Skin & Sunscreen
Does SPF protect against both UVA and UVB rays?
Not automatically. SPF measures protection against UVB, the rays that cause sunburn. UVA rays penetrate deeper, age skin faster, and pass through clouds and window glass. Check that a sunscreen's label explicitly mentions broad-spectrum or UVA protection before relying on it.
Do I need sunscreen on a cloudy day?
Yes. UVA rays pass through cloud cover and glass, so your skin is still exposed even when the sun isn't visibly out.
Should I reapply sunscreen to my hands during the day?
Yes. Hands are exposed constantly, and everyday activities like food prep, bathroom visits, or gardening wash sunscreen away. When in doubt, apply.
Which spots do people most often forget to apply sunscreen?
The nose, ears (top and lobes), scalp, the backs of the knees and legs, ankles, and gaps where clothing shifts against skin, like the collar, waistband, or sock line. Applying sunscreen before getting dressed helps close those gaps.
Eyes & Lips
Should I wear sunglasses on cloudy days?
Yes. UVA reaches you through clouds just as it does on a clear day, and sunglasses protect both your eyes and the thin, sun-exposed skin around them.
Can I put sunscreen on my eyelids?
No, sunscreen shouldn't go directly on the eyes or eyelids. Always read the product usage instructions before applying. Sunglasses are the better way to protect this delicate area, and a larger pair covers more of the surrounding skin too.
Do lips need sun protection?
Yes. Lips are skin and burn just like anywhere else. An SPF-rated lip balm covers this commonly forgotten spot.
Clothing & UPF
What does the UPF rating on clothing mean?
UPF (Ultraviolet Protection Factor) measures how much UV radiation passes through a fabric. UPF 50 means roughly 1 in 50 UV rays gets through; UPF 40+ is considered good, and UPF 50+ excellent.
Should I wear UPF clothing in high UV areas?
Yes. UPF-rated shirts, hats, and cover-ups block substantially more UV than regular fabric. Combined with sunscreen, sunglasses, and SPF lip balm, this gives the most complete coverage.
What should I do right after swimming?
Swimming and sweat reduce how well sunscreen works, so dry off and reapply after a swim, then put on a shirt. A non-white fabric blocks more UV than white.
UV Index, Timing & Travel
Why do I burn faster on holiday than at home?
The UV index tends to be much higher near the equator and at higher altitude than in temperate climates, and daily habits don't always adjust for it. Water and sand also reflect UV back onto your skin, adding to the exposure.
How do I know the UV index for today?
Check a UV index app, website, or smartwatch. Knowing the day's number helps you decide when extra sunscreen, shade, or covering up is worth it.
What if there's no shade where I want to sit?
Prioritize shade over convenience. Bring an umbrella or move to a shaded spot rather than settling for none, especially around midday when UV is strongest.
