Your Ultimate Defense Against UV Damage from the Sun
Sun protection is important both to protect from skin cancer and to prevent premature skin-aging. Approximately 80% of skin’s aging comes from the sun. The best way to combat these detrimental sun effects is to implement a broad spectrum sunscreen into your daily skincare routine!
Why do you need a broad-spectrum sunscreen?
The sun emits UVA and UVB rays. Both can cause burns and premature aging—but UVA rays are mostly responsible for aging and UVB rays are mostly responsible for skin cancer and sunburns. A broad-spectrum sunscreen which covers both rays would be the most effective for the best results.
How do I choose the best sunscreen for me—what is SPF?
SPF stands for sun protection factor:
- SPF 15 blocks 93% of rays
- SPF 30 blocks 97% of rays
- SPF 50 blocks 98% of rays
Dermatologists recommend staying between SPF 30 and SPF 50 for sufficient sun protection.
How do I use sunscreen effectively?
It is best to apply sunscreen on the whole body—face, neck, and body—30 minutes prior to sun exposure to make sure the product absorbs into the skin. Especially on a hot summer day, you should reapply sunscreen every two hours as it naturally breaks down over time. On a day that is especially hot or you’re swimming, you should apply sunscreen more frequently.
The American Cancer Society also recommends wearing protective clothing such as a hat and sunglasses, staying in the shade when possible, and avoiding tanning beds.
It’s important to remember that sunscreen should be used every day, not just for hot summer days or days spent outside. The sun’s rays can penetrate through windows, and blue light from electronics may also contribute to skin damage—so SPF should still be worn on cloudy or rainy days, and even when you are staying indoors.
