What is the double cleansing method?

Double cleansing is a two-step cleansing approach central to Korean skincare. The first step uses an oil-based cleanser (oil cleanser, cleansing balm or micellar oil) to dissolve sunscreen, makeup and excess sebum. The second step uses a water-based cleanser (gel, foam or cream) to remove any remaining residue and cleanse the skin itself. The method is particularly important if you wear SPF or makeup, as water-based cleansers alone often cannot fully remove SPF films. The two-step approach achieves thorough cleansing without requiring an overly harsh single cleanser.

Do I need to double cleanse every morning?

Generally, no — double cleansing in the morning is not necessary for most people. In the morning, skin has only been in contact with your pillowcase and overnight skincare products, which are far less difficult to remove than SPF or makeup. A gentle rinse with water or a single light cleanse is sufficient for most people in the morning. Double cleansing is most useful and appropriate in the evening, particularly if you have worn SPF or any makeup.

What pH should a Korean cleanser be?

A skin-friendly cleanser should have a pH of approximately 4.5–5.5 — close to the natural pH of skin. High-pH cleansers (particularly traditional bar soaps, which are often pH 9-10) can disrupt the skin's acid mantle, leaving it feeling tight and vulnerable. Many Korean cleansers are formulated with low-pH in mind, and some brands publish pH values. If you are unsure, look for reviews that include pH testing, or choose cleansers described as 'pH-balanced' or 'for sensitive skin'.

Are foaming cleansers bad for skin?

Not inherently, but harsh foaming cleansers — particularly those that leave skin feeling very tight or 'squeaky clean' — are often too stripping for many skin types. A good foaming or gel cleanser can be excellent, provided it uses skin-friendly surfactants and is formulated at an appropriate pH. The 'squeaky clean' feeling after cleansing is often a sign that the skin barrier has been over-stripped. A well-formulated foam cleanser should leave skin feeling clean but comfortable, not tight.

Can dry skin use oil cleansers?

Yes — oil cleansers are actually well-suited to dry skin. They dissolve product and sebum without using the stripping surfactants found in some water-based cleansers. When massaged onto dry skin and then emulsified with water, a good oil cleanser leaves the skin clean without the tight, stripped feeling. For dry skin, look for richer oil cleansers with moisturising oils, or a balm-type cleanser.

Korean cleanser products for double cleansing — oil cleanser and foam cleanser

Cleansing is the foundation of any skincare routine — and Korean skincare has a particularly thoughtful approach to it. Rather than a single, all-purpose cleanser, Korean beauty often uses two steps: an oil-based first cleanse and a water-based second cleanse. The goal is thorough cleansing without stripping.

This guide covers the different types of Korean cleansers, when and why to use each, the importance of pH, and how to choose the right cleanser for your skin type.

The double cleansing method

Step 1 — Oil-based cleanser

Applied to dry skin, massaged gently to dissolve SPF, makeup, excess sebum and oil-based impurities. Then add water to emulsify (turns milky white) and rinse off.

Types: cleansing oils, cleansing balms, micellar oils

Step 2 — Water-based cleanser

Applied to damp skin after the oil cleanse, to remove any remaining residue and cleanse the skin surface itself. Rinse thoroughly.

Types: gel cleansers, cream cleansers, foam cleansers, low-pH cleansers

Types of Korean cleansers

Cleansing oil

All skin types, SPF wearers

A liquid oil that dissolves sebum, sunscreen and makeup effectively. Applied to dry skin, massaged, then emulsified with water. Leaves skin feeling clean without stripping.

Cleansing balm

Dry, mature, sensitive skin

A solid or semi-solid oil-based cleanser that melts on contact with skin. Often richer than liquid oil cleansers — can feel very comfortable for dry skin types.

Micellar oil

Sensitive skin, light makeup

A hybrid formula that combines oil and water-loving molecules. Can be used with or without rinsing depending on formulation.

Low-pH gel cleanser

Oily, combination skin

A water-based cleanser formulated at skin-friendly pH (4.5–5.5). Cleanses effectively without over-stripping. Often the most recommended format in K-beauty routines.

Cream/milky cleanser

Dry, sensitive, mature skin

A gentle, non-foaming formula that cleanses while leaving a moisturised feeling. Often the best choice for dry or sensitive skin as a second cleanse step.

Foaming cleanser

Oily skin (if skin-friendly formula)

Creates a lather and is often felt as deeply cleansing. Can be stripping if poorly formulated — choose low-pH, skin-appropriate versions for oily skin.

Why pH matters in cleansers

Skin has a naturally acidic surface environment — the acid mantle — at approximately pH 4.5–5.5. High-pH cleansers (particularly traditional soap bars at pH 9-10) disturb this environment, which can disrupt the skin barrier, alter the microbiome and increase sensitivity and dryness.

Many Korean cleansers are specifically formulated at low pH to respect the skin's natural environment. If a cleanser leaves your skin feeling tight, dry or uncomfortable after rinsing, it may be too alkaline (high-pH) for your skin.

How often to cleanse

Morning

A gentle water rinse or single light cleanse is sufficient for most people. SPF and makeup from the previous day should have been removed the night before.

Evening (SPF / makeup worn)

Double cleanse: oil-based first cleanse, then water-based second cleanse.

Evening (no SPF / makeup)

A single gentle water-based cleanse is usually sufficient.

Common cleansing mistakes

Over-cleansing — more than twice a day is rarely necessary and can strip the skin barrier.

Using water that is too hot — use lukewarm water to avoid stripping natural oils.

Not rinsing thoroughly — product residue left on skin can cause congestion.

Choosing a cleanser that is too harsh for your skin type based on marketing alone.

Rubbing skin aggressively to dry — always pat gently with a clean towel.
