SPF (Sun Protection Factor) is a measure of how well a product protects against UVB rays, which cause sunburn and skin damage.

SPF: How to Choose and Use Sunscreen Correctly

SPF 30 means you receive 30 times less UVB radiation compared to unprotected skin. UVA rays penetrate deeper, causing photoaging and DNA damage. That’s why it’s essential to choose products labeled "broad spectrum" or "UVA + UVB".

How to Choose a Sunscreen:

– For daily city use: SPF 30–50, lightweight texture, optionally tinted
– For outdoor activities, beach, or mountains: SPF 50+, water-resistant
– For sensitive skin: Physical (mineral) filters, hypoallergenic formulas

Usage Tips:

1. Apply 15–20 minutes before going outside

2. Reapply every 2 hours and after swimming or sweating

3. Don’t skip sunscreen even on cloudy days or indoors near windows
