DVIDS – News – Doctors recommend sunscreen for all skin tones

People with darker skin or skin color are sometimes less likely to use sunscreen and protect themselves from excessive sunlight, according to dermatologists.

But the dangers of too much sun exposure – from sun spots to skin cancer – are real risks for everyone, regardless of skin tone, doctors say.

Research shows that melanin, the natural pigments that affect skin tone, provide some natural protection against the risk of skin cancers caused by the sun’s ultraviolet rays.

But everyone, regardless of skin tone, is always at risk for sun-related skin cancers.

And aside from cancer, some other sun exposure risks and potential skin problems are actually more common in people with darker skin.

“Most important to me, and to my patients skin of color, is the increased risk of pigmentation issues,” the Navy Lt. Commander said. (Dr.) James Contestable, dermatologist at Camp LejeuneNaval Medical Center Camp Lejeune on the TRICARE Naval Medical Center, North Carolina website.

“Post-Inflammatory Hyperpigmentation, Dark Spots, and MelasmaMelasma on the NIH website are more common in skin of color. For this reason, I recommend high-grade zinc oxides, iron oxides (found in tinted sunscreens) and sunscreens that contain antioxidants and free radical quenchers,” he said.

According to the National Institutes of Health, the hyperpigmentation page on the cancer.gov website is one of the most common reasons dark-skinned people see a dermatologist.

According to experts, the ultraviolet and infrared rays of the sun are essential to aggravate melasma.

“The role of UVA and visible spectrum light in the development of pigmentation problems has been highlighted over the past decade,” Contestable noted.

“Zinc offers broad UVA protection and iron oxides offer good protection against visible spectrum light. Finally, tinted sunscreens offer the added benefit of avoiding the dreaded pasty white cast that can reduce adhesion. to sunscreens, especially in the skin of people of color,” he commented. .

Contestable recommends using sunscreens that contain both a clear “chemical” sunscreen and a “physical” broad-spectrum UV blocker like zinc oxide because of their “synergistic effect.”


A recent study published in the Journal of the American Academy of Dermatology found that people with darker complexions are less likely to use sunscreens and practice other behaviors despite sunburn, which can be a precursor to sunburn. skin cancer.

According to experts, there are persistent misconceptions about the need for people with skin color to use sunscreen daily and to stay out of the sun and wear protective clothing.

Some people with colored skin are unaware of the need for photoprotection to protect against skin cancer due to the belief that their naturally dark complexion is more capable of providing protection against skin damage caused by sun exposure, the study suggests.
Use sunscreen daily

Some people who have desk jobs don’t feel like they need to use sunscreen or sunscreen daily because they don’t get much sun exposure.

Contestable’s answer to this? “UVA and visible light pass through windows. Visible light is produced by our indoor lighting devices, including computer monitors and cell phones. Therefore, sunscreen always has a role to play. even play indoors.”

“This is particularly important in those who suffer from pigmentary disorders such as melasma or post-inflammatory hyperpigmentation.”

“I also say, ‘How did you get to work? You usually have to walk from the car to the office, and every sunscreen helps.”

FPS level?

Contestable said he thinks the target SPF level “should be the same for all skin types.”

“There’s a hotly debated question” about sunscreens with higher SPFs, Contestable said.

“Some experts will say that SPF 30 blocks 97% of UVB rays, ‘so why use a higher SPF?’ Their opinion is that with a higher SPF there is less overall gain because SPF 50 blocks 98% of UVB rays and SPF 100 blocks 99%,” he said.

For patients of all skin tones, Contestable recommends an SPF of 30 to an SPF of 100 because “it doesn’t cost much more to get a higher SPF.”

Second, “in the real world, we know that most people only apply 25-50% of the amount of sunscreen needed to meet the SPF on the label. Hopefully if someone applies half from the amount of SPF 50, it can reach an SPF of 25, and some research supports this linear relationship.”

Most people should just find a sunscreen they like and will use! People with skin conditions or specific skin conditions should get a personalized sunscreen and sun protection plan from their dermatologist, recommends Contestable.

Sun exposure tips

Here are the Centers for Disease Control and Prevention’s sunscreen use and sun exposure recommendations that apply to people of all skin colors.

Use sunscreen or sunscreens daily
Apply 15 minutes before going outside so that the product can be absorbed by the skin
Stay out of the sun as much as possible
When out in the sun, wear a wide-brimmed hat, long-sleeved shirt, long pants, and sunglasses
Use products with SPF 15 or higher
Make sure the product label says Broad Spectrum and Water Resistant
Half a teaspoon is enough to cover the face and neck, or an arm. One ounce — about the size of a full shot glass — is recommended for full body coverage, so a six-ounce bottle won’t last long
Reapply at least every two hours and after any exposure to water, regardless of SPF.
