We frequently see patients who used tanning beds in their teens or twenties and now face early skin cancers or significant photoaging. The desire for a quick, even tan is understandable—especially before events or during long Minnesota winters—but the science on indoor tanning is clear and concerning.
Tanning beds and sunlamps emit concentrated ultraviolet radiation, primarily UVA with some UVB, often at intensities that can exceed midday summer sun. The World Health Organization classifies these devices as Group 1 carcinogens, the same category as tobacco and asbestos. Multiple large studies and analyses show that indoor tanning significantly increases the risk of melanoma, the most serious form of skin cancer.
What the Research Shows About Risk
Key findings include:
- Using tanning beds before age 20 can increase melanoma risk by about 47 percent, and the risk rises with each additional use.
- Indoor tanning can more than double the overall risk of melanoma.
- Women younger than 30 who tan indoors are approximately six times more likely to develop melanoma than those who do not.
- Indoor tanning also raises the risk of the more common non-melanoma skin cancers—basal cell carcinoma by roughly 24 percent and squamous cell carcinoma by about 58 percent.
Recent research has further documented higher rates of DNA mutations in the pigment-producing cells (melanocytes) of people who use tanning beds, including in areas of skin not typically exposed to outdoor sunlight. Melanomas linked to indoor tanning also tend to occur at younger ages.
A tan itself is evidence of DNA damage in the skin. There is no such thing as a “safe” or “protective” base tan from UV sources. The damage is cumulative and irreversible.
Why Tanning Beds Are Particularly Harmful
Unlike gradual outdoor exposure, tanning beds deliver high-intensity UV in a short, controlled session. This concentrated dose causes more widespread DNA injury. The American Academy of Dermatology opposes indoor tanning for non-medical purposes precisely because the evidence of harm is strong and the exposure is entirely avoidable.
In addition to raising cancer risk, repeated indoor tanning accelerates wrinkles, loss of firmness, uneven pigmentation, and other signs of photoaging—changes we see frequently in patients who used beds regularly in their younger years.
Safer Alternatives for a Glow
Excellent options exist that do not involve UV damage:
- High-quality self-tanners and gradual-build lotions applied at home. St Tropez is a great option that offers self-tanning serums, mousse and lotions.
- Professional spray tans for a more even, longer-lasting result.
- Tinted moisturizers or bronzing products for subtle, controllable color. The Intellishade family of products by Revision Skincare is a fan favorite or stop by AST to check out matte and shimmer bronzers by Jane Iredale Mineral Makeup.
- Consistent daily broad-spectrum SPF 30 or higher, protective clothing, and shade to preserve the healthy skin you already have.
These approaches deliver the look many people want without the DNA damage or long-term cancer risk.
What to Do If You Have a History of Indoor Tanning
If you used tanning beds in the past, it is never too late to protect your skin going forward. Schedule a full-body skin examination so we can assess moles, document any changes, and create a personalized monitoring plan. Regular skin checks are especially important for anyone with a history of indoor tanning, multiple sunburns, or family history of melanoma.
The Bottom Line
Indoor tanning is a preventable risk factor for melanoma and other skin cancers. The temporary glow is not worth the lasting damage. By choosing UV-free alternatives and practicing consistent sun protection, you support healthier skin for decades to come.
