Using sunscreen in a tanning bed will prevent the bronzing of your skin that you are after. In addition, sunscreen is only effective at blocking natural ultraviolet (UV) rays and not the artificial ones emitted by tanning bed bulbs, which are sometimes stronger (and more dangerous) than the sun.
This article reviews the risks of indoor tanning, including skin cancer and premature aging, the base tan myth, and proven sun protection strategies.
Skin Cancer Risks
The primary reason why using tanning beds, with or without sunscreen, is not advised is the risk of skin cancer. Research has repeatedly shown tanning beds are not safe. They increase the risk of skin cancer, particularly melanoma, a serious type of skin cancer that can be life-threatening.
Artificial tanning (including tanning beds, booths, and facial tanners) accounts for over 400,000 skin cancer cases in the United States each year. Over 6,000 of those cases are melanoma.
Premature Aging
Beyond increasing cancer risk, tanning beds also cause premature aging. Frequent UV exposure can cause brown spots, lax skin, photodamage, fine lines and wrinkles, and a leatherlike texture.
Unfortunately, human skin isn’t very forgiving when damaged by UV exposure, and it can only be corrected by cosmetic surgery. People who tan regularly, either in tanning beds or outdoors, can look much older than their peers who don’t tan.
The Mythical Base Tan
It is a common myth that getting a “base tan” before vacation will protect you from sunburn. The testimonies of travelers who frequent tropical destinations sound convincing, but they are more likely due to diligent sunscreen use rather than any preestablished tan.
When people are trying to establish a base tan to protect their skin, they are actually doing more harm than good—and they are often surprised when they still get sunburned afterward.
Proven Protection
To avoid burning, practice sun-safety procedures that have been proven effective in protecting the skin. Your first line of defense is to apply sunscreen when outdoors and apply it frequently. Avoid using a tanning bed entirely.
The American Society of Clinical Oncology (ASCO) recommends applying a sunscreen with a sun protection factor (SPF) of at least 30 before going outdoors. Higher SPF levels are available but offer only a minimal amount of increased protection.
Other sun-savvy tips include:
Wear a wide-brimmed hat to protect your face. Cover areas of exposed skin when you’re outdoors. Wear clothing with built-in SPF. Stay in the shade by sitting under an umbrella, awning, or other shady areas. Avoid midday sun, when the UV rays are more intense. Wear UV-protective sunglasses to shield your eyes.
Summary
Wearing sunscreen in a tanning bed prevents you from getting the bronze tan you are after. It also fails to protect your skin as it is only effective against natural UV rays. Tanning beds are not recommended because research repeatedly shows they are not safe. They can cause premature aging and skin cancer.
Some people feel that getting a “base tan” before sun exposure can help protect their skin. However, it is not effective against sunburn, and it is doing more damage than good. To avoid sunburn or sun damage, it’s best to use scientifically proven sun-safety techniques to help protect your skin.
A Word From Verywell
While tanning beds seem like a quick way to get a tan, they are not advised by medical professionals. The risk of skin cancer is too great, even with minimal use. Using sunscreen in a tanning bed will not protect you either.
Practice sun safety to protect your skin when outdoors, and consider wearing a topical bronzer or makeup.
