Ingredients Explained

Skin Conditioning, Solvent

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!

Humectant, Skin Conditioning, Skin Protecting

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Ethoxydiglycol is a synthetic solvent.

Solvents are used to keep ingredients together in a product. They can help dissolve ingredients to stable bases or help evenly distribute ingredients throughout the product.

Ethoxydiglycol also helps deliver other key ingredients into the skin.

Skin Conditioning

This synthetic peptide is created from lysine, valine, and palmitic acid.

According to the manufacturer, in-vitro studies show tissue growth and collagen synthesis. Another in-vivo study found 60 volunteers saw a significant reduction in wrinkles after 84 days.

Due to its palmitic acid base, this peptide may not be fungal-acne safe.

We don't have a description for Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate yet.

This ingredient is a synthetic lipopeptide that is often paired with its sibling, Palmitoyl Dipeptide-5 Diaminohydroxybutyrate, in a trade blend called Syn-Tacks.

The combination of the two peptides target the dermal-epidermal junction (DEJ), or the mesh that connects your epidermis to your dermis. Your DEJ naturally thins with age and exposure.

Despite the "dipeptide" in the INCI name, it's actually a tetrapeptide hooked to a palmitic acid tail. This helps it slip past the skin barrier and stay stable in formula.

According to manufacturer in vitro and in vivo data, the Syn-Tacks blend stimulates key DEJ proteins including Laminin-5, Collagens IV, VII, and XVII, and Integrin β4. Improvements in firmness, elasticity, and suppleness were after about two months of use.

This ingredient is a synthetic lipopeptide and is technically a tripeptide. It's made by connecting palmitic acid to a short amino acid chain so it can move through the skin's fatty outer layers more easily.

It is most often found in formulations with its sibling, Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine in a trade blend called Syn-Tacks.

The combination of the two peptides target the dermal-epidermal junction (DEJ), or the mesh that connects your epidermis to your dermis. Your DEJ naturally thins with age and exposure.

Peer-reviewed research on DEJ targeted peptides and manufacturer data suggests the pair tells your skin cells to produce more structural proteins that hold the DEJ together.

In studies, this translates to firmer skin and a bump in skin thickness via ultrasound.

Magnesium chloride is a mineral salt made from magnesium and chloride. It is mainly used to control product stability and texture in cosmetics.

This ingredient can also play a role in soothing the skin and supporting normal skin function.

Magnesium chloride is water-soluble, generally well tolerated, and does not act as a strong “active” ingredient on its own.

Emulsifying

Polysorbate 20 is a gentle, water-soluble emulsifier and mild surfactant. It stops oil and water from separating to keep your formulas blended and stable.

It also acts as a mild penetration enhancer by helping active ingredients absorb slightly better.

The common safety discussion around this ingredient involves a manufacturing byproduct called 1,4-dioxane.

Trace amounts can form during production but the EU's Scientific Committee on Consumer Safety has concluded that levels at/below 10 ppm in finished products are safe (commercial products consistently fall within acceptable margins).

True allergic reactions are uncommon and the CIR Expert Panel has confirmed this ingredient to be safe as used in cosmetics.

Because it is derived from lauric acid, it may not be fungal acne safe.

Perfuming, Preservative, Solvent

Benzyl Alcohol is most commonly used as a preservative. It also has a subtle, sweet smell. Small amounts of Benzyl Alcohol is not irritating and safe to use in skincare products. Most Benzyl Alcohol is derived from fruits such as apricots.

Benzyl Alcohol has both antibacterial and antioxidant properties. These properties help lengthen the shelf life of products. Benzyl Alcohol is a solvent and helps dissolve other ingredients. It can also improve the texture and spreadability.

Alcohol comes in many different forms. Different types of alcohol will have different effects on skin. This ingredient is an astringent alcohol.

Using high concentrations of these alcohols are drying on the skin. They may strip away your skin's natural oils and even damage your skin barrier. Astringent alcohols may also irritate skin.

Other types of astringent alcohols include:

According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.

Any type of sanitizing product will have high amounts of alcohol to help kill bacteria and viruses.

Preservative

MI is a preservative and known skin irritant. In the past, MI was used for its ability to prevent bacteria, yeast, and fungi growth in low doses.

Nowadays, you'll most likely see MI combined with Methylchloroisothiazolinone (MCI).

Since then, numerous studies have shown this ingredient to cause contact dermatitis, or skin irritation.

The use of this ingredient varies around the world:
