Are ceramides good anti-aging ingredients? Episode 77

Do you wonder which anti-aging ingredients really work? Today we’re reviewing the evidence for ceramides.

Ceramides

Which anti-aging ingredients really work?

When it comes to anti-aging products it’s easy to be tricked into spending a lot of money on products that aren’t worth it. That’s because there’s so much pseudoscientific misinformation out there about anti-aging cosmetic ingredients. Also, once you buy an anti-aging product, it takes you a long time to determine if it’s really working for you or not. That’s why we’re going to focus some of our podcast episodes on specific anti-aging ingredients, Today we’re talking about ceramides.

What are ceramides?

“Ceramide” is one of those buzzwords that gets thrown around a lot in the beauty industry, especially with regard to anti-aging. But I’ve never seen a good explanation of what a ceramide is, what it really does, and what to look for in a product. That’s what we’re going to cover today, starting with a little chemical background…

Ceramides are a special type of oily wax that’s naturally found in our skin (and other places.) In fact, the word ceramide comes from the Latin cera which means wax. Ceramides form a kind of water-proofing barrier in the upper layers of skin. They’re not only critical for helping skin retain water but they also help repair the skin’s natural barrier and regulate cells. Ceramide production dwindles with age which can result in dry skin, wrinkles and even some types of dermatitis.

Did you know that newborn infants, especially premature ones, may be born with a waxy or cheese-like coating on their skin that prevents them from losing too much moisture? That coating is called the vernix caseosa and it is composed, primarily, of ceramides.

Chemically speaking, ceramides consist of a long-chain or sphingoid base linked to a fatty acid. By the way, “sphingoid bases” were first discovered in brain fluid and they’re named after the Sphinx because the chemist who found thought them thought they had an “enigmatic structure.” Anyway, sphingoids make up about half of a ceramide. Therefore, ceramides are not a single thing – different types of ceramides can be made depending on which specific base and which fatty acid are combined. There are at least 9 different types of ceramides found naturally. To make things even more confusing there are not only ceramides but phytoceramides, psuedoceramides, and synthetic ceramides. So let’s define these before we go any further.

  • Ceramide: A waxy lipid that is occurs naturally in skin. It’s made by combining combine a fatty acid with a sphingoid base.
  • Phytoceramide: A ceramide made with a phytosphingosine (a special type of sphingosine found in yeast, plants and some mammalian tissues. Don’t get tricked by this because “Phyto” is a buzz word for made from plants so this sounds like a cool, green ingredient. In reality its sourced from yeast.)
  • Pseudo-ceramide: A lipid that has similar properties to a ceramide but which has a different structure. For example, Ceramide E is a pseudo-ceramide. Another example is Arachamide MEA. Pseudo-ceramides may be naturally occurring but typically are made synthetically.
  • Synthetic ceramide: A lab-created version of a ceramide found in nature.
  • For the most part, ceramides used in skin care are synthetic (whether they are true ceramides or pseudoceramides.) Ceramides can be sourced naturally but they are present at only low concentrations in plants and animals so naturally derived ceramides are expensive. And besides, based on what we’ve seen, it doesn’t matter if the ceramide is natural or synthetic as long as it has the right structure.

Understanding ceramide nomenclature

Understanding which ceramides are used in cosmetics is confusing because there are three different ways they can be named:

1. The original INCI name which simply refers to each ceramide by a number.

2. The revised INCI name (sometimes called the “Motta” system) which uses a three letter designation. The first letter is the type of amide-linked fatty acid. (N stands for Normal Fatty acid. A stands for Alphahydroxy fatty acid and O stands for Omega hydroxy fatty acid.) The second letter is the type of base. (S stands for Sphinogsine base, P stands for Phytosphingosine base and H stands for Hydroxysphingosine base.) If there’s an “E” in front of the two letters then that means it’s an ester linked fatty acid.

