Skin Juice Star QuencherIngredients explained
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.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
Squalene is an oily liquid that originally comes from shark liver but luckily it can also be found in a couple of plant oils. Olive (0.6%), peanut (0.1%) and pumpkin (0.35%) oils contain it, though not in huge amounts.
What contains more of it, is the sebum (the oily stuff) that our skin produces. About 13% of human sebum is squalene, which means that it’s an important skin-identical ingredient and NMF (natural moisturizing factor).
Chemically speaking, it is an unsaturated (has double bonds) hydrocarbon (contains only carbon and hydrogen) molecule, that can undergo oxidation. On the pro side, this means that squalene can act as an antioxidant (while its no-double-bond version sister, squalane cannot), but on the con side, squalene is less stable and has a shorter shelf life.
This is probably the main reason why its no-double bond and hence more stable sister, squalane shows up more often on ingredient lists. Read about squalane here >>
A super common emollient that makes your skin feel nice and smooth. It comes from coconut oil and glycerin, it’s light-textured, clear, odorless and non-greasy. It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type and easy to formulate with. No wonder it’s popular.
A so-called fatty (the good, non-drying kind of) alcohol that does all kinds of things in a skincare product: it makes your skin feel smooth and nice (emollient), helps to thicken up products and also helps water and oil to blend (emulsifier). Can be derived from coconut or palm kernel oil.
The emollient plant oil coming from the kernel (the seed of the seed) of the delicious apricot fruit. Like other plant oils, it contains antioxidant vitamin E and nourishing fatty acids (mostly oleic acid 54-74%, linoleic acid 12-35%).
It's a nice general purpose emollient, has nourishing and moisturizing properties (as a high oleic oil it's ideal for dry skin types) and is quite easily absorbed into the skin.
The golden yellow oil coming from the Macadamia nut, a native Australian nut. Similar to other plant oils, it's loaded with emollient and nourishing fatty acids. It's a high oleic acid oil (50-67% oleic acid and only 0-5% linoleic acid) that makes it very emollient and ideal for dry skin types (and less ideal for acne-prone skin).
Its unique property is that it contains high amounts of a rare fatty acid called palmitoleic acid (12-25%) that give Macadamia oil a "cushiony" feel. It's also easily absorbed and makes the skin soft and supple.
- A natural moisturizer that’s also in our skin
- A super common, safe, effective and cheap molecule used for more than 50 years
- Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
- Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
- High-glycerin moisturizers are awesome for treating severely dry skin
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.
A sugar based emulsifier that's especially great for low viscosity lotions or even sprays. It's effective in small amounts, only 1-1.5% is needed to form an emulsion. The resulting cream or lotion has great cosmetic properties with good spreadability and an enhanced soft skin feel.

Prickly pear is a cactus that’s native to Mexico. It has large, sweet fruit that’s called tunas and has been used as a source of food since pre-Hispanic Mexico. Currently jams and jellies are produced from it and also a traditional Mexican alcoholic drink called colonche.
But what is it doing in our skincare products? Well, according to swiss manufacturer, Mibelle its two main properties are that it soothes and hydrates the skin. And what’s more, they have also created some nice test results both in vitro and in vivo (in the lab tubes and on humans) showing that Opuntia Ficus-Indica can protect skin cells against UV light.
And that’s still not all. An American manufacturer has combined the ingredient with yeast extract and the two together helps to reduce neurosensory irritation caused by the application of topical products such as retinoids (slow reaction), alpha hydroxy acids (fast reaction) or preservatives which induce some type of irritation or inflammation.
The bottom line: though we could not really find independent published research, we definitely think that Prickly Pear’s name sounds cool + it’s a very promising ingredient that seems to have great soothing and protecting abilities.
Super common soothing ingredient. It can be found naturally in the roots & leaves of the comfrey plant, but more often than not what's in the cosmetic products is produced synthetically.
It's not only soothing but it' also skin-softening and protecting and can promote wound healing.
- Primary fat-soluble antioxidant in our skin
- Significant photoprotection against UVB rays
- Vit C + Vit E work in synergy and provide great photoprotection
- Has emollient properties
- Easy to formulate, stable and relatively inexpensive
A yellow-greenish oil coming from the seeds of Cranberry. Similar to other emollient plant oils, it is loaded with nice fatty acids. It contains a very balanced 1:1 ratio of anti-inflammatory omega-3 (aka linolenic acid) and barrier repairing omega-6 (aka linoleic acid) (30-38%), and also a decent amount of skin-nourishing omega-9, aka oleic acid. It also has high vitamin E content and significant antioxidant properties.
Other than being a nice emollient plant oil, we also found a research showing that cranberry oil has wound-healing potential.
An amino acid-based emulsifier that helps water and oil to mix and stay that way. It is considered as natural, environmentally friendly, and hypoallergenic.
The extract coming from the juice containing leaves of the Aloe vera plant. It's usually a hydroglycolic extract (though oil extract for the lipid parts also exists) that has similar moisturizing, emollient and anti-inflammatory properties as the juice itself. We have written some more about aloe here.
It’s one of those little helper ingredients that makes sure the product stays the same over time. No color change or anything like that. It does so by neutralizing the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.
It is a type of algae extract coming from the algae commonly called Irish moss or red seaweed. It is rich in carrageenan, a natural polymer (big molecules from repeated subunits) that acts as a gelling, thickening and stabilizing agent.
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).
Though it says fruit oil in its name, the rosehip fruit contains the seeds that contain the oil. So this one is the same as Rosa Canina Seed Oil, or Rosehip Oil, known for its high omega fatty acid content (linoleic acid - 51%, linolenic acid - 19% and oleic acid - 20%) and skin-regenerative properties.
There is a common misconception that rosehip oil contains vitamin C as the fruit itself does, but vitamin C is a water-soluble vitamin hence it is not contained in the oil. The antioxidant and regenerative properties of the oil probably come from the oil-soluble tocopherols (vitamin E) and carotenoids (pro-vitamin A). Read more here.

