Why and how to take a collagen treatment?

Collagen, an abundant protein in the human body, is often considered the key element ensuring the strength and elasticity of tissues. Over time, collagen production declines with age , leading to various signs of aging, both aesthetically and health-wise. This is where the collagen treatment comes in. In this article, we will explore why such a cleanse can be beneficial and how to optimally integrate it into your routine. (2)

What is collagen?

Collagen constitutes 30% of the proteins present in the human body . It is found in many tissues, such as joints, bones, skin, teeth and blood vessels. As a structural protein, it provides support to tissues. It is involved in the elasticity, resistance and firmness of the skin .

There are ten types of collagen. But the one that is particularly found is type I collagen , which is most present in the human body . It constitutes approximately 90% of collagen. It is mainly found in ligaments, teeth, tendons, bones and skin. It gives stability and resistance to the body's connective tissues. It is essential for maintaining the firmness and structure of the skin by helping to prevent sagging skin and wrinkles. (2)(8)


Collagen decline with age

Collagen production naturally decreases from the age of 25 years, about 1.5% per year. This reduction increases with age and its production can be reduced by half at age 60. Fortunately, there are natural ways to boost collagen production in your body. This will allow you to maintain luminous skin and healthy joints. (3)

The progressive decrease in collagen synthesis results in the appearance of fine lines and wrinkles . You can fight the signs of premature aging by including collagen in your skincare routine. (3)

The same goes for hair and nails because their appearance will no longer have the same shine. Concerning physical health, joint pain will appear because the bones will no longer have the same flexibility. In itself, collagen helps maintain a healthy body. (3)

The different sources of collagen

Animal collagen:

  • Most common source, extracted from skins, bones or cartilage of animals (cattle, pigs, fish). (2)
  • Marine collagen, from fish, is particularly appreciated for its high bioavailability.

Marine collagen (1):

  • Rich in type I collagen, the most abundant in the human body.
  • Considered a source of high quality collagen. It helps improve the appearance of the skin and fight signs of skin aging .
  • Marine collagen type II is also known for its benefits for joints.
  • Contains essentials such as glycine, proline and hydroxyproline, which are necessary for the synthesis of collagen in the body.
  • Requires transformation by hydrolysis to facilitate better digestion.
  • The marine collagen treatment is very popular

Plant collagen:

  • Less common, extracted from algae or mushrooms.
  • Suitable for vegetarians and vegans.

Synthetic collagen:

  • Developed in the laboratory thanks to technological advances.
  • Still little used to this day.

Why take a collagen treatment?

In order to complement the action of the collagen produced by our cells, it may be interesting to take a food supplement containing collagen. This is crucial because several external factors, in addition to physiological aging, can decrease collagen synthesis:

  • Pollution
  • Excessive sun exposure
  • The harmful activity of free radicals
  • Tobacco and alcohol consumption
  • A diet that is too sweet

In order to fight against it, taking the supplement will:

  • Promote skin flexibility and joint mobility, especially when jointly linked to elastin
  • Preserve the skin's water content in collaboration with hyaluronic acid
  • Delay the appearance of markers of skin aging, such as sagging skin, wrinkles and small fine lines (such as expression lines and crow's feet).
  • Strengthen the tissues
  • Reduce cellulite
  • Prevent the appearance of stretch marks,
  • Help with cellular regeneration and wound healing
  • Reduce joint pain
  • Contribute to the improvement of digestive disorders

How to do a collagen treatment?

  • Collagen supplementation

There are several types of supplementation so you can choose the one that suits you best. The choice of collagen will depend on your needs and preferences. It is important to note that hydrolyzed collagen is easier to digest and assimilate.

Powder: One of the most common and most economical forms. It can be diluted in a drink, however the taste is sometimes unpleasant.

Capsules: They are convenient to transport, the taste is neutral and the dosage is predefined.

Tablets: These are similar to softgels and capsules but may contain compression agents and additives.

  • Foods rich in collagen

Adopt a healthy diet rich in nutrients essential for collagen synthesis, such as vitamin C, zinc and amino acids. So you can incorporate citrus fruits, green vegetables, nuts, seeds and lean proteins like fish and poultry into your diet. (4)

What cosmetics should you choose during a collagen treatment?

You can purchase skin care products containing ingredients such as vitamin C, vitamin A (retinol), and collagen peptides , which can help boost its collagen production and maintain healthy skin. (5)

Choose anti-aging creams containing hydrolyzed collagen, which is more easily assimilated by the skin. Also favor natural and organic products to avoid irritation. (5)
