Skin Cancer Prevention Tips: What Works Beyond Sunscreen

Sunscreen is the first thing that comes to mind when people think about protecting their skin from cancer. While using a good sunscreen daily is important for reducing skin damage, there are a few additional ways to support your skin’s health and reduce your UV exposure.

This article explores those lesser-known prevention tools—what they can and can’t do—and how to talk with your care team before adding anything new to your routine.

Sun Exposure and UV Rays

Overexposure to ultraviolet (UV) rays, including UVA and UVB, can damage skin and increase your risk of developing skin cancer. These rays come from the sun and from tanning devices.

You can reduce your UV exposure with smart, everyday steps:

• Wear sunscreen with broad-spectrum protection.
• Cover up with hats and lightweight clothing.
• Stay in the shade when UV levels are highest.
• Avoid indoor tanning devices.

Sun safety is the foundation. From there, we can explore what diet and supplements may (or may not) add.

Diet and Supplements

Some nutrients and compounds may help support your skin’s response to UV damage, but they’re not substitutes for sunscreen. Here are four commonly discussed options:

• Beta carotene foods: Carrots, mangoes, and yellow bell peppers contain beta carotene, which your body can convert into vitamin A.
• Nicotinamide (niacinamide): A form of vitamin B3 available over the counter; ask your clinician before taking it daily.
• Green tea polyphenols: Compounds in green tea have been studied for potential antioxidant effects, though human results are mixed.
• Polypodium leucotomos: An antioxidant from a Central/South American fern that may help reduce UV effects when used alongside sunscreen.

If you’re considering supplements, talk with your care team to ensure they’re safe for you and used appropriately.

Alcohol and Skin Cancer Risk

Limiting alcohol intake is another step you can take to support overall cancer risk reduction. Alcohol use has been linked to a higher risk of developing several types of cancer, and some evidence suggests it may also be associated with a modestly higher risk of melanoma (a type of skin cancer).

Instead of focusing on daily drink limits, consider asking your clinician what limiting alcohol looks like for your specific health situation.
