Nature Lab Tokyo Perfect Repair Conditioner
Ingredients explained

Also-called: Water | What-it-does: solvent

Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. 

It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. 

What-it-does: emollient, viscosity controlling, emulsifying, emulsion stabilising, surfactant/cleansing | Irritancy: 1 | Comedogenicity: 2

An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%.  

It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols.  Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating and are totally ok for the skin.

What-it-does: emollient | Irritancy: 0 | Comedogenicity: 1

Probably the most common silicone of all. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thick liquid.

As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Also, works well to fill in fine lines and wrinkles and give skin a plump look (of course that is only temporary, but still, it's nice). There are also scar treatment gels out there using dimethicone as their base ingredient. It helps to soften scars and increase their elasticity. 

What-it-does: preservative

We don't have description for this ingredient yet.

Also-called: Castor Oil | What-it-does: emollient, perfuming | Irritancy: 0 | Comedogenicity: 0-1

Castor oil is sourced from the castor bean plant native to tropical areas in Eastern Africa and the Mediterranean Basin. It is an age-old ingredient (it’s over 4,000 years old!) with many uses including as a shoe polish, food additive and motor lubricant. You would be reasonable to think that putting shoe polish on your face wouldn’t be the best idea, but it turns out castor oil has some unique properties that make it a stalwart in thick and gloss-giving formulas (think lipsticks and highlighters).

So what is so special about it? The answer is its main fatty acid, called ricinoleic acid (85-95%).  Unlike other fatty acids, ricinoleic acid has an extra water-loving part (aka -OH group) on its fatty chain that gives Castor Oil several unique properties. First, it is thicker than other oils, then its solubility is different (e.g. dissolves in alcohol but not in mineral oil), and it allows all kinds of chemical modifications other oils do not, hence the lots of Castor oil-derived ingredients. It is also more glossy than other oils, in fact, it creates the highest gloss of all natural oils when applied to the skin. Other than that, it is a very effective emollient and occlusive that reduces skin moisture loss so it is quite common in smaller amounts in moisturizers.

Glucose - goodie
What-it-does: moisturizer/humectant

A fancy name for sugar. Luckily when you put it on your skin it's good for you not like when you eat it. :) It has water-binding properties, which means that it helps to keep your skin nice and hydrated

What-it-does: moisturizer/humectant

Glutamic acid is a little molecule and non-essential (our body can synthesize it) amino acid with the important job of being a neurotransmitter in the human body meaning that it helps your nervous system work correctly. 

As for what it's doing in cosmetics, Glutamic acids' main thing (similar to other amino acids) is being a humectant moisturizer and skin-conditioning agent (sidenote: if you attach lots of glutamic acid molecules, you get polyglutamic acid that is claimed to be a better than hyaluronic acid humectant). It also seems to affect skin barrier repair, however, it is not clear-cut in which direction.

Sodium PCA - goodie
Also-called: Sodium Pyrrolidone Carboxylic Acid | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

PCA stands for Pyrrolidone Carboxylic Acid and though it might not sound like it, it is a thing that can be found naturally in our skin. The sodium salt form of PCA is an important skin-identical ingredient and great natural moisturizer that helps the skin to hold onto water and stay nicely hydrated.

Also-called: Plum Oil, Virgin Prunus Oil | What-it-does: antioxidant, emollient

A straw-yellow to orange-yellow oil coming from the kernels of a native French plum called Ente Plum. According to the manufacturer, the oil is a high-oleic one (about 70% oleic acid and 20% linoleic acid), that makes the oil highly nourishing and moisturizing. It also contains relatively high amounts of antioxidant vitamin E, about 700 ppm that's three times more than in olive oil.

Plum oil also gives the skin an exceptionally silky and nice feeling, penetrates quickly and has a unique natural fragrance. The “top note” is similar to bitter almond, that evolves later to a more complex fruity fragrance. 

Also-called: Argan Oil | What-it-does: antioxidant, emollient

When it comes to cosmetic oils and hype, argan oil is for sure leading the way. Dubbed as the "liquid gold of Morocco", we have to admit we have some trouble determining why this oil enjoys such a special miracle status. Not that it's not good, it is good, even great but reading the research about argan and a bunch of other plant oils we just do not see the big, unique differentiating factor (though that might be our fault not reading enough, obvs.)

So, argan oil comes from the kernel of the argan fruit that comes from the argan tree that grows only in Morocco. The tree is slow growing and getting the oil is a hard job. The traditional process is that the ripe argan fruits fall from the tree, then goats eat them up and poop out the seeds. The seeds are collected and smashed with a stone to get the kernels inside. This part is the hard one as the seeds have extremely hard shells. Once the kernels are obtained, the oil is pressed out from them (the kernels contain about 50% oil).

We don't have description for this ingredient yet.

