Buying guide for best broad-spectrum sunscreens

Whether you have dark or fair skin and regardless of your age, you should be using a sunscreen every day that protects you from the sun’s damaging rays.

There are two types of ultraviolet light from the sun that can damage your skin and cause skin cancer: long-wave ultraviolet A (UVA) rays, which penetrate skin more deeply and cause aging and wrinkling, and short-wave ultraviolet B (UVB) rays, which tend to cause sunburns. Both play a role in causing skin cancer. Broad-spectrum, also called full-spectrum, sunscreens protect you from UVA and UVB. They do this either by reflecting the sun’s rays or absorbing the light and converting it into a small amount of heat. Like regular sunscreens, broad- spectrum sunscreens have a sun-protection factor (SPF), which is an indicator of how long the product will protect you from UVB rays, and it can range from quite low (15) to ultrahigh (100).

There are numerous other considerations when choosing a broad-spectrum sunscreen: organic versus inorganic, your individual skin type, water/sweat resistance and environmental concerns, such as whether you’ll need a product that is reef-safe. It’s worth taking the time to understand how broad-spectrum sunscreens work and what they have to offer. Keep reading our guide for more information.

UVA and UVB rays are present in the atmosphere at all times. What’s the difference between them?

UVA rays from the sun can reach a person’s skin through glass, so you’re getting exposure even if you’re sitting in a car or working near a window. The exposure over a lifetime is significant and can contribute to the development of skin cancer. Tanning beds and lamps also emit high concentrations of UVA light.

UVB rays from the sun are more prone to cause a sunburn. They are strongly associated with the risk of developing skin cancer. They are present all year long, though more intense in the spring through the early fall months in the U.S. The SPF of a sunscreen is rated for how well it protects your skin from this type of ultraviolet light.

Though UVA protection isn’t rated, a broad-spectrum or full-spectrum sunscreen will protect you from both UVA and UVB rays.

Organic vs. inorganic

A consideration for selecting a broad-spectrum sunscreen is whether it works by way of chemical ingredients or by creating a physical barrier. These two types of sunscreens are also referred to as organic and inorganic.

Organic Organic broad-spectrum sunscreens use chemicals such as PABA derivatives, oxybenzone, avobenzone, and octinoxate to absorb radiation from the sun and convert it into heat.

Inorganic Inorganic broad-spectrum sunscreens provide a physical barrier of zinc oxide and/or titanium dioxide to reflect the sun’s ray. These tend to be more difficult to rub in and may leave some white residue.

Adding a layer of confusion, some sunscreens are labeled “organic” because their ingredient list contains natural, non-toxic ingredients when, in fact, these use “inorganic” zinc oxide and titanium dioxide for sun protection rather than chemicals.

All sunscreens, broad-spectrum or not, have an SPF. This number is a relative measurement of how well a sunscreen will protect against UVB rays. We tend to think of it in terms of time, or how long it takes to redden/burn skin wearing that SPF level versus the amount of time it would take to burn without it. For example, if your skin would normally burn after ten minutes of unprotected exposure to the sun, an SPF of 30 should provide 300 minutes (or five hours) of protection.

However (and this is where it gets tricky), there are other factors that enter into the equation, including weather conditions, time of day, skin type, thoroughness of application and more, so you should not assume that with SPF 30, you can safely remain in the sun for five hours. Furthermore, all sunscreens lose their effectiveness over time and must be reapplied every two hours.

An SPF of 30 protects you from 97 percent of UVB rays whereas an SPF of 50 protects you from 98 percent. There is no sunscreen that will protect you from 100 percent of UVB rays, though an SPF of 100 will protect you from 99 percent.

If you don’t apply the sunscreen thickly or thoroughly enough — about one full ounce or roughly a shot glass worth for an average adult — or if you sweat or go swimming, the SPF protection will be weakened, so you should reapply immediately after swimming or heavy sweating.

