What you must remember :
- Hyaluronic acid is one of the major components of skin tissue.
- Hyaluronic acid is a hygroscopic molecule that can be loaded with water (up to 1000 times its weight!)
- It provides the skin with hydration, elasticity and tone.
- It reduces the first signs of skin aging (slackening, dryness and loss of volume).
- It protects the skin from external aggressions (UV, pollution, bacteria, etc.) by strengthening the skin barrier.
What is hyaluronic acid?
Hyaluronic acid is a large molecule composed of a glucuronic acid and an amino sugar,N-Acetylglucosamine .
Hyaluronic acid is an essential molecule in supporting the skin. Naturally present in the epidermis and dermis, it acts like a “water sponge”. A molecule of hyaluronic acid can hold up to 1000 times its weight in water. Hyaluronic acid is a perfectly natural substance. Thanks to its humectant power, it ensures hydration and allows the skin to maintain its radiance and softness.
What are the benefits of hyaluronic acid?
Hyaluronic acid and skin
Hyaluronic acid, a compound with many benefits , is one of the main constituents of the skin, which is the largest organ of the human body. The skin surface is in direct interface with the external environment and provides protection for the body. In order to face multiple daily attacks (thermal, UV radiation and infectious agents), the skin forms a real physical and chemical barrier.
Hyaluronic acid is a high molecular weight molecule that can absorb water in order to maintain optimal hydration of the skin and contribute to its vitality. Likewise, it participates in tissue regeneration and promotes healing, while strengthening this natural barrier that the skin forms.
Hyaluronic acid and hair
Hyaluronic acid doesn't just hydrate the skin!
Hyaluronic acid also has moisturizing properties for hair. Indeed, just like the skin, the hair can become dehydrated due to a diet poor in vitamins or even repeated attacks by the application of heat. These factors lead to degradation of the hair fiber and visible loss of material. Hyaluronic acid will strengthen the hair structure and bring suppleness and shine to your hair.
The anti-aging benefits of hyaluronic acid
With age, hyaluronic acid production decreases and the skin ages naturally. The skin will then dry out, lose volume and become slack. This inevitable physiological process of cellular aging can be accelerated by external factors such as UV radiation, air pollution, tobacco, alcohol or poor diet.
Hyaluronic acid is a reference molecule in the fight against aging. Indeed, its powerful humectant power allows it to fill the spaces in the extracellular matrix, which constitutes the framework of the tissues, and to slip between the collagen fibers and elastin. This is how it gives firmness, elasticity and freshness to the skin. However, with age, hyaluronic acid production decreases and the skin ages naturally. The skin will then dry out, lose volume and become slack.
The different hyaluronic acid treatments
Depending on its use, hyaluronic acid comes in different forms: creams, lotions and serums. These treatments, thanks to the recognized virtues of hyaluronic acid, bring the promise of hydrated, plump and smoother skin.
The use of a high molecular weight hyaluronic acid molecule in a facial treatment will have a rather protective and firming action on the skin. This large molecule will not be able to penetrate the skin barrier. The hyaluronic acid on the surface will prevent water from evaporating, bring freshness to the skin and protect it from external aggressions.
Hyaluronic acid injections also help treat skin problems (acne, skin spots, blackheads, etc.) and restore radiance to the complexion. However, these injections can cause bruising and swelling on the face, where the skin is thin and sensitive.
Some studies suggest that taking hyaluronic acid orally can restore radiance to the skin through a deep action. Oral intake allows you to considerably increase the stocks naturally present in the body. If hyaluronic acid is recognized for its numerous anti-aging and hydrating benefits , oral intake goes further. It will not only repair and strengthen tissues in depth, but also protect the body from oxidative stress. The skin will then light up from the inside.
Indication and dosage of hyaluronic acid
It is found in many supplements in the form of powder, tablets or capsules.
Taking hyaluronic acid is contraindicated in children under 12 years old and pregnant and breastfeeding women. It is also common in people suffering from acute tissue inflammation, autoimmune disease or cancer. If you are undergoing medical treatment, it is important to seek advice from your doctor before supplementing and to take hyaluronic acid away from treatment if this is authorized.
