Melanin Offers Some Protection, But It’s Not Enough
Many people with darker skin tones assume they’re protected from the sun because of their melanin. While melanin does provide some natural defense against ultraviolet (UV) rays, dermatologists agree: it’s not enough on its own. Sunscreen is still necessary, and skipping it can lead to long-term damage like sunburns, dark spots, wrinkles, and increased risk of skin cancer.
“Everyone needs sunscreen. But the reasons that one might be reaching for sunscreen may differ depending on your skin tone,” said Dr. Jenna Lester, founder of the Skin of Color Clinic at the University of California, San Francisco.
Skin Cancer Risks Are Different — But Still Real
According to the American Cancer Society, white people are more likely to develop skin cancer overall, but Black and Hispanic patients are less likely to survive melanoma, the deadliest form. That’s because it’s often diagnosed too late. In darker-skinned individuals, melanoma often appears on the hands and feet, areas not typically exposed to sunlight, but sunscreen can still serve as an essential layer of protection.
“All of the problems that you’re coming to see me for are caused or worsened by the sun,” said Dr. Oyetewa Asempa, a dermatologist at Baylor College of Medicine, emphasizing that sunscreen helps prevent hyperpigmentation, rosacea, and dark patches that are common skin complaints in people of color.
The Right Way to Use Sunscreen for Darker Skin
For effective protection, dermatologists recommend using a broad-spectrum sunscreen with at least SPF 30. It should be reapplied every two hours, especially when outdoors or after swimming. Dr. Lester notes most people don’t use enough — you need two full finger-lengths of product for the face and a generous amount for the rest of the body.
To avoid the unwanted ashy white cast some sunscreens leave on darker skin, look for chemical-based formulas instead of mineral ones containing zinc oxide or titanium dioxide. Tinted sunscreens are also a great option — they blend better and provide extra protection against visible light, which can worsen dark spots.
Sunscreen Indoors? Absolutely.
Even inside, your skin isn’t totally safe. UV rays can penetrate through windows, meaning your skin is still exposed during car rides or when lounging near a sunny window at home.
“It’s about trying to make it a daily habit,” Dr. Lester said. “Consistency over intensity.”
Whether it’s for preventing cancer, evening skin tone, or just protecting your glow — sunscreen isn’t optional. It’s self-care.
