Sunscreens have become an indispensable part of our daily routine. Whether we're heading to the beach or simply enjoying a sunny day in the city, sunscreen is what protects us from the sun's harmful rays. However, there are some shocking truths about sunscreen that you may not know. In this article, we'll reveal seven science-backed facts about sunscreens that will help you better understand how they work and how you can best use them to protect your skin. This is the truth about sunscreens!
When we talk about sunscreens, we often come across various myths and misconceptions surrounding their use and effectiveness. Some people believe that sunscreen is only necessary at the beach or that a higher SPF is always better. Others believe that the sunscreen completely blocks all the sun's rays, or that the waterproof sunscreen is truly 100% waterproof. This is the truth about sunscreens!
But scientific facts often contradict these myths. The truth is that understanding how sunscreens work and how to use them correctly is key to protecting our skin and keeping it healthy and beautiful.
In the rest of this article, we're going to reveal seven shocking truths about sunscreens that are based on scientific facts, and dispel some of the most common myths surrounding these must-have sun protection products—that is, the truth about sunscreens!
#1 Sunscreens do not block all UV rays
You might think that sunscreen protects you completely from the sun's rays, but that's not true. Sunscreens are designed to block UVB rays that cause sunburn, but they don't block all UVA rays, which can penetrate deeper into the skin and cause premature aging and skin damage. That's why it's important to choose a broad-spectrum sunscreen that blocks both UVA and UVB rays.
#2 Higher SPF does not necessarily mean better protection
SPF (Sun Protection Factor) is the measure we use to determine how much sunscreen can protect our skin from UVB rays. However, a higher SPF does not necessarily mean better protection. According to the American Academy of Dermatology, SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. The difference is minimal and does not necessarily justify the higher price.
#3 Sunscreens may contain harmful chemicals
Some sunscreens contain chemicals such as oxybenzone and octinoxate, which have been linked to hormone disruption and damage to coral reefs. That's why it's important to check the ingredients of your sunscreen and opt for those that contain safer ingredients like zinc oxide and titanium dioxide.
#4 Sunscreens are not 100% waterproof
Even though some sunscreens are labeled as "water resistant," that doesn't mean they remain effective when they get wet. The FDA (Food and Drug Administration) says that no sunscreen is completely waterproof and that sunscreen should be reapplied after swimming or sweating.
#5 Sunscreen is not enough
Although sunscreen is an important part of sun protection, it is not enough. Doctors also recommend wearing protective clothing, such as wide-brimmed hats and long sleeves, and seeking shade during the sun's strongest rays.
#6 Sunscreens have an expiration date
Like all skin care products, sunscreens have an expiration date. After this date, the sunscreen may no longer be effective. Check the expiry date on the packaging and replace the sunscreen when it has expired.
#7 Some sunscreens can cause allergic reactions
Some people are allergic to ingredients in sunscreens. If you experience redness, itching or other symptoms of an allergic reaction after using sunscreen, stop using it and consult your doctor.
Sunscreens are vital to protect our skin from the sun's harmful rays. This is the truth about sunscreens! However, it's important to be aware of these seven truths about sunscreen so we can make informed decisions about protecting our skin. Remember that the best defense against the sun is a combination of sunscreen, protective clothing and smart habits, such as seeking shade during the strongest rays of the sun.
