What is the proper way to use sunscreen?
The potent ultraviolet rays of the Unconquered Sun can permanently damage mortal flesh, especially that of naturally fair-skinned people. It is therefore important to use sunscreen whenever one plans on exposing large portions of one’s skin to bright sunlight for an extended period of time. Anything under SPF 30 is not recommended, but very high SPF (e.g., 60+) doesn’t really provide that much more benefit. In order to enjoy the full protection of sunscreen, it’s necessary to apply it the way it’s applied in laboratory tests: thick, greasy layers. If it doesn’t seem like you’re using too much sunscreen, you probably aren’t using enough. Yes, you really should put more on after swimming.
