With the natural aging process, the hyaluronic acid content in the skin also decreases from around the age of 25. At around 60 years of age, the body only has around 10% of the initial level of hyaluronic acid. Since hyaluronic acid molecules are the main component of the filling material lying between the skin cells, the decrease in hyaluronic acid means a loss of volume - wrinkles appear. This loss of volume can be counteracted with hyaluronic³ products.
