As summer approaches, National Sunscreen Day, on May 27, reminds everyone to protect their skin from the sun's ultraviolet (UV) rays. Sunburns are painful, and too much sun exposure raises the risk of skin damage. Wearing sunscreen, along with hats, sunglasses and shade, is one of the simplest ways to stay safe while enjoying the outdoors.
History of National Sunscreen Day
People have protected their skin from the sun for thousands of years. Ancient Egyptians used ingredients like rice bran and jasmine, and ancient Greeks used olive oil.
Modern sunscreen developed in the 20th century. In the 1930s, chemist Franz Greiter developed an early sun cream after getting sunburned while climbing a mountain. During World War II, pharmacist Benjamin Green created a product to protect soldiers in the Pacific, which later contributed to commercial sunscreens.
In 1974, Greiter popularized the Sun Protection Factor (SPF) rating. The U.S. Food and Drug Administration regulates sunscreen as an over-the-counter drug. Who created National Sunscreen Day is not documented.
Why National Sunscreen Day Matters
Sunscreen helps prevent sunburn and reduces the risk of skin damage from UV rays.
The day reminds people to build sun protection into their daily routine, especially before summer.
Sun safety is important for all skin tones. Dermatology organizations recommend broad-spectrum sunscreen, protective clothing and shade during peak sun hours.
Protecting skin is not only for beach days. UV exposure adds up during everyday activities, such as walking, driving, gardening and playing sports. Making sunscreen part of a morning routine, like brushing teeth, is one of the easiest habits to build. Many moisturizers and lip balms now include SPF, making daily protection simpler.
How to Celebrate National Sunscreen Day
- Apply sunscreen: use broad-spectrum SPF 30 or higher and reapply every two hours (or after swimming).
- Wear a hat: choose a wide-brimmed hat.
- Seek shade: especially between 10 a.m. and 4 p.m.
- Wear sunglasses: protect eyes from UV rays.
- Check the date: replace expired sunscreen.
Celebrating at Work, School and Home
At work, employers with outdoor workers can provide sunscreen and shade breaks; office teams can share sun safety tips before summer. In classrooms, students can learn about UV rays, test UV-sensitive beads under different sunscreens, and make sun safety posters. At home, families can stock up on sunscreen, check expiration dates, and make sunscreen part of the daily routine before outdoor play. Ask a doctor about sun protection for babies under six months.
