Do you use products that have a PA rating, like SPF does?


What is PA?

PA stands for protection grade of UVA (UVA light is caused by aging factors) system and is the Japanese measurement of sun protection, which is based on the Persistent Pigment Darkening (PPD) reaction reading at 2-4 hours of sun exposure.  PA is a protective level of strength to mark the three PA+, PA++ and PA+++.

PA+ provides some UVA protection with a factor of PPD 2-4. It protects sensitive skin against low to medium UV radiation.

PA++ provides moderate UVA protection with a factor of PPD 4-8. It offers better protection from UVA rays and can be used by people with normal skin exposed to medium UV radiation.

PA+++ provides good UVA protection with a factor of PPD > 8. It is the strongest grade of UVA protection now available. It is designed for normal skin under very strong or direct UV radiation.
