The Ultimate Guide to SPF: What Dermatologists Want You to Know

Blog

SPF is non-negotiable, but many people still get it wrong. Whether it’s using too little, not reapplying, or picking the wrong formula, small mistakes can leave your skin vulnerable.

SPF Numbers Explained

SPF (Sun Protection Factor) indicates how well a sunscreen protects against UVB rays. SPF
30 blocks around 97% of UVB rays, while SPF 50 blocks 98%. The key difference is how often
you need to reapply, not how invincible you are.

Chemical vs. Mineral Sunscreen

– **Chemical Sunscreens** absorb UV rays and convert them to heat. They’re lighter and
blend easily but can irritate sensitive skin.
– **Mineral Sunscreens** use zinc oxide or titanium dioxide to reflect rays. They’re great
for sensitive skin and start working immediately.

Application Tips

– Use a nickel-sized amount for your face and a shot-glass amount for your body.
– Don’t skip your lips—use an SPF lip balm.
– Reapply every 2 hours, especially after swimming or sweating.

SPF Myths Busted

– Darker skin tones need SPF too. Melanin offers some protection, but not enough.
– SPF in makeup is not enough on its own. Always layer with a standalone sunscreen.

Extra Protection

Pair SPF with antioxidants like vitamin C and E to enhance protection against free radicals.

Final Word

SPF is your first line of defense against aging and skin cancer. Use it daily, rain or shine, to keep your skin healthy long-term.
