The Difference Between PA+++ and PA++++

You’re doing everything right. You check the SPF, you apply enough sunscreen and then you see it: PA+++ or PA++++.
Suddenly, confidence turns into confusion.

The Big Idea

Those plus signs aren’t decoration. They measure how well your sunscreen protects against UVA rays the rays responsible for pigmentation, wrinkles, and long-term skin damage.

The Story

For years, sunscreen conversations focused only on sunburn. But people noticed something strange: even without burning, skin still aged, darkened, and developed spots.

That’s when UVA entered the chat.

The Science

UVA rays penetrate deeper into the skin and can pass through clouds and even glass. PA ratings indicate the strength of protection against these rays.

PA+++ offers good UVA protection.
PA++++ offers very high, longer-lasting UVA protection.

• If you’re dealing with pigmentation, melasma, or using active ingredients like retinol or acids, UVA protection matters just as much as SPF.

The Modern Translation

SPF protects your skin today.
PA protects your skin over time.

Resolution

If you’re investing in skincare, choosing PA++++ helps protect that investment quietly, consistently, and for the long term.
