Plix Dewy Serum
Ingredients explained

Also-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. 

Also-called: Zemea | What-it-does: solvent, moisturizer/humectant

Propanediol is a natural alternative for the often used and often bad-mouthed propylene glycol. It's produced sustainably from corn sugar and it's Ecocert approved. 

It's quite a multi-tasker: can be used to improve skin moisturization, as a solvent, to boost preservative efficacy or to influence the sensory properties of the end formula. 

What-it-does: skin brightening, soothing

We don't have description for this ingredient yet.

Alpha-Arbutin - goodie
What-it-does: antioxidant, skin brightening

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).  

Also-called: Pineapple Fruit Extract | What-it-does: soothing, moisturizer/humectant

A goodie fruit extract coming from the lovely pineapple. It contains a bunch of good-for-the-skin stuff:  bromelain and fruit acids  have mild exfoliant properties, and fruit sugars and amino acids give the pineapple fruit nice moisturizing and soothing properties. 

There is also a pineapple extract called pineapple ceramide on the market that's claimed to be loaded with a glucose linked ceramide derivative called glucoceramide. According to the manufacturer, glucoceramide is not only a skin moisturizer but it also helps to lighten the skin and make it more smooth.

A big sugar molecule (polysaccharide) that is used as a natural thickening and gelling agent. It is similar to more commonly used Xanthan Gum, and the two are also often combined to create gel formulas or to stabilize emulsions. 

Also-called: Radianskin | What-it-does: skin brightening

skin-brightening, spot fading active ingredient that goes by the trade name Radianskin. The in-vitro (made in the lab) test results of the manufacturer show that it can prevent melanin formation more effectively than other well-known skin-lightening agents, like ascorbyl glucoside, kojic acid, or arbutin and it has equivalent efficacy to skin-lightening gold-standard ingredient hydroquinone but without cytotoxicity.

There is also a L'Oreal sponsored research showing that the combination of hydroxyphenoxy propionic acid, ellagic acid, yeast extract, and salicylic acid produced comparable skin-lightening results as the standard prescription combination of 4% hydroquinone cream and 0.025% tretinoin cream after 12 weeks. 

Mandelic Acid - goodie
  • Mandelic acid is an AHA that comes from bitter almond
  • It can gently lift off dead surface skin cells and make the skin more smooth and even
  • It has antibacterial properties
  • It’s promising against acne and post inflammatory hyperpigmentation
  • It’s light sensitive, so choose a product with opaque packaging

What-it-does: viscosity controlling

We don't have description for this ingredient yet.

What-it-does: moisturizer/humectant

A 100% natural and plant-derived moisturizer that mimics the natural carbohydrate fraction found in the upper layer of the skin. Its special magic power is to bind to the skin stronger and longer than other moisturizer ingredients do so it can keep the skin hydrated longer than usual.

What-it-does: buffering

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. 

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: preservative

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. 

What-it-does: preservative, deodorant

If you have spotted ethylhexylglycerin on the ingredient list, most probably you will see there also the current IT-preservative, phenoxyethanol. They are good friends because ethylhexylglycerin can boost the effectiveness of phenoxyethanol (and other preservatives) and as an added bonus it feels nice on the skin too.

Also, it's an effective deodorant and a medium spreading emollient

What-it-does: chelating

Super common little helper ingredient that helps products to remain nice and stable for a longer time. It does so by neutralizing the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.

It is typically used in tiny amounts, around 0.1% or less.

What-it-does: buffering | Irritancy: 0 | Comedogenicity: 2

It’s a little helper ingredient that helps to set the pH of a cosmetic formulation to be just right. It’s very alkaline (you know the opposite of being very acidic): a 1% solution has a pH of around 10.

It does not have the very best safety reputation but in general, you do not have to worry about it. 

Also-called: Tartrazine, Yellow 5 | What-it-does: colorant

Ci 19140  or Tartrazine is a super common colorant in skincare, makeup, medicine & food. It’s a synthetic lemon yellow that's used alone or mixed with other colors for special shades. 

FDA says it's possible, but rare, to have an allergic-type reaction to a color additive. As an example, it mentions that Ci 19140 may cause itching and hives in some people but the colorant is always labeled so that you can avoid it if you are sensitive.
