Hydrabio Hyalu+ serum is a highly concentrated serum that contains 2 types of hyaluronic acid that act on the causes of dehydration. The skin is intensely hydrated with a long-lasting effect, plump, fresh and bright. Wrinkles and fine lines are visibly reduced. How does it work? The influence of the external environment (air conditioning, pollution, UV radiation, sudden changes in temperature, cold, wind...) can dehydrate the skin and change its protective function, which weakens it and increases water loss. Natural aging processes also change the quantity and quality of hyaluronic acid in the skin over time. The skin becomes dehydrated and wrinkles and fine lines appear. Hydrabio Hyalu+ Serum is inspired by NAOS ​​innovative ecobiological approach. By understanding the biological dysfunction responsible for dehydration, it allows the skin to reactivate its natural hydration mechanisms and maintain the water necessary for its balance. The complementary action of precisely dosed active substances, including two types of hyaluronic acid and niacinamide, acts on the internal causes of dehydration and visible signs of aging with a long-lasting effect.