3. Some times the chemical name of the ceramide is used (which doesn’t include the word ceramide at all.)

What to look for on the label:

  • Ceramide 1 = Ceramide EOS
  • Ceramide 2 = Cermamide NS = N-stearoyl sphinganine
  • Ceramide 3 = Ceramide NP = N-stearoyl phytosphingosine
  • Ceramide 4 = Ceramide EOH
  • Ceramide 5 = Ceramide AS
  • Ceramide 6 = Ceramide AP = α-hydroxy-N-stearoylphytosphingosine
  • Ceramide 6 II = Caproyl sphingosine
  • Ceramide 7 = Ceramide AH
  • Ceramide 8 = Ceramide NH
  • Ceramide 9 = Ceramide EOP
  • Ceramide E = Cetyl-PG Hydroxyethyl Palmitamide and Hexadecanamide

Now that you know what ceramides are and how to spot them on your product labels, let’s talk about what these things really do for skin. Are they worth the hype?

Ingested ceramides for skin

We’re going to focus our discussion on topically applied ceramides but I want to quickly touch on ingested ceramides. If you’ve listened to our previous anti-aging spotlights on collagen and hyaluronic acid you know we looked at the data for ingesting those materials to help your skin. For ceramides there is SMALL amount of research that shows they can improve the skin barrier when swallowed. A company called Hitex that makes phytoceramide capsules conducted their own study that showed a “perceived” improvement in dry skin.  Another study showed that taking 20mg or 40mg/daily for 3 weeks decreased transepidermal water loss (TEWL) and increased skin moisture content compared to a placebo.  And, for what it’s worth, the FDA has published a paper which essentially says phytoceramides are safe to ingest and that they’ve never seen any problems from dietary supplements that contain them. That, however, doesn’t mean they’ve actually been proven to work. ”New Dietary Ingredient Notification: For Phyto-Derived Ceramides.”  There just doesn’t seem to be as much as a push for ingestible ceramides like we’ve seen with collagen.

Ceramides as topical moisturizers

Overall, topical application is much better studied and that’s where the majority of interest is in the beauty biz so let’s get to that.

As always we’ll be using the 3 Kligman questions as a framework: is there a scientific mechanism to explain HOW ceramides work? Do ceramides penetrate into the skin where they COULD work? And are there any legitimate studies on real people showing ceramides DO work?

Is there a mechanism?
It’s well understood that natural ceramides waterproof skin. Furthermore, we know they do this best when they’re combined with other oily materials in a specific ratio. The optimal mixture of 50% ceramides, 25% cholesterol, and 15% free fatty acids forms what are called “crystalline lamellar structures” which have unique moisture retaining properties. So yes, there is a mechanism for how ceramides benefit skin.

Do they penetrate?
Yes they do and it’s not surprising given that ceramides are “skin identical” lipids. This is not some foreign ingredient, it’s one that’s naturally present in the upper layers of skin. It’s been proven that topically applied ceramides can move into the upper layers of the stratum corneum by a method called tape stripping. We’ve talked about this method before – essentially it involves sticking a piece of tape on your skin, ripping it off, and then analyzing it for the ingredient that you’re looking for. Each time you do this you tear off a few more layers of skin cells so by repeated tape stripping you can get a sense of how far an ingredient penetrates into the stratum corneum. Here are two quick examples:

Friend of the Brains Dr. Zoe Draelos published one such study. Cosmetics and Dermatologic Problems and Solutions, Third Edition By Zoe Diana Draelos. Another source confirms that finding but, interestingly, the degree of penetration may depend on what else is in the formula. The Textbook of Cosmetic Dermatology says that without a glyceryl ether the ceramides weren’t any better than the placebo.

Are there studies proving they work?
There a numerous studies on the efficacy of ceramide creams but there are two problems to watch out for. First, a number of the studies are “open label” which means they’re not blinded and there’s no control. So even if they show that ceramide cream does work you can’t tell if the cream without the ceramides would have worked just as well! The second problem is that there are so many different types of ceramides, that can be used at different levels, in combination with so many other materials that’s it’s impossible to pinpoint a definitive study showing what works “best.” Despite these problems, though, the weight of the evidence makes it apparent that ceramides can be beneficial. We’ll cite a few example studies to give you a flavor of the work that’s been done.

