| Little heralds the arrival of summer like the smell of open water, smokey grills and sunscreen. | Little heralds the arrival of summer like the smell of open water, smokey grills and sunscreen. |
| Since the late 1970s, as medical researchers linked sun exposure to skin cancer, Americans have been told to dutifully slather, spray and rub on sunscreen as part of a broader package of sun protection. But does it make sense for me, a dark-skinned black woman, to wear it? | Since the late 1970s, as medical researchers linked sun exposure to skin cancer, Americans have been told to dutifully slather, spray and rub on sunscreen as part of a broader package of sun protection.

| With record-breaking heat this summer, it’s an especially relevant question, and you might even expect the answer to be “absolutely.” It’s more complicated than that. | With record-breaking heat this summer, it’s an especially relevant question, and you might even expect the answer to be “absolutely.” It’s more complicated than that. |
| The American Academy of Dermatology’s official position on sunscreen, which is echoed by the Food and Drug Administration, is that everyone, regardless of skin tone, should wear it because, “anyone can get skin cancer, regardless of age, gender or race.” But because people of color are often left out of clinical trials and treatments, there is very little research available about dark-skinned people and skin cancer, which raises questions about who is being considered when organizations make these public health recommendations. | The American Academy of Dermatology’s official position on sunscreen, which is echoed by the Food and Drug Administration, is that everyone, regardless of skin tone, should wear it because, “anyone can get skin cancer, regardless of age, gender or race.” But because people of color are often left out of clinical trials and treatments, there is very little research available about dark-skinned people and skin cancer, which raises questions about who is being considered when organizations make these public health recommendations. |
| Medicine, they say, is about balancing risks, and it turns out that the benefits and risks of wearing sunscreen when you have dark skin can be murky. Many experts believe that there is no clear link between sun exposure and skin cancer among people with dark skin, and there is also a growing body of research to suggest that using certain types of sunscreen may actually be harmful, no matter who uses it. | Medicine, they say, is about balancing risks, and it turns out that the benefits and risks of wearing sunscreen when you have dark skin can be murky.

| Now, let’s get some — ahem — burning questions out of the way. Black people experience sunburn that can be painful and cause peeling. When their skin is exposed to too much sunlight, black people can suffer from hyperpigmentation and visible signs of aging, just like people with other skin types. And, of course, black skin comes in a variety of shades, some of which are more sensitive to the sun than others. | Now, let’s get some — ahem — burning questions out of the way.

| The way skin researchers often quantify different skin tones is by using a subjective measure called the Fitzpatrick scale, which breaks skin tones into six categories based on color and how easily it tans versus burns when exposed to sunlight. Under the Fitzpatrick scale, I, a person who has never had a painful sunburn in her life, rate a six. | The way skin researchers often quantify different skin tones is by using a subjective measure called the Fitzpatrick scale, which breaks skin tones into six categories based on color and how easily it tans versus burns when exposed to sunlight.

| Dr. Martin Weinstock, a professor of dermatology and epidemiology at Brown University, was an author of a study in the Journal of the American Medical Association that looked at the relationship between ultraviolet light exposure, skin color and skin cancer, and found that while such a relationship exists among people with lighter skin tones, there’s no such relationship between sun exposure and skin cancer and dark-skinned individuals. | Dr. Martin Weinstock, a professor of dermatology and epidemiology at Brown University, was an author of a study in the Journal of the American Medical Association that looked at the relationship between ultraviolet light exposure, skin color and skin cancer, and found that while such a relationship exists among people with lighter skin tones, there’s no such relationship between sun exposure and skin cancer and dark-skinned individuals. |
| People whose skin is naturally brown when it has not been exposed to sunlight “are quite resistant to skin cancer,” Dr. Weinstock said. | |
| When dark-skinned people do get skin cancer, as Bob Marley famously did on his big toe, it tends to appear on “the palms of the hand and the sole of the feet,” said Dr. Adewole Adamson, a dermatologist and the director of the pigmented lesion clinic at The University of Texas at Austin’s Dell School of Medicine. | When dark-skinned people do get skin cancer, as Bob Marley famously did on his big toe, it tends to appear on “the palms of the hand and the sole of the feet,” said Dr. Adewole Adamson, a dermatologist and the director of the pigmented lesion clinic at The University of Texas at Austin’s Dell School of Medicine. |
| According to Dr. Adamson, the fact that dark-skinned people are most likely to get skin cancer on the areas of the body that are least likely to be exposed to sunlight suggests that this cancer is unrelated to sun exposure. | According to Dr. Adamson, the fact that dark-skinned people are most likely to get skin cancer on the areas of the body that are least likely to be exposed to sunlight suggests that this cancer is unrelated to sun exposure. |
| “If UV exposure was such a problem for skin cancer, you’d see a massive epidemic in sub-Saharan Africa,” he added. “They don’t have the same level of sunscreen promotion that they do here. And you hear nothing about it because there probably is no association.” | “If UV exposure was such a problem for skin cancer, you’d see a massive epidemic in sub-Saharan Africa,” he added. “They don’t have the same level of sunscreen promotion that they do here.

