P20 is proven to remain effective in the water, even after frequent swimming. P20 is Very Water Resistant and ranks in the highest class of Cosmetic Europe's water resistance classification system.
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.
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.