Features

Water resistant: Don’t assume your broad-spectrum sunscreen will protect you when you’re swimming or sweating. Although sunscreens are no longer designated “waterproof”, only those designated “water resistant” will maintain effectiveness while you swim or sweat (for up to 40 minutes). Those designated “very water resistant” will work for up to 80 minutes.

Reef safe: When you swim in the ocean, a fair amount of sunscreen ends up in the water. Environmentally friendly sunscreens don’t have chemicals (like oxybenzone or octinoxate) that have been proven to damage reefs. Some places with coral reefs, like Hawaii, have banned the sale of sunscreens containing these ingredients.

Spray: A great feature for people with limited mobility or who are traveling solo to the beach or pool is spray sunscreen to hit those hard-to-reach places. Parents often prefer sprays because they’re easier to apply to children. Be sure to apply an even coat, and avoid inhaling the product.

Lightweight: If you have oily skin, you may want to avoid moisturizing or creamy sunscreens. Many broad-spectrum sunscreens offer non-greasy formulas that absorb easily into your skin, often leaving a matte or dry-touch finish. Select ones that are non-comedogenic if you have acne-prone skin, as these won’t clog your pores.

Sensitive skin: If you have sensitive skin, select a product that’s labeled hypoallergenic and fragrance free. You may also benefit from a product free from parabens and other chemical agents.

Face: There are also broad-spectrum sunscreens formulated specifically for the more delicate face area. These tend to be oil-free and pricier, but are good for sensitive skin as body sunscreens may cause irritation on the face.

Tips on applying sunscreen

Broad-spectrum sunscreen is only effective if it’s applied properly.

Put on sunscreen 15 minutes before you step outside. It takes 15 minutes for it to absorb into your skin and protect you.

Apply sunscreen generously. Most people don’t put on enough. For adults, this means one ounce to cover your whole body. Be sure to rub it in thoroughly.

Cover all exposed areas. Don’t forget the back of your hands, bald spots, tops of your feet, back of your neck, lips, ears, etc. Ask for help in those hard-to- reach areas.

Reapply sunscreen every two hours or immediately after you swim or sweat, even if you’re using a water-resistant product. The majority of sunburns happen because of failure to reapply.

Apply sunscreen even when it’s cloudy out. UVA and UVB rays can pass through clouds. Use sunscreen all year. Sun reflected off of snow can be even stronger and likely to cause sunburns.

Check the expiration date of your sunscreen, and never apply an expired product. Sunscreen is effective no more than three years after its manufactured date. Also, store sunscreen away from heat as it will degrade the product.

FAQ

Q. Can I put a broad-spectrum sunscreen on my baby? A. Sunscreen is not considered safe for infants under 6 months old. Keep your baby in the shade as much as possible when outdoors. For children aged 6 months and older, it’s best to use a broad-spectrum sunscreen formulated for children. These tend to contain titanium dioxide and/or zinc oxide which is considered safer and less irritating to young skin.

Q. Do I need to apply sunscreen to my face if I use cosmetics that have sunscreen? A. Many foundations, powders, moisturizers and the like these days contain SPF-rated sunscreen. If you’re not spending a lot of time outdoors these should be sufficient. Be aware, however, that these may only protect you from UVB rays and not UVA. Opt for products containing full-spectrum protection or apply a broad-spectrum sunscreen under your makeup.

Q. Do I really need to use a broad-spectrum sunscreen all year round? A. Yes. UVA and UVB rays can penetrate through cloud cover. Also keep in mind that UVA rays can go through glass, so even if you don’t spend much time outdoors you’re probably still exposed to UVA rays. If you don’t want to slather on sunscreen every day, try a combination of clothing that covers exposed skin and a wide- brimmed hat. Also, some clothing carries an ultraviolet protection factor (UPF) comparable to an SPF. For instance, an article of clothing may have a UPF rating of 30, protecting you from all but 1/30th of the sun’s rays. Remember, even a high SPF, full-spectrum sunscreen won’t protect you 100 percent, so other precautionary measures are advisable, such as avoiding the sun between the peak hours of 10 a.m. and 2 p.m, year round.
