BOSCIA Sake Hydrating And Brightening Serum
Ingredients explained

Saccharomyces Ferment Filtrate is the fancy name of a liquidy, almost-water-like stuff that you get by fermenting and filtering yeast. 

According to manufacturer info it’s rich in all kinds of good-for-your-skin things: essential minerals, amino acids, beta-glucan and vitamins. It’s definitely great for skin moisturization and soothing, and might have some skin brightening and wrinkle repair magic activity as well. 

What-it-does: moisturizer/humectant

A corn sugar derived, water-soluble, pale yellow syrup, that nicely moisturizes the skin. It has a light and smooth skin feel, it is non-tacky, and it can improve the after-feel of the formula. It is also mild and gentle, popular in sensitive skin formulas.

A multi-functional, silky feeling helper ingredient that can do quite many things. It's used as an emulsion stabilizer, solvent and a broad spectrum antimicrobial. According to manufacturer info, it's also a moisturizer and helps to make the product feel great on the skin. It works synergistically with preservatives and helps to improve water-resistance of sunscreens. 

What-it-does: solvent

A clear, colorless liquid that works as a solvent and viscosity decreasing ingredient. It also has great skin-moisturizing abilities. 

A helper ingredient that usually comes to the formula coupled with PEG-40 Hydrogenated Castor Oil. The two together work as surfactants and oil solubilizers. It's a non-sticky duo that works at low concentration and is often used to solubilize fragrance components into water-based formulas.

What-it-does: soothing, preservative

Lactobacillus ferment is an interesting probiotic ingredient with some promising properties. 

First, according to a 2009 Estee Lauder patent, it’s a DNA repair enzyme and it can help to protect the skin against environmental aggressors.

Glycerin - superstar
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • A super common, safe, effective and cheap molecule used for more than 50 years
  • Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
  • Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
  • High-glycerin moisturizers are awesome for treating severely dry skin

Also-called: Aqua;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. 

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.

Caffeine - goodie
What-it-does: antioxidant, perfuming

Hello, our favorite molecule that helps us wake up in the morning and then keeps us going through the day. As a super well-known stimulant from coffee, tea and plenty of other soft drinks, Caffeine needs no introduction. So we will skip right to the part where we talk about what the hell it does in so-so many cosmetic products.

Looking at the research, we were surprised to find how versatile Caffeine is. It is a small, water-loving molecule with pretty good skin penetration abilties. Once in the skin, it has nice antioxidant properties, meaning that it reduces the formation of evil free radicals and it might even be useful in preventing UV-induced skin cancers. 

A menthol-derived cooling agent that is claimed to give a long-lasting cooling effect (similar to menthol itself) while also being moisturizing and less irritating than menthol thanks to the lactic acid part. It's recommended to be used at 0.5-1%.  

Also-called: Pomegranate Enzyme | What-it-does: exfoliant

It's the fancy name for pomegranate enzyme that's obtained by fermenting the pomegranate fruit with Lactobacil­lus lactis. The fermentation process makes the desired phytochemicals readily available and selective filtration techniques are used to isolate the  proteolytic frac­tions.

The end result is the enzyme that increases cell renewal and can be an alternative to acid exfoliation (though it is not as effective as glycolic acid even according to the manufacturer's measurements not to speak about the other benefits of glycolic acid). 

We don't have description for this ingredient yet.

It's the chemically chopped up version of corn starch. According to manufacturer info it helps to keep formulas together (binding), and improves foam quality (makes nice, creamy foam :)). It's also a blend of poly- and monosaccharides and works as a skin moisturizer giving products a nice soft feel.

Also-called: Beet Root Extract | What-it-does: antioxidant, moisturizer/humectant

Beetroot is a beautifully colored vegetable that you probably know from the kitchen. As for skincare - according to manufacturer info - it works as a natural moisturizer that might be able to increase the concentration of NMFs (natural moisturizing factors) in the upper layer of the skin giving skin both immediate and longer term hydration. 

According to Paula's Choice, it's also a colorant and a source of antioxidants

It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol

The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.

