5 facts a dermatologist wants you know about sunscreen

Skin cancer The most common cancer in the United Statesand the data of one of the five Americans Develop Skin Cancer Experts for healthy skin recommend that protection is important not only for preventing cancer, but also for anti -aging benefits.

However, there are thousands of products in the market and many social media accounts, blogs and forums, advice and share skin care routines, which means that there is a lot to be separated, especially when it comes to skin health.

There are many misunderstandings and “need sunscreen?”, “Do I need to re -apply sunscreen during the day? When? When? When?” And “Do I need to use sunscreen even in winter?”

Make CNBC talk Dr. Man FriedmanAt the GW Faculty of Medicine and Health Sciences, he shared some facts about the Sunscreen, the President of the Professor and the President of the Dermatology and that may surprise you.

1. Applying sunscreen is as important as brushing your teeth

Many Americans do not think that the application of sunscreen is very important. Only 17% of an adult reported that it uses daily sunscreen. 2024 Survey 2,200 Americans.

Friedman wants to shift the narrative: “I want people to think of the use of sunscreen while brushing their teeth.”

If you don’t leave your house without brushing your teeth, you want you to see the sunscreen in the same way. “Just like we protect our teeth, we need to protect our skin, just like we protect our teeth.” Says.

2. Most people forget to apply sunscreen on their eyelids, ears and lips

Before you go out for the day, you probably apply sunscreen on your face, but there are common areas that are overlooked.

“I think many people avoid lips that are more sensitive to damaging UV radiation, because some of our skin has missing things.” If you’re mistaken to get sunscreen in your mouth, there are lip balm with SPF.

In addition, people forget to apply sunscreen around their eyes and eyelids. Research confirms Quite common. Friedman is even more sensitive to injury caused by UV radiation because the skin of your eyelids is very thin.

Other areas that people miss are their ears. “I see a lot of skin cancer in what is called Helical rim.

“My patients, ‘I’m glad you get the face. Just make an extra gushing for the ears, neck and hands.’ This is probably a daily exposure.

3. There is no difference or cost difference, but higher SPFs are more efficient

“If you are not SPF 15 or higher, you cannot say that it provides protection against a sunscreen skin cancer or according to accelerated skin aging.”

. Recommendation of the American Academy of Dermatology For sunscreen:

• SPF 30 or higher
• Waterproof
• WIDE Spectrum Protection (protecting against UVA and UVB rays)

Friedman can protect about 97% of the SPF 30 block UVB rays and SPF 50 against approximately 98%. Most people say, “Sun cream can not get 100% protection unless two -square square square square is applied. This is too much sunscreen,” he says.

“So I push it for higher SPFs. There is really no difference in terms of feeling and texture or cost.

4.

Dermatologists recommend re -applying sunscreen every two hours, but Friedman is realistic about how difficult it can be.

Orum I’m applying in the morning, but I’m not going out and I’m not really close to the windows, or he says. Usually, it is applied only once a day.

It suggests to be more intentional about the application every two hours on the days when it planned more than normal. If you are sweating too much or if you leave a pool, you probably lose your sunscreen layer and you should also re -apply again.

“You should technically apply again every two hours. I say technically, because I’m a realist, and who will actually do it, Friend says Friedman. “Do your best.”

5. You need to wear sunscreen in every season, even winter

“Sun protection is something for a year, Friend says Friedman. “Depending on the time of the year, depending on where you are in the world, there are several factors that will affect the UV index. So I think it is not suitable for one body.”

Even if the UV index is relatively low, Friedman realizes that people are more likely to remember using sunscreen in general when they depend on the habit of daily application.

The name has a common skin condition dermatoporosis This often affects people when they grow up. The situation explains how the skin can be fragile and rotten and says, “The most commonly occurs in the forearms, because we forget to protect,” Friedman says.

“These big purple spots on the arms or these white, small star -shaped scars, this chronic injury we have accumulated over time. You can guarantee you in the winter months we probably do not protect ourselves appropriately, not from the summer, not too much accumulation.”
