How to use: Squeeze out an appropriate amount of the sunscreen and evenly apply it to your face and other exposed skin areas before going outdoors. Make sure to cover all areas that need protection. Note: This is a final sale item, so it can't be returned. If you have extremely sensitive skin, it's a good idea to do a patch test first. Maintenance: Keep the sunscreen in a cool and dry place, away from direct sunlight. Don't let it freeze, as this might affect its effectiveness.
