Skin Sun Safety

Common Questions & Answers
Sun exposure can lead to sunburn, which damages blood vessels and contributes to premature skin aging, including wrinkles, dryness, discoloration, and a leathery texture. Excessive UV radiation also increases your risk of skin cancer.
Two types of sunscreens, chemical and mineral, are available, and they work differently. Mineral sunscreens form a barrier that blocks UV rays from entering the skin, whereas chemical sunscreens convert light to heat, which radiates away from the skin.
The American Academy of Dermatology Association recommends a sunscreen with SPF 30 or higher. Apply it everywhere that could face sun exposure. To protect your face, neck, arms, and legs, you’ll need around 1 ounce of sunscreen — or about as much as would fill a shot glass.
Reapply sunscreen every two hours, or more often if you sweat a lot or are going swimming. This also applies to sunscreens that are labeled “water-resistant,” which are only effective for 40 or 80 minutes, depending on the product.
Wear protective clothing, seek shade, and avoid excessive sun exposure between the hours of 10 a.m. and 4 p.m.
