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.

We don't have a description for Isoleucine.
Proline is an amino-acid. It helps moisturize the skin and plays an important role in creating proteins.
Proline is one of the building blocks for producing collagen. As we age, our bodies produce less collagen. Collagen helps the skin look plump and firm.
In medicine, proline is used as an osmoprotectant. This means it helps prevent oxidative degradation in other drugs.
Our bodies are able to produce proline naturally, but certain conditions may inhibit this production. In that case, proline can be obtained from eating egg whites, soy protein, dairy products, asparagus, mushrooms, and seaweed.
Learn more about ProlineThreonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Threonine is vital for creating collagen and elastin. Collagen and elastin support youthful and firm skin. Our bodies decrease collagen production naturally with age.

Phenylalanine is also used to help even out skin tone due to its ability to disrupt the melanin production process.
Two structures of phenylalanine exist: L-phenylalanine and D-phenylalanine. L-phenylalanine is essential, this means our bodies cannot produce it naturally and we must get it from foods. Our bodies convert D-phenylalanine to neurotransmitters, and D-phenylalanine is found in our bodies naturally.
Some foods that contain L-phenylalanine include eggs, soybeans, beef, milk.
Learn more about PhenylalanineAspartic Acid is an amino acid that our bodies produce naturally. It is an antioxidant.
Our body uses Aspartic Acid to help build collagen and elastin. It also plays a role in hydrating skin.
Antioxidants help mitigate damage from free-radical molecules. These are molecules that originate from external sources such as pollution, cigarette smoke, or the sun.
Learn more about Aspartic AcidPCA is derived from amino acids and is naturally found in our skin's barrier.
As a humectant, PCA helps draw and hold moisture to the skin. Studies show it is effective at helping the skin stay hydrated long-term.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
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.
Read more about some other popular AHA's here:
Learn more about Citric AcidSodium Lactate is the sodium salt of lactic acid, an AHA. It is a humectant and used to adjust the pH of a product.
Sodium Lactate is part of our skin's NMF, or natural moisturizing factor. Our NMF is essential for the hydration of our top skin layers and plasticity of skin.
It also influences our skin's natural acid mantle and pH, which protects our skin from harmful bacteria.
Our NMF is formed from amino acids, lactic acid, sugars, minerals, peptides, and electrolytes. As we age, our NMF naturally depletes. Other sources of NMF depletion include harsh and drying ingredients such as denatured alcohol. Sodium lactate can help replenish our NMF, leading to more hydrated and plump skin.
High percentages of Sodium Lactate can have an exfoliating effect.
Sodium Lactate is produced from fermented sugar.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.
Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
In the US, the alternative name for parfum is 'fragrance'.
The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
