La Roche-Posay Hydraphase HA Rich Hyaluronic Acid Face Cream Ingredients Explained

Butyrospermum Parkii Butter is a plant lipid from the fruit of the Shea Tree. It is an effective skin hydrator and emollient.

Emollients help soothe and soften your skin. It does this by creating a protective film on your skin. This barrier helps trap moisture and keeps your skin hydrated. Emollients may be effective at treating dry or itchy skin.

We don't have a description for Lauroyl Lysine.

Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.

Cetyl Alcohol is not related to SD alcohol, denatured alcohol, or ethyl alcohol. The FDA allows products labeled "alcohol-free" to have fatty alcohols.

Urea is also called carbamide and is the diamide of carbonic acid. In cosmetics, urea is used to hydrate the skin. It also provides exfoliation in higher concentrations.

As a humectant, urea helps draw moisture from the air and from deep within the skin. This helps hydrate your skin. Studies show urea is an effective moisturizer for dry skin conditions. 40% urea is typical in medications for treating eczema and other skin conditions.

Peg-100 Stearate is an emollient and emulsifier. PEGS are a hydrophilic polyether compound . There are 100 ethylene oxide monomers in Peg-100 Stearate. Peg-100 Stearate is polyethylene glycol ester of stearic acid.

Peg-100 Stearate helps keep skin soft by trapping moisture in. It helps prevent oil and water from separating in a product. By binding oil and water, it helps remove dirt and oil to be rinsed away.

Glyceryl Stearate is a mix of glycerin and stearic acid.

Glyceryl Stearate is used to stabilize the mixing of water and oil ingredients. By preventing these ingredients from separating, it can help elongate shelf life. It can also help thicken the product's texture.

Cera alba is beeswax, or the wax used by bees to make honeycombs. It is a texture-enhancer and emollient. A study from 2003 found beeswax to be a stronger emollient than ingredients such as petroleum jelly.

As an emollient, beeswax helps hydrate the skin by creating a barrier on top. This barrier traps moisture in.

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.

Stearic Acid is a fatty acid. It is an emollient, emulsifier, and texture enhancer.

As an emollient, stearic acid helps soften skin. It aids the skin's protective barrier by preventing water loss. It also provides a gentle cleansing effect without stripping away natural oils.

Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.

Carbomer is commonly found in many types of cosmetics products. It is found to be safe in concentrations up to 15%. However, a high amount of carbomer can cause pilling or balling up of products. Most products contain 1% of less of carbomer.

Glyceryl Acrylate/Acrylic Acid Copolymer is made up of glycerin and polyacrylic acid. It helps hydrate your skin as a humectant.

Humectants draw moisture from the air to your skin.

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Myristic Acid is a saturated fatty acid. It is naturally found in milk fat. Other sources include palm oil, coconut oil, and butter fat.

Myristic Acid is an emulsifer and cleanser. As an emulsifer, it stabilizes a product by preventing ingredients from separating. Myristic Acid helps clean your skin by acting as a surfactant. It tends to gather oil and dirt on your skin to be easily rinsed away.

Palmitic Acid is a fatty acid found in our skin. In cosmetics, it is usually derived from palm oil. It is a cleanser, emollient, and emulsifier.

As an emollient, it helps hydrate the skin. The emulsifying properties keep ingredients together in a product.

Hydrolyzed Hyaluronic Acid is a form of hyaluronic acid. It is created by the hydrolysis of hyaluronic acid with a high molecular weight. Once created, Hydrolyzed Hyaluronic Acid has a low molecular weight.

Low molecular weight HA has been shown to hydrate and increase elasticity of the skin. Increasing elasticity is also associated with reduction of wrinkle depth.

Caprylyl 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.

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

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.

Trisodium Ethylenediamine Disuccinate is used to help stabilize a product.

It is a chelating agent, meaning it helps prevent metal ions from binding to other ingredients. This prevents unwanted reactions in products. Metal ions can come into a product via the water ingredient. They are found in trace amounts and are not known to be harmful.

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.

Polysorbate 60 is used to help stabilize products. It is a surfactant and emulsifier. These properties help keep ingredients together in a product. Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating.

Polysorbate 60 is sorbitol-based and created from the ethoxylation of sorbitan. Ethoxylation is a chemical reaction used to add ethylene oxide. Sorbitan is a the dehydrated version of sorbitol, a sugar found in fruits.

Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate (long name, huh?) is a synthetic antioxidant.

It is used to help stabilize other antioxidants or prevent the color from changing in a product.

Chlorphenesin is a synthetic preservative. It helps protect a product against bacteria in order to extend shelf life. In most cases, Chlorphenesin is paired with other preservatives such as phenoxyethanol and caprylyl glycol.

Chlorphenesin is a biocide. This means it is able to help fight the microorganisms on our skin. It is also able to fight odor-releasing bacteria.

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, 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.
