The connective tissue of our skin consists partly of the protein fibers collagen and elastin. Collagen gives support to our skin and elastin gives it its elasticity. Special cells, called fibroblasts, produce these proteins on an assembly line and thus keep our skin firm and elastic. This is an ongoing process of reproduction that the body regulates itself until about our mid-twenties. As we age, cell activity decreases and the skin loses its elasticity, making it flabby and lines/wrinkles appear.

Collagen is one of the most important body proteins in our body. It is located in the second layer of the skin called the Dermis or dermis. This layer gives the skin firmness and consists of a dense construction of connective tissue. Collagen can be seen as the main structuring protein of our skin.

Elastin is a protein that provides elasticity to the skin. It forms a network of fibers and, like collagen, is located in the second layer of that skin called the Dermis or corium skin. The elastin fibers make up only 5 to 10% of the total number of skin fibers, but they are essential to ensure the elastic properties of the skin.

The main function of fibroblasts is the production of collagen fibres, the non-stretchable fibers that provide strength to our tissues. In addition, they also make other components of the ground substance, or extracellular matrix, in the connective tissue. Connective tissue consists mainly of fibroblasts and can be found under the epidermis, among other things. In addition, fibroblasts also play a role in wound healing. They can transform into myofibroblasts, which close the wound. They are responsible for scar tissue, which consists mainly of collagen fibers.
