What Is PA in Sunscreen and Why PA++++ Should Be Your Non-Negotiable

We all know SPF is the skincare superhero when it comes to sunburn protection but here’s a little secret: SPF only tells half the story. If you’re not checking the PA rating on your sunscreen, you might be leaving your skin wide open to the kind of damage that leads to fine lines, pigmentation, and collagen breakdown.

So let’s clear it up: What is PA in sunscreen, and why does PA++++ sunscreen deserve a permanent place in your skincare routine?

First, What Exactly Is PA?

PA stands for Protection Grade of UVA. It’s a system that measures how well a sunscreen blocks UVA rays, which are the sneaky ones responsible for premature aging, sun-induced pigmentation, and long-term skin damage.

While SPF shields you from UVB rays (the ones that burn), the PA rating is all about protection from UVA, the rays that age your skin silently and steadily.

Here’s what the scale looks like:

• PA+ = Some UVA protection

• PA++ = Moderate protection

• PA+++ = High protection

• PA++++ = Extremely high UVA protection

In short, the more pluses, the better. And PA++++ sunscreen? That’s the gold standard.

Why UVA Protection Should Be a Daily Priority

UVA rays don’t take a break. They’re present every single day, rain or shine and they can pass through clouds and even windows. That means even when you're indoors or commuting in a car, your skin can still be exposed to UVA damage.

And here’s the catch: UVA rays don’t burn your skin like UVB. They work slowly, damaging collagen, deepening pigmentation, and accelerating signs of aging over time.

So, what is PA in sunscreen, practically speaking? It’s the part that does the heavy lifting when it comes to long-term skin health, the kind of protection that keeps your skin looking firm, even-toned, and glowing years from now.

PA vs. SPF: Know the Difference

A lot of us stop at SPF and that’s where the mistake happens. Think of SPF and PA as partners in protection. Here’s a quick breakdown:

So if you’re using an  SPF 50 sunscreen  without  PA++++, you’re only covering half the damage. A PA++++ sunscreen with SPF 50+  is the full package.

Who Should Be Using PA++++ Sunscreen? (Spoiler: Everyone)

If you:

• Struggle with dark spots or melasma

• Are trying to prevent fine lines
  

• Have sensitive skin or redness

• Want to wear sunscreen under makeup

• Are simply serious about skin longevity
  

…then you absolutely need to be using a PA++++ sunscreen every single day.

And honestly, even if none of these apply, the damage UVA rays do over time is reason enough to make the switch.

Mineral or Chemical Sunscreen? Can Both Offer PA++++?

Yes! Whether you prefer mineral sunscreens (with zinc oxide or titanium dioxide) or chemical filters (like Uvinul, Tinosorb, or avobenzone), both can offer PA++++ protection. The choice depends on your skin type and finish preference.

• Mineral PA++++ Sunscreen: Great for sensitive or acne-prone skin. Sits on top of the skin and reflects UV rays.

• Chemical PA++++ Sunscreen: Lightweight, blends easily, often invisible on skin. Great for daily wear and layering under makeup.

Just remember if you’re picking up a product with the PA++++ sunscreen label, it’s working to protect your skin from deep-level UVA damage, no matter the filter type.

Don’t Settle for Less Than PA++++

Still wondering what is PA in sunscreen and why it matters? Think of it this way:

SPF protects you from the burn.
PA++++ protects you from the consequences.

And if you’re committed to glow now and healthy skin later, there’s really no debate. Make sure your sunscreen says PA++++ and use it every single day, year-round.
