People with darker skin tones still need to wear sunscreen to prevent sunburn, dark spots, and wrinkles, as well as an increased risk of skin cancer. While melanin offers some extra protection from the sun, dermatologists say it’s not enough on its own.
Darker-skinned individuals are less likely to develop skin cancer than white people, but more likely to die from melanoma, a type of aggressive skin cancer. Sunscreen provides additional protection against other problems like hyperpigmentation, rosacea, and dark patches on the face.
To stay safe in the sun, apply sunscreen with an SPF of at least 30 every two hours, or immediately after swimming or sweating. Use chemical-free mineral-based products containing zinc oxide and titanium oxide for better coverage, and opt for tinted sunscreens for extra protection against dark spots.
Wearing a hat or protective clothing can also provide an added safety boost. Consistency is key when it comes to using sunscreen daily, even on cloudy days or indoors, as UV rays can still pass through windows.
