La Roche-Posay Anthelios UV Air Fluid SPF50+ is a sunscreen that uses UVAIR technology to provide the skin with very high protection against the effects of UVA and UVB radiation as well as long-wave UVA. The formula contains hyaluronic acid to keep the skin hydrated and niacinamide, which regulates sebum production and has an antioxidant effect for 16 hours. The moisturising sunscreen is characterised by a light, invisible texture that leaves the skin feeling fresh and allowing it to breathe. It is also quickly absorbed without being greasy or leaving any residue.
