SPF is a value that most individuals tend to overlook or over exaggerate. To get a better idea of why we shouldn’t overlook the SPF values, we need to know what SPF stands for and what it does. SPF or sun protection factor is a common attribute for choosing sunscreen. SPF is useful in protecting your skin against UVB rays but a wide spectrum sunscreen is the ideal choice. Additionally, it’s always ideal to make use of SPF15 or SPF30 since higher SPFs don’t really give more value.
Why is there a need to understand the purpose of SPF? There has been a huge leap on the occurrence of skin cancer in the community. In fact, there’s one in every five individuals who has skin cancer. What’s even more alarming is how melanoma, a very aggressive form of skin cancer, has begun to appear and raised skin cancer as the top four cancer on the list.
With these pieces of information in mind, it’s not surprising to be alarmed. It boils down to going under the sun for hours on end without putting some sunscreen on yourself. Some of the discolorations on your skin may have been caused by sun exposure while growing up. Worse, you might also happen to get skin cancer from constant exposure.
There are a lot of beliefs when it comes to using sunscreen and the SPF it comes. Here are some facts to get you around and better protect yourself from the harms of skin cancer.
People tend to rely on clouds for protection against the sun and would forego sunscreen. That’s actually a bad habit to follow. Clouds aren’t enough of a barrier to block off the rays and if you’re traveling via airplane, they may even cause more harm than good. Thus, you’ll want to lather a good amount of sunscreen even on overcast days.
One application of sunscreen is not enough to protect you for the entire day. Much like how creams or lotions work, sunscreen needs to be reapplied every two to three hours. If you’re a sweaty person, you’ll want to re-apply on shorter time intervals. We sweat out the barrier on our skin or it dries up as the day goes.
When we apply sunscreen, we tend to miss out on certain areas such as our ears, elbows, and our hairline. We tend to think these areas don’t need to be applied with sunscreen but that’s a wrong thought. These areas are very sensitive and not only can they get a nasty sunburn, they too are places that skin cancer can fester.
