Sunscreen Used to be a chore

Think about sunscreen for a second. For most people, it was never a pleasurable product. That grayish film that left your face a shade or two lighter than your neck. The greasiness. The heavy, tacky reminder all day long that you were wearing it. A seasonal item you grabbed once a summer on the way to the beach. In a word: a chore.

And yet, over the last few years, sunscreen has increasingly become part of Americans' everyday skincare routines — especially among younger consumers. Social media has helped normalize daily SPF use, while the rise of K-beauty has pushed facial sunscreen toward lighter, more skincare-like formats. That shift happened alongside a much bigger K-beauty boom. In 2025, U.S. sales of Korean beauty reached roughly $2 billion, up 37% year over year. Much of K-beauty's growth has happened online, with TikTok Shop emerging as an important discovery and launch channel alongside platforms and retailers like Amazon, Sephora, and Ulta. (NielsenIQ, via CNBC).

Which raises a genuinely interesting question: how do you sell sunscreen — arguably one of the most boring products in skincare?

Half the answer is the product itself. Korea regulates sunscreen as a "functional cosmetic," under a different regulatory framework from the U.S., where sunscreen actives have historically been regulated as over-the-counter drugs. That difference gave Korean formulators access to UV filters that, for years, weren't available to U.S. brands — the raw material behind high-SPF formulas that spread on like water and don't leave a white cast.

The result wasn't simply "better sunscreen." Korean brands became especially good at making high-SPF products feel like skincare: lightweight textures, less visible residue, serum-like finishes, and formulas designed to sit comfortably under makeup — cracking the "chalky sunscreen" problem that Western SPF failed to solve for over a decade. The U.S. is beginning to catch up. In June 2026, the FDA added bemotrizinol to its permitted sunscreen actives — the first new ingredient added to the OTC sunscreen monograph since the late 1990s. But by then, K-beauty had already spent years building a reputation around a different sunscreen experience. And product alone doesn't explain why certain Korean sunscreens took over America while dozens of equally good formulas didn't.

The other half — and the real subject of this piece — is marketing. Plenty of sunscreens have great textures; only some become products that thousands of consumers voluntarily talk about. What separated the winners from the rest wasn't the formula. It was how they sold it.

And that "how" is now something you can actually see. Using a social-listening tool like Exolyt to map which hashtags repeatedly appear together on TikTok — and analyze what people say in comments — you can compare what a brand wants consumers to believe with what consumers actually repeat.

That's where things get interesting. Let's follow that conversation.

One — They Sell a Feeling, Not Protection

Traditional sunscreen advertising always said the same thing: "SPF 50." "Broad spectrum." "UV protection." In other words, it sold how well the product protects you. Korean brands changed the frame. Protection became the baseline; the real selling point became what sunscreen does for your skin — and how it feels to wear.

You can see that shift directly in the TikTok conversation. Map #sunscreen in Exolyt by hashtag co-occurrence, and #spf and #spf50 are still there. But one of the biggest nodes surrounding the category is #skincare, surrounded by tags like #koreanskincare, #kbeauty, #skincareroutine, #sunscreenserum, #glowup, and #nowhitecastsunscreen.

That tells you where the category has moved.

• SPF has become table stakes. Consumers still care about protection, but SPF 50 is no longer a compelling story on its own.
• Sunscreen is now skincare. It is talked about alongside routines, serums, pigmentation, glow, and other skincare concerns — not as a separate beach product.
• K-beauty is shaping the category itself. #koreanskincare, #kbeauty, #koreansunscreen, and brands like Round Lab and Skin1004 sit directly inside the broader sunscreen conversation.
• Texture and finish have become part of the performance. #sunscreenserum, #nowhitecastsunscreen, and #glowup show that people judge sunscreen not only by what it blocks, but by how it applies, looks, and feels.

The sunscreen conversation has moved from "How strong is the protection?" to "Will I actually want to put this on my face every day?" And Korean brands were built for exactly that question.

Lesson one: once function becomes a baseline, sell the experience.

Two — They Build Proof, Not Ads

The second difference is the shape of the content. Traditional brands make ads — models, studios, copy. Korean sunscreen brands make visible proof instead.

face, applies a Western sunscreen on one side and a Korean one on the other. The Western side turns chalky white; the Korean side disappears. The camera shows the difference directly. No words needed. The proof is the ad. Other formats run on the same logic: a close-up of the formula sinking in like water; a UV camera visualizing actual protection; a real-time demo of reapplying over makeup without smudging it. Consumers aren't asked to "trust us" — they see the result with their own eyes.

And this content isn't found by searching. It's stumbled upon while scrolling the For You feed. The content itself is the point of sale — not a shelf, not a banner.

Lesson two: don't claim, show. If your product delivers a result you can put in front of someone's eyes, that demonstration is your most powerful ad.

Three — While Everyone Shouts "SPF 50," Each Brand Claims One Word

Now the brands enter — and here's where K-beauty marketing gets clever. They don't compete on the same axis. Each brand picks a single word and makes it its own, so that in the consumer's mind it becomes "for this concern, this brand." (And in Exolyt, you can often see whether that word has crossed from a brand's ads into consumers' own hashtags.)

