NCN PRO SKINCARE

All-Trans Retinol With Non-Prescription Tretinoin

Active Ingredients: Retinol 2% (Water, Phospholipids, Retinol), Non-Prescription Tretinoin (0.018%), Trylagen (5%).
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. 

What-it-does: emollient

A very 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, and it’s also easy to formulate with. No wonder it’s popular. 

Retinol - superstar
Also-called: Vitamin A, Form of Retinoids | What-it-does: cell-communicating ingredient
  • Retinol (pure Vitamin A itself) is probably the most proven anti-aging ingredient available OTC
  • Retinol is not itself active, it has to be converted in the skin to retinoic acid to actually do something
  • Once converted it theoretically has the same effect as all-trans-retinoic acid, aka tretinoin
  • A generally accepted ballpark number is that retinol is 10 times less potent than retinoic acid
  • It makes skin less wrinkled, smoother, firmer and tighter
  • It might also be helpful for acne prone skin as it normalizes keratinization and makes the pores produce less sebum
  • Possible side effects and irritation are also much less than with retinoic acid
  • Do not use whilst pregnant

Tretinoin - superstar
Also-called: All-Trans-Retinoic Acid, Form of Retinoids | What-it-does: cell-communicating ingredient
  • Tretinoin (a metabolite of vitamin A) is the gold standard anti-aging ingredient that is also FDA-approved (and it's the only one so far!)
  • It's an all around skin issue fixer as it works at the skin cell level and makes your skin cells behave in a healthy and normal way
  • It makes the skin less wrinkled, firmer, smoother and tighter, everything you could want from an anti-aging ingredient
  • It's also an effective acne treatment. It normalizes keratinization and makes the pores produce less sebum
  • It's also a skin lightener though not as effective as gold-standard hydroquinone.
  • Side effects with tretinoin are very common. Irritation, skin flaking, redness, and drier skin are usual
  • Do not use tretinoin (or any form of retinoids) while pregnant
  • To minimize side effects introduce tretinoin slowly into your routine (see more how to use tips in geeky details)

This ingredient name is not according to the INCI-standard. :( What, why?!

A trade name that refers to the following correct INCI listing:
Water, Pseudoalteromonas Ferment Extract, Hydrolyzed Soy Protein, Hydrolyzed Wheat Protein, Tripeptide-10 Citrulline, Tripeptide-1, Lecithin, Xanthan Gum, Carbomer, Triethanolamine, Caprylyl Glycol

It's claimed to be an anti-aging "complex" that acts on all stages of the collagen life-cycle: it stimulates collagen production, controls the dimensions of the fibers and inhibits the enzymatic degradation of collagen. According to the manufacturer's tests,  wrinkle depth is reduced by 29% in one month.

Grape Seed Oil - goodie
Also-called: Grape Seed Oil | What-it-does: antioxidant, emollient

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

Avocado Oil - goodie
Also-called: Avocado Oil, Persea Americana Oil | What-it-does: antioxidant, emollient

The oil coming from the pulp of one of the most nutritious fruits in the world, the avocado. It's loaded with nourishing and moisturizing fatty acid, oleic (70%) and also contains some others including palmitic (10%) and linoleic acid (8%). It also contains a bunch of minerals and vitamin A, E and D

Avocado oil has extraordinary skin penetration abilities and can pass and nourish different skin layers. It's a very rich, highly moisturizing emollient oil  that makes the skin smooth and helps with the barrier function. Thanks to its vitamin E content it also has some antioxidant properties. 

Also-called: Sunflower Oil | What-it-does: emollient | Irritancy: 0 | Comedogenicity: 0

Sunflower does not need a big intro as you probably use it in the kitchen as cooking oil, or you munch on the seeds as a healthy snack or you adore its big, beautiful yellow flower during the summer - or you do all of these and probably even more. And by even more  we mean putting it all over your face as sunflower oil is one of the most commonly used plant oils in skincare.

It’s a real oldie: expressed directly from the seeds, the oil is used not for hundreds but thousands of years. According to The National Sunflower Association, there is evidence that both the plant and its oil were used by American Indians in the area of Arizona and New Mexico about 3000 BC. Do the math: it's more than 5000 years – definitely an oldie.

