I do wear SP15 every day as well - thought I would LOVE to find a product with SP30 that was non-oily and didn't make me sweat. So many SP products seem to make me feel like my skin can't breath.
Here's another great sunscreen I adore for cycling in high altitudes and never breaks me out, or gives me that chalky look. You can read some reviews on Amazon and there are several versions, including one for drier skin.