  • A study published in the J Clin Exp Dermatol shows that topical ceramides not only repair the skin barrier but they actually protect it from future attack by surfactants. (This study was done on mice.)
  • A Japanese study shows that plant-derived ceramides improve skin moisture better than a placebo.
  • The Kao Corporation published a study showing that a cream containing 8% of Ceramide E improves water content of skin and symptoms of atopic dermatitis. But, ceramide cream wasn’t compared to any other product. So the test had no control and it wasn’t blinded. By the way, this 8% concentration shows up in a couple of studies and it’s MUCH higher than the typical use level of ceramides which is a few tenths of a percent.
  • According to the Textbook of Cosmetic Dermatology, certain ceramide combinations are better than a placebo at repairing skin barrier function.
  • And a paper titled “Skin-identical lipids versus petrolatum” shows that ceramides work but they aren’t any better than petrolatum. They tested a blend of ceramide-3, cholesterol, oleic acid and palmitic acid and they say the lack of superiority may be due to a “suboptimal lipid mixture.” Again, it’s this notion that you have to have the right blend at the right ratio for ceramides to perform their best.

There are many more of these studies so it appears there is ample evidence that ceramides really do work.

Let me very quickly interject a note about a completely different approach. Instead of restoring ceramides you’ve lost, you can protect the ceramides you already have. There are enzymes in your skin called ceramid-ases that break down these lipids so if you can limit these enzymes theoretically you can keep more ceramides in your skin. I found one research paper on this topic and apparently it’s a little bit tricky because of the difficulty in sourcing these enzymes. Researchers can’t get them out of skin very easily so instead they get them from…get this…fecal extracts and nasal secretions.

So, anyway, now that we know ceramides really work what does this all mean if you want to buy an anti-aging ceramide cream?

How to pick the ceramide cream that’s right for you

First, let me summarize why picking a ceramide cream is so complicated:

1. There are many different types of ceramides. But at least most of them (at least the ones commonly used) appear to be beneficial to skin.

2. Sometimes they’re beneficial because they are just providing an occlusive layer on the surface of skin that locks in moisture. If that’s the case, ceramides may work no better than conventional, less expensive ingredients like petrolatum.

3. Other times they’re MORE beneficial because they’re penetrating and moisturizing from within. This means they may have a more prolonged effect compared to conventional ingredients. However, this seems to be the case only when the ceramides are combined with other materials like cholesterol and fatty acids. AND, they have to be combined in very specific ratios. For example, in skin the natural ratio is 3.6 to 1.2 to 1. We found one patented product that uses a ratio of 3:1:1. And who know what ratios other products use – but we do know it’s critical. Unfortunately we could find no side by side studies to prove which products are best. Which means that it’s very difficult for you to know if any given product is worth trying, especially if it’s expensive.

So, if you want add ceramides to your anti-aging regimen, here’s what we recommend: Start cheap and work your way up. To help you get started, we’ll list a few products starting with the inexpensive ones that may only have a single ceramide followed by more costly ones that appear to contain the optimal blend of actives (hopefully at the right ratio.) Try the cheapest one first. If you don’t like the way that one makes your skin feel, go up to the next most expensive one and continue the process until you find one you like.

The Beauty Brains bottom line

“Ceramides” refers to a class of ingredients which are waxy lipids naturally found in skin.

Ceramides are good moisturizers but may be not better than regular lotions unless correctly formulated.

The best formulas blend ceramides with cholesterol and fatty acids to replicate skin’s natural moisture barrier.

To save money, start with the least expensive ceramide creams and work your way up until you find one you like.

Improbable Products

We also played the Improbable Products game in this week’s show. Can you guess which of these three products is just made up? (Listen to the show for the answer.)

1. Robo manicurist
If you like the look of well manicured nails but you’re too lazy to do it yourself, you’re in luck! A Japanese company has invented a robot designed to paint your nails.

2. Smart sock
Anyone who’s suffered from calluses will love this new salicylic acid impregnated sock that treats your feet while you walk.

3. Moisture monitor
Researchers have developed a sensor that detects when your skin is dry and alerts you to apply more lotion.

    Great post! So many companies say that their creams and lotions have ceramides when touting their anti-aging benefits, but that’s pretty much where the discussion ends. You did a wonderful job of explaining about the different types and the role they play in protecting the skin. I was especially interested in the information about the importance of ratio when determining the efficacy. Unless the product is properly formulated, “ceramides” becomes just another buzz-word in the anti-aging lexicon.

  • Andrea Fitch April 7, 2015, 3:55 pm

    Have you ever tried Anew Clinical Thermafirm?http://avon4.me/1INiAkb. You can see the ingredients and reveiws at my website. My customers are raving about this product.

      This one appears to be worth trying.

