It will interest you to know that a lot of things that many people know about sunscreen are myths. How much do you know about sunscreen? Check out these myths and facts about sunscreen before you head out into the sun.1. Sunscreen causes cancerThis myth originated from the belief that oxybenzone is capable of causing health problems. However, there is no published study that demonstrates the toxic effects of oxybenzone. It’s important to keep in mind that all the ingredients used in making sunscreens are FDA-approved including oxybenzone, which means there is no cause for alarm.2. I don’t need to wear sunscreen because I have dark skinMany people assume that sunscreen is unnecessary because they have dark skin but this could be nothing further from the truth. The sun is still able to damage dark skin but the problem is that the effects are harder to spot. Sunscreen is important for all skin types and can help prevent skin cancer as well as slow down aging caused by the sun.3. Sunscreen prevents my body from absorbing vitamin DVitamin D is an essential nutrient that promotes health growth, supports a healthy immune system and can help stave off a number of diseases. The sun’s radiation is a source of vitamin D (alongside other foods), thus making exposure to the sun important. However, it is false that sunscreen prevents the absorption of vitamin D as some UV rays will still reach you no matter the sunscreen you use.4. My sunscreen is waterproof, so I don’t need to reapply it after swimmingWhile it’s not uncommon to see sunscreen products labelled as water-resistant or sweat-resistant, such labels are actually an overstatement of what sunscreen can do. There’s no such thing as waterproof sunscreen or any of such similar tags. You will need to still reapply sunscreen even if it is touted as waterproof as water lessens the layer of UV protection that it offers.5. My sunscreen is SPF 50 so I don’t need to apply it oftenSPF sunscreen only provides protection for an average of 2 hours regardless the numbers associated with it. The numbers associated with it doesn’t mean the number of hours of protection it offers but how much protection you’re getting while it lasts.6. The SPF in my makeup is enough to protect my faceWhile it’s true that makeup does provide some level of protection from the sun, it is often not enough to completely protect your skin from the sun. Makeup is not a replacement for sunscreen but can serve as an additional layer of protection.7. I don’t need sunscreen if it’s cloudy or coldAnother common myth is that you don’t need sunscreen when it’s winter or cloudy. UV rays are present all the time during the day and clouds cannot protect from them because they’re merely water vapor. The same is true of colder days.8. I don’t need to wear sunscreen if I plan to stay indoorsThe sun emits two types of rays: ultraviolet A (UVA) and ultraviolet B (UVB). You are protected from UVA when you’re indoors but UVB can still reach your skin while you’re indoors, especially if you plan to spend your time close to a window. Hence the need to wear sunscreen at all times.9. As long as I don’t burn, it’s healthy to get a little colorSome people believe that it’s okay to tan their skin but the process is essentially your cells dying. There is no such thing as safe tan as any kind of exposure to the sun without sunscreen can cause accumulated damage to your skin cells. Wrap-upIf you can’t stay out of the sun, sunscreen can help protect your skin from UV damage and sunburn. Instructions on how to use each sunscreen may vary, so be sure to follow the instructions on the packaging.What do you think? Did you fall for any of these myths? Tell us in the comments below.