Our intro did get pretty big after all (sorry for that), so let's get to the point finally: sunflower oil - similar to other plant oils - is a great emollient that makes the skin smooth and nice and helps to keep it hydrated. It also protects the surface of the skin and enhances the damaged or irritated skin barrier. Leslie Bauman notes in Cosmetic Dermatology that one application of sunflower oil significantly speeds up the recovery of the skin barrier within an hour and sustains the results 5 hours after using it.

It's also loaded with fatty acids (mostly linoleic (50-74%)  and oleic (14-35%)). The unrefined version (be sure to use that on your skin!) is especially high in linoleic acid that is great even for acne-prone skin. Its comedogen index is 0, meaning that it's pretty much an all skin-type oil

Truth be told, there are many great plant oils and sunflower oil is definitely one of them.

Jojoba Seed Oil - goodie
Also-called: Jojoba Oil | What-it-does: emollient

Jojoba is a drought resistant evergreen shrub native to Southwestern 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 a really special and unique one: technically - or rather chemically - it's not an oil but a wax ester (and calling it an oil is kinda sloppy). 

Expand to read more

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 lots of 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 to 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, and 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.

All in all, 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.

Shea Butter - goodie
Also-called: Shea Butter | What-it-does: skin-identical ingredient, emollient

Unless you live under a rock you must have heard about shea butter. It's probably the most hyped up natural butter in skincare today. It comes from the seeds of African Shea or Karite Trees and used as a magic moisturizer and emollient.

But it's not only a simple emollient, it's considered to be an NMF (Natural Moisturizing Factor) that regenerates and soothes the skin and also protects it from external factors (such as UV rays or wind). If that would not be enough it's also rich in antioxidants (among others vitamin A, E, F, quercetin and epigallocatechin gallate). If you are looking for rich emollient benefits + more, shea is hard to beat. 

Aloe Leaf Juice - goodie
Also-called: Aloe Vera | What-it-does: soothing, moisturizer/humectant

Aloe Vera is one of today’s magic plants. It does have some very nice properties indeed, though famous dermatologist Leslie Baumann warns us in her book that most of the evidence is anecdotal and the plant might be a bit overhyped.

What research does confirm about Aloe is that it’s a great moisturizer and has several anti-inflammatory (among others contains salicylates, polysaccharides, magnesium lactate and C-glucosyl chromone) as well as some antibacterial components. It also helps wound healing and skin regeneration in general. All in all definitely a goodie.

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: emollient, emulsifying, viscosity controlling, surfactant/cleansing | Irritancy: 1 | Comedogenicity: 2

A super common multitasker ingredient that gives your skin a nice soft feel (emollient). It also helps water and oil to blend (emulsifier) and to thicken up products

It’s a so-called fatty alcohol (a mix of cetyl and stearyl alcohol - other two emollient fatty alcohols).  Though alcohol is in its name, its properties are totally different from the properties of “normal” alcohol, or denat. alcohol. It’s not drying and not irritating and totally ok for the skin.

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

Vitamin E - superstar
Also-called: Vitamin E | What-it-does: antioxidant, vitamins | Irritancy: 2 | Comedogenicity: 2
  • 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: Mallow Extract | What-it-does: soothing, emollient, astringent

We don't have description for this ingredient yet.

This ingredient name is not according to the INCI-standard. :( What, why?!

Probably refers to Symphytum Officinale Root Extract.

It's one of the most commonly used thickeners. If the product is too runny, a little of xanthan gum will help make it more gel-like. The slight problem with it though is that too much xanthan gum tends to make the product sticky. 

BTW, it’s natural stuff produced from some sugars called glucose and sucrose. It’s approved by Ecocert and also used in foods (E415). 

What-it-does: emollient, emulsifying

A 100% plant derived, natural (Ecocert approved) multi-functional ingredient that has emollient and moisturizing properties, can work as a co-emulsifier (meaning that next to other emulsifiers it can help water and oil to mix)  and even more importantly has a strong antimicrobial activity

Thanks to this last thing, it allows a lower percentage of traditional preservative or it might even be able to completely replace them.
