Collagen Serum
Skin Actives

Collagen Serum

A serum to promote and support the synthesis of collagen with added antioxidant activity.
Also-called: Aqua | 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. 

Also-called: Fermented Sea Kelp | What-it-does: moisturizer/humectant, emollient

A viscous yellow to amber colored liquid that's coming from the fermentation of Sea Kelp using lactobacillus. The idea behind the fermentation is that it breaks down the cell walls of the kelp so that the useful stuff inside the cells become bio-available for the skin.

Sea Kelp Ferment is claimed to be an excellent oil-free moisturizer, emollient, and film former. Might also have some skin soothing properties.

Glycerol - goodie
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • Super common, used for more than 50 years
  • Not only a simple moisturizer but plays an important role in keeping the stuff between our skin cells healthy
  • High-glycerin moisturizers are awesome for treating severely dry skin

Sodium Pca - goodie

PCA stands for Pyrrolidone Carboxylic Acid and though it might not sound like it, it is a thing that can be found naturally in our skin. The sodium salt form of PCA is an important skin-identical ingredient and great natural moisturizer that helps the skin to hold onto water and stay nicely hydrated. 

Also-called: Form of Vitamin C, MAP | What-it-does: vitamins, skin brightening

A form of skincare superstar, Vitamin C. If you do not know, what the big deal about Vitamin C is, click here and read all about it, we will wait here for you. 

So now you know that pure vitamin C (aka ascorbic acid, AA) is really unstable and hard to formulate so the cosmetics industry is coming up with a bunch of derivatives to solve the problem and Magnesium Ascorbyl Phosphate (or MAP) is one of them.  

Expand to read more

MAP does solve the stability problem: it's stable up to pH 7, so far so good. What is not so good is that, as the great review study about vitamin C derivatives in the Journal of Cosmetic Dermatology writes, MAP is "at very best, poorly absorbed in comparison to AA." 

Moreover,  derivatives not only have to be absorbed into the skin, they also have to be converted into pure AA. The good news is that in-vitro data shows that MAP does convert, but the bad news is we do not really know if the same is true on real, living human skin. Even if it does, we don't know how good the conversion rate is (but to be fair the same is true for all other derivatives).

Regarding the three magic abilities of pure vitamin C (antioxidant, collagen booster, skin brightener), there is no published data about MAP's antioxidant or photoprotection capabilities. We have better news about the other two things: in-vitro data shows that MAP can boost collagen synthesis similar to AA (though in the case of AA it's proven in-vivo) and even better, MAP is proven to work as a skin brightener in-vivo (on real people). 

Bottom line: when it comes to vitamin C derivatives, MAP is definitely an option. We especially recommend it if you are after skin brightening as this seems to be the strongest point of MAP.

Hyaluronic Acid - goodie
  • It’s naturally in our skin and behaves there like a sponge
  • It can bind up to 1000 times its own weight in water
  • Awesome moisturizer and has other important biological functions
  • Different molecular weight versions exist and that raises questions
  • Skin penetration abilities of high-molecular-weight HA is debated (see geeky details for more info)
  • Usefulness of low-molecular-weight HA is also debated (see geeky details for more info)

Carnosine (L-) - goodie

It's a nature identical, biomimetic peptide that can do multiple good things to the skin:

First, it's an antioxidant that can protect skin from damaging free radicals.

Second, in-vitro (made in the lab, not on real people, so take it with a grain of salt) studies show that it has anti-glycation properties (glycation is the not-so-nice process that happens when we bombard our body with too much sugar that results in damaged body proteins and eventually in more wrinkles).  

Third, also in vitro studies show that carnosine has collagen-boosing magic power.

And last, but not least an in vivo, made on real humans clinical study shows that carnosine is very effective against the damages caused by infrared (IR) radiation. (source)

Also-called: Indian Frankincense Extract | What-it-does: soothing

The extract coming from the Indian Frankincense, a medium sized tree native to India. Mostly the gum-resin is used that is obtained  from the incision made on the trunk of the tree.  It contains about 30-60% resin, 5-10% fragrant essential oil,  and the rest is made up of polysaccharides (mostly arabinose, galactose, xylose).

