Syndets and Lipid Free Cleansers, What Are They? Do They Work?


You may have come across the term Syndet or `Lipid Free Cleanser’ when researching mild cleansers for your rosacea.

What are theses modern cleansing marvels, and what are you missing by not having them in your daily regime?

What is a Syndet?

Well the term means `Synthetic Detergent’ and is an attempt to create a cleanser that is suitable for the most sensitive of skins. These surfactants (they break the surface of dirt and grime) are made from oils, fats or petroleum, but are not processed by saponification like regular soaps.

What about a Lipid Free Cleanser?

Lipid-free cleansers are soapless liquids that cleanse without water. These products often contain glycerin, cetyl alcohol, and propylene glycol, but they do not contain oils or fats. They leave a thin moisturizing film, and are especially useful for people with sensitive or irritated skin.

Why are Soaps not recommended?

In general a pure soap is not recommended for rosacea sufferers.

A true soap is created by saponification, a process where long-chain fatty acids are combined with an alkali,  resulting in fatty acid salts – what we know as soap.

A true soap is `basic’ on the pH scale which means a value of around 9 to 10, which is far greater than the skin’s pH of 4.5 to 6.5. This means that a soap will change the acid/alkali balance of the skin.

What does skin pH mean?

The pH of the skin is generally in the range 4.5 to 6.5.

pH numbers refer to the acid, neutral or alkaline nature of the skin. The number is a range from 1 to 14, where 1 is highly acidic and 14 is highly basic (or alkali).



Hopefully it is clear from the above picture that it is not a good start to use a product in the 9-10/blue range on skin that is more in the 4-6/orange range.

What will Pure Soap Do to your Skin?

As we are told by Patricia K. Farris MD in `Skin Care Based on Science: Improving Outcomes in Rosacea’ (Cosmetic Dermatology Feb 2012 Vol 23 No. 2), continued use of alkali soaps or cleansers will increase the pH of the skin and cause functional changes such as a disruption of skin lipids, alter the skin flora and could also compromise the skin barrier function.

Thus the aim is to use a cleanser that is slightly acidic or neutral pH.

Also harsh surfactants can damage proteins and disrupt lipids in the stratum corneum and thus contribute to epidermal barrier dysfunction.

What about Combars?

A combination bar is a combination of a true soap and a synthetic detergent. Again they are general pH of 9-10 so are a poor choice for rosacea sufferers.

So what should rosacea sufferers use?

Milder cleansing alternatives that are recommended for rosacea sufferers fall into 2 camps – syndets and lipid-free cleansers.

What is a Syndet made of?

Syndets generally contain less than 10% soap, so can provide a more favourable pH.

Syndets are available as bars or liquids and can commonly contain sodium cocoyl isethionate as well as sulfosuccinates , alpha olefin sulfonates, alkyl glyceryl ether sulfonate, sodium cocoyl monoglyceride sulfate, betaines.

What are Lipid Free Cleansers?

Lipid free cleansers are able to cleans without containing any fat, and like a syndet have a slightly acidic or neutral pH. In general these cleansers do not lather and leave a thin moisturising layer on the skin.

What, No Lather?

Yes that’s right, don’t expect a soothing fluffy lather from these lipid free and syndet liquid cleansers. Say goodbye to that face full of bubbles you used to see in the mirror. You don’t need it, and it may be indicative of a harsh soap.

Article Abstract

Skin Care Based on Science: Improving Outcomes in Rosacea

Cosmet Dermatol. 2012;25:72-78.

Patients with rosacea have compromised skin barrier function and are more prone to dryness, irritation, and skin sensitivity.

With an understanding of the pathogenesis and inherent skin problems that rosacea patients experience, it is essential for dermatologists to provide specific recommendations for skin care.

Cleansers and moisturizers must be selected to improve skin barrier function and reduce inflammation.

Cosmeceuticals with anti-inflammatory actives may be helpful in mitigating the signs and symptoms of rosacea.

This article will review topical skin care products that may improve treatment outcomes in rosacea patients.

