Collagen is the largest and most important endogenous protein for the skin. It makes up a third of the total protein content of our body and, in addition to the skin, keeps teeth, bones, muscles, joints and all connective tissues strong and healthy. What's more: collagen is responsible for 60% of all factors that regulate the moisture content of the skin. The protein is therefore crucial for maintaining the functionality, elasticity and firmness of the skin. Figuratively speaking, it is the glue that holds the body together. The problem: The body's own collagen production decreases over the course of life and this leads to increasingly sagging, wrinkled skin. The good news is that you can get to the root of the problem and make up for this deficiency fairly quickly with collagen-based skin care. In fact, it can even minimize existing signs of aging and greatly mitigate future negative changes. Because collagen can penetrate the epidermis from the outside, moisturize it sustainably and restore the elasticity of the skin. Provided that it is skin-identical collagen. One that has a comparable molecular structure to the body's own collagen and can therefore be absorbed particularly well by the skin. This collagen is found exclusively in the skin, intestines and bone marrow of animals. There is nothing to gloss over: All other collagens cannot effectively counteract the causes of skin aging. You should know that.
