The Korean Skincare Routine: All 10 Steps, and Which Ones You Can Skip

A Korean skincare routine traditionally runs in 10 steps: oil cleanser, water-based cleanser, exfoliator, toner, essence, serum or ampoule, sheet mask, eye cream, moisturizer and, in the morning, sunscreen. Most of the visible benefit comes from four of them: a gentle cleanse, a hydrating layer, a moisturizer and daily SPF. The other six are optional tools for specific goals.

Below we go through all 10 steps in order, explain what essences, ampoules and sheet masks add (and what the studies behind them actually show), then cut the routine down to a five-step version a beginner can keep up with.

What are the 10 steps of a Korean skincare routine?

The 10 steps move from cleansing to treating to sealing, with the thinnest, most watery products first and the thickest last. Here they are with an honest note on which ones most people can skip.

The order follows the same rule as any routine: thin to thick, water-based before oil-based, sunscreen last in the morning. Our guide to skincare routine order covers where treatments like retinol fit if you use them.

Why does the Korean routine have so many steps?

It has many steps because the format is built around layering hydration in several thin coats and treating prevention, especially sun protection, as daily care. Each watery layer adds humectants, and a moisturizer on top slows the water from leaving again.

Sunscreen sits at the center of the approach. In South Korea, sunscreen falls under "functional cosmetics," a category that the Ministry of Food and Drug Safety says needs an evaluation before sale, with SPF, waterproof SPF and UVA protection (PA) data among the evidence required. That's why a PA grade usually sits beside the SPF on Korean sunscreen labels.

The step count itself is a framework more than a rule. Plenty of people in Korea and elsewhere use four or five products, and the extra steps only help if they solve a problem you actually have.

Do you need to double cleanse?

You need to double cleanse only if you wear makeup, water-resistant sunscreen or long-wear products. Cleveland Clinic dermatologist Jane Wu says that for most people, washing once thoroughly with a gentle cleanser is more than adequate, and that oil-based cleansers can cause breakouts in acne-prone skin when used alone.

The oil step earns its place with water-resistant sunscreen. In a small study of 20 volunteers, a regular cleanser and a cleansing oil removed ordinary sunscreen equally well, but the cleansing oil did best on a waterproof formula, and fewer people reported dryness after the oil (one versus eight). Our guide on how to double cleanse walks through the technique.

Essence vs serum vs ampoule: what's the difference?

An essence is the thinnest of the three, a watery layer used right after toner; a serum is a slightly thicker treatment aimed at one concern; and an ampoule is usually a more concentrated serum sold in a smaller bottle. Brands use these words loosely, so the ingredient list tells you more than the name.

What does an essence actually add? The most-studied example is Galactomyces ferment filtrate, the yeast ferment in many first essences. Two studies of 47 and 57 young Japanese women found that four weeks of a ferment-filtrate formula reduced pore area, roughness and redness compared with their own baseline, and a 12-month study in 86 women reported higher hydration and lower water loss. Both were run by teams that included employees of the company that makes the tested products, and neither used a placebo group, so treat them as encouraging, not settled.

If you only use one of these, pick a serum with an ingredient that has good trial data for your goal. In a 12-week split-face trial, 5% niacinamide reduced spots, red blotchiness and sallowness compared with the plain base. Our guide to layering serums explains how to combine two without overloading your skin.

Do sheet masks actually do anything?

Sheet masks give a real but short-lived boost in hydration, and leaving them on longer makes things worse. In a randomized trial, volunteers wore water, hyaluronan or ferment masks for 5 to 40 minutes. Use under 25 minutes improved hydration and reduced redness, while longer use increased dryness and redness, especially with plain water masks.

So follow the time on the packet, usually 15 to 20 minutes, then pat in what's left and apply moisturizer straight away to seal it. A sheet mask works well before an event or after a dry flight. It doesn't need to be a daily step.

Which K-beauty ingredients have the best evidence?

Hyaluronic acid, niacinamide and centella have the strongest support among the ingredients K-beauty is known for; snail mucin has the least. A quick guide:

• Hyaluronic acid: a humectant that Cleveland Clinic says can hold a lot of water, with reactions to topical products being rare. Seal it with moisturizer in dry air.
• Centella asiatica (cica): in a four-week study of 25 volunteers who applied them to the forearm, creams and gels with 5% centella extract raised hydration by about 22% to 25% and cut water loss by 15% to 18%. See our centella guide for more.
• Snail mucin: a 2024 review found that most studies were preclinical or small clinical studies and called for larger trials and allergy research.
• Niacinamide: backed by the split-face trial above for tone and blotchiness.

What is a simple 5-step Korean skincare routine for beginners?

A five-step Korean skincare routine for beginners keeps the hydration layering and the sunscreen and drops everything else. It looks like this:

Morning

1. Gentle water-based cleanser, or just a rinse if your skin is dry.
2. Hydrating toner or essence, patted in with your hands.
3. One serum for your main concern, such as niacinamide for uneven tone.
4. Moisturizer in a texture that suits your skin type.
5. Broad-spectrum sunscreen, SPF 30 or higher. The American Academy of Dermatology (AAD) says to use at least 1 teaspoon for your face and reapply every two hours when you're outdoors.

Evening

1. Oil cleanser, only on days you wore makeup or water-resistant SPF.
2. Water-based cleanser.
3. Toner or essence.
4. Serum or treatment, such as retinol on alternate nights if you use one.
5. Moisturizer, a little richer than your morning one if you're dry.

Add exfoliation once or twice a week, and a sheet mask when you want one. The AAD notes that over-exfoliating can leave skin red and irritated, and that people with darker skin tones should avoid harsh chemical or mechanical exfoliation because it can cause dark spots. If even five steps sounds like a lot, our simple skincare routine gets it down to three.

How should you start a Korean routine without breaking out?

Start with the five-step version and add one new product at a time, two to four weeks apart, so you can tell what helps and what doesn't. Before using something new on your face, the AAD suggests a home test: apply it to a quarter-sized spot on the inside of your arm twice a day for 7 to 10 days.

If you're acne-prone, be selective. The AAD's acne tips suggest alcohol-free products and skipping astringents, toners and exfoliants that dry the skin, and choosing moisturizers labeled oil-free, non-comedogenic or "won't clog pores". Check the label of any toner before you add it. For painful, deep or scarring acne, see a dermatologist; a longer routine won't replace prescription treatment.

How can a selfie scan help you decide which steps to keep?

The hardest part of a long routine is knowing which steps are doing anything. A consistent photo record makes that easier. Pori takes a selfie and returns an overall skin score from 0 to 100 with a breakdown that includes Hydration & Moisture and Pores & Texture, so you can scan before you add an essence or a sheet-mask habit and compare a few weeks later. Pori's ingredient scanner (a Pro feature) also lets you scan a barcode or photograph a label to see how each ingredient is flagged for your skin type, which helps when you're reading a Korean ingredient list for the first time.

A scan tracks appearance; it isn't a diagnosis. See a dermatologist for a rash, persistent redness or acne that doesn't respond to over-the-counter care.
