Keep your body’s largest organ safe with these 5 facts you should know about skin cancer.

You hear the same advice every summer: Slather on sunscreen and limit your time in the sun. Those rules still apply, but not everyone is getting the message, and rates of melanoma are on the rise.

Although melanoma isn’t the most common cancer – it’s third behind basal cell carcinoma and squamous cell carcinoma – it is the most deadly. In 2021, rates of melanoma are expected to rise by 5.8%, and women under 50 are being hit harder than men of the same age. Two reasons explain the rise. “The overall increase in skin cancers has to do with cumulative sun exposure combined with lack of adequate sun block or protection from UVA/UVB rays,” says Ava Shamban, MD, boardcerti­fied dermatolog­ist in Los Angeles and founder of Ava MD Dermatolog­y, SkinFive Medical Spas and The Box by Dr. Ava. One in five Americans will develop skin cancer by the age of 70.

This summer, get smarter about your sun exposure. Here are five oftenforgo­tten facts you need to know to protect your skin.


You may not think about wearing sunscreen when it’s cloudy or rainy or even during winter. Yet you should. “The most harmful ultraviole­t rays are present every day,” Shamban says. “They don’t retreat in winter and can filter through dark cloud coverage, which is why any uncovered areas of the body at any time of the year are exposed and vulnerable to the damage of the sun’s UV rays.” Easy solution? Make sunscreen applicatio­n as much a part of your daily routine as brushing your teeth. Choose a broad-spectrum sunscreen that protects against UVA and UVB with an SPF of at least 30 and slather it on when you get out of the shower in the morning as you would lotion. Consider using sunscreen anywhere above or below the towel, including your legs, arms, shoulders, décolletag­e, neck, face, ears and hands. The American Cancer Society also suggests a lip balm with sunscreen. You might even add a hand cream, moisturize­r or makeup with sun protection to your daily routine. These won’t replace sunscreen but will o er added support for vulnerable areas that are never covered in your reapplicat­ion plan, Shamban says.


How quickly you go through that sunscreen depends not only on how big the bottle is but also how well you’re applying it. In general, though, aim to go through at least one bottle during the summer, more if you’re sharing that bottle with others. If your bottle lingers, it’s a sign you’re probably not using enough. The Skin Cancer Foundation recommends applying an ounce of sunscreen to your face and body. That’s about the size of a shot glass; for easy reference, keep a shot glass in your bathroom to help you measure it, Shamban says. Your face alone should get a nickel-sized amount, Haimovic says, adding that you should then reapply every two hours. Just watch those expiration dates, as sunscreen breaks down over time. “I’ve seen people who have gotten burns because they used expired sunscreen,” she adds. Once a year, go through all your sunscreen and toss any that have expired.


Although any exposed skin may be prone to developing skin cancer, the skin around your eyes is particular­ly vulnerable because it’s thin and delicate, Shamban says. Roughly 5 to 10% of all basal cell carcinomas occur on the eyelids. While you should always wear sun-protective eyewear when outdoors, choose a darker, polarized lens rated for ultraviole­t protection; most sunglasses don’t have enough UV protection alone. That’s where wearing a wide-brimmed hat with a minimum of three inches and finding shade or using an umbrella can help. Sunscreen is crucial, but if it bothers your eyes, use a mineral version (containing zinc oxide and/or titanium dioxide) for the eye area or try a fragrance-free sunscreen for sensitive skin. Alternativ­ely, use a protective powder with an SPF rating for your eyelids; try a stick formula or one with a “doe foot” applicator, which allows more precise applicatio­n versus your finger, Shamban says. A broad-based sun-protection eye cream will also do the trick.


Being by windows can give your mental health a boost, but know that those windows, whether in your home, office or car, will expose you to harmful UV rays. There are two types of rays – UVA and UVB – and each one affects the skin differentl­y. UVB rays are the classic burning rays, the most common cause of sunburns and the type most associated with skin cancer, says Adele Haimovic, MD, dermatolog­ist in New York and spokespers­on for the Skin Cancer Foundation. Meanwhile, although UVA rays can cause sun damage and also lead to skin cancer, they’re associated more with aging, and it’s these rays that penetrate more through windows. “Most glass does not protect against UVA exposure,” Shamban says, adding that while some of the UVB rays get through, all of the UVA rays do. That’s one reason year-round sunscreen is so critical on exposed parts of your body. To further protect yourself, purchase UV protection shields for car windows. Clothing can even add another layer of protection. Bonus? Look for detergents that wash sun protection into your clothing.

“Most glass does not protect against UVA exposure,” Shamban says, adding that while some of the UVB rays get through, all of the UVA rays do.


While this may be a no-brainer, it’s worth repeating: If you’re logging the miles outside, you’re at an increased risk of skin cancer. “Marathoner­s wear very little clothing and are outdoors for extended periods of time,” Shamban says. To protect yourself, always apply sunscreen when you go out, reapplying as much as you can since you’re sweating so much o . If sunscreen is always dripping into your eyes and stinging them, switch to one with titanium dioxide or zinc oxide, Haimovic says. You can also buy athletic apparel with ultraviole­t protection factor. Wear sunglasses and, if you can tolerate it, a visor or hat. And if possible, plan your workouts so you’re not outside when the rays are at their strongest, generally between 10 am and 4 pm. Bottom line? “Even if the sun doesn’t shine, it’s not a free pass from sun protection,” Shamban says. “Ultraviole­t rays don’t take a vacation, and skin cancer knows no season.”
