The main way of preserving your skin's youth is simple: hydration! This should be a fundamental part of your skin care routine to fight signs of aging: your skin will stay beautiful and youthful. A hydrating cream will plump up lines and your first wrinkles and prevent them from reappearing. Go for skin care products with a formula rich in antioxidants, which form a real protective shield against the free radicals behind skin aging, and in anti aging ingredients. Try pro-xylane, which will retighten tissues, hyaluronic acid, which will boost hydration and plump up wrinkles, and LHA, which will smooth out the skin. And, don't forget to protect yourself from the sun; whether in summer or winter, at the beach, in the mountains or even in the city; to avoid the harmful effects of UV rays, which accelerate skin aging and encourage the appearance of wrinkles, lines and dark spots. There's no need to start using night cream at 20, but an eye contour product may be useful. The first wrinkles tend to make their appearance in this fragile area of the face, which requires very specific treatment.
