Everything On SPF
What does SPF stand for?
SPF stands for sun protection factor. Sunscreens are classified by an SPF number which refers to their ability to deflect UVB rays.
How does SPF rating work?
The SPF rating is calculated by comparing the amount of time needed to burn sunscreen-protected skin vs. unprotected skin. For example, if wearing SPF 30, it takes 30 times longer to burn than not wearing any sunscreen at all.
What is broad-spectrum SPF?
A broad-spectrum sunscreen protects against both UVA and UVB rays. UVA rays penetrate the skin’s thickest layer and can lead to premature skin aging, while UVB rays burn the superficial layers of your skin and play a key role in the development of skin cancer. Using a broad-spectrum SPF 30 or higher protects against both types of skin damage.
The Best Way to SPF Every Day
Studies show that most people only apply 25-50% of the recommended amount of sunscreen. We want to make sure your skin is well-protected—when applying SPF to your body, use one ounce, which is about the amount that would fill a shot glass. When applying SPF to your face, use the size of a nickel, which is around 1/3 of a teaspoon. Apply your SPF at least 15 minutes before any kind of sun exposure, even if you’re just sitting near windows, or if it’s cloudy outside. Sunscreen should be applied at least every 2 hours to maintain full SPF protection, no matter your favorite formula. If you’re swimming, or even sweating, you should apply again after the water-resistant time, which is 40 minutes to 80 minutes, depending on the product. Finally, don’t forget to reapply after towel drying!
What is Blue Light?
Blue light (also known as high energy visible light, or HEV) is the strong light that emits from the screens of cell phones, computers, tablets, and TVs, as well as fluorescent and LED lighting.
Why do I need Blue Light defense?
Considering we spend up to 12 hours a day in front of digital screens, we’re often getting a lot more exposure to blue light than we are to UV. Plus, research indicates that blue light can reach deeper into the skin than UVA and UVB rays, taking a toll on the health of our skin.
