Tried La Roche Posay SPF 55 one summer and I was pale as hell, not recommended at all. But I also want protection, that's why I'm considering something in the middle. I don't know where you live, but I live in Norway and at times here aren't that much sun here anyway. If I lived in Texas, California etc I would deff use something higher than SPF 15..You definiately need more than an SPF 15 on your face. The higher the SPF the better you are, in protecting yourself from sun damage.
