Sylveco Smoothing SerumIngredients explained
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.
The emollient plant oil that comes from almonds. Similar to other plant oils, it is loaded with skin-nourishing fatty acids (oleic acid - 55-86% and linoleic acid 7-35%) and contains several other skin goodies such as antioxidant vitamin E and vitamin B versions.
It's a nice, basic oil that is often used due to its great smoothing, softening and moisturizing properties. It's also particularly good at treating dry brittle nails (source).
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.
A super common emollient that makes your skin feel nice and smooth. It comes from coconut oil and glycerin, it’s light-textured, clear, odorless and non-greasy. It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type and easy to formulate with. No wonder it’s popular.
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 >>
A clear, colorless to slightly yellowish oil that makes the skin nice and smooth (emollient), spreads easily on the skin and is marketed as a good alternative to volatile (does not absorb into the skin but rather evaporates from it) silicones like Cyclomethicone.
At first glance, you could think that Bakuchiol is your average plant extract. It is derived from the seeds of Psoralea Corylifolia, aka Babchi, a plant important in Indian and Chinese medicine. The molecule was first isolated in 1973 and several anti-something properties are known about it: it has anti-inflammatory, antioxidant, anti-tumor, anti-bacterial and hepatoprotective magical abilities like plenty of other Ayurvedic plant extracts.
What makes Bakuchiol a special snowflake is the recent discovery that it behaves on the skin in a way very similar to well-known skincare superstar, retinol. While chemically, it has nothing to do with the vitamin-A family, aka retinoids, comparative gene expression profiling (a fancy way of saying that they compared how retinol and bakuchiol modify the way skin cells behave and produce important skin proteins such as collagen) shows that retinol and bakuchiol regulate skin cell behavior in a similar way.
To be more specific, both Bakuchiol and retinol upregulate collagen I, III and IV production and downregulate MMP, the evil collagen attacking enzyme in our skin. This means more collagen stays in our skin and we all know that more collagen equals firmer, more wrinkle-free skin. A 12-week clinical study using a 0.5% Bakuchiol formula with 17 people using it twice a day confirmed a significant improvement in lines and wrinkles, elasticity, firmness and an overall reduction in photo-damage. Also, the test formula was very well tolerated, without any retinol-like side effects.
What's more, a 2018 double-blind study with 44 people compared 0.5% Bakuchiol with 0.5% retinol cream and found that "bakuchiol is comparable to retinol in its ability to improve photoaging and is better tolerated than retinol". A super promising result after 12 weeks.
If you are not a daredevil-type who doesn't want to stop using a super well-proven retinol for a newbie like Bakuchiol, we have good news. The two also work very nicely together and Bakuchiol can actually help to stabilize the otherwise unstable and hard to formulate retinol.
And we are still not done, as Bakuchiol shows not only anti-aging properties but also nice anti-acne effects. 1% Bakuchiol seems to be very effective in itself (57% reduction in acne after 6 weeks treatment) and even better when combined with 2% salicylic acid (67% reduction in acne after 6 weeks). We like that Bakuchiol is such a good team player! The molecule works against acne in multiple ways: It downregulates 5α-reductase (a sebum-controlling enzyme), it is antibacterial (including P. acnes), anti-inflammatory and it inhibits lipid-peroxidation, an evil oxidative process that is recently thought to be a very early trigger in the acne process.
We feel that this description is becoming very long so we will just mention that Bakuchiol also seems to positively regulate hydration-related genes such as Aquaporin 3 and also shows some melanin-inhibiting properties.
Overall, we think Bakuchiol is an awesome molecule with lots of promise both for anti-aging and anti-acne. But the proof compared to the well-established superstars is far from solid, so in a skincare routine, we would rather add Bakuchiol next to retinol than straight up replace it. Unless you are a gimme-the-newest-shiny-thing-under-the-sun-type.
A naturally derived (Ecocert approved) colorless to yellowish oily liquid that's touted as a natural silicone alternative. It's claimed to have great sensorial properties: light but caring, velvety, silky and non-sticky.
It's also great at dissolving UV-filters in sunscreens or dispersing pigments in makeup products. You can also bump into Isoamyl Laurate in hair care products as a hair conditioner that makes combing easier without build up.
A natural emollient ester derived from sugar beets and coconut oil. It's a very light liquid that absorbs quickly into the skin and has a non-oily skin feel.
The manufacturer says it's produced in an innovative, eco-friendly way that saves about 60% on energy consumption and CO2 emission compared to traditional manufacturing methods.
The oil coming from the seeds of the nice, little, yellow-flowered plant called Evening Primrose. Similar to other plant oils, it's loaded with nourishing and moisturizing fatty acids. It's a very rich source of linoleic acid (66-76%), and also contains the soothing and healing superstar fatty acid, gamma-linolenic acid (aka GLA, 7-12%) (Btw, the richest known source of GLA is the borage oil, but evening primrose still counts as a very good source of it). It also contains oleic acid, but not too much around 6-15%.
Since the 1980's, EPO is a well-known food supplement and there are quite a lot of studies examining what happens if you take it orally. It seems to be helpful with a bunch of things: atopic dermatitis, dry eyes, brittle nails, sunburn and even acne.
As for the skin, it's a great hydrating plant oil, that can also reduce inflammation and irritation. It's a superb healing agent that can truly help dry skin, not just on the surface by covering it (and not letting water to evaporate) but by initiating structural changes within the skin. If that's not enough, it also helps skin cell regeneration.
All in all, a real goodie especially for dry, easily irritated skin.
We don't have description for this ingredient yet.
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.
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.
