KUDRA Ölmez Çiçek Yenileyici SerumIngredients explained
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 >>
The oil coming from the seeds of dog-rose, a wild rose species native to Europe, northwest Africa and western Asia. It's a nice emollient, moisturizing plant oil loaded with skin-nourishing fatty acids (linoleic acid - 51%, linolenic acid - 19% and oleic acid - 20%).
If you start to dig a bit deeper into the rosehip oil topic, you will soon see that there are lots of species of rose, and it's all a bit confusing to know what the differences and similarities between the oils of the different roses are. As far as our research can tell, here is the gist.
In skincare two major types of rosehip oil are used:
1. Rosa Rubiginosa that is a synonym for Rosa Eglanteria and for Rosa Mosqueta. We will call it RR from now on.
2. Rosa Canina, or RC
The oil content and composition of RR and RC is similar, but there are some differences: RR contains 8% of oil, while RC contains a bit more, 10%. However, the quality of RR oil seems to be a bit better: it contains 78% essential unsaturated fatty acids while RC contains only 71%. Also, the linoleic-oleic ratio of RR is better (3.3 vs 2.5) that might be important if your skin is acne-prone (as linoleic acid is good for acne and oleic is not).
There is one more important thing to mention: RR oil is famous for containing the miracle active, tretinoin. Though Wikipedia puts RR and RC oil under the same article called as Rose hip seed oil, the referenced research about tretinoin content examines only Rosa Rubiginosa. We looked for a research paper explicitly stating that Rosa Canina also contains tretinoin, but could not find one, so we can neither deny nor confirm it. What we could find is a paper mentioning the tocopherols (vitamin E) and carotenoids (pro-vitamin A) content of Rosa Canina oil that gives it some nice antioxidant properties.
All in all, it is a great emollient plant oil with great fatty acids beneficial for any skin type.
The emollient plant oil coming from the seeds of Pomegranate. The red fruit has lots of seeds (100-200 per fruit), but 7 kg of them are needed for 1 kg of oil. Among the many similar plant oils, Pomegranate oil is a really unique one, as its main fatty acid (60%) is a rare one called punic acid, a so-called conjugated fatty acid with three double bonds. It also contains the common linoleic (2-10%) and oleic acids (3-12%), but only in small amounts.
Punic acid is thought to be a biologically active compound, a powerful anti-inflammatory, and antioxidant agent. The oil itself is also claimed to have strong antioxidant properties as well as having excellent nourishing and moisturizing abilities. On top of that, we also found a research that examined Pomegranate as a cosmeceutical source and it concluded that the seed oil can nicely promote the regeneration of the epidermis (the top layer of the skin).
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.
Castor oil is sourced from the castor bean plant native to tropical areas in Eastern Africa and the Mediterranean Basin. It is an age-old ingredient (it’s over 4,000 years old!) with many uses including as a shoe polish, food additive and motor lubricant. You would be reasonable to think that putting shoe polish on your face wouldn’t be the best idea, but it turns out castor oil has some unique properties that make it a stalwart in thick and gloss-giving formulas (think lipsticks and highlighters).
So what is so special about it? The answer is its main fatty acid, called ricinoleic acid (85-95%). Unlike other fatty acids, ricinoleic acid has an extra water-loving part (aka -OH group) on its fatty chain that gives Castor Oil several unique properties. First, it is thicker than other oils, then its solubility is different (e.g. dissolves in alcohol but not in mineral oil), and it allows all kinds of chemical modifications other oils do not, hence the lots of Castor oil-derived ingredients. It is also more glossy than other oils, in fact, it creates the highest gloss of all natural oils when applied to the skin. Other than that, it is a very effective emollient and occlusive that reduces skin moisture loss so it is quite common in smaller amounts in moisturizers.
While it is very unlikely (and this is true for pretty much every ingredient), cases of reactions to castor oil have been reported, so if your skin is sensitive, it never hurts to patch test.
We don't have description for this ingredient yet.
If you are into perfumes, you must know patchouli as an important essential oil in the perfume industry. It boasts a pleasant woody, earthy and camphoraceous scent and has fixative properties (makes the fragrance long-lasting).
Its composition is pretty unique: it does not contain any of the EU's 26 most common fragrance allergens, but its most important components are patchoulol (30%) and alpha-patchoulene (6%) which are responsible for its aroma and antifungal properties.
Among essential oils, the allergen profile of patchouli counts as pretty good (much better than ylang-ylang or lemongrass oils), but if your skin is sensitive, it's still best to avoid it.
The oil coming from the seeds of the carrot, the orange root vegetable we all know and eat regularly. This oil is a really tricky one, as it can refer to two types of oil that can both be extracted from the carrot seeds: the essential oil (about 0.83% yield) and the fixed oil (about 7.84% yield).
The two seed oils are very different and to make matters even worse these two oils are also very different from carrot root oil, or carrot oil, that is basically carrot root extract macerated in a carrier oil such as sunflower or olive oil and is the one that contains the vitamin A precursor, carotene.
Let's start with the fixed oil: it's a nice emollient plant oil that is loaded with moisturizing fatty acids (petroselinic acid - 60% and linoleic acid - 12% are the main ones). Other important components are carotol (30%) and daucol (12%) that give the seed oil antifungal and antioxidant properties. Browsing cosmetic manufacturer info, the oil is also often described as revitalizing, toning and stimulating.
As for the essential oil, it is a light yellow colored oil with a rich, spicy and earthy fragrance. Its main component is carotol (about 65%) but similar to other essential oils, it is a chemically complex mixture with lots of compounds in small amounts. The essential oil also has antifungal and antioxidant properties but also contains fragrant components that might irritate sensitive skin types.
