I coordinate influencer gifting for a Korean fashion label. I have seen the spreadsheets. I know how much a "viral moment" costs, how a seeding list of 200 micro-influencers gets compressed into "everyone is talking about this," and how a brand will reformulate a product to be cheaper and relaunch it as "new and improved."
When I see a skincare product go viral on TikTok, my first question is not "does it work?" It is "who paid for this?"
The economics of a viral product
A mid-tier K-beauty brand launching in the U.S. market budgets between $30,000 and $80,000 for a single product push on TikTok. That covers: gifting to 150-300 creators, paid partnerships with 5-10 higher-reach accounts, and a seeding campaign that creates the illusion of organic discovery. By the time you see three different people in your feed talking about the same serum in the same week, that is not coincidence. That is a media buy.
This is not a conspiracy. It is standard practice. I see it at work every day.
"Cult favorite" means someone spent money
The phrase "cult favorite" has no definition. It is not earned through years of loyal customers. In practice, it means a product hit a certain sales velocity on Amazon or Sephora after a coordinated push. The velocity creates the bestseller ranking, the ranking creates the press coverage, the press coverage creates more sales. It is a flywheel, and someone paid to spin it.
What I actually trust
I trust products that have been around for years without needing a rebrand. COSRX Snail 96 has looked the same since I first bought it in 2019. The formula has not changed to chase a trend. That kind of boring consistency is what I look for.
I trust products where the ingredient list matches the marketing claims. If a brand says "niacinamide serum" and niacinamide is the seventh ingredient after water, glycerin, and four thickeners — that tells me the marketing budget was bigger than the R&D budget.
I trust my own face. I test everything for at least two weeks before I write about it. Sometimes three. I take photos. I note the weather, my stress levels, whether my period is coming. Skincare results are noisy. A seven-second TikTok clip cannot capture that.
The real problem with viral skincare
The damage is not that a hyped product might be mediocre. The damage is that viral cycles train people to buy constantly and evaluate nothing. A new product every month. A new routine every season. A five-step Korean routine repackaged as a twelve-step routine because more steps means more products means more revenue.
Skincare is not fashion. Your skin does not need a new wardrobe every quarter. The best routine is the boring one you actually do every night — even when you are exhausted.
What I want Seoul Rite to be
I want this to be the one place where someone tells you the truth: most products are fine, a few are worth keeping, and the best thing you can do for your skin costs nothing. Wash your face. Wear sunscreen. Sleep. The rest is personal.
