A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

As an emulsifier, it is used to prevent oils and waters from separating. It can also
Manufacturers use the name Olivem 1000. This ingredient has been found to preserve the natural microbiome of skin. Having a healthy microbiome helps keep our skin healthy and protects against harmful bacteria. This ingredient is grouped with Sorbitan Olivate under the name Olivem 1000.
Learn more about Cetearyl OlivateSorbitan Olivate is created from the fatty acids in olive oil and sorbitol.
This ingredient is an oil in water emulsifier. It helps stabilize a product by preventing oils and waters from separating. Sorbitan Olivate also helps hydrate the skin.
Manufacturers sell sorbitan olivate under the name OliveM 1000. OliveM 1000 a multifunctional ingredient. It is self-emulsifying. According to a manufacturer, OliveM 1000 does not disrupt natural skin biome.
Due to its olive oil base, this ingredient may not be fungal-acne safe.
Learn more about Sorbitan OlivateAcetyl Hexapeptide-8 is a peptide. A common name for this peptide is Argireline.
Argireline has a similar function to botox; it prevents muscle movement and contractions slightly. By preventing muscles from moving, argireline also prohibits the formation of fine lines and wrinkles. However, research is lacking in proving this ingredient to be as effective as botox.
On the other hand, argireline tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

This ingredient consists of four amino acids and palmitic acid. These amino acids are arginine, proline, glutamine, and glycine.
This ingredient has many benefits. These benefits include boosting collagen production, fighting inflammation, and reversing UV damage.
By preventing our bodies from producing interleukins, Palmitoyl Tetrapeptide-7 helps fight inflammation. An interleukin is a chemical that signals to the body to produce an inflammatory response. Interleukin production is accelerated by UV radiation.
Palmitoyl Tetrapeptide-7 tells our body to create more collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.

Learn more about Palmitoyl Tetrapeptide-7Palmitoyl Tripeptide-1 is a 3-amino acid peptide. Peptides are building blocks for protein.
This ingredient is a signal peptide, meaning it tells our skin to create collagen. Collagen is a protein that makes connective tissue. Boosting collagen production leads to a healthier skin barrier. Having a healthy skin barrier means having firm and hydrated skin.
Palmitoyl Tripeptide-1 can help reduce wrinkles and make the skin look more youthful.

Learn more about Palmitoyl Tripeptide-1This 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.
Learn more about Palmitoyl Tripeptide-5Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

This ingredient comes from potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.
Both potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.
You'll often find this ingredient used with other preservatives.
Learn more about Potassium SorbateCaprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolSodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.
Its main functions are to maintain the pH of a product and neutralize metal ions.
The acidity of our skin is maintained by our glands and skin biome; normal pH level of skin is slightly acidic (~4.75-5.5).
Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
