The Duo Eyeshadow

Perfectly paired colors with endless blending possibilities. Micronized mineral powder gives this shadow it’s luxurious creamy texture, blending onto the skin with no-drag. The pigment-rich shades stay put all day, [more] [more] as any excess oil on the skin is busily absorbed by the ingredient cornstarch. Build up and blend to a glossy finish with a dry brush, or apply with a moistened brush for an instantly intense sweep of color. [less]

Ingredients explained

Also-called: Cetearyl Octanoate | What-it-does: emollient

A synthetic emollient oil that leaves a soft non-greasy, non-sticky feel on the skin, absorbs fast and can be emulsified (mixed with water) very easily. 

Also-called: Iron Oxide Yellow | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

CI 77492 or Iron Oxide is a common colorant with the pigment yellow.

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

Probably the cheapest and 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. 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.

As for hair care, it is a non-volatile silicone meaning that it stays on the hair rather than evaporates from it and smoothes the hair like no other thing. Depending on your hair type, it can be a bit difficult to wash out and might cause some build-up (btw, this is not true to all silicones, only the non-volatile types). 

What-it-does: abrasive/scrub, absorbent/mattifier | Irritancy: 0 | Comedogenicity: 1

We don't have description for this ingredient yet.

Also-called: CI 77019

A super versatile and common mineral powder that comes in different particle sizes. It is a multi-tasker used to improve skin feel, increase product slip, give the product some light-reflecting properties, enhance skin adhesion or serve as an anti-caking agent. Popular both in makeup and in skin care products. 

A white powdery thing that's the major component of glass and sand. In cosmetics, it’s often in products that are supposed to keep your skin matte as it has great oil-absorbing abilities. It’s also used as a helper ingredient to thicken up products or suspend insoluble particles. 

What-it-does: viscosity controlling

An  odorless, slightly yellowish powder that's used as a polymer microsphere (a tiny little ball from repeated subunits). It gives products an elegant, silky texture and better slip. It can also scatter light to blur fine lines while letting enough light through so that the skin still looks natural.

Also-called: Iron Oxide Black | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

CI 77499 or Iron Oxide is a super common colorant with the color black. 

Also-called: titanium dioxide/ci 77891 | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Ci 77891 is the color code of titanium dioxide. It's a white pigment with great color consistency and dispersibility.

Also-called: Iron Oxide Red | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

CI 77491 or Iron Oxide is a super common colorant  with the color red. 

Also-called: Corn Starch;Zea Mays Starch | What-it-does: viscosity controlling, absorbent/mattifier

A corn-derived, white to yellowish, floury powder that works as a handy helper ingredient to create nice feeling emulsions.

It gives a generally pleasant skin feel, has some mattifying effect (though rice starch is better at that), it reduces greasiness and tackiness and helps the formula to spread easily without whitening or shininess. 

What-it-does: viscosity controlling, absorbent/mattifier | Irritancy: 0 | Comedogenicity: 0

A type of clay mineral that works as a nice helper ingredient to thicken and stabilize formulas. As a clay, it consists of platelets that have a negative charge on the surface (face) and a positive on the edge. So the face of one platelet attracts the edge of the other and this builds a so-called "house of card" structure meaning that Magnesium Aluminum Silicate (MAS) thickens up products and helps to suspend non-soluble particles such as color pigments or inorganic sunscreens (zinc oxide and titanium dioxide).

As the "house of card" structure takes some time to form but collapses quickly if the formula is stirred, products thickened with MAS can be thick in the jar but become easily spreadable upon application (called thixotropy). MAS also gives nice sensory properties, it is not tacky or sticky and gives a rich, creamy skin feel. Also a good team player and works in synergy with other thickeners such as Cellulose Gum or Xanthan Gum

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.

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. 

What-it-does: preservative

If you have spotted ethylhexylglycerin on the ingredient list, most probably you will see there also the current IT-preservative, phenoxyethanol. They are good friends because ethylhexylglycerin can boost the effectiveness of phenoxyethanol (and other preservatives) and as an added bonus it feels nice on the skin too.

Also, it's an effective deodorant and a medium spreading emollient

What-it-does: solvent

A really multi-functional helper ingredient that can do several things in a skincare product: it can bring a soft and pleasant feel to the formula, it can act as a humectant and emollient, it can be a solvent for some other ingredients (for example it can help to stabilize perfumes in watery products) and it can also help to disperse pigments more evenly in makeup products. And that is still not all: it can also boost the antimicrobial activity of preservatives

It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol

The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.

What-it-does: viscosity controlling

We don't have description for this ingredient yet.

What-it-does: emollient, viscosity controlling | Irritancy: 0 | Comedogenicity: 2-3

A common multi-tasker fatty acid. It makes your skin feel nice and smooth (emollient), gives body to cream type products and helps to stabilize water and oil mixes (aka emulsions).

What-it-does: skin-identical ingredient, emollient, emulsifying | Irritancy: 0 | Comedogenicity: 2

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. 

Lauric Acid - goodie
What-it-does: anti-acne, surfactant/cleansing, emulsifying | Irritancy: 1 | Comedogenicity: 4

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).

What-it-does: preservative

A pale yellow solid material that helps cosmetic products not to go wrong too soon aka preservative.

It has antioxidant and antibacterial activity and can be used synergistically with IT-preservative phenoxyethanol or 1,2-Hexanediol and Caprylyl Glycol to form a broad spectrum preservative system for cosmetic formulas.
