Skin cancer remains the most common form of cancer in the United States, with more than 9,500 people diagnosed every single day. But new research is offering hope in the fight against the disease. In an interview with NBC Palm Springs, morning anchor and investigative reporter Mary Strong spoke with Beverly Hills board-certified dermatologist Dr. Jacquiline Hakim about an emerging tool in skin cancer prevention: Vitamin B3.
Also known as niacinamide, Vitamin B3 is gaining attention for its potential to help the skin repair itself after damage caused by ultraviolet (UV) exposure. According to recent studies, the vitamin supports DNA repair and strengthens the skin’s immune response—two key factors in preventing certain types of skin cancer.
“Traditionally, we’ve relied heavily on sunscreen as our first line of defense,” Dr. Hakim explained. “But now we’re learning that Vitamin B3 may play an important supporting role, particularly when it comes to non-melanoma skin cancers.”
Non-melanoma skin cancers, which include basal cell and squamous cell carcinomas, are the most common forms of the disease. While melanoma is less common, it is more aggressive and deadly—something researchers are still working to better understand in relation to Vitamin B3’s effectiveness.
Dr. Hakim says niacinamide can be found both in topical creams and oral supplements, but the form and dosage matter. “There’s ongoing research into how much is needed and whether it should be taken daily,” she said, noting that people should always consult with a healthcare provider before starting any new supplement regimen.
Despite growing awareness around sun safety, skin cancer rates continue to climb. Experts say that inconsistent sunscreen use, increased sun exposure, and tanning habits all contribute to the trend. With summer just around the corner, Dr. Hakim emphasizes the importance of a multi-layered approach to protection. That includes wearing broad-spectrum sunscreen, seeking shade during peak sun hours, wearing protective clothing, and considering emerging options like Vitamin B3 as part of a broader prevention strategy. “Prevention is always better than treatment,” Dr. Hakim said. “The more tools we have, the better we can protect ourselves.”
