Dermalogica Barrier Defense Booster
Ingredients explained

Also-called: Cotton Seed Oil | Irritancy: 2 | Comedogenicity: 3

We don't have description for this ingredient yet.

Also-called: Crambe Oil | What-it-does: emollient

The emollient plant oil coming from the seeds of Crambe Abyssinica, a not very well-known plant native to the Ethiopian Highlands. It has a unique fatty acid profile and contains high amounts of erucic acid (50-65%), a 22 carbon long unsaturated fatty acid. 

The oil is described as having an elegant, silky and cushioning skin feel, kind of silicone-like. Also ideal for hair-care as it gives slip, softness, and shine to the hair. 

Also-called: Grape Seed Oil | What-it-does: antioxidant, emollient | Comedogenicity: 2-3

A goodie plant oil coming from the polyphenol-rich seeds of the grape. It's a light emollient oil that makes your skin feel smooth and nice and also contains a bunch of good-for-the-skin stuff. It's a great source of antioxidant polyphenols, barrier repair fatty acid linoleic acid (about 55-77%, while oleic acid is about 12-27%) and antioxidant, skin-protectant vitamin E

Also-called: Meadowfoam Oil | What-it-does: emollient

The emollient plant oil coming from the seeds of the white flowering plant called meadowfoam.  Meadowfoam Oil has a unique fatty acid composition with 95% of it being long chain fatty acids (eicosenoic acid C20:1 - 61%, docosenoic acid C22:1 - 16% and docosadienoic acid C22:2 - 18%) that make the oil extraordinarily stable. It also contains antioxidant components such as vitamin E as well as phytosterols.

Apart from Meadowfoam Oil's crazy stability, the oil is described as non-greasy, rapidly absorbed and having a similar skin feel to more often used jojoba oil. The oil is ideal for products where a soft, smooth, silky feel is required whether it be on skin or hair.

What-it-does: emollient

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.

Squalane - goodie
What-it-does: skin-identical ingredient, emollient | Irritancy: 0 | Comedogenicity: 1

It seems to us that squalane is in fashion and there is a reason for it. Chemically speaking, it is a saturated  (no double bonds) hydrocarbon (a molecule consisting only of carbon and hydrogen), meaning that it's a nice and stable oily liquid with a long shelf life. 

It occurs naturally in certain fish and plant oils (e.g. olive), and in the sebum (the oily stuff our skin produces) of the human skin. As f.c. puts it in his awesome blog post, squalane's main things are "emolliency, surface occlusion, and TEWL prevention all with extreme cosmetic elegance". In other words, it's a superb moisturizer that makes your skin nice and smooth, without being heavy or greasy.

Another advantage of squalane is that it is pretty much compatible with all skin types and skin conditions. It is excellent for acne-prone skin and safe to use even if you have fungi-related skin issues, like seborrhea or fungal acne.

The unsaturated (with double bonds) and hence less stable version of Squalane is Squalene, you can read about it here >>

What-it-does: emollient

A colorless to light yellow oily fluid that works as an emollient (makes your skin nice and smooth) and a solvent for poorly soluble materials, such as sunscreen agents. It also has a light touch, low odor, and good spreadability. It is derived from the amino acid sarcosine and is biodegradable.

Also-called: Borage Seed Oil, Starflower Seed Oil | What-it-does: soothing, emollient

We feel that this one is a bit under the radar probably because the Borage plant is not very well known. Maybe because its name isn't as cool as some others, it's hard to compete with kukui or baobab, not to mention murumuru. But let us tell you when it comes to skin care, borage seed oil is one of the best oils that can happen to your skin. Especially, if it's dry, sensitive, easily irritated, often itchy or eczema prone. 

So what is so special about it? It is the richest known plant source of the super important essential fatty acid, gamma-linolenic acid (GLA). GLA is soothing and nourishing, and can repair even severely dry and irritated skin, but it's pretty rare and borage contains by far the most of it (17-28%). Next to GLA, it also contains more common fatty acids, like linoleic (36%), oleic (18%) or palmitic acid (10%).

If your skin is dry and sensitive, this one is totally for you. 

What-it-does: emollient

A yellowish oily liquid that works as a medium spreading emollient and is suitable for a wide pH range. 

We don't have description for this ingredient yet.

