Sunscreen Myths That Need to Retire

If you've spent any time on social media lately, you've probably seen someone passionately arguing that sunscreen is poisoning us, causing cancer, destroying coral reefs, disrupting hormones, or somehow making us less healthy than simply letting the sun do its thing.

Meanwhile, skin cancer remains the most common cancer in the United States.

Somewhere between the fear-mongering and the marketing, we've lost the plot.

At Holladay Spa, we're big believers in helping you make informed decisions—not fearful ones. So let's clear up some of the biggest sunscreen myths floating around the internet and talk about what the science actually says.

Myth #1: Sunscreen Is "Toxic"

Let's start with the word that gets thrown around more than any other: toxic.

The problem is that "toxic" has become a buzzword that often means nothing.

Water is toxic in high enough amounts.

Vitamin A is toxic in high enough amounts.

Even oxygen can be toxic under certain circumstances.

The real question isn't whether something is capable of causing harm. The question is whether it causes harm at the dose we're exposed to in real life.

In the United States, sunscreen ingredients are regulated as over-the-counter drugs by the FDA. That means they undergo significantly more scrutiny than most skincare products.

Does that mean every ingredient is perfect?

Of course not.

Science is always evolving, and researchers continue to study sunscreen ingredients just like they study medications, food additives, and countless other products we use every day.

But there is a huge difference between "scientists are continuing to study this" and "this product is toxic."

Those are not the same thing.

Myth #2: Mineral Sunscreens Are Safer Than Chemical Sunscreens

This is probably the most common sunscreen myth we hear.

The internet often paints mineral sunscreens as natural and safe while portraying chemical sunscreens as dangerous chemicals that soak into your bloodstream.

Reality is a little more nuanced.

First, everything is made of chemicals—including water, oxygen, and zinc oxide.

Second, both mineral and chemical sunscreens are designed to protect your skin from ultraviolet radiation. They simply use different active ingredients to accomplish the same goal.

For years, people were taught that mineral sunscreens sit on top of the skin and reflect UV rays like tiny mirrors while chemical sunscreens absorb UV rays.

While there is a grain of truth there, modern research shows that both types actually work primarily by absorbing and dispersing UV energy as heat before it can damage skin cells.

In other words, they are far more similar than they are different.

The best sunscreen isn't automatically mineral.

The best sunscreen isn't automatically chemical.

The best sunscreen is the one that you will happily wear every single day.

Myth #3: If an Ingredient Is Found in the Bloodstream, It Must Be Dangerous

This is another misunderstanding that spreads quickly online.

Modern laboratory testing is incredibly sensitive. Scientists can detect extraordinarily tiny amounts of substances in the bloodstream.

Finding something in the bloodstream does not automatically mean it is harmful.

Researchers have detected caffeine, medications, skincare ingredients, and countless other compounds in the bloodstream.

The important question is whether the amount present is high enough to cause harm.

Many viral headlines stop at "detected in the blood" and never get to the much more important question of whether that level is actually dangerous.

Detection does not equal danger.

Myth #4: Chemical Sunscreens Are Destroying Coral Reefs

This topic gets emotional quickly because most people genuinely care about protecting the environment.

The concern stems from laboratory studies showing that extremely high concentrations of certain sunscreen ingredients can negatively impact coral under controlled conditions.

What often gets left out of the conversation is that these concentrations are frequently much higher than what is found in natural ocean environments.

Meanwhile, coral scientists overwhelmingly identify rising ocean temperatures as the primary driver of coral bleaching worldwide.

Coral bleaching occurs when prolonged heat stress causes corals to expel the algae they depend on for survival.

In other words, climate change is not a side issue in coral bleaching—it is the main issue.

That doesn't mean we shouldn't continue researching sunscreen's environmental impact.

We should.

But blaming coral bleaching primarily on sunscreen oversimplifies a much larger environmental problem.

Myth #5: Mineral Sunscreens Are Automatically Better for the Environment

This is where the conversation gets interesting.

Many people assume mineral sunscreens are environmentally harmless because they contain zinc oxide or titanium dioxide.

What rarely gets discussed is where those ingredients come from.

Zinc and titanium don't magically appear in sunscreen bottles.

They must be mined.

Mining requires land disturbance, energy consumption, water use, transportation, processing, and waste management. Like virtually every industrial process, it carries environmental costs.

This doesn't make mineral sunscreens bad.

But it does highlight an important reality:

Environmental decisions are rarely as simple as "this one is good" and "that one is bad."

Every product we use has tradeoffs.

The Risk We Don't Talk About Enough

While social media debates sunscreen ingredients, one risk often gets overlooked entirely:

UV damage.

Ultraviolet radiation is a known carcinogen.

It contributes to skin cancer, premature aging, pigmentation, collagen breakdown, and many of the skin concerns people spend years trying to reverse.

No sunscreen is perfect.

No skincare product is perfect.

But the evidence supporting protection from excessive UV exposure is overwhelming.

That's why dermatologists, oncologists, and skin cancer researchers continue to recommend daily sun protection.

So What Sunscreen Should You Use?

The answer is refreshingly simple.

Use the sunscreen you'll actually wear.

Every day.

If you love a mineral sunscreen, wear it.

If you love a chemical sunscreen, wear it.

If you prefer a hybrid formula, wear it.

Consistency matters more than perfection.

Because the world's most "perfect" sunscreen doesn't protect your skin if it's sitting in a drawer because you hate how it feels.

At Holladay Spa, we're less interested in sunscreen debates and more interested in helping you build habits that support healthy skin for the long haul.

The goal isn't perfection.

The goal is protection.

And the best sunscreen is still the one that's on your face.
