Understands Solar Rays: UVA, UVB and FPS
This is a simple guide to UVA, UVB and FPS rays and how you can protect your skin from the sun. When it comes to protecting the body from the sun, it is important to understand why sun protection is important for all people, every day.
Let’s analyze and eliminate any confusion regarding sun protection. We usually see acronyms in our skin protection products, in cosmetics and in clothing, but do you know what it means?
- SPF = Solar Protection Factor
- UVA = Ultra Violet A (long wave)
- UVB = Ultra Violet B (short wave)
To protect the skin, we need to be aware of the damages caused by UVA and UVB rays. They are two different types of radiation that can damage the skin. To make it simple, remember UVA as the rays of aging, and think of UVB as the rays that burn the skin.
UVA rays can cause aging of the skin
UVA rays are responsible for the aging of the skin and wrinkles, and can contribute to skin cancer. Because UVA rays traverse the ozone layer easily, they contain the most amount of sun exposure. UVA rays pass through clouds, glass and clothing. You may not feel them, but they are present.
UVB rays can cause burns
UVB rays are responsible for sunburns and cataracts, As they affect the immune system. Most importantly, UVB rays also contribute to skin cancer.
The Sun Protection Factor (SPF) is found in sunscreen products, and does not tell you the protection you are going to receive, but it gives you an idea of how long you can stay Under the sun before the skin begins to burn. And all people are different. FPS ONLY applies to UVB rays. Does not apply to UVA rays. The FPS in the products comes in several levels, including FPS 15, FPS 30, FPS 50 and more. Here’s how it works: let’s say your skin starts to flush after being 10 minutes under the sun. You’re going to take that number and multiply it by the number of FPS you’re using.
If you use a product with an SPF 30:
– 10 minutes x 30 (FPS) = 300 minutes
– Divide 300 minutes for 60 minutes equaling 1 hour
– 300 minutes / 60 minutes = 5
– The result: approximately 5 hours of protection against Standard solar rays
If you are on the beach or exposing yourself directly to the sun’s rays for an extended period of time, then always use preventive measures with sun protection and sun protection factor. It is important not to create a false sense of confidence when it comes to sun protection.
Many products are not water resistant, so you can not rely on five hours of protection if you are swimming or exercising. Also, most sunscreens are for normal sun exposure, Not for when you spend all day in the sun. If you are on the beach or doing sports, you should consider a stronger sunscreen than usual. And always apply one, two, three or as many times as necessary.
In the United States, many sunscreen products are over-the-counter.