What-it-does: solvent

A really multi-functional helper ingredient that can do several things in a skincare product: it can bring a soft and pleasant feel to the formula, it can act as a humectant and emollient, it can be a solvent for some other ingredients (for example it can help to stabilize perfumes in watery products) and it can also help to disperse pigments more evenly in makeup products. And that is still not all: it can also boost the antimicrobial activity of preservatives

What-it-does: chelating, buffering

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). 

What-it-does: moisturizer/humectant, solvent | Irritancy: 0 | Comedogenicity: 1

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.

Also-called: Licorice | What-it-does: soothing, moisturizer/humectant

The salt form of one of the main anti-inflammatory ingredients in the licorice plant, monoammonium glycyrrhizinate. It’s a yellowish powder with a nice sweet smell. 

It’s used mainly for its soothing and anti-inflammatory properties, but according to manufacturer info, it’s also sebum regulating so it's a perfect ingredient for problem skin products. 

Allantoin - goodie
What-it-does: soothing | Irritancy: 0 | Comedogenicity: 0

Super common soothing ingredient. It can be found naturally in the roots & leaves of the comfrey plant, but more often than not what's in the cosmetic products is produced synthetically. 

It's not only soothing but it' also skin-softening and protecting and can promote wound healing.

Also-called: EDDS | What-it-does: chelating

A helper ingredient that helps to neutralize the metal ions in the formula (they usually come from water) so it stays nice longer. The special property of this particular ingredient is that it's more effective against more problematic ions, like Cu (copper) and Fe (iron) compared to less problematic ones like Ca (calcium)  and Mg (magnesium).

Also-called: lye | What-it-does: buffering

The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right. 

For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.  

Lactic Acid - superstar
  • It’s the second most researched AHA after glycolic acid
  • It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
  • It also has amazing skin hydrating properties
  • In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles
  • Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
  • Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)

What-it-does: abrasive/scrub, emollient

We don't have description for this ingredient yet.

Also-called: Fermented Radish Root | What-it-does: antimicrobial/antibacterial, preservative

It's an alternative, natural preservative that comes from radishes fermented with Leuconostoc kimchii, a lactic acid bacteria that has been used to make traditional Korean dish, kimchi. During the fermentation process, a peptide is secreted from the bacteria that has significant antimicrobial properties

It is one of the more promising natural preservatives that can be used even alone (recommended at 2-4%), but it's not as effective as more common alternatives, like parabens or phenoxyethanol

It's a little helper ingredient coming from corn, rice or potato starch that can help to keep skin mat (absorbent), to stabilise emulsions, and to keep the product together (binding). 

We don't have description for this ingredient yet.

Also-called: Damask Rose Flower Oil | What-it-does: antioxidant, perfuming, antimicrobial/antibacterial

We are big fans of all kinds of roses as ornamental plants but when it comes to skincare, it is a mixed bag. Before we list out the good and the not so good, here is an interesting thing. 

The oil content in rose is very, very low so distilling rose essential oil requires huge amounts of rose flowers. It has such a wonderful scent that there are no comparable synthetic alternatives. You can probably guess that this means rose essential oil is expensive.... very very expensive

Also-called: Rosemary Leaf Oil | What-it-does: antioxidant, antimicrobial/antibacterial

The essential oil coming from the leafs of the lovely herb, rosemary. It contains several fragrant components, including the well-known irritant, camphor (around 15%). It has a nice smell, is a potent antioxidant and it's also an antimicrobial agent.

If your skin is sensitive, it's probably a good idea to avoid it.

A spray-dried or freeze-dried version of Aloe Leaf Juice. The point of both drying methods is to make water evaporate from the juice and leave just the "useful" components behind.

So the aloe powder has similar soothing, emollient and moisturizing properties as the juice. You can read a bit more about the juice here. 

What-it-does: preservative

Though the official function of P-Anisic Acid is masking (meaning that it helps to mask not so nice smells in the product), according to manufacturer info it is rather used as a preservative. It is a skin friendly organic acid that works against fungi
