Even after frequent swimming throughout the day P20 retains the same protection category as before entering the water which is unique for a sun protection product. In fact, P20 has been categorised as "Very Water Resistant"2, the highest classification available. P20 offers broad spectrum photostable UV protection covering both UVA and UVB rays and retains its effectiveness even after and during exposure to the sun. P20 is proven to work for up to 10 hours in the sun. For ease of use P20's lightweight consistency ensures an even coverage. Once a day application means a little goes a long way, making P20 more economical than other sun care products that need to be re-applied regularly during the day. P20 is absorbed rapidly leaving a non-greasy skin, so there are none of the messy white streaks common with cream-based products.
