Protect Your Skin Every Day: All About Sunscreen, SPF, and the Difference Between Chemical and Physical Sunscreens
Why Should You Apply Sunscreen Every Day? UV rays can cause skin aging, dark spots, and even skin cancer. Even on cloudy days or indoors, ultraviolet rays can still harm your skin. That’s why applying sunscreen daily—no matter the weather—is a simple but essential habit for healthy skin. Which SPF Should You Choose? SPF 30 or higher: The American Academy of Dermatology recommends SPF 30 or above. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. For daily use: SPF 30–50 and PA++ or higher is enough. For outdoor activities or travel: SPF 50+ and PA+++ or higher is recommended. Waterproof formulas: Choose these for sports or swimming.
