Bskincare Face OilIngredients explained
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.
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.
The oil coming from the seeds of the wild rose bush most common in the southern Andes in Chile (btw, Rosa Rubiginosa, Rosa Eglanteria and Rosa Mosqueta all refer to the same oil, however, the more commonly used Rosa Canina is a bit different). Similar to many other great plant oils, it is a nice nourishing and moisturizing oil loaded with fatty acids (linoleic acid - 44%, linolenic acid - 34% and oleic acid - 14%).
What makes rosehip oil a special snowflake among all the plant oils out there is that it also contains the miracle active, trans-retinoic acid, aka tretinoin. It is the main bioactive component of the oil and has all kinds of magic abilities including restoring and regenerating tissues (the oil is great for scars and burns), decreasing wrinkles, helping acne and even normalizing pore size.
Just one more note: a study found that the tretinoin content of rosehip seed oil greatly depends on the extraction method. The oil coming from cold pressing contained seven times more tretinoin (0.357 ml/l) than the oil from organic solvent extraction. Always go for the cold-pressed version!
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.
The fragrant essential oil coming from the whole plant of Rose Geranium. It has a lovely scent with a mix of rose and citrus.
Like most essential oils, it contains antioxidant and antimicrobial components, but the main ones are fragrant constituents (like geraniol and citronellol). Be careful with it, if your skin is sensitive.
The essential oil coming from the fruit (probably the rind) of the bergamot orange. It's a common top note in perfumes and contains (among others) fragrant compounds limonene (37%), linalyl acetate (30%) and linalool (8.8%).
A well-known issue with bergamot oil (apart from the fragrance allergens) is that it contains phototoxic compounds called furanocoumarins, but more and more commonly furanocoumarin-free versions are used in cosmetic products. Still, if you have sensitive skin and prefer fragrance-free products, bergamot oil is not for you.
