Scroll through your feed in the summer, and you’ll spot it: beach selfies, “tanning hacks,” and creators showing off their glow. But a tan isn’t a beauty boost; it’s often a sign of damage.
Your skin doesn’t interpret a tan the way Instagram does. Instead, it sees a tan as a response to injury.
Whether it comes from the sun or a tanning bed, a tan develops when ultraviolet (UV) radiation damages the skin, triggering increased melanin production as a protective response. There is no such thing as a safe tan. That’s why healthcare providers are paying attention to “tan-fluencing,” the growing wave of social media content that promotes tanning while glossing over the associated risks.
What’s Actually Happening When You Tan
When UV rays hit your skin, your body shifts into defense mode and produces more melanin, the pigment that gives skin its color. It may seem like your body is adapting, but in reality, your skin is responding to damage that has already occurred. According to the CDC, any change in skin color after UV exposure, whether a tan or a sunburn, is a sign of skin injury, not health.
And you don’t need a sunburn for the damage to accumulate. Even skin that tans easily experiences UV damage, and that damage adds up over time.
“We focus on prevention as much as treatment. That means helping patients understand their individual skin cancer risk, teaching practical sun-protection habits, and encouraging regular skin checks so that any concerning changes can be identified as early as possible.”

What That Glow Can Cost You
Most of us think about tanning in terms of how we look today. The bigger story is what UV exposure can do to your skin over time:
- Skin cancer. UV radiation damages the DNA in skin cells, increasing the risk of skin cancer, including melanoma, the deadliest form. The American Academy of Dermatology reports that using tanning beds before age 20 can increase melanoma risk by 47%, with the risk rising with each use.
- Faster aging. The Environmental Protection Agency notes that up to 90% of the visible skin changes people attribute to aging are actually caused by the sun. Think fine lines, wrinkles, age spots, and uneven texture, often appearing years earlier than expected.
- Eye damage. The EPA also notes that UV radiation increases the risk of certain cataracts, a clouding of the eye’s lens that can lead to vision loss if left untreated. Your sunglasses are doing more than completing your outfit, they’re helping protect your eyes.
The Myths Worth Busting
A few tanning myths just won’t die. Here’s where they fall apart:
- “A base tan protects me.” A base tan provides roughly the equivalent of SPF of 3. That’s essentially no meaningful protection once you’re in the sun, and you can still burn.
- “I need to tan for vitamin D.” Tanning beds primarily emit UVA rays, which do little to boost vitamin D levels. Food, supplements, and everyday sun exposure can help you get what you need.
- “Darker skin doesn’t need sunscreen.” More melanin does provide some natural protection, but skin cancer affects people of all skin tones.
- “Tanning beds are safer than the sun.” They’re not. A major review by the International Agency for Research on Cancer found that first using a tanning bed before age 35 was associated with a 75% higher risk of melanoma. The same agency classifies tanning devices as carcinogenic to humans, alongside tobacco and asbestos.
Want the Look Without the Risk?
Love the bronzed glow? You don’t have to choose between your look and your skin health. Self-tanners, bronzing drops, and spray tans can give you that color without UV exposure. The results fade, but so does a real tan, without increasing your cancer risk or accelerating aging.
How to Enjoy the Sun Safely
You don’t have to stay indoors to protect your skin. A few simple habits can go a long way:
- Wear broad-spectrum sunscreen with SPF 30 or higher and reapply every two hours.
- Add a hat, sunglasses, and protective clothing whenever possible.
- Seek shade during peak UV hours, generally between 10 a.m. to 4 p.m.
- Check your skin regularly for new or changing moles and spots.
Trends come and go. Your skin is with you for life, so treat it that way.
