Roushun beauty Vitamin C Serum
Ingredients explainedAlso-called: Water | What-it-does: solvent
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it's the biggest thing out of all the stuff that makes up the product.
It's mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
Butylene glycol, or let's just call it BG, is a multi-tasking colorless, syrupy liquid. It's a great pick for creating a nice feeling product.
BG's main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin.
It's an ingredient whose safety hasn't been questioned so far by anyone (at least not that we know about). BG is approved by Ecocert and is also used enthusiastically in natural products. BTW, it's also a food additive.
We don't have description for this ingredient yet.
It's a nice glycerin-based humectant and emollient that gives skin a smooth and luxurious feel.
Arctostaphylos Uva-Ursi is a little plant with nice red berries that lives in the North and is also called bearberry or kinnikinnick. According to Wikipedia the uva-ursi part means "grape of the bear".
As for skincare bearberry is interesting because it contains the well-known skin lightening agent arbutin. The leaves contain 5-15% percent of it and might be able to help fading brown spots on the skin. Also, kinnikinnick (such a cool name :)) is an antioxidant and has some antibacterial activity.

Also-called: True Ginseng, Ginseng, Korean Ginseng | What-it-does: antioxidant, emollient
Atraditional Korean medicine used for more than 2000 years. Regarding skin care, its main thing seems to be enhancing skin nutrition and metabolism as a result of improvingblood circulation.
It also contains biologically active components referred to as ginseng saponins (ginsenosides) that have potent antioxidant properties.
An optical isomer of naturally occurring arbutin (or beta-arbutin). Just like its sibling, alpha-arbutin is also a skin-brightening, depigmenting agent.
Researching the difference between the two kinds of arbutin, you can read in multiple places on the internet that alpha-arbutin is stronger in effect. Unfortunately, it's never backed up with a credible source. :( Our own research resulted in conflicting results: a study from 1995 found that alpha-arbutin is 10x as effective on mouse melanoma as beta-arbutin. On the other hand, a more recent study from 2015 found that beta-arbutin is more effective both on mouse melanoma cells and on human melanoma cells (btw, kojic acid was the most effective on human melanoma cells).
None of the studies we could find is in-vivo (made on real people) anyways, so who knows. We think you cannot go wrong with trying both beta- and alpha-arbutin and see if one works better for you than the other.
It's pretty much the current IT-preservative. It's safe and gentle, but even more importantly, it's not a feared-by-everyone-mostly-without-scientific-reason paraben.
It's not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.
Other than having a good safety profile and being quite gentle to the skin it has some other advantages too. It can be used in many types of formulations as it has great thermal stability (can be heated up to 85°C) and works on a wide range of pH levels (ph 3-10).
It's often used together with ethylhexylglycerin as it nicely improves the preservative activity of phenoxyethanol.
A mildly viscous, amber-colored liquid with fatty odor, made from Castor Oil and polyethylene glycol (PEG).
If it were a person, we'd say, it's agile, diligent & multifunctional. It's mostly used as an emulsifier and surfactant but most often it is used to solubilize fragrances into water-based formulas.
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

Also-called: Fragrance, Parfum;Parfum/Fragrance | What-it-does: perfuming
Exactly what it sounds: nice smelling stuff put into cosmetic products so that the end product also smells nice. Fragrance in the US and parfum in the EU is a generic term on the ingredient list that is made up of 30 to 50 chemicals on average (but it can have as much as 200 components!).
If you are someone who likes to know what you put on your face then fragrance is not your best friend - there's no way to know what's really in it.
Also, if your skin is sensitive, fragrance is again not your best friend. It's the number one cause of contact allergy to cosmetics. It's definitely a smart thing to avoid with sensitive skin (and fragrance of any type - natural is just as allergic as synthetic, if not worse!).
Citric acid comes from citrus fruits and is an AHA. If these magic three letters don't tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA.
So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.
There is also some research showing that citric acid with regular use (think three months and 20% concentration) can help sun-damaged skin, increase skin thickness and some nice hydrating things called glycosaminoglycans in the skin.
But according to a comparative study done in 1995, citric acid has less skin improving magic properties than glycolic or lactic acid. Probably that's why citric acid is usually not used as an exfoliant but more as a helper ingredient in small amounts to adjust the pH of a formulation.

It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like. Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-called rheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range.
Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It's approved by Ecocert and also used in the food industry (E415).
A little helper ingredient that is used to adjust the pH of the product. It also helps to keep products stay nice longer by neutralizing the metal ions in the formula (they usually come from water).
