Why is hyaluronic acid good for the skin?

Where does hyaluronic acid come from?

Hyaluronic acid is a complex molecule and one of the major natural constituents of living tissues, particularly cartilage. It is synthesized primarily by fibroblasts and keratinocytes (skin cells) in the different layers of the skin (the dermis and epidermis). Indeed, the skin is the main reservoir of hyaluronic acid, containing half of the body's total mass. And it is the dermis that is richest in it. Present in all living beings, hyaluronic acid can now be reconstituted from substances of natural origin, such as wheat.

What is the role of hyaluronic acid?

As you will have understood, hyaluronic acid is a molecule naturally present in the skin and our body is responsible for continuously producing it. Overall, hyaluronic acid helps maintain the structure of the skin's layers. Thanks to its viscoelastic capacities and its ability to capture and retain water, it gives bounce to the skin and helps support it. It is therefore essential to the biological activity of the skin and is one of the key elements of the quality of the dermis and epidermis. With age, the quantity and quality of hyaluronic acid contained in our skin decrease. Result: wrinkles appear, the skin becomes thinner and more easily marked, it loses its firmness and the oval of the face tends to sag.

What are the superpowers of hyaluronic acid?

Depending on its molecular weight, hyaluronic acid will have different actions at different levels of the skin:

• Maintain the skin's natural hydration: Hyaluronic acid forms a non-occlusive film that regulates perspiration (and therefore water loss). It also retains water on the skin's surface and acts as a water "reservoir." It also protects the skin from external aggressions that can alter the natural lipid barrier.
• Strengthen the skin's natural defenses and the wound healing process.
• Improve the biomechanical properties and firmness of the skin by increasing the amount of dermal hyaluronic acid and stimulating its production.
• Rejuvenate the dermis from the inside, by stimulating fibroblasts (support cells that ensure the skin's suppleness) and thus the synthesis of collagen.

In cosmetic care, different sizes of hyaluronic acid are used and the action of the cream, serum or any other facial treatment varies depending on:

• A treatment with high-molecular-weight hyaluronic acid helps retain water on the surface of the epidermis (the top layer of the skin). A real asset for hydrating and plumping the skin while creating a protective barrier against daily aggressions, inflammation, and dehydration.
• A treatment containing low molecular weight hyaluronic acid treats the skin more deeply with a real action on wrinkles and firmness and therefore a visible anti-aging effect.

Did you know? Hyaluronic acid can absorb up to 1,000 times its weight in water, giving it extremely powerful and unparalleled hydrating properties. It's even been nicknamed the "molecular sponge."

For what skin types?

All skin types need hyaluronic acid, but dehydrated and mature skin especially needs it. For example, a serum containing hyaluronic acid will work equally well for oily and dry skin, as water and hydration are a need common to all skin types and an excellent preventative ingredient against skin aging. Using facial skincare products containing hyaluronic acid is essential for those who want to maintain well-hydrated, plumped skin and preserve the skin's youthfulness.