Also-called: Passion Fruit Oil | What-it-does: emollient

The emollient plant oil coming from the passion fruit. It is a high-linoleic acid oil (about 70% LA and 15% oleic acid), that makes your skin feel nice and smooth and supports a healthy skin barrier. As a high-LA oil, it is suitable for all skin types including acne-prone.

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

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

Also-called: Tetrahydrocurcuminoids, Curcumin | What-it-does: antioxidant, skin brightening, soothing

A standardized powdered extract from the roots of the Curcuma longa (Turmeric) plant (together with this and this).  The trio is called Tetrahydrocurcuminoids (THC) and has skin-brightening, anti-inflammatory and antioxidant magic properties. 

Other turmeric extracts have brilliant yellow color that makes them difficult to use but this one is color-free. 

What-it-does: emollient

We don't have description for this ingredient yet.

What-it-does: soothing, emollient

When it comes to sunflower and skincare, the seed oil is the common and well-known one. But according to manufacturer info, the seed extract also contains a bunch of skin goodies, including anti-inflammatory minerals, moisturizing and soothing amino acids, sugars and proteins as well as antioxidant polyphenol derivatives. 

What-it-does: emollient

We don't have description for this ingredient yet.

Also-called: Rosemary Leaf Extract | What-it-does: antioxidant, soothing, antimicrobial/antibacterial

The extract coming from the lovely herb, rosemary. It contains lots of chemicals, including flavonoids, phenolic acids, and diterpenes. Its main active is rosmarinic acid, a potent antioxidant, and anti-inflammatory. It has also anti-bacterial, astringent and toning properties. 

The leaves contain a small amount of essential oil (1-2%) with fragrant components, so if you are allergic to fragrance, it might be better to avoid it. 

Tocopherol - goodie
Also-called: Vitamin E | What-it-does: antioxidant | Irritancy: 0-3 | Comedogenicity: 0-3
  • 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

Bisabolol - goodie
Also-called: Alpha-Bisabolol | What-it-does: soothing

It's one of the active parts of Chamomile that contains about 30% of bisabolol. It's a clear oily fluid that is used in skincare as a nice anti-inflammatory and soothing ingredient. 

What-it-does: emollient

A pseudo-ceramide that is similar to Ceramide 2 in structure and activity and is claimed to be a great ingredient for a healthy skin barrier or to repair damaged skin or hair. In general, Ceramides are super important lipids in the outer layer of the skin and we have written some more about them here >> 

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).

Also-called: Tetrahydrocurcuminoids, Curcumin | What-it-does: antioxidant, skin brightening, soothing

Comes from the well-known Indian spice, turmeric and is part of a trio called Tetrahydrocurcuminoids (THC). You can read more about THC's good properties here

Also-called: Tetrahydrocurcuminoids, Curcumin | What-it-does: antioxidant, skin brightening, soothing

It's one of those ingredients that defies the *BS* theory that if you cannot pronounce it, it must be an evil synthetic and you should not put it on your face.

It comes from the well-known Indian spice, turmeric and is part of a trio called Tetrahydrocurcuminoids (THC). You can read more about THC's good properties here

Also-called: Eucalyptus Essential 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. 

Linalool - icky
What-it-does: perfuming, deodorant

Linalool is a super common fragrance ingredient. It’s kind of everywhere - both in plants and in cosmetic products. It’s part of 200 natural oils including lavender, ylang-ylang, bergamot, jasmine, geranium and it can be found in 90-95% of prestige perfumes on the market. 

The problem with linalool is, that just like limonene it oxidises on air exposure and becomes allergenic. That’s why a product containing linalool that has been opened for several months is more likely to be allergenic than a fresh one.

A study made in the UK with 483 people tested the allergic reaction to 3% oxidised linalool and 2.3% had positive test results. 

Limonene - icky
What-it-does: perfuming, solvent, deodorant

A super common and cheap fragrance ingredient. It's in many plants, e.g. rosemary, eucalyptus, lavender, lemongrass, peppermint and it's the main component (about 50-90%) of the peel oil of citrus fruits.

It does smell nice but the problem is that it oxidizes on air exposure and the resulting stuff is not good for the skin. Oxidized limonene can cause allergic contact dermatitis and counts as a frequent skin sensitizer

Limonene's nr1 function is definitely being a fragrance component, but there are several studies showing that it's also a penetration enhancer, mainly for oil-loving components.

All in all, limonene has some pros and cons, but - especially if your skin is sensitive - the cons probably outweigh the pros.
