While interacting with the SPF is a simple and important task, there is much about the process that is difficult to understand. First of all, what does the SPF numbers even say? And which one are you really using? They go up to 100 – but that's really inevitable, especially when many brands are selling creams and toxins & # 39; SPF 15 & # 39 ;?
We have highlighted these questions and more with a team of dermatologists who are certified by the SPF and the standards we must set when buying or using.
As it turns out, it's not all about the number & # 39; SPF & # 39 ;, which itself can be misleading to most customers. But let's start with:
How the SPF works
Mariana Atanasovski, M.D., has a good fraction of SPF figures: "SPF 30 block 97% of UVB rays, SPF 50 block 98% and SPF 100 block 99%," Atanasovski said. X-rays & # 39; UVB & # 39; those are & # 39; skin & # 39; on your skin, presenting dark spots, wrinkles, and skinny jeans. Let’s pretend that you are totally disgusted by any kind of skin, or that your skin is good for burning only in the sun. In that case, Atanasovski suggests investing in SPF 100. Otherwise, most of us are safe on SPF 50, and it is 98% protected. If you want to make it a little easier, you can speed up SPF 30.
Finally, make sure your sunscreen is labeled as a "broad spectrum," meaning that they also block UVA-induced skin cancers. A few of these are – generally, they are blocked or not restricted. When you find only "wide" products, to be sure. We would like to:
SPF 30 is a Good Place to Start
Most of the skin experts in our survey suggested starting at least SPF 30, as it offers 97% coverage compared to SPF 15 & # 39; s 93%. (Again, the amount of radiation UVB percent blocked.) You will still get a little bit brighter SPF 30, a dermatologist will tell you that is a good thing. As non-dermatologists, we are convinced to move on to this summer and see something positive – as you follow the rest of this advice and say it slowly.
Audra Isaac Grossman says: "Everyone should use at least SPF 30 to meet a variety of needs every day, regardless of whether you plan to spend time outdoors," Dr. Audra Isaac Grossman says. This includes your daily moisturizer, even in winter. We would like to:
The SPF Number is usually incorrect – but not the label's fault
Because of human error, we usually don't get the SPF value we chose. You need to blend in waves more frequently for all its benefits, and re-apply every 60 – 90 minutes, and as soon as you swim or sweat.
Dr. Curtis Asbury says: "No one in the real world has the SPF listed on the bottle," said Dr. No one is using sunscreen sunglasses enough to do so. Real world studies have been conducted that show that the average person wearing sunscreen & # 39; SPF 30 sunscreen & # 39; only gets a small percentage of that rating because they don't use it enough. Therefore, everyone should wear the highest quality clothing they can use. If they use the SPF 70 sunscreen, then they are more likely to actually get SPF 30. ”
It's all about the Contents
All of our respondents do not have to stand for SPF figures in the first place. Some focus on the active ingredients used. “Look for zinc oxide and / or dioxide sunscreen for the best protection,” says Brenda Dintiman, M.D. It is great for sensitive skin and will not cause itching. They all have at least SPF 50 or higher, and will prevent skin cancer and aging. ”

One number to focus on: How often you apply
Again, recycling is key. You cannot cover yourself with a special layer of SPF and expect to keep it all day. Marcy Alvarez, DO, says "After hours of swimming or sweating, your SPF 100 is the same as your SPF 15 if you don't apply regularly." I always recommend spray and air conditioning for those with an active lifestyle. Take a look at the words & # 39; 80-water-resistant & # 39; and & # 39; invisible zinc. "
