Where does acid come from?
hyaluronic?
Hyaluronic acid is a complex molecule and one of the major natural constituents of living tissues, particularly cartilage. It is synthesized mainly by fibroblasts and keratinocytes (skin cells) in the different layers of the skin (dermis and epidermis). In fact, the skin is the main reservoir of hyaluronic acid since it contains 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 producing it continuously.
Overall, hyaluronic acid helps maintain the structure of the skin's layers. Thanks to its viscoelastic properties and its ability to capture and retain water, it gives the skin bounce and supports it. It is therefore essential to the biological activity of the skin and is one of the key elements in the quality of the dermis and epidermis.
With age, the quantity and quality of hyaluronic acid in our skin decreases. 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 (its size), 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 which regulates perspiration (and therefore water loss).
- Hyaluronic acid retains water on the surface of the skin and acts as a water “reservoir”.
- Hyaluronic acid protects the skin from external aggressions which 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 allowing the stimulation of fibroblasts (support cells which ensure the suppleness of the skin) 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 care varies depending on:
- A treatment with high molecular weight hyaluronic acid helps retain water on the surface of the epidermis (the upper 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 captures up to 1,000 times its weight in water, which gives it an extremely significant and unmatched hydrating power. It is even nicknamed the "molecular sponge".
For what skin types?
All skin types need hyaluronic acid, but especially dehydrated skin and mature skin.
For example, a
serum that contains hyaluronic acid will be suitable for both oily and dry skin, water and hydration being a need common to all skin types and an excellent preventive active ingredient against skin aging.
The use of facial care products containing hyaluronic acid is essential for those who wish to maintain well-hydrated, plumped skin and to preserve the youthfulness of the skin.
