The Jojoba Company Ultimate Youth PotionIngredients explained
Jojoba is a drought resistant evergreen shrub native to South-western North America. It's known and grown for jojoba oil, the golden yellow liquid coming from the seeds (about 50% of the weight of the seeds will be oil).
At first glance, it seems like your average emollient plant oil: it looks like an oil and it's nourishing and moisturizing to the skin but if we dig a bit deeper, it turns out that jojoba oil is really special and unique: technically - or rather chemically - it's not an oil but a wax ester (and calling it an oil is kind of sloppy).
So what the heck is a wax ester and why is that important anyway? Well, to understand what a wax ester is, you first have to know that oils are chemically triglycerides: one glycerin + three fatty acids attached to it. The fatty acids attached to the glycerin vary and thus we have many kinds of oils, but they are all triglycerides. Mother Nature created triglycerides to be easily hydrolyzed (be broken down to a glycerin + 3 fatty acid molecules) and oxidized (the fatty acid is broken down into small parts) - this happens basically when we eat fats or oils and our body generates energy from it.
Mother Nature also created wax esters but for a totally different purpose. Chemically, a wax ester is a fatty acid + a fatty alcohol, one long molecule. Wax esters are on the outer surface of several plant leaves to give them environmental protection. 25-30% of human sebum is also wax esters to give us people environmental protection.
So being a wax ester results in a couple of unique properties: First, jojoba oil is extremely stable. Like crazy stable. Even if you heat it to 370 C (698 F) for 96 hours, it does not budge. (Many plant oils tend to go off pretty quickly). If you have some pure jojoba oil at home, you should be fine using it for years.
Second, jojoba oil is the most similar to human sebum (both being wax esters), and the two are completely miscible. Acne.org has this not fully proven theory that thanks to this, jojoba might be able to "trick" the skin into thinking it has already produced enough sebum, so it might have "skin balancing" properties for oily skin.
Third, jojoba oil moisturizes the skin through a unique dual action: on the one hand, it mixes with sebum and forms a thin, non-greasy, semi-occlusive layer; on the other hand, it absorbs into the skin through pores and hair follicles then diffuses into the intercellular spaces of the outer layer of the skin to make it soft and supple.
On balance, the point is this: in contrast to real plant oils, wax esters were designed by Mother Nature to stay on the surface and form a protective, moisturizing barrier and jojoba oil being a wax ester is uniquely excellent at doing that.
Jojoba Oil/Macadamia Seed Oil Esters is the major component of a skin surface lipid mimetic mixture trade named L22.
So what the heck is a skin surface lipid mimetic mixture? Let's start with skin surface lipids (SLSs): these are the oily substances that your skin produces (mainly the sebaceous glands, a smaller part comes from the epidermis) to keep the skin nice and moisturized. The main components are fatty acids (FAs), triglycerides, cholesterol, cholesteryl esters, wax esters, and squalene. This mixture has a super important role in keeping the skin barrier healthy.
So Jojoba Oil/Macadamia Seed Oil Esters is a jojoba and macadamia oil-derived ingredient that contains fatty acids, triglycerides, and wax esters. It comes to the formula with Squalene, Phytosteryl Macadamiate (botanical sourced version of cholesteryl ester) and Phytosterols (botanical version of cholesterol) in the ratios found in young, healthy adult skin.
So the main skill of L22 is barrier repair and skin hydration and the manufacturer did several double-blind, vehicle-controlled studies to show it really works. It compared 3% of L22 with 3% of olive oil or 3% of caprylic/capric triglyceride alone or combined with Ceramide 2 in a vehicle. 60 minutes after the application, barrier recovery was by far the best by the L22 + Ceramide 2 (0.1%) combination, followed by L22 alone, and then by Olive + Ceramide 2 and Olive alone. Skin hydration was measured 4 hours after application and again, the L22 + Ceramide 2 combination performed the best followed by L22 alone.
Another study compared 3% L22 with 3% petrolatum (the gold standard occlusive agent). After 1 hour, they performed similarly both for barrier repair and skin hydration, but after 2 weeks of use and a 1 week regression period, L22 showed significantly better results.
