Question: what is the difference between suntan lotion and sunblock?
Answer: The terms 'sun lotions' and 'sunscreens' are used interchangeably to describe many of them. 'Suntan lotion' is sometimes used to refer to substances designed to accelerate tanning with little or no sun protection factor. Some people use the term 'sunblock' to refer to sunscreens that reflect rather than absorb UV rays.
