4 Surprising Times You Need to Wear Sunscreen
Medical review by Tanya Sperber, APRN
You know you’re supposed to wear sunscreen every day, even on cloudy days and in winter, but there are times when you probably wouldn’t think to bother with it. For example, what’s the point if you’re going to spend most of your day in your office?
Surprise! You can be exposed to ultraviolet (UV) rays in some common places that aren’t exactly outdoors. Over time, this exposure may contribute to an increased risk of wrinkles and skin cancer.
Prepare to slather on sun protection when you find yourself in the following situations.
Sitting by a window
Windows protect you from the sun’s rays, right? Yes and no. Glass blocks most UVB rays, the ones that cause sunburn. That’s why many people assume it’s fine to sit by a sunny window without wearing sunscreen. But according to the Skin Cancer Foundation, more than 50% of UVA rays, which are the main cause of premature aging and also contribute to some skin cancers, pass through glass.
If you’re sitting next to a window, or even if you’re a few feet away from it, it’s a good idea to wear sunscreen. For maximum protection, choose a broad-spectrum sunscreen with an SPF of 30 or higher.
"The best way to incorporate sunscreen in your regimen is to find one you love," said Tanya Sperber, APRN, a board-certified advanced practice registered nurse with Water's Edge Dermatology. "Elta MD Elements is a lightweight tinted sunscreen women can apply everyday prior to applying makeup. This sunscreen provides all the benefits of a physical barrier sunscreen without feeling heavy on the skin, apply makeup over or just apply sunscreen and go. A great non-tinted option for men is Elta MD Sheer - it works well for men with facial hair, rubs in completely and if you’re not sweating or swimming, you’re protected all day with a barrier zinc sunscreen."
If your desk or favorite perch is near a window, consider installing UV-blocking window film for extra protection. These block up to 99.9% of UV radiation and are available in a variety of tints. You can have window film professionally installed or buy it at a home improvement store and install it yourself.
Driving your car
Does the left side of your face have more wrinkles or age spots than the right? Driving may be the reason.
While the windshield of your car blocks most UVA (and UVB) rays, your side windows may provide less protection. A 2016 study found that while windshields in a car blocked an average of 96% of UVA radiation, the side windows blocked an average of just 71%.
The difference is due to the types of glass. Windshields are made of two plates of glass with a layer of plastic between to make them shatterproof. Side windows don’t have that plastic layer, which is what provides most of the windshield’s UVA protection.
Experts suspect that weaker UVA protection from side windows may help explain why skin cancer is more common on the left side of the body. So, if you have a daily commute or spend long periods of time in a car, wear sunscreen. Do so even if the side windows are tinted, since the level of UVA protection that tinted windows provide varies. Remember to apply it to your arms, hands, and face.
Keep the sunscreen handy, but don’t store it in the car. The heat that gets trapped in the car can break down the chemicals in sunscreen and make it less effective.
You can also protect yourself by installing UV-blocking window film on your car’s side windows.
Traveling by plane
If you find yourself in a window seat on your next flight, you’ll need more than your boarding pass before takeoff: You’ll need a thorough application of sunscreen, too.
At 30,000 feet, the sun is much stronger than at ground level, and windows on planes (and buses and trains) may not provide adequate protection from UVA rays.
While the risk of sun damage and skin cancer appears to be higher for pilots and flight crew members than passengers, it’s still smart to wear sunscreen when you fly. Just remember that the Transportation Safety Administration currently allows no more than 3.4 ounces of sunscreen in a carry-on.
Getting a gel manicure
Love gel manicures? You’re not alone. Gels make manicures last longer compared to nail polish, but they have to be set using nail lamps that emit high-intensity UVA light.
The risk of UV damage and skin cancer from the lamps, if any, is probably low. A recent review of medical literature did not find evidence of an increased risk of skin cancer in people under 40 who’ve had gel manicures. Still, the American Academy of Dermatology suggests applying sunscreen to your hands protect yourself. If you prefer, you can wear dark, opaque gloves with the fingertips snipped off.
If you get gel manicures regularly, consider saving them for special occasions.

Vitamin C Serum Benefits: Yes, They’re Real
Medical review by Gioconda “Gio” Boaz, PA-C
Vitamin C serum has become one of the most popular skincare products for the face, and for good reason. Who wouldn’t want a serum that can improve the appearance of fine lines and wrinkles, fade dark spots, prevent and treat sun damage and give skin a healthy glow? The claims may seem too good to be true, but the benefits are real according to one skin care provider.
“Vitamin C has been known to improve skin for years, but it didn’t get the same amount of attention that other skin care ingredients did until recently,” said Gioconda “Gio” Boaz, PA-C, a board-certified physician assistant at Water’s Edge Dermatology.
