SUNSCREEN IS A MUST FOR YOUR DAILY SKINCARE ROUTINE

Sunscreen is one of the most important steps in a simple skincare routine. As we’ve learned, your basic daily skincare routine should include a cleanser, toner, moisturizer, and sunscreen. Great sunscreens offer broad-spectrum protection against both UVA and UVB rays. UVB rays are responsible for sunburns and cellular damage that increases your risk for skin cancer. Until recently, sunscreens only blocked UVB rays. UVA rays don’t cause sunburn, but they penetrate deep into your skin to create fine lines and wrinkles. The Environmental Protection Agency estimates that your lifetime exposure to UVA rays causes 90% of skin changes due to aging. Many companies have begun offering broad-spectrum sunscreens that protect your skin from both harmful types of UV rays. If you want healthy, youthful skin, you should apply sunscreen daily. In this article, we’ll explore the different types of sunscreen and how to choose the right type for your skin.

TYPES OF SUNSCREEN

There are two basic types of sunscreen, but they protect the skin in very different ways. Physical sunscreens prevent the sun’s UV rays from reaching the skin by creating a barrier over the skin to block UV rays. Common ingredients in physical sunscreens are titanium dioxide and zinc oxide. The ingredients in a physical sunscreen are often less irritating for those with sensitive skin, but they can leave a white cast and may not be suitable for people with darker skin tones. Chemical sunscreens prevent the sun’s UV rays from reaching the skin by chemically converting the rays to heat, then releasing the heat from the skin so that it doesn’t cause a burn. Common ingredients  in chemical sunscreens.

Chemical sunscreens have smaller molecules than physical sunscreens. They are often thinner, so you don’t need to use as much to protect your skin. However, people with sensitive skin may find the chemicals irritating. If you have sensitive skin or a condition such as eczema, you’ll probably do better with a physical sunscreen because your skin doesn’t absorb the ingredients. Children’s sunscreens are also a good option because they’re formulated to be gentle enough for delicate baby skin.

WHAT DOES SPF MEAN AND HOW MUCH DO I NEED?

SPF means sun protection factor. It measures how long a sunscreen will protect your skin from UVB rays. For example, if you usually get a sunburn after 10 minutes, an SPF 15 sunscreen would protect you fifteen times longer than it takes to burn without protection, in this case, 150 minutes. People with darker skin tones or those who do not burn easily will get sufficient protection from SPF 15 sunscreens for daily use. However, they should use a higher SPF for prolonged time outdoors. We recommend that people with fair skin and/or a family history of skin cancer use SPF 30 or higher daily.

APPLYING SUNSCREEN

Believe it or not, most people do not get the full SPF protection advertised on a sunscreen bottle because they don’t apply enough. To cover your entire body adequately, you need to use one ounce of sunscreen. For reference, that’s about the size of a typical shot glass. Physical sunscreens are effective as soon as you apply them. However, chemical sunscreens need 15 – 30 minutes to activate before they offer protection

Many sunscreens wear beautifully under makeup, so there’s no reason to skip this essential step. If your current sunscreen pills under your makeup or causes your foundation to separate, keep searching until you find one that pairs well with your makeup. You can streamline your morning skincare routine by using a moisturizer that also has sunscreen in it. If you’re spending a lot of time in the sun, make sure that you reapply your sunscreen every two hours. If you’re swimming or sweating, you’ll need to apply it more often. According to the FDA, “water-resistant” sunscreens maintain their SPF for 40 minutes in the water, while “very water-resistant” sunscreens maintain their SPF for 80 minutes. Take your sun protection to the next level by using lip balms with SPF.

 Wearing broad-brimmed hats protects your head and ears. Since typical clothing does not offer sun protection, you may want to consider wearing specialized UPF (ultraviolet protection factor) clothing for long days outside. “In the medical community, there is a significant frustration about the lack of availability of some of the sunscreen active ingredients,” Henry Lim, a dermatologist at Henry Ford Health, in Michigan, told me. The more filters are available to formulators, the more they can be mixed and matched in new ways, which stands to improve not just the efficacy of the final product, but how it feels and looks on your skin, and how easy it is to apply. On a very real level, making sunscreen less onerous to use can make it more effective

“The best sunscreen is going to be the one you’re going to use often and according to the directions,” Dobos said. Skin cancer is the most common type of cancer in the United States, anFor many dermatologists, these lengthy regulatory battles and widespread issues with regular usage also underline a common recommendation that tends to go unheard by patients: Sunscreen is great, and sunscreen from Europe, Australia, and Asia may be better, but even the best, most cutting-edge SPF lotion is just one part of keeping your skin healthy.

Floppy hats, big beach umbrellas, or loose, high-coverage clothing might not be your ideal beach look while you’re young, but if you can mostly cover up and stick to the shade, your elderly self will thank yd by one estimate, one in five Americans will develop it in their lifetime. The government currently allows 17 filters in American sunscreens, nine of which are rarely used, because they have undesirable side effects or because cosmetic chemists find them difficult to blend into the kinds of products that people like. The eight that you will find in the products at your local drugstore still leave something to be desired.

 “The ingredients that we have to work with can cause some challenges in creating a really elegant formula,” Kelly Dobos, a cosmetic chemist who teaches at the University of Toledo, told me. That’s especially true when filters are used in the concentrations necessary for high SPFs, she said. Maximum protection can sometimes mean maximum chalkiness or oiliness, although a skilled formulator will try to counteract these effects with tweaks to the formula or manufacturing process.

 

A sunscreen that has an unpleasant texture or turns your skin a strange color might be tolerable for a one-off excursion to the beach or an afternoon in the cheap seats at a baseball game, but it wouldn’t exactly encourage thorough and repeated applications of a sunscreen, which is necessary no matter which product you use. For everyday use, which is widely recommended by dermatologists, the obstacles are even harder to clear, from a formulation standpoint: Oily products don’t play nice with makeup, while chalky products look wild on pretty much everyone, especially people with darker skin tones. Adam Friedman, a dermatologist at George Washington University, told me such concerns are a huge obstacle for his patients. “You can have the best filter in the world,” he said. “If the vehicle in which that ingredient resides is visibly unacceptable or physically unacceptable in terms of application, it doesn’t matter.”
