The Complete Guide to Double Cleansing: Korean Beauty's #1 Rule
If there is one step that defines Korean skincare, it is double cleansing. Every K-Beauty expert, dermatologist, and beauty influencer in Seoul will tell you the same thing: your entire routine is only as good as your cleanse. No serum, ampoule, or cream can work properly if it is sitting on top of leftover sunscreen, makeup residue, or oxidized sebum. Double cleansing is the foundation that makes everything else possible.
Double cleansing was popularized in Korea decades before it became a global trend. Korean women noticed that a single wash never fully removed the heavy UV protection and makeup they wore daily. The solution was elegant and simple: use two different types of cleansers, each targeting different types of impurities. Today, double cleansing is practiced by millions of people around the world, and it remains the most universally recommended first step in any K-Beauty routine.
What Is Double Cleansing?
Double cleansing is exactly what it sounds like: washing your face in two steps using two different cleansers. The first step uses an oil-based cleanser to dissolve oil-soluble impurities such as sunscreen, makeup, sebum, and pollution. The second step uses a water-based cleanser to remove water-soluble impurities like sweat, dirt, and any residue left behind by the oil cleanser.
Think of it this way. Oil and water do not mix. A water-based face wash alone cannot effectively dissolve oily sunscreen or silicone-based primer. You need an oil-based product to break those down first. After the oil cleanser lifts the oil-based impurities, the water-based cleanser sweeps away everything else, leaving your skin truly clean without being stripped or tight.
This two-phase approach ensures that your skin is a perfectly clean canvas. Active ingredients in your toner, serum, and moisturizer can then penetrate properly instead of sitting on top of a film of residue. Many people who adopt double cleansing report fewer breakouts, reduced blackheads, and a noticeable improvement in how well their other products perform.
Oil Cleanser vs Water Cleanser: What Is the Difference?
Oil Cleansers (First Cleanse)
Oil cleansers come in several forms: cleansing oils, cleansing balms, and micellar waters. The principle behind all of them is the same. The oil-based formula binds to oil-soluble substances on your skin and lifts them away. When you add water and massage, most oil cleansers emulsify, meaning they turn milky and rinse off cleanly without leaving a greasy film.
- Cleansing oils are liquid formulas that you pump onto dry hands and massage into dry skin. They emulsify quickly and work well for daily use.
- Cleansing balms are solid at room temperature but melt into an oil when you warm them between your palms. They are travel-friendly and feel luxurious on the skin.
- Micellar water uses tiny oil molecules suspended in water to attract impurities. It is the gentlest option but may not fully remove heavy waterproof sunscreen.
Water Cleansers (Second Cleanse)
Water-based cleansers are the familiar foams, gels, and cream cleansers. They work with water to remove sweat, dirt, and the last traces of your oil cleanser. The key for K-Beauty is choosing a low-pH cleanser in the range of 5.0 to 6.0. Your skin's natural pH is slightly acidic (around 5.5), and a low-pH cleanser respects this balance. High-pH cleansers, such as traditional bar soaps, can disrupt the acid mantle and cause dryness, irritation, and breakouts.
How to Double Cleanse: Step-by-Step Guide
Step 1: Apply Oil Cleanser to Dry Skin
Start with completely dry hands and a dry face. Pump or scoop your oil cleanser and apply it directly to your skin. This is essential because oil cleansers emulsify on contact with water, so applying to wet skin reduces their effectiveness. If you are using a balm, warm it between your palms first until it melts into an oil.
Step 2: Massage for 60 Seconds
Gently massage the oil cleanser all over your face using circular motions. Pay extra attention to areas where sunscreen and makeup accumulate: around the nose, along the jawline, across the forehead, and around the eyes. You should be able to feel the makeup and sunscreen dissolving under your fingertips. Spend a full 60 seconds massaging. This is also when the oil cleanser can help dissolve sebum plugs in your pores, so take your time.
Step 3: Emulsify with Water
Wet your hands with lukewarm water and continue massaging your face. The oil will turn milky white as it emulsifies. This is the chemical reaction that allows the oily residue to be rinsed away with water. Massage for another 15 to 20 seconds as the cleanser emulsifies.
Step 4: Rinse Thoroughly
Rinse your face completely with lukewarm water. Avoid hot water, which can strip your skin and cause redness. Make sure to rinse along the hairline, jawline, and around the nose where residue tends to linger. Your skin should feel smooth but not squeaky clean at this point.
