National Sunscreen Day is on Thursday, May 27, 2027, and it falls on May 27 every year. It arrives just as summer starts, a timely reminder to protect your skin from the sun. Sunscreen works best as part of a routine that also includes shade and protective clothing.
When Is National Sunscreen Day?
It’s always May 27. It’s an unofficial health awareness day, often promoted by dermatologists and pharmacies.
Who Started National Sunscreen Day?
No founder or start year has been documented.
Background: what sunscreen does
Broad-spectrum sunscreens with SPF 15 or higher help lower the risk of skin cancer and early skin aging, the FDA says. They work best alongside other sun protection.
“Broad spectrum” means a product protects against both UVA and UVB rays. Labels can also claim water resistance for 40 or 80 minutes, but the FDA notes “there’s no such thing as ‘waterproof’ sunscreen.”
How to Use Sunscreen Correctly
The American Academy of Dermatology (AAD) recommends a sunscreen that is SPF 30 or higher, broad spectrum and water resistant.
- Apply early: put it on before you go outside. It takes about 15 minutes to absorb and protect you.
- Use enough: most adults need about 1 ounce, roughly a shot glass, to cover exposed skin, plus about a teaspoon for the face.
- Don’t miss spots: cover the neck, ears, tops of the feet and legs, and use an SPF 30 lip balm.
- Reapply: every two hours, and right after swimming or sweating.
- Use it on cloudy days: UV rays reach your skin even when it’s overcast or cool.
How to Celebrate National Sunscreen Day
- Check expiration dates: the FDA says a sunscreen without a date should be considered expired three years after purchase.
- Stock up: keep sunscreen in your bag, car and beach tote.
- Seek shade at midday: the sun’s rays are most intense between 10 a.m. and 2 p.m., the FDA notes.
- Cover up: wear a wide-brimmed hat, sunglasses and lightweight long sleeves.
- Protect babies: keep infants under 6 months out of the sun, and ask a doctor before using sunscreen on them.
- Make it a habit: add sunscreen to your morning routine, like brushing your teeth.
- Book a skin check: ask a doctor about any spot that’s new, changing or unusual.
Frequently Asked Questions
Is SPF 100 much better than SPF 30?
Higher SPF blocks slightly more UVB, but no sunscreen blocks everything. Applying enough and reapplying matters more than a very high number.
Can I use last year’s sunscreen?
Yes, if it’s within its expiration date and has been stored properly. Toss it if it’s past date, or if you don’t know its age.
Do I need sunscreen if I have darker skin?
Yes. People of all skin tones can get sun damage and skin cancer, so the AAD recommends sunscreen for everyone.
