When choosing a sunscreen, you often see terms like SPF 50 and PA++++ — but what do they actually mean?
Many people assume a higher SPF is enough, but that’s only part of the story.
To truly protect your skin from tanning, pigmentation, and aging, you need to understand both SPF and PA rating.
What is SPF?
SPF (Sun Protection Factor) measures protection against UVB rays.
UVB rays are responsible for:
- Sunburn
- Skin damage
- DNA damage
How SPF Works
- SPF 30 → blocks ~97% UVB
- SPF 50 → blocks ~98% UVB
No sunscreen blocks 100% UV rays.
What is PA Rating?
PA rating measures protection against UVA rays.
UVA rays are responsible for:
- Tanning
- Pigmentation
- Premature aging
PA Levels Explained
- PA+ → Basic protection
- PA++ → Moderate protection
- PA+++ → High protection
- PA++++ → Very high protection

What Matters More?
👉 Both are equally important

If you only focus on SPF and ignore PA, your skin can still tan and age faster.