      • LaDonna Pulsipher May 2, 2015, 6:08 pm

        Fabulous! Thanks for the reply and love the podcast!

  • Pedro April 12, 2015, 11:14 pm

    I believe some creams from Kao can have about 8% of ceramides because in many cases the “pseudo-ceramide” is the third ingredient in the list… Another interesting point is that Kao has published some studies showing eucalyptus extract can stimulate the skin produce its own ceramides:

    1 – http://www.ncbi.nlm.nih.gov/pubmed/19156331

    2 – http://www.ncbi.nlm.nih.gov/pubmed/21696405

    3 – http://www.ncbi.nlm.nih.gov/pubmed/23438136

    • Randy Schueller April 13, 2015, 12:33 pm

      Very interesting about the eucalyptus oil!

      • Curious May 9, 2016, 12:02 pm

        These studies talk about eucalyptus extract, but you mention eucalyptus oil in your comment. Will a topically applied eucalyptus essential oil produce some results?

  • Pedro April 14, 2015, 5:29 am

    Still talking about the ceramides from Kao: they claim they use an emulsification technique in almost all of their emulsions that creates structures similar to the skin’s ceramides…

    http://www.kao.com/jp/en/corp_rd/development_00_00.html

    • Randy Schueller April 14, 2015, 9:23 am

      Yeah, apparently the structure of the lipid bilayers is important in determining transepidermal water loss.

  • Ariel August 3, 2015, 5:01 pm

    Thanks for the useful information! This website is like no other!
    One question ; The Cerave Moisturizing lotion you mentioned above has only 0.2% of Ceramides, 0.007% of Cholesterol and 0.001% of Hyaluronic Acid (Which the local distributor here in Korea just told me). Do you think it is still worth a try?

    • Randy Schueller August 3, 2015, 7:08 pm

      Hmmm. Those levels sound really low. Are you sure the distributor has access to the actual formula percentages?

      • Ariel August 4, 2015, 8:32 pm

        Yes. Because they are the authorized exclusive distributor, they must know the actual formula percentage to label the ingredients list in Korean. They even changed the order of some ingredients to comply with the Korean labeling requirements (Ceramides are far below close to the end). I did some research on ceramides and found an information sheet written by a manufacturer. It says its efficacy starts from 0.05 % and the recommended concentration is 0.05 to 1%. But I can’t trust it because it’s not based on scientific studies. Cosmetics companies say more than 1% is high concentration. The highest I found is 3%. But I still wonder. If ceramide is no better than petrolatum, and it doesn’t work like natural lipids without cholesterol and fatty acids, isn’t it just a bogus ingredient the cosmetics industry exaggerate and fantasize about?

  • aligena September 25, 2015, 3:13 pm

    So do all ceramides act as occlusives, assuming they’re in the right ratios? I ask because I wonder if I should layer anything over them.

    • Randy Schueller September 26, 2015, 7:48 am

      Layering is a good idea. I haven’t seen anything to suggest that ceramides alone are adequately occlusive.

  • Ellen Turner March 9, 2016, 3:17 am

    I had ceremide cream and hydroxacel eye effect advanced eye treatment along with it. I have been cleansing and toning my skin twice a day and applied each of these products for 20 days now, I have seen a noticeable difference in my face skin. I am impressed with these products and it only cost me $10.00 dollars total. I will be having more sent to me within the next 2 weeks. I have been using an Avon face cream for the last 25 years with no positive effect except to moisturize my skin, it is called Avon Platinum cream and also in the past Avon Anex Cream. I am now 60 years old and so I reached out for something different that would help me improve my skin with my crows feet and parenthesis on my face and what have you. Anyway, I guess bottom line is to convey to other women the good experience I have had, I look forward to more information from you and the newsletter I have applied to. Thank you for your time and feel free to share my email with others. Sincerely, Ellen Turner Reyes

  • Deanna August 8, 2016, 6:25 pm

    Thank you! so much for your article on Ceramides I have dermatitis the information was invaluable. Is there an anti ageing moisturizer for my face that Has a lot of Ceramide in the ingredients but is organic and chemical free?
    Thank you Kindly,
    Deanna from Australia

  • Charlotte G August 23, 2016, 7:45 am

    Hi Randy.
    You mentioned that you knew of one patented product that uses the ratio of 3:1:1. Which brand was it?
