Scientists found | 29 types of collagen in the human body |. Type I is the most abundant in the skin (80%)
| As the French Health and Medical Research Institute explains |, collagen is a protein that the body is not able to assimilate in this form. When ingested, it is broken down into amino acids. These amino acids can then be used by the body to build proteins, i.e. collagen or other proteins
Therefore creams with collagen are a pure marketing invention. Skin application will in no way generate the production of collagen
Collagen-based food supplements are made from animal collagen. Gelatin is obtained by subjecting the bones and skin of animals, most often farmed cattle or pigs. By transforming the gelatin a little further, we obtain a hydrolyzate of collagen or collagen peptides. Marine collagen, for its part, comes from shrimp shells or the skins, scales and bones of fish such as tuna, cod or salmon. There is no such thing as plant collagen
There are several studies showing a positive effect on the skin. However, the vast majority of these studies were commissioned by cosmetic laboratories, are limited by their number of participants and by the lack of monitoring of long-term effects. European Food Safety Authority bans health claims about | skin elasticity | and | maintenance of joints |
Our lifestyle is the first factor that affects our ability to produce collagen. Diet, smoking, alcohol, UVs and non-practice of physical exercise are the main culprits
We can improve our ability to synthesize collagen with a diet rich in vitamin C, zinc, glycine and proline. Cabbage and spirulina are superfoods
