At least every two hours, more if you are in and out of the water. Also this depends on your skin type. Fair skinned should be even more often. Cover up at mid-day and stay out of the sun! You could try P20 - apply an hour before going into the sun and it lasts all day, through swimming!How many times a day one should put sun cream?
Here are two websites with advice about choosing and applying sunscreen. How often you need to put it on will depend what you are doing and what kind of sunscreen it is. Probably every three to four hours if you are not swimming or sweating alot. If you are swimming put more on after you get out of the water.
