Proteins, mainly collagen , are fundamental building blocks of human skin. Collagen homeostasis is a natural process, in which our body produces collagen and breaks it down into peptides. Collagen is produced by fibroblasts and broken down by enzymes, namely matrix metalloproteinases (MMP) . When there is a good balance between production and collagen degradation, the extracellular matrix generates a beautiful, firm skin. When more collagen is broken down than produced, the firmness diminishes and wrinkles appear. Therefore, it is both important to stimulate your collagen production and to inhibit collagen fragmentation .
