☀️ What Does SPF PA++++ Mean? A Simple Guide to Sunscreen Labels
Ever stare at a sunscreen bottle and feel like you’re reading a secret code? Between SPF numbers, PA ratings, and broad spectrum claims, it can feel like you need a decoder ring just to protect your skin. Let’s break it all down in cozy, Bee Well style!
☀️ SPF: Your Sunburn Shield
SPF stands for Sun Protection Factor, and it measures how well a product protects your skin from UVB rays — the rays that cause sunburns.
SPF 30 blocks about 97% of UVB rays
SPF 50 blocks about 98%
SPF 100 blocks about 99%
The higher the number, the more protection — but no SPF blocks 100% of UVB rays. And yes, you still need to reapply every 2 hours!
🌤️ PA++++: Your Anti-Aging Armor
PA is a rating system for UVA rays, which go deeper into the skin and cause premature aging, pigmentation, and can contribute to skin cancer.
PA+ = some UVA protection
PA++ = moderate
PA+++ = high
PA++++ = the highest UVA protection
If you’re protecting against dark spots, fine lines, or sun-induced melasma, look for PA++++ on your label.
Bonus tip: This rating is more common in K-beauty or Japanese sunscreens, which is one reason I love them in my spa retail area! I just ordered and will have some available for purchase soon!
“Broad Spectrum” — What It Really Means
In the U.S., if a sunscreen is labeled broad spectrum, it means it’s passed a test showing protection from both UVA and UVB rays. It's the FDA's way of confirming it does a little of everything — but it doesn’t guarantee strong UVA protection like PA++++ does.
So ideally? You want broad spectrum + SPF 30+ + PA++++ for full sun defense.
Other Terms You Might See
Mineral / Physical Sunscreen: Uses zinc oxide or titanium dioxide to block rays. Great for sensitive skin.
Chemical Sunscreen: Absorbs UV rays with ingredients like avobenzone or octinoxate. Tends to feel lighter on the skin.
Water-Resistant: Still reapply after swimming or sweating! It doesn’t mean waterproof.
Tinted SPF: Adds a touch of color and often better for preventing pigmentation because the iron oxides protect against visible light too.
