In the US, most people are familiar with the Sun Protection Factor (SPF) - your sunscreen or cosmetic’s ability to shield your skin from UVB rays. The SPF number on your sunscreen indicates how long it takes for your skin to burn in the sunlight.
that’s not exact measurement because everyone’s skin and The climate of the place of residence are different . However, it does tell you that it will take x times longer for sun to burn your skin
PA stands for Protection Grade of UVA, so PA+ ratings measure a product’s ability to block UVA rays.You’ll spot PA ratings on a variety of sunscreens, healthy makeup, and skin care products.
Developed in Japan, the PA rating system was adapted from the Persistent Pigment Darkening (PPD) method.
These conversions go as follow:
If a product’s PPD = 2 to 4, PA = PA+
If a product’s PPD = 4 to 8, PA = PA++
If a product’s PPD = 8 to 16, PA = PA+++
If a product’s PPD = 16 or higher, PA = PA++++
PA+ offers some UVA protection. PA++ provides moderate UVA protection. PA+++ delivers good UVA protection while PA++++ provides extremely high UVA protection.
It’s important to note that not all countries use the same ratings as PPD is not standardized
