What does collagen and hyaluronic acid do for your skin?
Do you know what they are and why they are used in cosmetics and skincare products?
Eating fruits and vegetables helps produce hyaluronic acid and collagen, which are vital for healthy skin. Collagen ensures that our skin retains its elasticity so it is essential for anti-aging, while hyaluronic acid provides long-lasting hydration for our skin and helps it repair quickly.
It is important to know that collagen is one of the essential elements to ensure the flexibility and elasticity of our tissues. Moreover, it is naturally present in the body.
As for hyaluronic acid, this molecule has superpowers and is essential for skin beauty.
Read on to understand what and why these are so important to combat skin aging.

What does collagen and hyaluronic acid do for your skin? Introduction
Let’s go into more detail on collagen and hyaluronic acid below.
What is collagen?
To give you a simplistic idea of the definition of collagen, we can compare it to glue. It is a hard, insoluble, and fibrous protein massively present in the body.
Our skin is composed of 75% collagen, making it the main structural element in the body.
What is the purpose of collagen?
It is essential to know that this substance maintains and gives the body its shape.
It forms a kind of “framework” that defines the body’s structure. Moreover, it has a protective and regenerating power.
Collagen ensures the robustness and elasticity of the skin and muscles. It also maintains the health of tissues, ligaments, tendons, nails, hair, and bones.
In the dermis, collagen also plays a role in replacing and restoring dead skin cells.
There are two types of collagen:
- The endogenous collagen is natural collagen synthesized by the body
- Exogenous collagen is synthetic and comes from an external source (marine or animal).
How do we notice that our collagen levels are dropping?
It is essential to know that as the years go by, but especially at the age of 35 or so, the level of collagen in the body naturally decreases, which is reflected in the first signs of aging of the skin.
Indeed, the first wrinkles appear, the skin becomes dry, and the first joint pains appear. The end of menopause corresponds to a significant loss of collagen synthesis in women.
The origins of animal collagen
When it comes to animal collagen, it can come from cows, pigs, sheep, or fish skins.
To use collagen of animal origin, it is necessary to perform skin tests to avoid the risk of allergies.
Collagen intake is justified to reduce wrinkles and fine lines of the face and mask scars.
Revitalization of the skin
Keep in mind that collagen creams are not very effective. Indeed, the collagen molecules that compose them are too big to penetrate the skin.
The only benefit that may be obtained will probably be due to the moisturizing effects of the cosmetic products. But this does not directly increase collagen levels.
Where to find natural collagen?
An adapted and balanced diet is necessary to maintain the firmness and elasticity of the skin.
By adopting a rich, varied and healthy diet, you can boost collagen production.
Vitamin deficiencies such as B1, B2, B3, B5, B12, C, E, and potassium, zinc, magnesium, calcium, iron, phosphorus, manganese, and selenium decrease collagen in the body.
To remedy these various deficiencies, you must change your diet and opt for foods rich in these vitamins, minerals, and other trace elements.
The essential fatty acids, linoleic acid, and alpha-linolenic acid also play an important role in collagen production.
What is hyaluronic acid?
Let’s move on to an explanation of hyaluronic acid.
What does hyaluronic acid do?
Hyaluronic acid is a carbohydrate molecule naturally present in our body. It was discovered in 1934 by a German biochemist who discovered that this molecule is present in the vitreous humor of our eyes.
Later, some studies showed that this molecule participates in the development and viscosity of cells.
It was not until the 1970s that eye surgery was the first to benefit from the fruits of hyaluronic acid research with the appearance of a biomedical product.
Hyaluronic acid would have the property of lubricating the connective tissues of the joints and the skin. It, therefore, plays a vital role in the health of the body.
This component is also present in internal fluids and connective tissue. But the skin remains the organ in which it is most concentrated. It represents 50% of the total level of hyaluronic acid in the body.
Hyaluronic acid has incredible hydration capabilities
One of its properties is to provide long-lasting moisture to the skin. Indeed, hyaluronic acid acts as a water retention medium so that the skin can absorb it.
The hyaluronic acid molecule can store up to 1000 times its weight in water.
Like the collagen molecule, the hyaluronic acid molecule cannot penetrate the epidermis due to its size.
Therefore, it acts from the skin’s surface by retaining water to diffuse it as needed so the skin remains perfectly hydrated.
Hyaluronic acid has anti-aging benefits
Over the years, the level of hyaluronic acid decreases, causing a gradual dryness of the skin. Did you know that babies have such soft skin because of the high level of hyaluronic acid in their skin?
The loss of hyaluronic acid is also characterized by less supple skin. Moreover, following this, the first fine lines and wrinkles appear.
A contribution of hyaluronic acid will restore hydration, firm the skin, and smooth wrinkles and fine lines. The skin will appear firmer and more toned.
Hyaluronic acid increases the health and protection of the skin
Our skin is the first barrier against external aggressions. In fact, when it becomes dry, its surface is more vulnerable to damage and infection.
The hydrating capacities of hyaluronic acid reinforce the protective barrier of the skin and intervene in its repair thanks to its anti-inflammatory properties.
Hyaluronic acid also has an antioxidant power that helps fight against UV damage.
Where to find hyaluronic acid naturally?
Hyaluronic acid is found in the connective tissue of animals. Poultry, eaten cooked or used in a broth, is an excellent source of hyaluronic acid. In general, all meats contain a high level of these.
It is also possible to supplement your hyaluronic acid intake by eating fruits and vegetables. To do this, you must choose foods rich in vitamin C and magnesium to synthesize the acid.

What does collagen and hyaluronic acid do for your skin? Conclusion
Whether it is collagen or hyaluronic acid, we have seen that these molecules are naturally present in our bodies.
However, over time, it is possible to lose these two elements. Consequently, your skin will lose its suppleness and elasticity.
An adapted and balanced diet is necessary to supply the body with enough collagen and hyaluronic acid.