“I think vitamin C serum is popular now because more information is surfacing on how it boosts the skin’s natural protection against sun damage, fights inflammation and produces a great cosmetic advantage.”
How vitamin C serum works
Vitamin C improves skin’s appearance in several ways. As an antioxidant, it protects against damage caused by unstable molecules called free radicals. Sun exposure increases free radical production. While your diet provides some vitamin C, using a vitamin C serum increases the concentration of the vitamin in your skin. And unlike sunscreen, it can’t be rubbed off. In fact, once vitamin C is absorbed, the protection it offers seems to last for days.
The vitamin also helps the body synthesize collagen and increases skin cell turnover. This means that dead and damaged skin cells are replaced by new ones more quickly, making skin look brighter.
Vitamin C serum can help address:
- Hyperpigmentation. Increasing cell turnover can lighten sun spots (also called age spots), dark spots caused by acne, and dark patches caused by melasma. “One of the great things about vitamin C is that it’s safe for pregnant women, who are vulnerable to developing melasma,” Boaz said.
- Fine lines and wrinkles. Faster cell turnover combined with increased collagen can make wrinkles less noticeable.
- Sun damage. By neutralizing free radicals, vitamin C reduces and helps prevent sun damage. It also works to prevent the sun’s rays from suppressing the immune system. This immune suppression is thought to play a role in the development of melanoma and non-melanoma skin cancers.
Choosing the best vitamin C serum
Vitamin C serums range in price and the amount of vitamin C they contain. You don’t have to choose one of the pricier options if it’s not in your budget.
“Any vitamin C serum, as long as it’s a “stabilized” vitamin C, is going to be beneficial, and expensive doesn’t always mean better,” Boaz explained.
The amount of vitamin C in serums typically ranges from 5% to 20%. While vitamin C is generally well tolerated, it is acidic and can therefore irritate sensitive skin. Boaz recommends starting off with a lower concentration. Move to a higher concentration if you’re not seeing results and if your skin can tolerate it.
Packaging is also key. Vitamin C degrades quickly, particularly when it’s exposed to light. So, an opaque container is a must.
Application and storage tips
If you have sensitive skin, start by using vitamin C once a day. Apply it in the morning to take advantage of the added protection against sun damage. (Sunscreen is always a must.) For people with sun-damaged skin, Boaz recommends gradually switching to a twice-a-day routine.
Apply vitamin C serum after washing your face and before applying moisturizer and sunscreen. Don’t apply too much serum or you’re wasting your money — three to five drops are plenty.
“It’s normal to feel a brief tingling sensation when you use it. This usually dissipates after a couple of weeks,” said Boaz. “Anything beyond that may mean the serum is too strong for you. It’s also possible that you’re allergic to one of the ingredients.”
To prevent vitamin C serum from degrading, keep it stored in a dark place and replace the cap tightly after use. You can tell when it has degraded by its color. Most serums are pale yellow and turn orange or brown when they spoil. If yours has degraded, it’s time to throw it out.
For best results, apply vitamin C serum every day, Boaz advised. “The protective antioxidants immediately shield your skin. It can take about two months of regular use to start seeing cosmetic results, but it’s definitely worth the wait.”

Sun Safety
Summertime is fun time to spend outdoors. But in sunny Florida, that means more exposure to the sun’s ultraviolet (UV) rays. Those UV rays can damage unprotected skin in as little as 15 minutes and even lead to skin cancer. Here are some tips to keep you sun safe all year long.
Seek Shade
One of the easiest ways to reduce your exposure to damaging UV rays is to get in the shade. Seek shade under a tree, umbrella or another shelter in order to reduce your risk of sun damage. You’ll help your skin look younger longer and lower your risk of developing skin cancer.
Protective Clothing
Cover up with long-sleeved shirts and long pants when you can to protect your skin from the sun’s harsh UV rays. There are clothing options available that contain a UV protectant built into the fabric. Also, remember that a wet t-shirt provides less UV protection than a dry one, and darker colored clothing protects better than light-colored clothing. Don’t forget to top it off with a hat with a brim all the way around that shades your face, ears, and back of the neck. If you choose a baseball cap instead, be sure to protect your ears and the back of your neck with sunscreen of at least 30 SPF.
Sunglasses
Choose sunglasses that are labeled UV protectant to reduce the risk of developing cataracts. Most of the sunglasses sold in the U.S. block both UVA and UVB rays. Sunglasses also protect the skin around your eyes from sun damage, and wrap-around sunglasses are an excellent option to block UV rays that might sneak in from the side.
Wear Sunscreen
Choosing the right sunscreen can be daunting, so we recommend following these four rules to make it easier:
- Broad-spectrum – Broad-spectrum sunscreen protects the skin from both ultraviolet A (also known as UVA) and ultraviolet B (also known as UVB) rays. Both of these rays can cause skin cancer.
