Cleansing is a market with nearly 100% penetration. Everyone washes their face, so most assumed innovation was over. Then, over the past year, two categories grew triple digits at the same time in US search data. (Figures below per Spate, US search data.)
01Two categories grew triple digits — at once
Per Spate, the two categories that moved sharply over the past year are the sebum softener and the whipped cleanser.
Two cracks in a saturated market
Both markets are still small. But small means it can still be claimed first.
02Not a wash product — a pre-wash product
A sebum softener isn't a cleanser. It's a new step created before the cleanser. The sequence looks like this — soften hardened sebum → loosen blackheads → cleanse.
Per Spate, monthly searches sit at 4,100 — still small — but the keyword takes 65.7% of search share and draws 1.6M weekly views on TikTok. Here's the core of it: people don't search for "a good cleanser." They search their concerns — blackheads, sebum, pores.
A Korean routine the world just named
Look at what gets searched alongside it
- Co-searched terms — concern keywords like blackheads, sebum, and pores appear together with "Korean Skincare" (Spate)
- The top two brands are both Korean — this category's country of origin is Korea
- Overseas markets are now naming it "Sebum Softener" — Korea has been using the routine for years
03It's not the ingredients — it's the texture
The whipped cleanser's differentiator isn't on the ingredient list. It's the air-whipped foam itself. What consumers respond to: the pillowy foam, the soft touch, and a finish that doesn't feel tight after rinsing.
The discovery path is the interesting part. Monthly searches are only 800 — but TikTok takes 69.8% of share (Spate). In other words, this is a product that gets seen, not searched. Creator collaborations and TikTok Shop are pulling the growth.
04One gets searched. One gets shown.
Same cleansing aisle — completely different entry grammar.
Search claim vs. exposure design
- Concern → search → discovery — demand already exists
- 65.7% search share (Spate)
- Entry mode: claim it first — whoever owns the keyword wins
- Video → exposure → purchase — demand must be created
- 84.5% ad exposure · 57.2% TikTok Shop inflow (Spate)
- Entry mode: creator collabs + TikTok Shop integration
Products didn't multiply.
The seats did.
05Cleansing stopped being one step
One cleanser used to be the whole routine. Now it splits — soften sebum → cleanse → soothe. With penetration at 100%, there are no new users to win, so growth comes from only two places: add a step, or change the experience.
The sebum softener added a step; the whipped cleanser changed the experience. The cleanser market is mature — but cleansing has only just begun to split.
A big growth rate also means the market is still small. Absolute search volumes are low, and whipped's high ad-exposure share means it could fade if the ads switch off. And definitive claims like "removes blackheads" or "shrinks pores" require substantiation — LUK Corp. keeps efficacy claims within test results and reviews wording against each market's labeling and advertising rules.
06New category before new product — four OEM insights
Rename what you already have
Redefine oil cleansers and cleansing balms in the "sebum softening" grammar. Zero development cost to board a new category.
Keywords before brand names
Blackheads, pores, sebum — plant the concern keywords in the product page first. People search concerns, not brands.
Whipped needs TikTok Shop
A product that gets seen has the same discovery and sales channel. Build creator collabs and TikTok Shop integration in from day one.
Tie Korean ingredients to the texture story
Mung bean, rice, ginseng — Korean ingredients with verified search demand, woven into the texture narrative. Ingredients earn the click; texture earns the memory.
How this fits the framework
This is the "step-splitting" dimension of the LUK Insight series — just as base makeup moved to "barrier" and sun care to "the reason," face washing is shifting its center of gravity from "cleansing power" to "routine design." The cleansing-power race is over; the routine is splitting into before-the-wash and during-the-wash. The next winner isn't the brand that washes best — it's the brand that owns a step. Who will name the "pre-wash" step first?
07OEM FAQ
Can LUK Corp. develop a "sebum softener"?
Yes. We can develop pre-wash step products (oil, gel, or essence types) that soften hardened sebum. That ranges from repositioning an existing oil cleanser or cleansing balm in the sebum-softening grammar, to a dedicated new formulation.
Can the whipped "foam texture" be engineered in the formula?
Yes. We design the air-whipped texture (mousse / whipped type) together with a mild surfactant system that doesn't leave skin tight. Since the "seen" texture is the point, we also optimize foam density and shape retention with the demo video in mind.
Can we claim "removes blackheads" or "shrinks pores"?
Definitive wording requires substantiation. LUK Corp. adjusts copy to what testing can support (e.g., cleanses impurities, helps care for sebum) and, where needed, designs human-application studies to build the evidence. Market-specific reviews (Korea MFDS, US MoCRA, EU) are included.
Can Korean ingredients like mung bean, rice, or ginseng be used?
Yes. We formulate around Korean ingredients with verified search demand (mung bean, rice, ginseng, and more) and weave them into product names and detail-page keywords — the "search design" comes built in.
What are the MOQ, lead time, and payment terms?
MOQ is 5,000 units per SKU (pilots around 2,000 negotiable), lead time roughly 2–3 months for a first order (plus testing time), and payment 50% deposit / 50% balance before shipping. We provide a combined schedule in the proposal.
