaporation. This keeps skin supple, smooth and visibly younger-looking. As skin ages, it naturally loses hyaluronic acid, which contributes to dryness and the appearance of wrinkles. By using products containing this active ingredient, you can compensate for this loss and restore your skin's radiance.

Regenerative

Hyaluronic acid promotes cell regeneration and improves skin texture. It stimulates the production of collagen and elastin, two proteins essential for maintaining the skin's elasticity and firmness. By promoting cell regeneration, hyaluronic acid helps to reduce the appearance of fine lines and wrinkles. Studies have shown that topical application of hyaluronic acid improves skin texture and can reduce the signs of ageing. Regular use of hyaluronic acid helps to maintain youthful, dynamic skin, while promoting an even complexion.

Protector

Hyaluronic acid also acts as a skin protector. It forms a barrier that protects the skin from external aggressors, such as pollution, UV rays and climatic variations. By reinforcing the skin barrier, hyaluronic acid helps to prevent dehydration and maintain the skin's integrity. This protective action is particularly beneficial for skin that is sensitive or prone to irritation. By incorporating this active ingredient into your skincare routine, you create a first line of defence against harmful environmental factors, contributing to healthier, more protected skin.

Secondary properties of hyaluronic acid in cosmetics

Improved elasticity

By deeply hydrating the skin, hyaluronic acid helps to improve skin's elasticity and firmness, reducing the appearance of fine lines and wrinkles.

Reduced signs of ageing

Hyaluronic acid can help to fill in fine lines and wrinkles, giving skin a smoother, younger appearance.

Soothing effect

Thanks to its moisturising properties, it can help to soothe and calm irritated or sensitive skin.