- SPF 30 or higher – The sun protection factor (SPF) rating indicates how well a sunscreen protects you from the sun by blocking harmful UVB rays. Choose a sunscreen with SPF 30 or higher to make sure you are protected.
- Key ingredients – Look for active ingredients like ecamsule, avobenzone, titanium dioxide, sulisobenzone or zinc oxide. Beware of products that include oxybenzone or octinoxate which are harmful to the environment. Some areas of Florida have banned the sale of sunscreen with oxybenzone and octinoxate because these chemicals can damage coral reefs.
- Avoid tanning oils – They generally do not provide enough protection against the harmful effects of the sun.
How to Apply Sunscreen & How Often
To get the maximum protection from your sunscreen, follow these recommendations:
- One ounce of sunscreen is considered the right amount. Cover all exposed areas of the body thoroughly. Don’t skimp. Many people don’t use enough sunscreen.
- Apply sunscreen 15 to 30 minutes before going in the sun. Don’t forget the tips of the ears, feet, back of the legs and bald spot (if you have one). Reapply sunscreen every two hours and use a UV-protective lip balm to cover your lips.
- If you are exercising or are in the water, it’s a good idea to get a sunscreen that is resistant to water and sweat. The FDA defines water resistant to mean that the SPF level stays effective after 40 minutes in the water. Very water-resistant means it is effective after 80 minutes of swimming. These sunscreens are not waterproof, so reapply regularly.
Protecting your skin from the harmful rays of the sun can help you look younger and prevent skin cancer. Just to be on the safe side, be sure to get a skin cancer screening every year, so if you do develop skin cancer, it can be detected and treated early.

Dark Spots & Hyperpigmentation
No one wants dark spots and skin discoloration, but the fact is millions of Americans have them. Hyperpigmentation is a general term that refers to a condition where the skin is discolored or darkened. Dark spots caused by hyperpigmentation can make you look older and can be the result of several factors including acne scarring, sun damage or inflammation from an eczema flare-up. Melasma is a type of hyperpigmentation that appears as a form of skin discoloration and is made worse by sun exposure. It affects more than five million Americans, mostly women. In order to properly treat these conditions, it’s important to understand the differences between them.
Hyperpigmentation
Hyperpigmentation includes any darkening of the skin. Acne, sun exposure, and skin rashes can stimulate the pigment-making cells of the skin, called melanocytes. When that happens, those cells often produce a surplus of pigment into lower levels of skin, causing a dark spot. The deeper the pigment, the harder it is to treat. It works much in the same way as a tattoo. The severity of skin darkening varies. When skin is consistently exposed to harmful UV rays without sunscreen protection, it will be more difficult to treat than a dark spot left over from a pimple that has been shielded from the sun.
Melasma
Melasma is a type of hyperpigmentation, more commonly seen in women and especially women with darker skin tones. It is believed to be triggered by UV exposure and hormones that increase during pregnancy and after starting oral contraceptive use or other hormonal therapies, which can make melasma tougher to treat than traditional hyperpigmentation.
You can usually tell if you have melasma based on the appearance of the spot, which typically appears as symmetric blotchy hyperpigmented patches on the face, often on the cheeks, nose, forehead, chin, and upper lip. It can occur on the neck and forearms as well as other parts of the body prone to sun exposure. Melasma generally is worse in the summer and improves in winter. It can also appear during pregnancy or after starting birth control or other hormonal treatments. Visible light and heat often contribute to melasma spreading. Some dermatologists recommend using makeup with iron oxide to help block visible light.
Treatment
Hyperpigmentation can be treated using chemical peels or with a variety of over-the-counter products that contain skin brighteners such as vitamin C, kojic acid, niacinamide, hydroquinone, and azelaic acid. Melasma is more difficult to treat. Because melasma remedies that work for one person do not necessarily work for another, it is difficult to identify one effective treatment. Many dermatologists recommend a combination of sunscreen to protect the skin, brightening ingredients, and laser treatments for patients with melasma.
Melasma often responds to treatment with lasers in low energy, such as the Clear + Brilliant laser which uses low energy fractionated technology for melasma, sun damage, and skin texture. At least three treatments are needed monthly followed up by treatment every six months to maintain results. Talk with your dermatologist to determine the right plan for your skin.
Skin Protection
Always use sunscreen to protect your skin. Use a moisturizer with sunscreen and apply sunscreen with an SPF of 30 or higher every two hours when you plan to be in the sun or even inside sitting near a window. Hyperpigmentation and melasma can likely be avoided by incorporating sunscreen into your daily skin regimen.
