Why can you not find low level like SPF 4 or 8 anymore? Everything is 15 to 50 or more. I would like to have something to turn 4 hours of yard work into a half hour to an hour of exposure. I don’t need to turn it into 5 minutes of exposure.
try a natural sunscreen like coconut oil, olive or avocado oil baby oil with iodine is not recommended but used years ago.