Sunflower does not need a big intro as you probably use it in the kitchen as cooking oil, or you munch on the seeds as a healthy snack or you adore its big, beautiful yellow flower during the summer - or you do all of these and probably even more. And by even more we mean putting it all over your face as sunflower oil is one of the most commonly used plant oils in skincare.
It’s a real oldie: expressed directly from the seeds, the oil is used not for hundreds but thousands of years. According to The National Sunflower Association, there is evidence that both the plant and its oil were used by American Indians in the area of Arizona and New Mexico about 3000 BC. Do the math: it's more than 5000 years – definitely an oldie.
Our intro did get pretty big after all (sorry for that), so let's get to the point finally: sunflower oil - similar to other plant oils - is a great emollient that makes the skin smooth and nice and helps to keep it hydrated. It also protects the surface of the skin and enhances the damaged or irritated skin barrier. Leslie Bauman notes in Cosmetic Dermatology that one application of sunflower oil significantly speeds up the recovery of the skin barrier within an hour and sustains the results 5 hours after using it.
It's also loaded with fatty acids (mostly linoleic (50-74%) and oleic (14-35%)). The unrefined version (be sure to use that on your skin!) is especially high in linoleic acid that is great even for acne-prone skin. Its comedogen index is 0, meaning that it's pretty much an all skin-type oil.
Truth be told, there are many great plant oils and sunflower oil is definitely one of them.
The essential oil coming from the second most common type of chamomile, the Roman Chamomile. It also contains the biologically active anti-inflammatory components, bisabolol, and chamazulene, but less than the more commonly used German Chamomile. It's not clear what Roman Chamomile knows that the German one does not.

- It’s the second most researched AHA after glycolic acid
- It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
- It also has amazing skin hydrating properties
- In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles
- Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
- Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)
The essential oil coming from the peel of the mandarin orange or tangor. In general, the main component of citrus peel oils is limonene (77-86% for mandarin peel), a super common fragrant ingredient that makes everything smell nice (but counts as a frequent skin sensitizer). Apart from smelling nice (and thus being a popular natural fragrance alternative), Mandarin Orange Oil also has significant antioxidant properties that's comparable to synthetic antioxidant BHT or oil-soluble antioxidant big shot vitamin E.
On the con side, the fragrant components of citrus peels might irritate sensitive skin and citrus peels also contain the problematic compound called furanocoumarin that makes them (mildly) phototoxic. Orange mandarin peel contains less from it than some other citruses (like bergamot or lime), but still, be careful with it especially if it's in a product for daytime use.
It's one of those things that help your cosmetics not to go wrong too soon, aka a preservative. It can be naturally found in fruits and teas but can also be made synthetically.
No matter the origin, in small amounts (up to 1%) it’s a nice, gentle preservative. Has to be combined with some other nice preservatives, like potassium sorbate to be broad spectrum enough.
In high amounts, it can be a skin irritant, but don’t worry, it’s never used in high amounts.
- It's one of the gold standard ingredients for treating problem skin
- It can exfoliate skin both on the surface and in the pores
- It's a potent anti-inflammatory agent
- It's more effective for treating blackheads than acne
- For acne combine it with antibacterial agents like benzoyl peroxide or azelaic acid
A mild, natural preservative that usually comes to the formula together with its other mild preservative friends, such as Benzoic Acid and/or Dehydroacetic Acid. Btw, it's also used as a food preservative.
A natural, soluble colorant (aka dye) that comes from the seeds of the annatto bush. It gives an orange hue.
