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.

This is a lightweight diester (caprylic/capric acid + butylene glycol) with emollient and skin conditioning properties.

According to a manufacturer, this ingredient can help add a "cushiony" oil phase without making it heavy.

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.

Hydrolyzed Keratin is derived from keratin. Keratin is a large protein that is naturally found in our hair and skin.

Studies show keratin is able to seal broken hair cuticles, helping to prevent split ends and breakage.

Menthol is a compound found in mint plants, such as peppermint. In its pure form, it is a clear crystalline substance.

Menthol is known for its cooling sensation; however, the cooling is actually from your skin being sensitized. Menthol can worsen rosacea. We recommend speaking with a professional if you have concerns.

Salicylic Acid (also known as beta hydroxy acid or BHA) is a well-known ingredient for treating skin that struggles with acne and clogged pores. It exfoliates both the skin's surface and deep within the pores to help clear out buildup, control oil, and reduce inflammation.

Unlike AHAs (alpha hydroxy acids), salicylic acid is oil-soluble. This allows it to penetrate into pores which makes it especially effective for treating blackheads and preventing future breakouts.

Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.

There are two forms of panthenol: D and L.

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

• Humectant, drawing moisture into the skin
• Emollient, helping to soften skin
• Solvent, dispersing and stabilizing formulas
• Preservative booster, enhancing the antimicrobial activity of other preservatives 

Centella Asiatica Extract (Centella) is derived from an herb native to Southeast Asia. It is famous for its anti-inflammatory and soothing properties.

Centella is rich in antioxidants and amino acids, such as Madecassic Acid and Asiaticoside.

We don't have a description for Ecklonia Cava Extract yet.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Hydroxypropyl Bispalmitamide MEA is a synthetic molecule designed to mimic ceramides. Ceramides moisturize and strengthen the skin barrier.

This ingredient is claimed to be as effective as Ceramide 3, but with the added benefits of a lower melting point. This makes it easier to work with in formulations at a more affordable price.

Hizikia fusiforme extract comes from the brown seaweed known as hijiki. It has skin conditioning properties.

Hijiki is rich in minerals and polysaccharides, making it a great moisturizer.

We don't have a description for Sargassum Fulvellum Extract yet.

Undaria Pinnatifida Extract comes from a kelp native to the northern Pacific Ocean. It is more commonly known as "wakame".

This kelp contains fatty acids, sodium, calcium, iodine, thiamine, and niacin. Studies show a polysaccharide known as fucoidan exhibits strong antioxidant activities. Fucoidan can be found in the cell walls of many species of brown seaweed.

Aminomethyl Propanol is used to adjust the pH of products. It is also used as a base to create other organic compounds. Having a balanced pH is important for protecting your skin.

Aminomethyl propanol is safe to use in cosmetics up to 1%. It is soluble in water.

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.

The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.

Glycine is the smallest amino acid and a key building block of collagen. It's part if your skin's Natural Moisturizing Factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.

A study from 2022 found that an amino acid complex featuring taurine, arginine, and glycine significantly reduced skin irritation, improved redness, and accelerated the skin repair process.

Serine is a non-essential amino acid (your body makes it on its own!). It is a major player in your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.

Serine is one of your NMF's most abundant components that works as a skin-identical humectant. Its hydroxyl group grabs onto water molecules to boost hydration without any heaviness or occlusion.

Glutamic Acid is an amino acid that is found in all living organisms. Our bodies use this to help nerve cells in the brain communicate with other cells.

In cosmetics, glutamic acid is a famous humectant. It draws water from the air to your skin, keeping your skin hydrated (like hyaluronic acid).

We don't have a description for Codium Fragile Extract yet.

Aspartic 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.

We don't have a description for Leucine yet.

Alanine is an amino acid and is already found in the human body. Our skin uses alanine to build collagen, elastin, and keratin.

Lysine is an essential amino acid (your body cannot make it on its own). It has skin conditioning properties and one of the key players in collagen synthesis.

When your body creates collagen, lysine is basically the glue that holds everything together. It helps collagen fibers lock into each other and stay strong, with vitamin C being its trusty sidekick. Without enough lysine, this glue gets flimsy and less firm, resulting in less bouncy skin.

Arginine is a semi-essential amino acid. This just means our bodies can product a bit on its own, but sometimes needs a little boost from food sources.

It is a part of your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.

Tyrosine is one of the amino acids used to create protein. It plays a role in melanin production.

A study from 2012 found tyrosine to show promising results in restoring skin volume.

Phenylalanine is an amino acid. It is a skin soothing and hydrating ingredient. Amino acids play a crucial role in wound healing and skin hydration.

This ingredient is also used to help even out skin tone due to its ability to disrupt the melanin production process.

Valine is an essential amino acid. It is used by our bodies for tissue repair and muscle growth.

An essential amino acid is one in which our bodies cannot naturally produce so we must get them through diet. Foods such as eggs, dairy, red meat, and fish contain valine.

Threonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.

Our skin uses threonine for creating collagen and elastin. Humans are not able to create threonine and must get it through eating foods such as fish, lentils, poultry, sesame seeds, and more.

Proline is a non-essential amino acid, meaning your body can make it on its own. In skincare, it is a skin conditioning ingredient that keeps skin soft and hydrated.

It makes up about 23% of the collagen molecule (collagen is the protein responsible for keeping your skin firm) and is involved in your skin's natural hyaluronic acid production. When applied topically, proline can penetrate the skin fairly well due to its small molecular size.

Isoleucine is an amino acid that helps reinforce our skin barrier. This amino acid plays a role in creating protein for the body.

Fun fact: Isoleucine is found in meat, fish, dairy, legumes, and nuts.

Histidine is a semi-essential amino acid used by our bodies to create protein. It has humectant and skin conditioning properties.

Our bodies use histidine to create filaggrin - filaggrin is a structural protein that the skin uses in maintaining skin barrier.

Methionine is an essential amino acid. It is a conditioning agent and commonly found in both skin and hair products.

This amino acid is a precursor to glutathione, a powerful antioxidant.

Cysteine is an amino acid found in our bodies. It becomes an antioxidant when converted into gluthatione.

Once it becomes gluthatione, it prevents oxidative damage to parts of our cell. Gluthatione has also been shown to protect our skin from UV-B induced damage.

Madecassoside is one of four active compounds found in Centella asiatica and is one of the main reasons Centella is so effective at calming irritated skin and supporting the moisture barrier.

There's a solid body of peer-reviewed research backing Madecassoside for several skin benefits. Studies have found:
