9 Facts about Sunscreen You Probably Didn't Know
Summer is the time of the year in which we get the most out of the sun. And although it’s sexy to have a nice tan, it can be particularly dangerous to expose our skin to the UVB rays without any protection or precaution. If we spend too much time in the sun, it increases the possibilities of suffering from premature skin aging and, what’s worst, skin cancer, the most common of all cancers.
Looking at it from this perspective, we get to understand better why is so important to use sunscreen, not only when you go to the beach or the pool, but every day. And because we care about your skin’s health, we brought you a list of things you probably didn’t know about sunscreen. So, thanks to a research of The Huffington Post, you’ll find out everything you need to know to use your sunscreen correctly.
What you didn’t know about sunscreen
- As time goes by, some active ingredients of sunscreen start to deteriorate and its effectiveness decrease as well. This means that we must pay attention the expiration date of this product.
- Once the sunscreen has expired, we don’t get any protection, but we might get a skin irritation instead.
- Wearing sunscreen won’t stop you from receiving the vitamin D we need to be healthier. In fact, it only takes spending 30 minutes twice a week in the sun to get the recommended 600 IU or 15mcg. By being in the sun longer than that you’re only exposing yourself to the harmful effects of the UVB rays.
- Exposing your this product to hot temperatures can affect its effectiveness.
- Sunscreen can be an excellent ally when it comes to preventing skin discolorations, facial brown spots and reducing the appearance of blotchiness and facial red veins.
- It’s impossible to block out 100 percent of the sun’s rays just with sunscreen. According to the experts, if you apply an appropriate amount of SPF of 30, you will be blocking 96 percent of the harmful UVB rays, while SPF 50 blocks about 98 percent and SPF 75 blocks under 99 percent.
- It can be beneficial to use a two-in-one base/sunscreen, but it’s still recommendable to wear sunscreen under the makeup anyway. Why? Because we wear more sunscreen than we wear foundation, so the level of protection isn’t the same nor as effective.
- To take care of your skin’s health, you must reapply your sunscreen every hour if you’re making some physical activity that makes you sweat or if you’re swimming.This is because sweat and water cause the product to wear off faster.
- If we are used to leaving open the bottle of our sunscreen too much time, we’re exposing it to germs and it can’t get contaminated over time.As a result, its level of protection loses effectiveness.
