Collagen is at the heart of our skin's youth and vitality. Naturally present in our bodies, it ensures firmness, suppleness and resistance. Over time, however, production slows down. Fortunately, simple steps and carefully chosen supplements can help support this valuable protein. Here is what you need to know.

What is collagen?

Collagen is a structural protein produced by our cells. It is omnipresent in the human body, and can be found in bones, tendons, muscles, ligaments, and especially in the skin. In fact, around 75% of our dermis is made up of collagen.

 

What is the purpose of collagen?

The word "collagen" comes from the Greek kolla, meaning "glue." That shows how important it is! Without it, our tissues would lose their cohesion. In the skin, it acts like an invisible net, uniting the different skin layers.

This protein prevents skin slackening, facilitats hydration and promotes cell regeneration. As a result, the skin is firmer, more supple and more luminous. Collagen is therefore an essential pillar in preserving the skin's youthful appearance.

What is the best collagen?

The "best" collagen depends on several factors: its source, bioavailability, form (powder, liquid, capsule), and of course, your personal goals. What you need to prioritize is hydrolyzed collagen (also known as collagen peptides), as it is more easily assimilated by the body.

Collagen Type I is the most abundant in the body, particularly in the skin. Supplements containing it are therefore often recommended for aesthetic purposes. This is complemented by synergistic active ingredients such as vitamin C, which stimulates its natural synthesis.

Marine or bovine collagen: which to choose?

Marine collagen is extracted from fish skin and bones. It is recognized for its high bioavailability, i.e., its ability to be efficiently absorbed by the body. Lighter than its bovine counterpart, it quickly penetrates the bloodstream, making it a preferred choice for anti-aging treatments.

Bovine collagen, on the other hand, comes mainly from beef connective tissue. It is often richer in Type I and III collagen, two valuable forms for skin, hair and nails.

 

Why take collagen?

Starting at the age of 30, our bodies produce 1% less collagen every year. What causes this? Cellular aging, oxidative stress, UV rays, pollution... All of these factors slow down the natural production of this protein. Therefore, it is important to take care of your skin and give it the supplements it needs.

What are the signs of collagen deficiency?

Collagen deficiency manifests itself in several ways:

• LooLoose, less elastic skin;
• The formation of deep wrinkles, especially on the forehead and around the mouth;
• Brittle nails and dull hair;
• The onset of joint pain;
• Recovery time becomes longer after an injury.

What are the benefits of collagen for the skin?

The benefits of collagen for the skin are easily visible and measurable. Here are the main improvements you will notice:

• A noticeable improvement in your skin's elasticity;
• A significant reduction in wrinkle depth;
• Better hydration;
• Your skin's texture becomes smoother and more uniform;.
• In particular, it has a visible “plumping” effect on your facial skin;

What is the best collagen after 50?

After age 50, it is advisable to choose hydrolyzed marine collagen enriched with antioxidants and vitamin C. At this age, the skin has lost much of its ability to regenerate on its own, and a consistent routine combining diet, topical skincare, and supplementation sential.

Vitamins and minerals play an important role in your daily life no matter what your age. Find out more about their role in our article.

• When out in the sun, always use a sunscreen with SPF 30 minimum, every day, even in winter.

Which foods are rich in collagen?

Collagen can be found in many of the foods you eat every day, and they all have a very specific role to play.

Some foods are naturally rich in collagen:

• Bone broth
• Fish skin
• Natural gelatins

Other foods promote collagen production:

• Citrus fruits, kiwis, strawberries (vitamin C)
• Nuts, sunflower seeds (zinc)
• Dark green vegetables
• Animal and plant proteins

What is the most effective liquid collagen?

Liquid hydrolyzed marine collagen is often recommended for its rapid absorption. If you are looking for this type of marine collagen, we recommend choosing a formula with no added sugar, enriched with vitamin C, containing certified peptides, and containing no artificial colours or flavours. The liquid form allows for optimal bioavailability, provided it is taken on an empty stomach or separately from protein-rich meals.

Collagen and supplements: what are the differences?

Collagen can be found in:

• Dietary supplements (capsules, powders, liquids)
• Topical skincare treatments (creams, serums)

The two approaches are complementary. Skincare products nourish the skin's surface, while supplements act deep down, where collagen fibres are formed.

Taking collagen is an effective way to slow the signs of aging, strengthen skin from within and support connective tissue. Collagen, and especially marine collagen, is a true beauty and health ally. Your pharmacist can also advise you and guide you toward solutions tailored to your skin type.
