Hyaluronic acid has been widely used by the cosmetic industry for its beauty benefits. But what is hyaluronic acid?
In the fight both of the cosmetic industry itself against aging and in beauty itself, the discovery of hyaluronic acid has been an authentic and true anti- wrinkle revolution, being widely used today by many cosmetic companies.
Hyaluronic acid is a molecule that we can find in different tissues of all special animals, including even the human body itself. It is especially concentrated in the epidermis, the vitreous humor of the eyes, and in the synovial fluid that lubricates the joints. However, over time these molecules decrease in quantity, deteriorating their function.
What does hyaluronic acid consist of?
Hyaluronic acid consists of a substance, specifically a carbohydrate, that we find completely and completely naturally in a wide variety of tissues and organs throughout our body.
For example, we can find hyaluronic acid in tissues such as the epidermis, cartilage, connective tissue, the eyes or in synovial fluid, to name just a few examples.
As we will see in the section dedicated to the benefits and properties that hyaluronic acid offers us for the skin, its main capacity is to attract and retain water, which is why it is essential for these tissues to be kept in optimal conditions.
What benefits does hyaluronic acid bring to the skin?
When the amount of hyaluronic acid decreases, something that usually occurs during the natural aging process of our body, the skin tends to lose hydration, which translates into a loss of elasticity and firmness.
As a result, the skin becomes more flaccid, at which point certain wrinkles and other signs that are so characteristic of aging begin to appear.
But the decrease in hyaluronic acid is not only evident on the skin. Internally, although we obviously can’t see it, the amount of this polysaccharide is also reduced in the joints, causing the cartilage to become stiffer and break more easily. It is, for example, a common cause of pain when moving the joints, as a result of rubbing between the bones.
For all these reasons, the use of hyaluronic acid is common when it comes to reducing wrinkles in certain areas of the face, even replacing the also popular botulinum toxin (Botox).
Its main uses in beauty
Precisely because of its great capacity to attract and retain water, and above all because of the results obtained in its surgical application through injections, hyaluronic acid has become very famous, and can even be applied topically through facial treatments and creams.
The topical application tends to be less aggressive than the first, since the effect produced by the injections are visible more quickly. It is an invasive method, so the topical application tends to be much more natural.
However, the application of this acid by intradermal injection has been shown to be capable of stimulating and activating fibroblasts, which are a type of cell found in connective tissue and that tend to produce anti-aging substances in the skin. Even in elderly people, stimulating the formation of collagen.
In addition, its effects are much more positive, since hyaluronic acid in its topical form stimulates the production of elastin and collagen, so the skin is intensely hydrated.
For example, hyaluronic acid is commonly used in cosmetic clinics as a treatment to eliminate wrinkles located in the area around the nose and the sides of the mouth, the contour of the lips and in the corners of the lips, between the eyebrows, in the forehead area and those known as crow’s feet.
But this acid is not only used in cosmetics as a way to reduce wrinkles. Did you know that it is also used in medicine? For example, it is often used in the medical treatment of degenerative joint diseases, such as osteoarthritis, through infiltrations in order to reduce and relieve pain and help in the regeneration of cartilage.
While, in dentistry, hyaluronic acid is used to regenerate the gums and improve the natural healing of the oral mucosa.