Step 5: Apply Water-Based Cleanser
With your face still damp, apply your water-based cleanser. If it is a foaming cleanser, lather it in your hands first to create a rich foam, then apply to your face. If it is a gel cleanser, apply a small amount directly and work it across your skin. Massage gently for 30 to 45 seconds.
Step 6: Rinse and Pat Dry
Rinse thoroughly with lukewarm water and gently pat your face dry with a clean towel. Do not rub. Your skin should feel clean, hydrated, and comfortable, never tight or stripped. Immediately follow with your hydrating toner within 3 seconds while your skin is still slightly damp for maximum absorption.

The low-pH, slightly foaming gel formula is ideal for dehydrated skin that feels tight after washing. It removes impurities gently while depositing a layer of hydration that preps skin perfectly for the rest of your routine. The fragrance-free, minimal formula is safe for sensitive and reactive skin.
Common Double Cleansing Mistakes to Avoid
- Applying oil cleanser to wet skin: This is the most common mistake. Oil cleansers need to contact your dry skin to dissolve oil-based impurities. Water causes them to emulsify prematurely, reducing effectiveness.
- Rushing the massage: Spending only 10 or 15 seconds on your oil cleanse is not enough. You need a full 60 seconds of gentle massage for the oil to properly dissolve sunscreen and sebum. Set a timer until you build the habit.
- Using hot water: Hot water feels satisfying but strips your natural oils and weakens the skin barrier. Always use lukewarm water for both rinse steps.
- Over-cleansing in the morning: Double cleansing is primarily for your PM routine to remove the day's sunscreen, makeup, and accumulated sebum. In the morning, a single water-based cleanser is usually sufficient since your skin has only been in contact with your pillow and your own natural oils overnight.
- Choosing a high-pH second cleanser: A cleanser with a pH above 7.0 can damage your acid mantle, leading to dryness, sensitivity, and even acne. Always check the pH of your water-based cleanser. Aim for 5.0 to 6.0.
- Skipping double cleansing on no-makeup days: Even if you did not wear makeup, you still wore sunscreen (you did wear sunscreen, right?). Sunscreen, especially physical and water-resistant formulas, requires an oil cleanser to remove completely. Leftover sunscreen can clog pores and cause breakouts.
When to Double Cleanse (and When Not To)
Always double cleanse in the evening after wearing sunscreen, makeup, or spending time outdoors. This is when your skin has accumulated the most oil-soluble impurities that a single cleanser cannot handle.
Skip the oil cleanser in the morning. Overnight, your skin produces only a light layer of sebum and no sunscreen or makeup residue. A gentle water-based cleanser, or even just a splash of lukewarm water, is enough for your morning routine. Over-cleansing in the morning can strip your skin and trigger excess oil production throughout the day.
Exception: If you used a heavy occlusive sleeping mask or rich overnight treatment, a quick oil cleanse in the morning can help remove the residue so your daytime products absorb properly.
Frequently Asked Questions
Can I double cleanse if I have acne-prone skin?
Absolutely. In fact, double cleansing is especially beneficial for acne-prone skin. Leftover sunscreen and sebum are major contributors to clogged pores and breakouts. The key is choosing non-comedogenic oil cleansers formulated for acne-prone skin, such as the Anua Heartleaf Cleansing Oil, which contains soothing and antibacterial ingredients. Avoid heavy mineral oil-based cleansers and opt for plant-derived oils that rinse clean.
Is double cleansing necessary if I do not wear makeup?
Yes. Double cleansing is not just about removing makeup. Its primary purpose is removing sunscreen, environmental pollution, and excess sebum. Sunscreen, especially mineral and water-resistant formulas, forms a protective film that a water-based cleanser alone cannot fully break down. If you wear sunscreen daily (which you should), double cleansing is essential regardless of whether you wear makeup.
Will oil cleansing make my oily skin worse?
No. This is a common myth. Oil dissolves oil, so an oil cleanser actually removes excess sebum more effectively than a foaming wash alone. Quality oil cleansers are formulated to emulsify and rinse away completely, leaving no oily residue behind. Many people with oily skin find that their sebum production actually decreases after adopting double cleansing because their skin barrier is no longer being stripped and overcompensating.
Can I use coconut oil as my first cleanser?
It is not recommended. While coconut oil can dissolve makeup, it has a high comedogenic rating and does not emulsify with water, meaning it will not rinse off cleanly. You will be left with a greasy film that can clog pores and cause breakouts. Invest in a proper cleansing oil or balm formulated for the face. They contain emulsifiers that allow the oil to mix with water and rinse away completely, which is the entire point of the first cleanse.
