The research behind our Micellar Cleansing Water

How micelles lift makeup without foam or rinsing, why the type of cleansing agent matters so much, what each ingredient adds, and what the research does and doesn't prove.

Cleansing is the step you repeat most, and the one most likely to go wrong. Wash with the wrong product twice a day and you can undo everything the rest of your routine is trying to do. Micellar water is one of the gentlest ways to cleanse, and it is also one of the most misunderstood.

This guide explains what micellar water is, how it works, and why the choice of cleansing agent matters more than anything on the front of the bottle. Then it goes through our Micellar Cleansing Water ingredient by ingredient, with the research behind each one and its limits. If you only want the product, the micellar water page has everything in one place.

01What micellar water actually is

Micellar water is water with a small amount of mild cleansing agent dissolved in it, usually with humectants such as glycerin to keep skin comfortable. It looks and feels like water. You soak a cotton pad, wipe it over your face, and the pad comes away carrying makeup, oil and the day's grime.

The name comes from micelles, the tiny clusters that cleansing agents form in water. There is nothing exotic about them: every shampoo, shower gel and face wash contains micelles too. What sets micellar water apart is how little cleansing agent it uses, which cleansing agents it chooses, and the fact that it is designed to be wiped rather than lathered and rinsed.

Micellar water is often said to have become popular in France, where hard tap water can leave skin feeling tight after washing. Whatever its origins, it is now used everywhere, by people who wear makeup every day, by makeup artists who need to take makeup off without disturbing the skin underneath, and by anyone who wants a quick cleanse without a sink.

02How micelles work

Every cleansing agent has two ends. One end is attracted to water; the other is attracted to oil. In water, the molecules group together into little spheres with their oil-loving ends pointing inwards, away from the water. Those spheres are micelles.

When a micelle meets an oily substance, such as sebum, makeup or the residue of a sunscreen, it can take it into its oily centre. Draw a cotton pad soaked in micellar water across your skin and the micelles pick up that oil and hold it in the water, so it lifts away on the pad.

Because the concentration of cleansing agent is low and there is no foaming or scrubbing, the contact between cleansing agent and skin is short and gentle. That is the whole idea: enough cleansing power to lift makeup, and not so much that it strips the skin.

03Why cleansing can irritate skin

The outer layer of your skin is made of flattened cells held together by lipids, a structure often compared to bricks and mortar. Its job is to keep water in and irritants out. Cleansing agents cannot tell the difference between the oil you want to remove and the lipids your skin needs, and some of them also bind to the proteins in that outer layer.

Research on cleansers has shown that the harsher the cleansing agent, the more it binds to skin proteins and the more lipid it removes. The result is the tight, dry, sometimes itchy feeling many people get after washing. Repeat that twice a day and some skin never fully recovers between washes.

That is why the most important question to ask about any cleanser is which cleansing agents it uses, and how much. The answer matters more than any plant extract on the label.

04How we rate the evidence

None of the studies below tested our micellar water. They tested ingredients, usually in other products or on their own. We use them to explain why each ingredient is in the formula, and we say what each one doesn't prove.

05The cleansing agents: glucosides

The main cleansing agent in our micellar water is caprylyl/capryl glucoside. Glucosides are made by joining a sugar (glucose) to a fatty alcohol from plant oils. They belong to a family called alkyl polyglucosides, and they are non-ionic, which means they carry no electrical charge. Non-ionic cleansing agents tend to bind less to skin proteins than charged ones such as sulfates.

06The second cleanser: polyglyceryl-4 caprate

Alongside the glucoside sits polyglyceryl-4 caprate, a non-ionic ingredient made from glycerin and a fatty acid from coconut or palm oil. It works as a mild cleansing and emulsifying agent, helping the water pick up oily makeup that a glucoside alone might leave behind.

We found no published trial of polyglyceryl-4 caprate on skin that we could summarise, so we give it no evidence label. It is widely used in natural-origin cleansers because it is mild and plant-derived. Its role in this formula is practical: better makeup removal with a low concentration of cleansing agent.

07Betaine

Betaine is a small molecule found in sugar beet. In skincare it works as a humectant, drawing water into the skin's outer layer, and it has been studied for a more specific reason: it appears to reduce the irritation that cleansing agents cause.

08Glycerin and butylene glycol

Glycerin is the most studied humectant in skincare. It draws water into the outer layer of the skin and helps that layer work properly. A detailed review of the research concluded that glycerol improves hydration and barrier function and helps protect skin against irritation. In our micellar water, glycerin is the third ingredient, and it is made using organic ingredients.

Butylene glycol, the second ingredient, is another humectant. It helps the formula hold water and spread evenly on a cotton pad. Under the COSMOS standard, it has to come from a plant source.

09Aloe, the base

The first ingredient is organic aloe leaf juice. Being first means it is the largest single ingredient in the formula, replacing much of the plain water a micellar water would normally contain.

10Camomile

Camomile is one of the oldest plants in skincare. It contains flavonoids, apigenin in particular, and other compounds that calm inflammation in laboratory studies. Most of the research on camomile, though, is about drinking it as a tea or testing extracts in the lab, rather than applying it to skin.

There is one thing to know if your skin is reactive. Camomile belongs to the daisy family (Compositae), along with arnica, calendula and ragweed. A small number of people are sensitised to this plant family, and dermatologists have recorded contact reactions to herbal cosmetics containing it. If daisy-family plants affect you, this product is not for you.

