The hyaluronic acid content in our body is not the same throughout life. Natural aging processes lead to a continuous degradation of the valuable active ingredient. This gradual decline begins at the age of 25 and then progresses inexorably. At around the age of 60, only 10 percent of the original amount of hyaluronic acid is still present in the body. Connective tissue and skin lose volume and flabbiness, facial structures sink and wrinkles form.