• SKIN1004 — built around cica (Centella asiatica) grown in Madagascar. The word it owns: "no white cast" — the gentle, invisible sunscreen. It's the best-selling Korean sunscreen in the U.S. and the only brand here that tops both online retail and TikTok.
• Round Lab — swaps plain water for birch sap. The word it owns: "anti-aging." It frames sunscreen as wrinkle care rather than mere protection — and "birch sap" has grown into its own standalone hashtag.
• d'Alba — an "affordable luxury" concept fronted by Italian white truffle. The word it owns: "tone-up" — skin that looks instantly brighter. It's the only brand here openly marketing itself as a foundation replacement.
• NIDA — a TikTok-native newcomer. The word it owns: "brightening / whitening." It claimed a lane no other brand here addresses head-on.
• Abib — a stick-format sunscreen. What it owns is less a word than a situation: "reapply outdoors without wrecking your makeup." It competes on convenience, not ingredients — which is exactly why its hashtag network is nearly empty, disconnected from the category conversation (the sharpest finding in this research).
• Beauty of Joseon — inspired by Korea's Joseon-dynasty court beauty recipes. The word it owns: "tinted sunscreen," a term it dominates on TikTok. The reframe behind that word is special enough for its own section, coming up next.

Lesson three: when everyone sells the same thing, you win not by shouting louder but by owning something different. And whether you truly own it shows up when consumers start using your word themselves.

Four — They Rechose Who Delivers the Message, and in Which Language

Traditional beauty marketing bets big money on a single celebrity. Korean sunscreen brands did the opposite: they partner with hundreds or thousands of "ordinary people" — creators with tens of thousands to a few hundred thousand followers — who actually use the product at their own vanity and speak plainly, praising what's good and flagging what's not.

Why does this work better? Because the source of trust is different. A celebrity endorsement reads as an "ad"; a recommendation from someone who looks like you reads as "a friend's advice." In practice, small creators who tell a genuine personal story convert far better than mega-influencers with vastly larger followings.

And here comes the most surprising twist. The "ordinary people" they chose weren't mainstream white Americans. The single biggest growth engine the data points to is, unexpectedly, U.S. Hispanic (Latino) consumers.

The pattern repeats brand to brand. NIDA, the whitening brand from earlier, produces more than 95% of its content in Spanish; "this Korean cream whitened my skin" is its top-performing line, and it has essentially become the go-to sunscreen for U.S. Latina women. d'Alba targets several immigrant communities at once — Spanish, Persian, Punjabi, Vietnamese, English. Even the ingredient-education brand SKIN1004 has a Spanish-speaking creator as its single top revenue driver. Given that K-beauty awareness in Brazil and Mexico already rivals or exceeds the U.S. — riding the wave of K-pop and K-dramas — Spanish-speaking consumers inside the U.S. are the domestic extension of that same current.

Lesson four: use data to find out who actually buys your product, then speak through people they trust, in the language they speak. Most brands imagine the audience they wish they had; these brands followed the audience they really have.

Five — What You Can't See from the Outside: What Consumers Actually Say

There's a layer you can never see from sales figures or ads alone: the comments. Run sentiment analysis in Exolyt to see what people repeat about these sunscreens, and a truer picture emerges than any marketing shows.

The praise is remarkably one-directional. Nearly every brand is loved for being "lightweight," "no white cast," "doesn't even feel like sunscreen." Consumers themselves confirm that this category solved the problem Western SPF couldn't for a decade.

But the complaints are just as legible. Three recur: stinging eyes, suspicion that the U.S. version differs from the original Korean one (same name, reformulated because of U.S. regulations), and scattered reports of irritation or breakouts. None of this shows up in a sales ranking — yet it's exactly what makes people hesitate to buy.

Lesson five: social listening tells you why people don't buy. Sales reveal why a product sells; the reasons people don't buy — and what to fix next — live only in what people actually say.

Six — The Cleverest Move: Don't Add a Benefit, Remove a Barrier

Now for the brand I saved: Beauty of Joseon, which pulls off the single smartest move in K-beauty marketing.

Most brands try to win by adding something — lighter, more hydrating, more anti-aging. Beauty of Joseon went the other way: instead of adding a benefit, it removed a barrier to purchase. Its hero product is a lightly "tinted" sunscreen — one with just enough coverage to even out skin tone. The catch: tinted products read as women's makeup, which makes men reluctant to buy them. So the brand's message boiled down to one sentence: "This isn't makeup. It's sunscreen."

That single reframe opened a market no other sunscreen had cracked — men. In fact, this brand's top creators skew notably male, recommending it to other guys with exactly that line: "I'm not doing makeup, I'm putting on sunscreen." For a man, wearing "makeup" is a psychological barrier; wearing "sunscreen" isn't. What they sold wasn't coverage — it was permission to wear it.

Even as the brand insists "it's not makeup," its hashtag map still carries prominent tags for "SPF makeup" and a major beauty retailer. Consumers — and the algorithm — haven't fully detached the product from the makeup category. The barrier-removal strategy is working, but it's still in progress.

Lesson six: sometimes the way to grow a market isn't a better product — it's removing the psychological obstacle that was stopping people from buying.

In the End, What They Sold Wasn't Sunscreen

Back to the opening question. How do you sell the most boring product on earth?

Here's the answer: they didn't sell sunscreen. SPF 50 is a baseline every brand shares equally — and no one wins on it alone. Instead, they sold the thing people actually wanted underneath it: reassurance for sensitive skin, anxiety about aging, a brighter-looking face, mess-free convenience, lighter-looking skin, and permission for men to wear it. Sunscreen was just the vessel for the desire.

The lesson reaches far beyond beauty. For almost any product, the specs are broadly similar, and specs alone rarely win. The winning brand isn't the one with the best performance — it's the one that most clearly owns the job the consumer is really trying to get done. And whether that ownership is real is only proven when consumers start using your words for you.

Don't sell the spec — sell the desire underneath it. And if you want to know where that desire is flowing right now, don't listen to your sales. Listen to the conversation. Sunscreen was never really sunscreen.