Also-called: Mango Seed Oil, Mango Seed Butter | What-it-does: emollient

The soft solid, off-white to ivory butter or oil coming from the kernel (the seed inside of the seed) of the Mango. Similar to many other plant oils, it's a great moisturizing and nourishing emollient oil. It has medium spreadability and gives skin a creamy-dry feel. 

It's loaded with a bunch of good-for-the-skin stuff: it contains almost all of the essential amino acids, has several antioxidant phenolic compounds (including famous antioxidant ferulic acid) and is a rich source of nourishing fatty acids (like stearic and oleic acid).

Also-called: Cupuacu Butter

We don't have description for this ingredient yet.

Also-called: Baobab Seed Oil | What-it-does: emollient

Baobab is a really big, iconic tree native to Africa (here is a nice image of it). It's the largest succulent plant in the world and almost all parts of it have traditional medicinal uses in Africa. 

The seed oil, similar to other plant oils, is loaded with things that are good-for-the-skin: it contains skin regenerating vitamin A, antioxidant vitamin E, and vitamin D3 that helps with calcium absorption. It's rich in nourishing fatty acids oleic (30-40%), linoleic (24-34%) and palmitic (18-30%).

We don't have description for this ingredient yet.

Also-called: Marula Seed Oil;Sclerocarya Birrea Seed Oil | What-it-does: emollient

If you have an interest in elephants and Africa, you have probably heard of elephants getting drunk from the fruit of the Marula tree. Though this seems to be only a legend, what is true is that the Marula fruit is really nice (and elephants do love to eat it) and there is a stone in it with several oil-rich kernels inside. 

So the Marula oil - similar to many other plant oils - is a really nice nourishing and moisturizing oil that can improve skin hydration and smoothness and it can even reduce skin redness. It's traditionally used in South Africa to massage babies with and as a body lotion for face, feet, and hands.

Also-called: Prickly Pear Oil | What-it-does: emollient

The emollient plant oil coming from the seeds of the cactus commonly called Prickly Pear or Nopal Fig. It is a native to Mexico cactus with large, sweet fruits that are used to create jam and jellies. About  18–20% of the peeled fruits are seeds, and the seeds contain only about 3-5% oil. This means that the oil is rare and expensive as a ton of fruit (and it is literally a ton) is needed to yield 1 liter of it. 

As for its composition, its three main fatty acids are barrier-repairing linoleic (60-70%), nourishing oleic (9-26%), and saturated fatty acid, palmitic (8-18%). It is also rich in antioxidant vitamin E (110mg/100g) and in anti-inflammatory sterols (beta-sitosterol, campesterol).  As a high-linoleic oil, it has a light skin feeling, absorbs easily into the top layer of the skin and gives a velvety skin feel

What-it-does: emollient, perfuming | Irritancy: 0 | Comedogenicity: 2-4

A super common, medium-spreading emollient ester that gives richness to the formula and a mild feel during rubout. It can be a replacement for mineral oil and is often combined with other emollients to achieve different sensorial properties.

What-it-does: emollient

We don't have description for this ingredient yet.

What-it-does: viscosity controlling

We don't have description for this ingredient yet.

This ingredient name is not according to the INCI-standard. :( What, why?!

It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like. Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-called rheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range. 

Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It’s approved by Ecocert and also used in the food industry (E415). 

Lecithin - goodie
What-it-does: emollient, emulsifying

A very common ingredient that can be found in all cell membranes. In cosmetics it's quite the multi-tasker: it's an emollient and water-binding ingredient but it's also an emulsifier and can be used for stabilization purposes. It's also often used to create liposomes

What-it-does: chelating

We don't have description for this ingredient yet.

What-it-does: preservative

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. 

What-it-does: preservative

A helper ingredient that helps to make the products stay nice longer, aka preservative. It works mainly against fungi. 

It’s pH dependent and works best at acidic pH levels (3-5). It’s not strong enough to be used in itself so it’s always combined with something else, often with potassium sorbate.

Also-called: Fragrance, Parfum;Parfum/Fragrance | What-it-does: perfuming

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-called: Tartrazine, Yellow 5;Ci 19140 | What-it-does: colorant

Ci 19140  or Tartrazine is a super common colorant in skincare, makeup, medicine & food. It’s a synthetic lemon yellow that's used alone or mixed with other colors for special shades. 

FDA says it's possible, but rare, to have an allergic-type reaction to a color additive. As an example, it mentions that Ci 19140 may cause itching and hives in some people but the colorant is always labeled so that you can avoid it if you are sensitive. 

Also-called: Ci 42090 | What-it-does: colorant

CI 42090 or Blue 1 is a super common synthetic colorant in beauty & food. Used alone, it adds a brilliant smurf-like blue color, combined with Tartrazine, it gives the fifty shades of green.

Also-called: Red 33, D&C Red 33, Red 33 Lake;Ci 17200 | What-it-does: colorant | Irritancy: 2 | Comedogenicity: 1

A super common synthetic colorant that adds a purple-red color - similar to red beet - to a product.
