Rohto Mentholatum Acnes Face WashIngredients explained
We don't have description for this ingredient yet.
The salt form of one of the main anti-inflammatory ingredients in the licorice plant, monoammonium glycyrrhizinate. It’s a yellowish powder with a nice sweet smell.
It’s used mainly for its soothing and anti-inflammatory properties, but according to manufacturer info, it’s also sebum regulating so it's a perfect ingredient for problem skin products.

A form of skincare superstar, Vitamin C. If you do not know, what the big deal about Vitamin C is, click here and read all about it, we will wait here for you.
So now you know that pure vitamin C (aka ascorbic acid, AA) is really unstable and hard to formulate so the cosmetics industry is coming up with a bunch of derivatives to solve the problem and Magnesium Ascorbyl Phosphate (or MAP) is one of them.
MAP does solve the stability problem: it's stable up to pH 7, so far so good. What is not so good is that, as the great review study about vitamin C derivatives in the Journal of Cosmetic Dermatology writes, MAP is "at very best, poorly absorbed in comparison to AA."
Moreover, derivatives not only have to be absorbed into the skin, they also have to be converted into pure AA. The good news is that in-vitro data shows that MAP does convert, but the bad news is we do not really know if the same is true on real, living human skin. Even if it does, we don't know how good the conversion rate is (but to be fair the same is true for all other derivatives).
Regarding the three magic abilities of pure vitamin C (antioxidant, collagen booster, skin brightener), there is no published data about MAP's antioxidant or photoprotection capabilities. We have better news about the other two things: in-vitro data shows that MAP can boost collagen synthesis similar to AA (though in the case of AA it's proven in-vivo) and even better, MAP is proven to work as a skin brightener in-vivo (on real people).
Bottom line: when it comes to vitamin C derivatives, MAP is definitely an option. We especially recommend it if you are after skin brightening as this seems to be the strongest point of MAP.
A fatty acid that can be found naturally in the skin. In fact, it's the most common saturated fatty acid found in animals and plants.
As for skincare, it can make the skin feel nice and smooth in moisturizers (emollient) or it can act as a foam building cleansing agent in cleansers. It's also a very popular ingredient in shaving foams.
A 14 carbon length fatty acid that can be naturally found in nutmeg, palm kernel oil, coconut oil and butter fat. It's used as a foam building cleansing agent. Paula Begoun writes that it can be a bit drying to the skin.
A 12 carbon length fatty acid that can be found naturally in coconut milk, coconut oil, laurel oil, and palm kernel oil. It's also in breast milk. As a skincare ingredient, it can be used as an emulsifier or as a cleansing agent.
What's more, there is emerging research about lauric acid being a good anti-acne ingredient. A 2009 study found that the lowest concentration to prevent evil acne-causing P. acnes growth of lauric acid is over 15 times lower than that of gold standard anti-acne ingredient benzoyl peroxide.
Though the studies are only in-vitro (made in the lab, not on real people), and it also has a high comedogenicity index, it might be worth a try if you are prone to inflamed acne (the type that's caused by P. acnes bacteria).
A clear, slightly yellow, odorless oil that's a very common, medium-spreading emollient. It makes the skin feel nice and smooth and works in a wide range of formulas.
It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.
It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.
Other than having a good safety profile and being quite gentle to the skin it has some other advantages too. It can be used in many types of formulations as it has great thermal stability (can be heated up to 85°C) and works on a wide range of pH levels (ph 3-10).
It’s often used together with ethylhexylglycerin as it nicely improves the preservative activity of phenoxyethanol.
Super common ingredient in all kinds of cleansing products: face and body washes, shampoos and foam baths.
Number one reason for its popularity has to do with bubbles. Everyone loves bubbles. And cocamidopropyl betaine is great at stabilizing them.
The other reason is that it’s mild and works very well combined with other cleansing agents and surfactants. The art of cleansing is usually to balance between properly cleansing but not over-cleansing and cocamidopropyl betaine is helpful in pulling off this balance right.
Oh, and one more nice thing: even though it’s synthetic it’s highly biodegradable.

This ingredient name is not according to the INCI-standard. :( What, why?!
It's a very alkaline stuff that helps to set the pH of the cosmetic formula to be just right. It's similar to the more often used sodium hydroxide and pretty much the same of what we wrote there applies here too.
Simply alcohol refers to ethanol and it's a pretty controversial ingredient. It has many instant benefits: it's a great solvent, penetration enhancer, creates cosmetically elegant, light formulas, great astringent and antimicrobial. No wonder it's popular in toners and oily skin formulas.
The downside is that it can be very drying if it's in the first few ingredients on an ingredient list.
Some experts even think that regular exposure to alcohol damages skin barrier and causes inflammation though it's a debated opinion. If you wanna know more, we wrote a more detailed explanation about what's the deal with alcohol in skincare products at alcohol denat. (it's also alcohol, but with some additives to make sure no one drinks it).
An abbreviation that pops up on a lot of ingredient lists. It stands for EthyleneDiamineTetraacetic Acid and it's a famous molecule for being an excellent chelating agent, i.e. a molecule that can bind to metal ions (coming usually from water) and make them harmless in a cosmetic formula. With a chelating agent, cosmetic formulas stay nice longer.
EDTA is an acid molecule and its salt versions are even more often used, such as the super common Disodium EDTA.
Unless you live under a rock, you have probably heard of parabens. Until about 10 years ago they were the most commonly used preservatives, as they are non-irritating, very effective, and cheap.
Then 2004 came and a research paper came out that tested 20 human breast tumors and found parabens in all of them. This was before the era of social media (btw, it's the year Facebook was founded) but this research still managed to go viral and caused parabens to become the evil, cancer-causing preservative in people's head.
Cosmetic companies do want to do what we want to buy and as we did not want to buy products, containing parabens anymore, they started to use alternatives, like the current IT-preservative, phenoxyethanol. It's much easier to replace parabens than trying to go into lengthy explanations about why the 2004 research is misunderstood and how there are lots of data showing that parabens are totally ok.
As people got so interested, the FDA wrote a little article about parabens stating, " (the)FDA believes that at the present time there is no reason for consumers to be concerned about the use of cosmetics containing parabens."
We think the above is pretty much the gist of the topic but if you feel like reading about parabens all day today, here is a handy list for you to get you started:
- Parabens on Wikipedia
- The perils of parabens by cosmetic chemist Perry Romanowski on the great The Beauty Brains blog
- Spotlight on parabens by Nicki Zevola on the Futerederm blog
- Fact-Check Friday: What’s The Deal with Parabens in Cosmetics? on the great LabMuffin blog
A common little helper ingredient that helps water and oil to mix together, aka emulsifier.
Exactly what it sounds: nice smelling stuff put into cosmetic products so that the end product also smells nice. Fragrance in the US and parfum in the EU is a generic term on the ingredient list that is made up of 30 to 50 chemicals on average (but it can have as much as 200 components!).
If you are someone who likes to know what you put on your face then fragrance is not your best friend - there's no way to know what’s really in it.
Also, if your skin is sensitive, fragrance is again not your best friend. It’s the number one cause of contact allergy to cosmetics. It’s definitely a smart thing to avoid with sensitive skin (and fragrance of any type - natural is just as allergic as synthetic, if not worse!).
