UVA vs UVB — why the difference matters for your skin →
Frequently asked questions
Is a higher SPF always better?
Not really. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The jump in protection is small, but higher SPF products often cost more and can feel heavier on skin. What matters more is applying enough and reapplying every 2 hours.
What's the difference between mineral and chemical sunscreen?
Mineral sunscreens (zinc oxide, titanium dioxide) sit on top of the skin and reflect UV rays — better for sensitive skin. Chemical sunscreens absorb UV rays and convert them to heat — often lighter and easier to blend, but can irritate some skin types.
Do I need sunscreen on cloudy days or indoors near windows?
Yes. Up to 80% of UV rays pass through clouds, and UVA rays penetrate glass, meaning your skin is still exposed even indoors near a window or on an overcast day.
