There are many common ideas about sunscreen and its correct use. Unfortunately, there are also a lot of common misconceptions. Now, thanks to a medical expert, here are five truths that can put to rest the most common sunscreen myths:sunscreen

  1. A cloudy day means you don’t need sunscreen

While the clouds may provide shade and offer a reprieve from the heat of the sun, clouds do not completely block out the sun’s harmful UV rays. If it’s daytime, sunscreen is still necessary. In fact, according to a study done by the Skin Cancer Foundation, clouds only filter less than a quarter of the UV rays that can cause sunburn or skin cancer.

  1. Water filters UV rays

The truth is that UV rays from the sun absolutely penetrate the surface of the water. In fact, the water can reflect these harmful rays back onto the exposed parts of your skin. Sunscreen must be applied before entering the water and given time to dry, so the water doesn’t wash it off. A similar misconception is the idea that car windows block UV rays, which is also false.

  1. The higher the SPF, the longer the sunscreen lasts

The SPF number on sunscreen refers to its ability to block out UV radiation. All sunscreens should be reapplied every two hours because, after that time, sunscreens are dramatically less effective than when first applied.

  1. Skin cancer only affects exposed parts of the body

While it is true that UV radiation will only affect exposed parts of your skin, UV rays are not the only cause of skin cancer. Skin cancer can appear on any part of the body regardless of whether or not it gets little or no sun exposure. Always consult a physician about changes in skin tone, appearance, or texture.

  1. Sunscreen prevents skin cancer

Sunscreen is a great way to lower your risk of skin cancer, but using sunscreen does not ensure total immunity to this disease. Skin cancer can be caused by genetics and other factors. Furthermore, there is no sunscreen that blocks all forms of UV rays with 100% efficiency. Even the highest SPF applied every two hours will not prevent all UV rays from contact with the skin.
