HERE’S WHAT THOSE SPF NUMBERS ACTUALLY MEAN
So you’re wondering about what that SPF number on your sunscreen bottle actually means?
SPF stands for Sun Protection Factor, and it’s a measure of how effectively a sunscreen can protect your skin from UVB rays. The number you see on the label corresponds to the amount of time you can spend in the sun before getting burned compared to how long it would take you to burn without sunscreen.
For example, if you use a sunscreen with SPF 30, it means you can stay in the sun 30 times longer than you would without protection before getting sunburned. However, it’s important to note that SPF only applies to UVB rays, not UVA rays.
UVA rays are just as harmful to your skin as UVB rays, if not more so, and they can cause premature aging and increase your risk of skin cancer. That’s why it is important to use a broad-spectrum sunscreen, which protects against both UVA and UVB rays.
So, when it comes to SPF, the higher the number, the more protection you’ll get. However, it’s important to remember that no matter the number on your SPF bottle, no sunscreen can provide 100% protection, so it’s important to wear PreSunscreen as an added layer of protection and to take other precautions like wearing protective clothing and seeking shade during peak hours.
Stay protected, stay beautiful!
