The Dangers of "Tanmaxxing"

Hi everyone, I'm Dr.

Jane Yoo, board-certified dermatologist and Mohs surgeon. Tan maxing is trending.

The idea is that a deep, dark tan is a beauty goal worth chasing at any cost. But as a board-certified dermatologist and Mohs surgeon, I need you to see what I see every day. The skin cancers, the leathery premature aging, or the patients who wish that they'd known about this in their 20s. Let's talk about what tan maxing is actually doing to your skin and why there's no such thing as a healthy tan.

So what exactly is tan maxing? It's the idea spreading across social media of deliberately maximizing your time in the sun to get the deepest tan possible. Baby oil instead of sunscreen, tanning bed sessions stacked back to back, skipping SPF entirely because people think it'll let the tan soak in faster, even reflective tanning mats to bounce more UV onto your skin. It's being framed like a wellness optimization, almost as if a deeper tan automatically means a better Better looking, healthier appearance. And underneath all of it is the same core myth: that a tan is a sign of health. It's not. Here's what's actually happening under your skin when you tan. A tan is your skin's SOS signal. Your melanocytes are producing more pigment to shield your DNA from further damage. That's a defense response, not a glow-up. UVA rays penetrate deeply into the dermis where they break down collagen and elastin, which is what drives photoaging. Photoaging, the wrinkles and sagging you'll see later. UVB rays do something even more concerning. They damage the DNA inside your keratinocytes directly, and that's exactly where mutations start. So every single tan you get represents a measurable increase in cumulative UV-induced DNA damage, and it doesn't matter whether the UV comes from the sun or from a tanning bed. Your skin doesn't know the difference.

Let's start with the biggest one, skin cancer. Using a tanning bed before age 35 significantly increases your risk of melanoma. And more broadly, cumulative UV exposure is the single biggest modifiable risk factor for basal cell carcinoma, squamous cell carcinoma, and melanoma, the 3 most common types of skin cancer that I see. I want to be direct with you here. As a Mohs surgeon, I remove skin cancers every single week from patients who tanned intentionally in their teens and 20s. This isn't a hypothetical risk. It's what's sitting on my surgical schedule. Beyond cancer, there's photoaging— wrinkles, leathery texture, uneven pigmentation, and broken capillaries. UV exposure is responsible for the vast majority of visible aging you'll see in your skin over your lifetime. Which is far more than the simple passage of time itself. What looks bronzed and glowing at 22 often shows up as deep static wrinkles and solar lentigines, those dark sunspots, by the time you're 35 to 40. Tan maxing also worsens melasma and sunspots, and once those set in, they can be very difficult to treat. There's a real irony here because people chasing an even deep tan often end up with uneven, hard-to-correct pigmentation instead. And I have to address this myth directly because I hear it constantly. The idea that you should get a base tan before a vacation to protect your skin. A base tan gives you the UV protection equivalent of roughly SPF 3 to 4, nowhere close to adequate. It won't stop you from burning, and it does absolutely nothing to offset the DNA damage that's already occurring while you build that base. So what should you be actually doing? Wear broad-spectrum SPF 30 or higher every day and reapply every 2 hours Add an antioxidant serum like vitamin C to your morning routine to help combat UV-induced oxidative stress. Wear protective clothing and seek shade during peak UV hours, roughly 10 AM to 4 PM. And if you want that bronze look, self-tanners and tinted SPF products will give you color without DNA damage. That's generally the safer way to get the look that you're going after. And get a skin check, especially if you have a history of cancer or if you're concerned about premature aging. tanning bed use, a history of sunburns, or a family history of skin cancer. A tan fades in weeks. The damage underneath it doesn't. If you take one thing away from this video, let it be this: the glow trend isn't worth trading for your skin's long-term health. And there are other ways to get that bronze look without UV exposure.
