Korean skin care: the routine, the steps that matter, and what to skip
Korean skin care explained: the routine, which of the famous steps actually matter, popular ingredients, and what to know about Korean sunscreens in the US.
The short answer
Korean skin care is about gentle cleansing, light hydration and daily sunscreen; you do not need ten steps. The steps that matter: double cleanse at night, moisturize, and wear sunscreen every morning. Korean sunscreens often use UV filters US sunscreens could not; the FDA began adding one, bemotrizinol, in 2025 and 2026.
- Add one new product at a time and patch test; do not over-exfoliate.
Korean skin care is known for long, layered routines, but the idea behind it is simple: cleanse gently, keep skin hydrated in light layers, and protect it from the sun every day. You do not need ten steps. A good Korean skincare routine can be five, and most of the benefit comes from three of them: a gentle cleanse, a moisturizer and daily sunscreen. Here is the routine, which steps are worth it, and what to know about Korean sunscreens if you live in the US.
The Korean skincare routine, step by step
| Step | What it does | Worth it? |
|---|---|---|
| Oil cleanser (evening) | Dissolves sunscreen and makeup | Yes, if you wear sunscreen or makeup |
| Water-based cleanser | Removes sweat and the rest of the residue | Yes |
| Toner | Rehydrates after cleansing; Korean toners are usually gentle, not astringent | Optional |
| Essence or serum | A light layer of a targeted ingredient | Optional; choose one for your main concern |
| Moisturizer | Seals in hydration | Yes |
| Sunscreen (morning) | Protects from UV, the main cause of visible skin aging | Yes, every day |
| Sheet masks, ampoules, eye cream | Extra hydration or treatment | Optional extras |
The core is cleanse, moisturize, protect. Everything else is a choice.
What is double cleansing?
Double cleansing means washing your face twice in the evening: first with an oil or balm cleanser, which dissolves sunscreen, makeup and oil, then with a gentle water-based cleanser. It is the most useful Korean habit to borrow if you wear sunscreen daily, because water-based cleansers alone often leave sunscreen behind. In the morning, one gentle cleanse or a splash of water is enough.
A simple 5-step Korean skincare routine
- Morning: gentle cleanse, light serum or essence if you use one, moisturizer, sunscreen.
- Evening: oil cleanser, water-based cleanser, serum or treatment, moisturizer.
If you use a retinoid, add it in the evening and keep the rest simple; our guide to retinal vs retinol explains how to start. For a targeted serum, see peptides for skin.
Popular Korean skincare ingredients
- Centella asiatica (cica): a plant extract used in soothing products for redness-prone skin.
- Snail mucin: a hydrating ingredient that gives essences their slippery texture.
- Rice: used in toners and cleansers for a soft, brightening feel.
- Ginseng and green tea: antioxidant-rich plant extracts.
- Hyaluronic acid and ceramides: the hydration and barrier ingredients behind the "glass skin" look.
Many of these are pleasant and hydrating; the most proven anti-aging steps are still daily sunscreen and, at night, a retinoid.
Korean sunscreens and the US
Korean sunscreens are popular because they feel light and leave no white cast. One reason is that Korea, like Europe, allows UV filters that US sunscreens could not use. In the US, sunscreens are regulated as over-the-counter drugs, so each active ingredient needs a drug review, and Healio reports that no new ingredient had been added since 1999; the US has far fewer filters than the roughly 30 used elsewhere. That started to change when the FDA proposed adding bemotrizinol, a broad-spectrum filter also known as Tinosorb S, in December 2025, and it was reported cleared in June 2026.
If you buy imported Korean sunscreen, check that it says broad spectrum and has an SPF of at least 30, apply it generously, and reapply every two hours outdoors. Imported products may not have gone through US testing.
Glass skin: what it means
"Glass skin" is the Korean beauty ideal of skin so hydrated and even that it looks luminous. It comes from consistent hydration, sun protection and a healthy barrier, not from one product. Skin texture and pores are normal; filters online make glass skin look more achievable than it is.
Common mistakes
- Too many actives at once: layering exfoliating acids, vitamin C and retinoids can irritate. Introduce one new product at a time.
- Skipping sunscreen while buying every other step.
- Over-exfoliating in pursuit of glass skin; a tight, shiny, stinging face is irritated, not glowing.
- Not patch testing new products on a small area first.
