Sunscreen is your #1 anti-aging and skin-saving tool. But not all SPFs are created equal.
What SPF Numbers Mean
SPF (Sun Protection Factor) indicates how well a product protects against UVB rays. SPF 30 blocks about 97% and SPF 50 blocks 98%. No sunscreen offers 100% protection, so reapplication is key—especially after sweating or swimming.
Chemical vs. Mineral Sunscreens
- Chemical: Absorb UV rays. Lightweight but may irritate sensitive skin.
- Mineral: Use zinc oxide or titanium dioxide to reflect rays. Often better for sensitive skin and children.
Don’t Rely on Makeup SPF
SPF in makeup is not enough protection. You’d need to apply several layers to reach effective coverage. Use a standalone sunscreen under your foundation or BB cream.