| Melanin is humankind’s inborn sunscreen. Everyone has melanin, but much like swagger, some of us have more of it. Melanin is also believed to delay the visible signs of aging. It’s why “black don’t crack.” | Melanin is humankind’s inborn sunscreen. Everyone has melanin, but much like swagger, some of us have more of it.

| Dark-skinned people don’t have more melanocytes, the cells that produce melanin, than lighter-skinned people. But the melanocytes that we do have tend to be more productive. And it’s because of melanin that some scientists believe darker skin tones absorb between 50 to 70 percent less of the sun’s ultraviolet light than paler skin tones. Exactly how much less is not well understood because fewer studies look at how darker skin reacts to the sun. | Dark-skinned people don’t have more melanocytes, the cells that produce melanin, than lighter-skinned people.

| This is not to say that dark-skinned people shouldn’t pay attention to their moles and get periodic skin checks — they should. Among dark-skinned people, skin cancer actually tends to be deadlier in part because it often goes undiagnosed for longer. It’s just that, according to these experts, the cause of that cancer isn’t necessarily the sun. | This is not to say that dark-skinned people shouldn’t pay attention to their moles and get periodic skin checks — they should.

| There are two broad categories of sunscreen. The first is mineral, which contains titanium dioxide or zinc. This type of sunscreen is considered safe by the F.D.A., as long it is not in powder form. It is also the type that black people tend to avoid because it often leaves a white residue on dark skin. | There are two broad categories of sunscreen.

| The second category is chemical. There is no consensus among scientists that the active ingredients in many chemical sunscreens, including oxybenzone, are safe. In fact, there’s new evidence to suggest that they may carry their own health risks. | The second category is chemical.

| A pilot study that the F.D.A. released earlier this year in the Journal of American Medical Academy caused a stir because it found that when participants applied a day’s worth of common sunscreens, they not only absorbed its chemicals but did so at levels that exceeded a target F.D.A. toxicology threshold. | A pilot study that the F.D.A. released earlier this year in the Journal of American Medical Academy caused a stir because it found that when participants applied a day’s worth of common sunscreens, they not only absorbed its chemicals but did so at levels that exceeded a target F.D.A. toxicology threshold. |
| That these chemicals are absorbed into the skin at such high concentrations doesn’t mean they’re inherently dangerous, but it does mean that they need to be studied for biological effects. | |
| “Although over-the-counter sunscreen products are widely used, little is known about systemic exposure for most active ingredients,” the F.D.A. said in a written statement. | “Although over-the-counter sunscreen products are widely used, little is known about systemic exposure for most active ingredients,” the F.D.A. said in a written statement. |

| Dr. Kannan’s study found that women who used more sunscreen that contained benzophenone or oxybenzone, two estrogenic compounds, had higher levels of the chemicals in their urine, and had higher rates of endometriosis. Dr. Kannan said he considers chemical sunscreen use something of a double-edged sword. It potentially provides protection from skin cancer, but it can also affect estrogen levels, which could lead to a variety of diseases. | Dr. Kannan’s study found that women who used more sunscreen that contained benzophenone or oxybenzone, two estrogenic compounds, had higher levels of the chemicals in their urine, and had higher rates of endometriosis.

| These findings are part of why Dr. Adamson thinks there needs to be more discussion around the particular risks and benefits of wearing sunscreen, especially for people with dark skin. | These findings are part of why Dr. Adamson thinks there needs to be more discussion around the particular risks and benefits of wearing sunscreen, especially for people with dark skin. |
