P20's unique formula is non-greasy, non-oily and fragrance free to provide the ultimate coverage, both in and out of the water, for up to 10 hours a day. Once a day application: P20 is designed to ensure one application a day is sufficient, keeping the time spent reapplying sun protection to a minimum.

In fact, P20 has been categorised as very water resistant, the highest classification available from Colipa guidelines for evaluating sun product water resistance. UVA and UVB protection, offering UVA and UVB protection through highly photostable filters, P20 retains its effectiveness even on extended exposure to the sun. Easy to use: The unique, formulation has a thin consistency, ensuring an even and economic coverage that absorbs rapidly.
