Chemicals, chemicals...  Keeping them off your skin and out of the water is a goal of ours here at lollybrolly.  Wear sunscreen if you must, or if you are in the sun for extended periods of time.  Lollybrollys are made of paper, they are not actual sunscreen, so it's similar in protection to wearing a hat.  Use your own discretion about the chemicals you do and do not put on your skin.  Here at lollybrolly, we hope you will choose the most planet-friendly types available, while your lollybrolly keeps you cool..!
