Korean Skincare Routine Order: 10 Steps Explained

The Korean skincare routine order is simpler than the "10-step" label suggests: products go on from thinnest to thickest, water-based before oil-based, and sunscreen always last in the morning. Of the ten steps, only four do most of the work: a gentle cleanser, a hydrating layer, a moisturizer, and a broad-spectrum SPF 30 or higher reapplied every two hours outdoors, which is the American Academy of Dermatology's baseline. The rest are optional layers you add for a specific goal.

The Korean skincare routine: ten steps in order

Step	Product	When	Essential?
1	Oil cleanser	Evening (removes SPF, makeup)	If you wear sunscreen daily, yes
2	Water-based cleanser	AM and PM	Yes
3	Exfoliant (AHA/BHA)	1–2 times a week, PM	Optional
4	Toner	AM and PM	Optional, hydrating
5	Essence	AM and PM	Optional
6	Serum or ampoule	AM and PM	For a specific goal
7	Sheet mask	1–3 times a week	Optional
8	Eye cream	AM and PM	Optional
9	Moisturizer	AM and PM	Yes
10	Sunscreen SPF 30+	AM, reapply outdoors	Yes

The logic behind the order is absorption. Watery layers (toner, essence) sink in quickly and would be blocked if you applied them over a cream. Oils and occlusive creams go last because they seal what is underneath. Sunscreen is the one exception to "thin to thick": it sits on top no matter what, and anything applied over it thins the protective film.

What to skip, and what never to skip

Steps 3, 5, 7 and 8 are where most people overspend. An exfoliant is useful for clogged pores or dullness but not more than twice a week, and never on the same night as a retinoid. Essence and toner overlap heavily; one hydrating layer is enough for most skin. Sheet masks are pleasant but deliver roughly what a serum does. Eye cream is a moisturizer in a smaller jar. What you should never skip is cleansing at night and sunscreen in the morning, because those two steps prevent the problems the other eight try to fix.

In my experience living in Seoul, the routine most Koreans actually follow on a weekday is five steps: cleanser, toner, serum, moisturizer, sunscreen. The full ten shows up on weekends or in winter, when indoor heating drops humidity and an extra hydrating layer helps. If you are building the routine from zero, start with the five and add one product at a time for two weeks each, so you can tell which one caused a breakout.

Buying it in Korea

1. Olive Young is the default drugstore chain; most stores have English shelf labels and a tax-refund counter for purchases over 30,000 won.
2. Sunscreen labels use SPF plus a PA rating (PA+ to PA++++). PA++++ is the highest UVA protection and is standard for daily sunscreens here.
3. Check the "제조" (manufacture) or "사용기한" (use-by) date on the box; many serums are good for 6–12 months after opening.
4. Sample sachets are handed out at counters; patch-test a new active with them first.

Summary

1. Order: cleanse, hydrate (toner/essence), treat (serum), moisturize, then sunscreen in the morning
2. Four essentials: gentle cleanser, one hydrating layer, moisturizer, SPF 30+ reapplied every two hours outdoors
3. Exfoliate no more than twice a week; do not stack it with a retinoid
4. Start with five steps and add one product every two weeks

For over-the-counter items you may need alongside skincare, such as antihistamines for a reaction, see the Korean pharmacy guide. If a jjimjilbang visit is on your list, the jjimjilbang etiquette guide covers what to bring for your skin. To check whether a product is within its use-by window, the day counter does the math from the opening date.
