Key Highlights
Sun Protection Factor, or SPF, shows how well a sunscreen can protect your skin from UVB rays that can burn you.
It is important to pick a “broad-spectrum” sunscreen, because this type will help you keep safe from both UVA rays that age your skin and UVB rays that burn it.
A sunscreen with SPF 30 can block about 97% of UVB rays. A sunscreen with SPF 50 stops about 98%. So, the extra sun protection between the two is small.
For daily use, dermatologists say it is best to go with a broad-spectrum sunscreen and look for at least SPF 30 for good sun safety.
You have to put sunscreen on the right way. Use about one ounce for your whole body and put more on every two hours, or when you are sweating or swimming.
Mineral sunscreens that use non-nano zinc oxide are safe for you and the ocean and are a good way to practice sun protection without chemical-based creams.

SPF means Sun Protection Factor. You read this word quite a lot when people talk about sun block. But do you know what it does for your skin? The SPF value tells you how well the sunscreen can protect you from UVB rays. The UVB rays from the sun are what give you a sunburn.Sun protection is not just about blocking UVB rays. It is also important to keep your skin safe from UVA rays. UVA rays can make your skin get old faster. In this part, we will talk about what the SPF value means. You will know how it works with broad spectrum sunscreen to give you full sun protection from both UVA and UVB rays.SPF Explained: Definition and What It RepresentsThe Sun Protection Factor, or SPF, shows how well a sunscreen can protect your skin from UVB rays. This number tells you how much longer your skin will stay safe in the sun when you use the product, compared to if you have unprotected skin. For example, if you put on SPF 30 as you should, it will take 30 times longer for your skin to get red than if you were not using any sun protection at all.The drug administration checks and tests the SPF for sunscreen in a set way. The numbers you see, such as SPF 15, 30, or 50, show the amount of UVB rays the sunscreen can block. A higher SPF gives more sun protection. But after a certain point, picking a much higher SPF will not add a lot more protection. The difference in how much UVB rays the sunscreen blocks does not go up by much when you use a higher SPF.SPF helps you pick the right sun protection. It lets you know how much blocking you will get from UVB rays. This is important because it keeps your skin safe from sunburn and skin damage.How SPF Works: UVA, UVB, and Broad Spectrum ProtectionThe SPF rating tells you how much uvb protection you get. But the sun makes two main types of uv rays that are not good for your skin. It is very important to know about these types of uv rays for good sun safety.
UVB Rays: People also call these the "burning" rays. Most of the time, UVB rays stay on the top layer of your skin. They are the main cause of sunburn.
UVA Rays: People call these the "aging" rays. UVA rays go deeper into your skin. They lead to fine lines and make your skin wrinkle or age too soon. UVA rays can also pass through glass.
SPF is about uvb protection. So, you need to get a sunscreen that says "broad spectrum" on the label. This type of sunscreen helps to keep both uva rays and uvb rays away from your skin. If you do not use a broad spectrum sunscreen, the sun’s rays can still harm your skin. You may not see a sunburn, but your skin could still get a lot of damage from the uvb rays and uva rays.Decoding SPF Numbers: 15, 30, and 50When you stand in the sunscreen aisle, you will see many choices. You see SPF 15, SPF 30, and also SPF 50. A lot of people do not know which spf number is best to use. Some think that a higher spf number will always mean much better protection for them. The truth is, the level of spf does not give that much more help as you may think.To choose the best SPF for you, think about what your skin needs. The goal is to find the SPF number that works best for you. Let’s see what each SPF number can do for your skin. We will also talk about some common myths people have about higher SPF and if those give better protection.What Does SPF Do? Comparing Levels of ProtectionDifferent SPF numbers block different levels of UVB rays. A higher SPF does give you more protection, but the extra coverage is small. The American Academy of Dermatology says you should use an SPF of 30 for good daily protection.Here is a look at how much UVB rays each common SPF level blocks:
SPF Level
UVB Rays Blocked
SPF 15
93%
SPF 30
97%
SPF 50
98%
SPF 100
99%
As you can see, an SPF 30 sunscreen blocks most UVB rays. A higher SPF can lower the risk of sunburn a bit more, but there is not any sunscreen that blocks all of the sun's rays. The best protection is using the right SPF, putting it on the right way, and following other sun-safe habits.SPF 30 vs. SPF 50: Is There a Significant Difference?Many people believe that when you pick a higher SPF number, you are getting a lot more safety from the sun. But that’s not true. If you check the SPF 30 and the SPF 50, you will see that both stop almost all of the UVB rays, with just a 1% change. SPF 30 blocks about 97% of the UVB rays. SPF 50 blocks around 98% of the rays. For daily use, this small change in the higher SPF number does not matter much.The main problem with a high SPF number or higher SPF is that it can give people a false sense of security. People may feel that using a high SPF like SPF 50 means they do not need to put on more sunscreen again. Some may think they can stay in the sun for longer when they use high SPF. But this is not true. No matter what the SPF number is, you need to put sunscreen back on every two hours. Another problem with higher SPF sunscreen is the way the higher number is achieved. Using chemical filters to achieve higher SPF has its cost: toxicity of chemicals can increase your chances of skin cancer, harm your microbiome and can cause chemical induced dysbiosis. Chemical filters are also harmful to the environment, coral reefs and marine animals and thus banned in many countries and islands.For daily use, SPF 30 can give good protection from UVB rays. Picking a sunscreen that says it has a high SPF number will not always mean you get better protection. This is true if you do not use it the right way. It is much more important to use your sunscreen the right way every time, not just look for a higher SPF number or a high SPF.Choosing the Right Sunscreen for Your NeedsChoosing the right sunscreen is more than just picking an SPF number. You have to think about your specific skin. You also need to think about how much sun exposure you get. It matters what you do each day, too. The best sunscreen is the one you will use every day.If you have sensitive skin, spend a lot of time in outdoor activities, or want sunscreen for daily use, you should think about these things. In the next parts, you will see how to pick the best SPF number for you. You will also read about other things that matter when you choose your sunscreen.How Much SPF Is Enough for Daily Sun Exposure?For daily use, the Skin Cancer Foundation and many skin doctors say you should use a broad-spectrum sunscreen with an SPF level of 30. This will help protect you from sun damage and lower your risk of skin cancer. You can get sun damage even when you do things like walk to your car or sit near a window. It is also important to use the right amount of sunscreen, as well as pick the right SPF number. This way, you get good protection every day.To get all the safety from the sun, you have to use the right amount of sunscreen. Here are some best practices you can follow:
Use about one ounce when you want to cover your whole body. This is about the same amount as a shot glass.