11Linden flower

Organic linden (lime tree) flower extract is traditionally used for its calming, softening feel. It contains flavonoids and mucilage, which can leave skin feeling smooth. We found no human trial of linden extract on skin that we could summarise. We include it as a supporting ingredient and give it no evidence claim.

12A little hyaluronic acid

Sodium hyaluronate, a form of hyaluronic acid, is the last ingredient on the list. That tells you the amount is small. In leave-on creams, hyaluronic acid has good human evidence for hydration, but in a wipe-off cleanser at the bottom of the list, we count it as a small comfort ingredient rather than a reason to buy. We mention it because it is there, and because we would rather you knew its position on the list.

13Preservatives and pH

Anything that contains water needs protecting from bacteria and moulds, especially a product you open and use twice a day. Our micellar water uses sodium levulinate and sodium benzoate, two preservatives allowed under the COSMOS standard. Lactic acid adjusts the pH so it sits close to that of healthy skin, which is slightly acidic.

None of these is an active ingredient. They are there so the product stays safe and stable until the last drop, which is part of what EU cosmetic law requires of every product.

14Fragrance, and why none is declared

The label lists Parfum. That means fragrance is added, and our micellar water is not a fragrance-free product. It has a light, fresh, green scent.

EU law requires certain fragrance ingredients known to cause allergies to be named on the label when they are present above a very low threshold. In 2023 the EU made that list much longer, and the new rules apply to products placed on the market from July 2026. None of the listed allergens, old or new, is in this formula, so none is declared. That makes it a reasonable choice if you react to specific allergens such as linalool or limonene, but not if you avoid fragrance of any kind.

15What COSMOS Organic means here

Our micellar water is certified COSMOS Organic by Ecocert. COSMOS is a European standard for natural and organic cosmetics. It sets rules for where ingredients come from, how they are processed, which preservatives are allowed, and what share of the formula must be organic.

The formula is 99% natural origin and 13% organic origin. Those are percentages of the whole formula as calculated under the standard. Organic aloe juice, camomile and linden are the organic ingredients; glycerin is made using organic ingredients. Certification tells you about sourcing and processing. It says nothing about how well a product cleanses, which is why we give you the research separately.

16Do you need to rinse micellar water?

Micellar water is designed to be left on. That is its convenience. Some dermatologists suggest that people with very reactive skin rinse after using it anyway, so that no cleansing agent stays on the skin for hours. Both approaches are reasonable.

Our advice: if your skin is comfortable after using it, there is no need to rinse. If you notice any tightness or itching, splash your face with lukewarm water afterwards, or follow with a gentle wash on evenings when you have worn heavy makeup or sunscreen.

17Micellar water and double cleansing

Double cleansing means two cleansing steps in the evening: one to remove makeup and sunscreen, one to wash the skin itself. Micellar water makes a good first step. On evenings when you have worn waterproof makeup or a thick sunscreen, follow it with a rinse-off cleanser such as our Sensitive Skin Face & Body Cleanser. On lighter days, the micellar water alone is enough.

In the morning, when there is no makeup to remove, a single pass of micellar water is plenty for most people.

18Which skin types it suits

19Around the eyes

The skin around the eyes is thin, and it is where makeup is usually heaviest. Hold a soaked pad on closed eyes for a few seconds so the micelles can loosen mascara, then wipe downwards and outwards without pulling. If it gets into your eyes, rinse with water. If you wear contact lenses, take them out first.

20How to use it

• Soak a cotton pad well. A dry pad drags; a wet pad glides.
• Hold it on closed eyes for a few seconds, then wipe gently.
• Sweep over the face and lips, turning the pad as it picks up makeup.
• Use a fresh pad until it comes away white.
• Follow with your serum, moisturiser and, in the morning, SPF.

Reusable cotton pads work well too. Wash them after each use.

21Common mistakes

The most common mistake is rubbing. Micellar water works by lifting, not scrubbing, so let the pad do the work. The second is using too little: a half-soaked pad drags on the skin and leaves makeup behind. The third is expecting it to remove waterproof mascara in one pass. Give it a few seconds on closed eyes, or follow with a wash.

22How long a bottle lasts

Most people use two or three millilitres per cleanse. Used morning and evening, a 200 ml bottle lasts around six weeks. At the list price that is well under fifty cents per cleanse. A subscription brings the price down by 10% and delivers free; you can skip or cancel at any time. The details are on the product page.

23Who it suits, and who should skip it

It suits you if you wear makeup most days and want a gentle first cleanse; your skin feels tight after foaming washes; you want to cleanse without a sink; or you want every ingredient named and explained.

Skip it, or check first, if you need a fragrance-free product; you react to camomile or other daisy-family plants; or you want a single step that removes waterproof makeup and heavy sunscreen every night.

24What it adds up to

Our Micellar Cleansing Water is built on the part of cleansing research that matters most: the choice of cleansing agent. It uses glucoside-type cleansers, which irritated skin least in patch testing, alongside betaine, which reduced detergent irritation in a volunteer study, and glycerin and aloe for comfort. It is certified COSMOS Organic and has fourteen ingredients, every one printed on the page.

It doesn't have its own consumer testing, and none of the studies above tested it. What the evidence supports is the approach: less cleansing agent, milder cleansing agents, and no rinsing or rubbing. If that is what your skin needs, this is the product we would point you to.
