What is the PA value of sunscreen

The PA value of sunscreen refers to the protection ability of the sunscreen to UV UVA. UV UVA can enter the dermis of the skin, and it is irreversible for the skin to accumulate.

What is SPF value of sunscreen

SPF value of sunscreen refers to the sun protection factor of the sunscreen, that is, the sunscreen's ability to resist ultraviolet UVB. Generally, when looking at SPF value, it should be determined according to the minimum erythema dose of the skin, while the minimum erythema dose of the person is generally 20 minutes, that is to say, without any protective measures, at most 20 minutes in the sun will produce erythema. So when looking at SPF value, girls usually use SPF value * Minimum erythema dose. For example, SPF15 sunscreen can protect UVB for 15 * 20 = 300 minutes, and so on~
