Skin care: what products contain collagen?
Collagen is a key element for healthy, youthful skin. It is responsible for skin firmness, elasticity and regeneration. That's why many skincare products incorporate collagen to improve skin quality. But in which foods or products can you find collagen?
On this page, we'll introduce you to the different sources of collagen and provide tips on how to incorporate it into your skincare routine. 
What is collagen?
Collagen is a structural protein essential to skin health. It accounts for almost 75% of our skin's composition, giving it structure and firmness. Collagen is produced naturally by our bodies, but production declines with age, leading to loss of elasticity and the appearance of fine lines and wrinkles.
Collagen is made up of long chains of amino acids wound in a triple helix. There are different types of collagen, but types I, II and III are the most abundant in the skin. Type I collagen is present in most connective tissues, including skin, bones and tendons. Type II collagen is found mainly in cartilage, while type III collagen is associated with supple skin and blood vessels.
As we age, collagen production declines, leading to reduced skin elasticity and the formation of fine lines and wrinkles. That's why adding collagen to your skincare routine can be beneficial for maintaining firm, youthful skin.
There are different sources of collagen used in skincare products, including marine collagen, bovine collagen and plant-derived collagen. Marine collagen is extracted from fish such as salmon, cod and trout, and is valued for its high bioavailability and similarity to human collagen. Bovine collagen is derived from bovine skin and bone, while plant collagen is obtained from vegetable sources such as algae.
It's important to choose quality products containing collagen from reliable sources. Collagen serums, creams and supplements are popular options for incorporating collagen into your skincare routine. These products can help stimulate collagen production, improve skin hydration, reduce the appearance of wrinkles and improve skin texture and radiance.
By using quality collagen-containing products and taking a holistic approach to skin care, you can support your body's natural collagen production and maintain healthy, smooth, radiant skin.
The different sources of collagen
The collagen found in the ingredients of cosmetic products can be derived from a variety of sources, the most important of which are listed below:
Animal collagen
- bovine collagen: extracted from the skin, bones and tendons of cattle;
- Fish collagen: derived from fish scales, skin and fins;
- pig collagen: derived from pig skin and bones.
Plant collagen
Although collagen of plant origin is not directly available, there are plant-based products that can stimulate the body's natural production of collagen, such as vitamin C-rich foods, green leafy vegetables and red fruits.
Synthetic collagen
Scientific advances have made it possible to create synthetic collagen peptides that can be used in certain skincare products to stimulate collagen production and improve skin appearance. 
How can you incorporate collagen into your skincare routine?
Food supplements containing collagen are available as powders, capsules or liquids. They can be added to your daily diet to boost collagen production in the body.
In addition, many skin care products, such as creams, serums and masks, contain collagen. These products can moisturize the skin, improve its elasticity and reduce the appearance of fine lines and wrinkles.
What's more, many foods are rich in nutrients that promote collagen production. Therefore, a balanced diet including foods rich in vitamin C, essential amino acids and antioxidants can help support collagen production in the body. Foods such as citrus fruits, berries, green leafy vegetables, nuts and seeds are beneficial for skin health.
