Riemann P20 Sun Filter 100ml SPF15 shields your skin from UVA/UVB rays for up to ten hours, so you stay protected all day long. Quick drying and extremely water resistant, it helps you to tan safely, without being greasy or sticky. You can spend more time enjoying the sun and less time worrying about topping up your sun cream. Directions of Use: Apply and allow to dry for 15 minutes before sun exposure. Avoid contact with eyes. Pat dry rather than rubbing your skin after swimming, as this will remove the product. If your skin has been rubbed or soap has been used, reapply.