The biologically most active components of the resin are boswellic acids that have anti-inflammatory propertiesAccording to manufacturer info, the boswellic acids rich resin extract is also a potent inhibitor of elastase (an enzyme that breaks down proteins, including collagen) and has antiGAGase activity (protecting the important natural moisturizing factors, glycosaminoglycans in the skin) meaning that it can help the skin to stay firm for a longer time.

Expand to read more

The reason why we did not award Boswellia Serrata Extract a goodie status is that this INCI name is not clear enough on the type of the extract. It might be a boswellic acids rich, anti-inflammatory extract (that is a goodie) or it might be a fragrant essential oil rich extract used in perfumery or aromatherapy that can be a problem for sensitive skin types. 

Also-called: vitamin B3, nicotinamide | What-it-does: cell-communicating ingredient, vitamins, skin brightening, anti-acne, moisturizer/humectant
  • A multi-functional skincare superstar with several proven benefits for the skin
  • Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration
  • Fades brown spots alone or in combination with amino sugar, acetyl glucosamine
  • Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration
  • Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis
Read all the geeky details about Niacinamide here >>

An amino acid sugar that can be found in the skin and does there good and important things. One of them is that it's a precursor for the biosynthesis of superstar moisturizer, hyaluronic acid. So acetyl glucosamine itself is also an important skin-identical ingredient and natural moisturizing factor.

But that is not all, acetyl glucosamine has two other great properties proved by double-blind clinical trials. First, it's a promising ingredient against wrinkles:  2% can improve wrinkles, particularly in the eye area.

Second, the same amount can also fade - always stubborn - brown spots. (Do not expect magic, though - the photos from the study show the difference after 8 weeks of daily use. The difference is visible, but not that big. It's always good to have realistic expectations. :))  Combined with skincare superstar niacinamide the duo is synergistic and is more effective at improving hyperpigmentation, so if you are after the skin-lightening benefit look out for products that contain both. 

Also-called: Gotu Kola, Tiger Grass | What-it-does: soothing

Centella Asiatica - or gotu kola as normal people call it  - has been used in folk medicine for hundreds of years. It’s traditionally used to improve small wounds, burns and scratches and it’s also a well known anti-inflammatory agent for eczema.

Recently science has taken an interest in gotu kola as well and it turns out it really has many active compounds with interesting benefits. Just for hard-core geeks, active compounds include pentacyclic triterpenoid saponins, asiaticoside and madecassoside, asiatic and madecassic acid.

Expand to read more

The triterpenoid components are interesting because they are shown to be able to stimulate GAGs  (glycosaminoglycans - polysaccharides that are part of the liquidy stuff between our skin cells), and especially hyaluronic acid synthesis in our skin. 

Madecassoside can help in burn wound healing through increasing antioxidant activity and enhancing collagen synthesis. Asiaticoside was shown to increase antioxidant levels on rats skin when applied at 0.2%. 

Centella Asiatica also often shows up in products that try to treat cellulite or striae. Of course it cannot make a miracle but it might have some effect via regulating microcirculation and normalizing the metabolism in the cells of connective tissues. 

Bottom line: Gotu Kola is a great plant ingredient with proven wound healing, anti-inflammatory and antioxidant properties. Be happy if you spot it on the INCI list.

Also-called: EGCG | What-it-does: antioxidant, soothing

If EGCG does not tell you anything, green tea sure does. We have written about green tea in excruciating details, so if you wanna become an expert in the "green tea in skincare" topic,  click here and read it

So now you know that EGCG is the magic ingredient in green tea. It's the most active polyphenol that green tea owes most of its magic properties to. It's a fantastic antioxidant, anti-inflammatory and anticarcinogenic agent. Be happy, if you spot it on the ingredient list.

Citric Acid - goodie
What-it-does: exfoliant, 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. 

Expand to read more

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.

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. 

Expand to read more

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.

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.
