There is always a lot of questions regarding sun protection. “When should we apply sunscreen?” or “What is SPF?” are just two examples. As we are aware of this, we decided to gather some of the most frequently asked questions related to sunscreen. If this is something that concerns you, then take a look at the questions below.
What does “SPF” mean?
SPF means Sun Protection Factor. The number that usually follows SPF, indicates how long it would take for UV radiation to burn the skin when out in the sun. This is valid as long as the sunscreen is used exactly as directed on the label. Therefore, the best and most secure option is to always go with the higher protection.
What is “Broad-Spectrum Protection”?
“Broad-Spectrum Protection” is a term used to claim that a sunscreen protects against both UVA and UVB rays. But why is this important? Well, UV radiation is composed of different types of rays including UVA and UVB rays. UVA rays are known to be responsible for photoaging and premature skin aging, concerning the appearance of dark spots and fine lines. On the other hand, UVB rays are related to sunburns and tanning. As you can imagine, both of them can harm the skin and contribute to increasing the risk of developing skin cancer. This is exactly why it is important to choose sunscreens with broad-spectrum protection. We need to be protected from both types of UV radiation.
What quantity of sunscreen should we apply?
To correctly apply sunscreen and achieve the SPF on the label, we should apply approximately two milligrams of sunscreen per square centimeter of skin. This means we should apply about a shot glass (two tablespoons) of sunscreen to the exposed areas. We know this sounds like a lot and truth be told almost anyone applies the recommended amount. However, that is why we should be careful when applying sunscreen to cover all exposed areas, reapply whenever necessary and choose a higher SPF sunscreen.
When should we apply sunscreen?
Every-single-day as the last step of your skincare routine, before make-up. Also, if you know you will be more exposed to the sun, consider taking sunscreen with you a reapply every two hours.
If you are going to the beach, pool, or if you are going to be in a situation of great exposure, apply sunscreen on your face and body about 30 minutes before the exposure. Plus, reapply every two hours, or less if you go for a swim.
Do we need to wear sunscreen all year?
Yes, all year long. Even if it’s wintertime and you cannot see the sun, trust us, the UV rays are there. For example, in the winter they get past the clouds and are reflected by the snow. Also, if you work from home, or if you drive to the office every day, keep sunscreen in your skincare routine, because UV rays can get past windows and reach your skin.
Is it true that sunscreen helps to prevent skin aging?
Sun damage is not limited to sunburn, As we mentioned before, UVA rays are responsible for photoaging and premature skin aging. When the UV radiation reaches the skin, free radicals are produced. These molecules break down proteins from our skin. Of course, we have defenses against them, called antioxidants, but it comes to a point when our defenses cannot overcome the free radicals, and then there is cell and DNA damage. You might have heard about this process, called oxidative stress It is associated with many skin aging signs. It contributes to the development of hyperpigmentation spots and wrinkles, for instance.
In conclusion, we could say that sunscreen is probably the best anti-aging product you will ever buy. And it is never too late to start wearing it every day, as the sun damage is cumulative on the skin. So, if sunscreen is not part of your daily skincare routine, today is a good day to change that!
