riA returns back to the fundamental concept of “what is actually good for your skin” and eliminates as much as possible everything else. A concept obvious in principle, but rarely applied, riA (the word ‘Air’ in reverse) was developed to be as unobtrusive to our skin as the Air that surrounds us, but an effective answer to natural anti-ageing skin care. The key to riA’s effectiveness is the use of a unique "lamellar liquid crystal structure", one of the few skin moisturising serums in the world to do so. The surface of human skin includes a lamellar structure.

The lamellae work to protect and keep skin hydrated, however, everyday stress and environmental factors cause the lamellae to break down. When applied, riA products form a lamellar liquid crystal structure (a barrier), which quickly repairs then protects damaged skin. The sister brand to Japanese natural skin care range retaW, riA Tokyo is a three step natural anti-ageing process. In keeping with Niven & Joshua philosophy, riA products contain no Ethanol, Artificial Colouring, Synthetic Perfumes, Synthetic Surfactants, Mineral Oil, Parabens and the pump-dispensers are antibacterial for the added safety of your skin.