So the bottom line is: if barrier repair is something that you are interested in, the skin surface lipids of L22 can definitely be worth a try. Even better, if the formula also contains Ceramide 2.
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 >>
Thanks to Nivea, Q10 is a pretty well-known ingredient and the fame and Beiersdorf's (the parent company of Nivea) obsession with it are not for no reason. It's an antioxidant found naturally in human cells where it plays a big role in energy production.
In fact, it's so important for energy production that if taken as an oral supplement it has a caffeine-like effect and if taken at night you will probably not sleep very well (so you should take it in the morning). Q10 supplementation is not a bad idea: it not only gives you energy but research also shows that oral Q10 increases the Q10 level of the skin (of course, it decreases with age like pretty much every good thing in the skin) and may help to reduce wrinkles. If you are not for supplements, dietary sources include fish, spinach, and nuts.
As for skincare, Q10 comes in the form of a yellow, oil-soluble powder that's shown to absorb into the upper layer of the skin and act there like an awesome antioxidant. It not only has preventative effects but might also be able to reduce the depth of wrinkles, though 0.3% Q10 was used in the study that counts as really high (products containing that much should be very yellow!).
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.
As for its composition, it's loaded with skin goodies: it's very rich in fatty acids, including oleic (73%), palmitic (15%), and linoleic (9%) acids. It also contains some natural antioxidants, including Vitamin E and the oil shows an outstanding oxidative stability.
If you have dry skin that needs some pampering, Marula oil is a good choice.
A beautiful golden-yellow oil coming from the Camellia tree. It's a 5 -10 meters high tree with spectacular white flowers native to Asia. It's pretty common there and also used as cooking oil or salad dressing. Sometimes Camellia oil is referred to as "the olive oil of Asia".
So what can it do for the skin? Similar to many other great non-fragrant plant oils, it's a great emollient and moisturising oil for dry skin. It's light in texture, absorbs fast into the skin and leaves it soft and supple.
It contains a bunch of good-for-the-skin stuff: it's very rich (70-85%) in nourishing and moisturising fatty acid, oleic acid (though if you are acne-prone be careful with oleic acid), contains significant amount of antioxidant vitamin E (0.15%) as well as great emollient and antioxidant squalene (2-3%).
All in all, a skin goodie especially for dry skin.
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).
As for skincare, argan oil is loaded with lots of skin goodies (but so are many other plant oils): it contains 80% nourishing and moisturizing unsaturated fatty acids, mainly oleic (38-50%), linoleic (28-38%) and palmitic (10-18%). It also contains a relatively large amount of antioxidant vitamin E (600-900 mg/kg, about twice as much as olive), small amounts of antioxidant phenols (including caffeic acid, ferulic acid, and epicatechin), as well as some rare sterols with soothing and anti-inflammatory properties.
Thanks to all the above goodness in argan oil, it can greatly nourish and moisturize the skin and hair. It's also claimed to be able to neutralize collagen-damaging free radicals, help reduce scars, and revitalize and improve skin elasticity. You can even read that argan might help acne-prone skin, but being a high oleic oil, we would be careful with that.
All in all, argan oil is a real goodie but we do not fully understand the special miracle status it enjoys.

Phytosteryl Macadamiate is the combination of phytosterol and fatty acids coming from Macadamia oil. It is a botanical version of cholesteryl esters found in skin surface lipids. It comes to the ingredient list as part of L22, a skin surface lipid mimetic whose main job is barrier repair and skin hydration.
The essential oil coming from the Manuka tree native to New Zealand. It is distantly related to the Australian Tea Tree Oil, although their chemical composition is very different.
The main antibacterial active in tea tree oil is terpinen-4-ol (40%), while manuka's main actives are so-called cyclic triketones, such as Leptospermone, Iso-leptospermone, and Flavesone (20-30%). Both oils are antibacterial and antifungal but in different ways.
While tea tree oil is a pretty well established anti-acne ingredient, manuka has more of a "might be useful" status for problem skin. Its strong suit is treating fungal infections such as athlete's foot, nail bed infections or foot odor. Other than that, manuka can help to relax muscles (useful for treating muscle and joint pain) and also has some antioxidant activity.
