What does SPF and PA mean?

"SPF" stands for “Sun Protection Factor”. The value demonstrates the effectiveness of protection against UV-B, as well as the degree of protection against UV-B when nothing is applied on skin. For example, SPF 25 means that the UV protection product is 25 times more effective on guarding against skin redness from the sun than when nothing is applied on skin.

PA stands for “Protection Grade of UV-A”. PA+ signifies the product as having “protection efficacy” with PA ++ and PA+++ indicating strong protection efficacies. In general, the higher the SPF value, the higher the PA value.
