Sun Safety and Sunscreen Basics
Prevent sunburn and lower skin cancer risk with simple habits.
UV and skin type
The UV index measures sunburn strength, and fair skin burns in minutes at high levels. Dark skin burns less easily but is still at risk.
Using sunscreen
Choose broad-spectrum SPF 30 or higher, apply about a teaspoon for the face and a shot glass for the body, and reapply every two hours.
Other protection
Wear hats and sunglasses, seek shade at midday and check moles regularly. See a doctor about changing spots.

Estimates assume no reapplication; reapply every two hours. Seek shade between 10am and 4pm and never use sunscreen to extend time in strong sun.
