get a long sleeve or stronger sunscreen. The SPF number is a multiple of the safe amount of minutes you can be in the sun unprotected. Depending on where you are that might only be a minute, meaning SPF 30 is a half hour of exposure before you have to reapply.
It is not the number of minutes. It is a factor of time that would be safe without protection.
