If you’re aiming for your best skin, sunscreen is non-negotiable. But how do you choose the right one when the label is full of confusing terms like SPF, PA+++, or blue light protection?
Let’s break it down so you can protect your skin smarter — and get closer to your healthiest, best skin yet.
SPF – Sun Protection Factor
SPF measures protection against UVB rays, which cause sunburn and increase your risk of skin cancer.
- SPF 30 blocks about 97% of UVB rays
- SPF 50 blocks about 98%
To maintain your skin, apply sunscreen above 30 SPF generously and reapply every 2–3 hours — especially outdoors.
PA Rating – UVA Protection
PA indicates protection against UVA rays, which penetrate deeper and lead to tanning, pigmentation, and ageing.
- PA+++ or PA++++ = High to very high UVA protection
If you want to prevent pigmentation and preserve your best skin tone, always check the PA rating.
Blue Light Protection
Screens aren’t harmless — phones, laptops, and even indoor lights emit blue light, which can lead to pigmentation and dullness over time.
Look for sunscreens that mention:
- “Blue Light Protection” or “HEV Light Filter”
- Ingredients like iron oxides or antioxidants
This is especially important if you’re indoors often but still want to maintain bright, even-toned, best skin.
Apply sunscreen every morning — whether it’s sunny, cloudy, or you’re just sitting at your desk.