For your face, use a bit that is about the same size as a nickel.
Do not forget to put some on your ears, neck, and the tops of your feet.
Many people do not put on enough sunscreen. This means it does not work as well for them. Using the right amount of sunscreen is very important. It protects your skin from uv damage each day. This will also help lower your chance of getting skin cancer from UVA exposure.Factors Influencing SPF Selection: Skin Type and ActivityThe best SPF for you may not be best for everyone. You should think about your skin shade and the things you do each day before you choose one. If you have fair skin that can burn fast, you may need a higher SPF. But the most important thing for all people, no matter your skin color, is to use sunscreen the right way, every day.Keep these things in mind when you pick your sunscreen:
Skin Type: If you have fair skin or your skin is sensitive, using a higher SPF can help you feel safe. All skin, even darker skin and darker skin tones, need some protection from the sun’s rays.
Activity Level: If you do outdoor activities, swim, or play sports and sweat, you should use a water-resistant sunscreen.
Geographic Location: If you are in the mountains or close to the equator, the sun’s rays are more strong. This means you may need to put on sunscreen more often.
It does not matter if you use SPF 30 or a higher spf. Sunscreen will last for the same amount of time, which is around two hours. To keep your skin safe, you need to put it back on after two hours.Safe Sunscreen Ingredients: Why Non-Nano Zinc MattersWhen you choose a sunscreen, you need to check what is in it. Do not just look at the SPF number. There are two main types of sunscreens. These are chemical sunscreens and physical (mineral) sunscreens. Chemical sunscreens take in uv rays. Physical sunscreens sit on your skin. They send the rays away from you. A lot of people with sensitive skin go for mineral sunscreens. They feel these are not as tough on the skin.One of the best things you can find in a physical sunscreen is non-nano zinc oxide. This type of zinc oxide is made in bigger pieces. It stays on top of your skin and does not go into your bloodstream. It keeps out most types of uv rays and does its job well. Non-nano zinc oxide is also a key part of reef safe sunscreen. It does not hurt the ocean or sea life. With this ingredient, you help keep your skin safe and also take care of the environment at the same time.Beyond SPF: Benefits of OM Botanical SPF 30 with Raspberry Oil and Micro AlgaeA good sunscreen should give you more than just sun protection.

Babies have delicate and sensitive skin that can easily get sunburned, so it's essential to choose a sunscreen that is chemical free and plant based. Look for a broad-spectrum sunscreen that contains non-nano zinc oxide as the active ingredient, as it provides effective protection without harsh chemicals. It's recommended to use SPF 30, ensuring it shields against both UVA and UVB rays. Additionally, opt for water-resistant formulas if your child will be swimming or playing in water. Always apply sunscreen generously on all exposed skin, including hard-to-reach areas like ears and the back of the knees, and reapply every two hours or after swimming. Remember, sun protection for babies and children goes beyond just sunscreen; dressing them in protective clothing, hats, and sunglasses, and seeking shade during peak sun hours are also vital parts of keeping their skin safe from harmful UV radiation.Duration and Frequency of SPF EffectivenessThe duration and frequency of SPF effectiveness are critical factors in ensuring optimal protection against harmful UV rays. Once applied, the effectiveness of sunscreen can diminish over time due to various activities like sweating, swimming, or simply moving about, which can cause the product to wear off. Generally, sunscreen should be reapplied every two hours for continued protection, regardless of the stated SPF number. If you're engaging in activities that cause heavy perspiration or if you're swimming, it's advisable to apply a water-resistant formula and reapply immediately after drying off. Understanding these aspects of sunscreen application will enable you to maintain effective sun protection and enjoy the outdoors responsibly.SPF Misconceptions on Social MediaWith the rise of social media, there has been a surge of misinformation surrounding SPF and its effectiveness in protecting skin from harmful UV rays. Many users spread myths, such as the belief that a higher SPF provides significantly better protection, when in reality the difference is marginal. For instance, SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks approximately 98%. Additionally, some assume that once they're protected with sunscreen, they can stay out in the sun indefinitely, which is far from the truth. Reapplying every two hours and after swimming or sweating is essential for maintaining that protective barrier. Moreover, there’s a misconception that darker skin tones don’t need sunscreen, which can lead to an increased risk of skin damage. It's crucial to demystify these myths and educate others on the importance of proper sun protection for all skin types, regardless of trend-driven narratives online.ConclusionTo sum up, it is important to know about SPF to keep your skin safe from harmful UV rays.
