Skin aging starts at about 20-25 years of age.
However, the changes are not clearly visible or sharp, and they are called primary features of aging.
Skin aging largely depends on genetically inherent individual human properties, lifestyle, harmful habits, and other factors. Such habits as smoking, frequently enjoyed sunbathing, stress, deficient diet, lack of sleep and leisure leave their marks on the human skin. As years go by, the skin elasticity deteriorates, the skin becomes dry, its tone and resilience changes, and the quantity of the hyaluronic acid in skin goes down.