    There are so many unpronouncable chemicals on the ingredients list of all these products. I wonder if there is a natural product that could be used as a cleanser? I personally use Clinique redness solutions soothing cleanser to remove makeup, which I find is effective and gentle. Interestingly there is no list of ingredients on the tube.

    • It can be scary to see a long list of ingredients, but don’t be daunted as you can start to make sense of them. It does help if the list of ingredients is short of course.

      Here is is list of ingredients for the Clinque Redness Solutions Soothing Cleanser from here –

      water/aqua/eau, squalane, glycerin, butylene glycol, phenyl trimethicone, ammonium acryloyldimethyltaurate/vp copolymer, avena sativa (oat) kernel extract, cucumis sativus (cucumber) fruit extract, hordeum vulgare (barley) extract/extrait d’orge, sucrose stearate, sea whip extract, cholesterol, helianthus annuus (sunflower) seedcake, chamomilla recutita (matricaria), acetyl glucosamine, ppg-20 methyl glucose ether, caffeine, propylene glycol dicaprate, caprylyl glycol, stearic acid, sodium chloride, disodium edta, bht, phenoxyethanol, polyaminopropyl biguanide, yellow 5 (ci 19140), green 5 (ci 61570), blue 1 (ci 42090).

    what about Neutragena oily face wash with salacylic acid as it’s key ingredient. How harsh is that for the PH levels on rosacea skin? I have been using it for years!

  3. Alicia says:

    What about vanicream? I bought the bar of soap and you can use it on your face these are the ingredients sodium cocoyl isethionate, stearic acid, water, sodium lauroyl sarcosinate, sodium isethionate, sorbitol solution, ceteareth-20, propylene glycol, cetearyl alcohol, glyceryl monostearate, white petrolatum, simethicone, polyethylene glycol monostearate, titanium dioxide, sorbic acid, BHT

  4. Angela says:

    I have used several of these “recommended” liquid cleansers and bars, and I had nothing bur problems with my skin. I have rosacea and acne and all of these caused horrible break outs. Afterward I found a list of comedogenic ingredients online and found several of the ingredients are VERY high on the list of causing acne AND irritation. My advice is to avoid all of these cleansers.

    I am still searching for any cleanser that is compatible with my wretched skn.

  5. Victoria says:

    Cetaphil lotion has actually caused me to have rosacea bumps on the sides of my nose so I switched to just using CeraVe for face wash and face lotion and I don’t have any breakouts. I am also taking Oracea in the morning and using Finacea at night. Still experienceing minor rosacea bumps and redness in/on my cheeks.

  6. Christine Hicks says:

    My Dermotologist recommended PanOxyl bar with benzol peroxide and it has made a huge difference in the acne in my face. It really had made my acne disappear for a long time but my face continues to change as I get older and I now have bad allergies to boot. I use Metro gel and Klaron lotion and take Doxicycline. I am struggling with makeup and moisterizers that don’t break me out and help with sensitive skin.

  7. KC says:

    I love aquanil and have been using it for years. Only cleanser that doesn’t irritate my skin

  8. Elspeth says:

    I have been using Aquanil for 15+ years at my dermatologists recommendation, and its fine for daily cleansing. However it does not not remove the waterproof sunscreen that I wear for outdoor sports a couple of times a week. Doc said to wash it off with shampoo…but I’m not sure that’s a great idea. Can you recommend any facial cleansers that can remove sunscreen but not aggravate Rosacea?

  9. Julie says:

    I had used Cetaphil for many years, but didn’t want to put the parabens included in the ingredients on my skin any longer so I switched to Neutrogena ultra gentle cleanser. It has worked out pretty well.

  10. tbor says:

    Good article. I’ve tried most of these cleansers over the years and currently use Aquanil as it is not irritating and leaves my skin moisturized. Neutrogena Ultra Gentle Cleanser Creamy Formula is actually more moisturizing, but the film it leaves on the skin can cause breakouts, in my case at least. Cerave was moisturizing but something in it was mildly irritating, leaving my skin red. I haven’t had luck with facial bar soaps as they were too drying. So for now it is Aquanil.
