India, June 21 -- When shopping for sunscreen, people generally concentrate on their SPF. But the PA value should also be considered, especially during summer days that have excessive heat when the intensity of the sun's UV rays is at its highest point. For those who are confused between PA+++ or PA++++, knowing the difference could guide you.

What Does the PA Rating Mean?

The abbreviation "PA" indicates Protection Grade of UVA, which is a Japanese grading scale used to evaluate the effectiveness of sunscreen in blocking out UVA rays. While UVB rays result in sunburns, UVA rays cause more serious damage since they penetrate deeper into the skin, causing premature aging and pigmentation.
