The 10-Step Routine: More Products, More Profit, Not Better Skin

Double cleanse. Toner. Essence. Serum. Ampoule. Sheet mask. Eye cream. Moisturiser. Facial oil. Sunscreen. The elaborate multi-step routine has become aspirational skincare — a ritual promising transformation through layering. But more steps mostly means more purchases, not better results.

Where The Multi-Step Routine Came From

The 10-step routine was popularised through K-beauty — the wave of Korean skincare that reached Western markets in the mid-2010s. It was presented as the secret behind Korean women’s famously good skin, a dedicated practice of layering products in specific order for maximum benefit.

The cultural framing was appealing: skincare as self-care ritual, an investment of time that shows investment in yourself. The routine became aspirational, something to work toward rather than question.

What wasn’t emphasised: this also meant buying 10 products instead of four. The average consumer who adopted the full routine was spending significantly more — and replenishing 10 products at different intervals kept them continuously purchasing.

The Diminishing Returns Problem

Here’s what dermatology actually supports: a good skincare routine needs cleanser, moisturiser, and sunscreen. That’s the foundation. Everything else is optional — potentially beneficial, but not necessary.

Adding targeted treatments — a retinoid for anti-aging, a vitamin C serum for antioxidant protection, an exfoliant for texture — can enhance results. That brings you to perhaps five or six products, applied strategically.

Beyond that, diminishing returns set in sharply. Your skin can only absorb so much. It can only respond to so many active ingredients simultaneously. Layering 10 products doesn’t deliver 10 products’ worth of benefit — it delivers the benefit of what actually penetrates and works, plus the burden of everything else sitting on your skin.

The Redundancy Reality

Many multi-step routines involve redundant products — items that sound different but do essentially the same thing:

Toner, essence, and serum. These are all water-based products delivering actives to the skin. The distinctions are mostly textural and marketing-driven. An essence is typically lighter than a serum. A toner can be hydrating (like an essence) or exfoliating (like a treatment). You don’t need all three; you need whichever delivers the ingredients you want.

Ampoule and serum. An ampoule is typically a concentrated, short-term treatment. A serum is a daily treatment product. Using both simultaneously often means layering similar actives at combined concentrations that might exceed what’s optimal — or simply wasting product as the skin can’t absorb both.

Eye cream and moisturiser. Eye cream is often just moisturiser in a smaller, more expensive package. Unless it contains specific ingredients (retinol, peptides, caffeine) at concentrations your regular moisturiser doesn’t, you’re paying premium prices for location-specific marketing.

Moisturiser and facial oil. These serve overlapping purposes. Some skin types benefit from both; many don’t need both. Using both when your skin is already adequately moisturised just creates a heavier feel without additional benefit.

The Business Model Behind Complexity

Multi-step routines are extraordinarily profitable for the skincare industry:

More products per customer. Instead of selling you one cleanser and one moisturiser, brands sell you 10 products. Revenue per customer multiplies.

Continuous replenishment. Products run out at different rates. You’re always buying something. There’s no natural pause in the purchasing cycle — the same rhythm subscription auto-ship models are built to lock in permanently.

Routine lock-in. Once you’ve built a 10-product routine, switching brands means replacing multiple products. The friction of changing keeps you buying from familiar brands.

Premium positioning for each step. Each category becomes a purchase decision. Essence becomes a product category worth £30–60. Ampoule becomes a category worth £40–80. Categories that didn’t exist become revenue streams.

Aspirational marketing. The elaborate routine becomes a status symbol. Having the “full” routine signals dedication and investment. Minimalism becomes unfashionable.

The Skin Health Perspective

More products isn’t just unnecessary — it can be counterproductive:

Increased irritation risk. Every product you apply introduces potential irritants — preservatives, fragrances, actives your skin might not tolerate. More products mean more opportunities for sensitisation.

Ingredient conflicts. Layering multiple actives can create conflicts. Vitamin C and niacinamide were long thought to be incompatible (this has been largely debunked, but the principle holds for other combinations). AHAs and retinol together can over-exfoliate. More products increase the chance of problematic combinations.

Barrier compromise. Over-application, particularly of exfoliating or active products, can damage the skin barrier. Multi-step routines make it easier to accidentally overdo it.

Harder to identify problems. If you’re using 10 products and your skin reacts badly, which one caused it? With simpler routines, problem identification is straightforward. With complex routines, you’re guessing.

What Actually Works

The evidence supports simpler routines with well-chosen products:

Cleanser. One gentle cleanser that removes makeup and daily grime without stripping. Double cleansing — oil-based then water-based — can be useful for heavy makeup wearers, but one good cleanser is sufficient for most.

Active treatment. One or two products with evidence-backed actives at therapeutic concentrations. A retinoid, a vitamin C serum, an exfoliant — choose based on your skin concerns, not based on filling routine slots.

Moisturiser. One product that maintains hydration and supports barrier function. Adjust richness for your skin type and climate.

Sunscreen. Non-negotiable. Daily. SPF 30 minimum, broad spectrum.

That’s four products, five or six with targeted treatments. It’s not exciting. It doesn’t fill a shelfie photo. It works.

The Cultural Shift

Interestingly, even the K-beauty market has started moving away from 10-step routines. The “skip-care” movement — focusing on fewer, more effective products — emerged as a countertrend. Korean consumers themselves were finding the elaborate routine unsustainable.

Western markets are following, though the industry resists. “Skinimalism” became a trend precisely because the maximalist approach had overreached. Consumers burned out on elaborate routines that delivered complexity without proportional results.

The brands that sold you the 10-step routine are now selling you the minimalist edit. Same margins, different marketing.

The Bottom Line

The 10-step routine was always more about marketing than skin science. It created categories, filled shelves, and multiplied purchases. It made skincare feel like a hobby requiring extensive gear rather than a simple health practice.

Your skin doesn’t know how many products you own. It responds to the ingredients it receives at the concentrations that work. A four-product routine with well-chosen formulas will outperform a 10-product routine of redundant layers.

If you enjoy the ritual of an elaborate routine — the time spent, the layering, the self-care aspect — that’s valid. But don’t mistake complexity for efficacy. More products means more spending, more potential for irritation, and more difficulty identifying what actually works. It rarely means better skin.
