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. 

Also-called: Aloe Vera | What-it-does: soothing, moisturizer/humectant

Aloe Vera is one of today’s magic plants. It does have some very nice properties indeed, though famous dermatologist Leslie Baumann warns us in her book that most of the evidence is anecdotal and the plant might be a bit overhyped.

What research does confirm about Aloe is that it’s a great moisturizer and has several anti-inflammatory (among others contains salicylates, polysaccharides, magnesium lactate and C-glucosyl chromone) as well as some antibacterial components. It also helps wound healing and skin regeneration in general. All in all definitely a goodie. 

A vegetable origin (coconut or palm kernel oil and glucose) cleansing agent with great foaming abilities. It's also mild to the skin and readily biodegradable.

What-it-does: surfactant/cleansing

A 100% vegetable origin, biodegradable, mild cleansing agent that gives moderate to high amount of foam. It's happy to work together with other surfactants (in general, that helps to create milder formulas). 

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). 

What-it-does: preservative

It's one of those things that help your cosmetics not to go wrong too soon, aka a preservative. It’s not a strong one and doesn’t really work against bacteria, but more against mold and yeast. To do that it has to break down to its active form, sorbic acid. For that to happen, there has to be water in the product and the right pH value (pH 3-4). 

But even if everything is right, it’s not enough on its own. If you see potassium sorbate you should see some other preservative next to it too.

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.

What-it-does: buffering

Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA. 

So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh. 

Also-called: Black Cumin Oil;Nigella Sativa Seed Oil | What-it-does: soothing, antioxidant, emollient, perfuming

The (fixed or non-volatile) oil coming from the black seeds of Nigella Sativa, a smallish (20-30 cm) flowering plant native to Southwest Asia. The seed has a very complex chemical composition (it contains both fixed and volatile oil) and is used traditionally for a bunch of "anti-something" abilities including antitumor, antidiabetic, antihistaminic, anti-inflammatory, and antimicrobial properties. In Islam, black cumin seed was considered "a healing seed for all diseases except death”.  

As for modern research and chemical composition, the fixed oil from the seeds is rich in skin-nourishing unsaturated fatty acids (mainly linoleic acid at 50 – 60% and oleic acid at 20%, but also contains some rare ones like C20:2 arachidic and eicosadienoic acids), amino acids, vitamins, and minerals. A component called thymoquinone (it's the main component of the volatile oil part, but the fixed oil also contains some) is considered to give the seed its main therapeutic properties including strong antioxidant and anti-inflammatory abilities.

We don't have description for this ingredient yet.

Also-called: Peppermint Oil;Mentha Piperita Oil | What-it-does: perfuming

The essential oil coming from steam distillation of freshly harvested, flowering peppermint sprigs. Its major component is menthol that gives the oil its well-known refreshing and cooling properties. Peppermint oil is traditionally used as an inhalant for cold and coughs and there is also some clinical data validating its use against headaches by rubbing a peppermint oil cream on the forehead. 

As for skincare, other than the nice grassy-minty smell and the refreshing sensations, we cannot write good things. It can be a skin irritant, so much so that it is a well-known counterirritant for muscle pains creating mild surface irritation to make things better in the deeper layers. But for everyday skincare, counterirritation is not something you wanna do, so we think that peppermint oil is better to avoid, especially if your skin is sensitive. 

Also-called: Eucalyptus Essential Oil;Eucalyptus Globulus Leaf Oil | What-it-does: perfuming, antimicrobial/antibacterial

The essential oil created by steam distilling the leaves of the Eucalyptus tree. It's a colorless, pale yellow oil with a camphoraceous aroma used traditionally in vapor rubs to treat coughs. Its name-giving main component is eucalyptol (also called 1,8-cineole, 80-91%) that has significant antibacterial and expectorant properties.   

Among essential oils, Eucalyptus Globulus counts as rather non-sensitising with an EU sensitizer total of 5% (due to limonene). However, if your skin is super-sensitive or you are allergic to fragrances, it is still better to avoid it.
