I am so excited to be able to scuba dive in warm waters again. I also need to step up my game with making sunscreen because we have been getting more requests as the heat comes on! A comment by a customer was shared with me over the weekend about how well our sunscreen stays on even when you sweat. I agree. I am very active from running to swimming, and I wear my sunscreen as well. Although I always tell people that ALL SUNSCREENS need to be applied when you are coming into contact with water (or sweat) - it's true that ours stay on better than many due to the oils we add.
