Rilastil Aqua Moisturizing Mask Ingredients Explained

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.

Propylene Glycol is an odorless, colorless liquid. As a humectant, it helps skin retain moisture. It also aids in delivering active ingredients.

Another role of this ingredient is preventing a product from melting or freezing. Propylene glycol also adds antimicrobrial properties to a product, elongating product lifespan.

Paraffin is a solid created from petroleum. The term 'paraffin' can also refer to either petroleum Jelly or mineral oil.

It has natural occlusive properties which can worsen oily skin. Due to its petrolatum base, this ingredient is not fungal-acne safe.

Squalane is an emollient that helps the skin hold onto moisture. It's an oily liquid that occurs naturally in certain types of fish and plant oils.

Because squalane boosts hydration in the skin, it also comes with plenty of benefits: it is an antioxidant and can help fight free radicals and skin damage. Squalane is also found to have a detoxifying effect when applied.

Persea Gratissima Oil is made by pressing dehydrated avocado fruit from the tree Persea gratissima, Lauraceae.

Avocado Oil has antioxidant properties. Antioxidants help fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

Algin is brown algae. Algae is an informal term for a group of aquatic organisms that can photosynthesize. It is estimated there are at least 30,000 types of Algae.

Algae contains antioxidants. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

Triethanolamine is an emulsifier and pH adjuster. It is created using ethylene oxide and ammonia. This gives Triethanolamine a nitrogen core and a similar scent to ammonia.

As an emulsifier, it prevents ingredients from separating and enhances texture by adding volume to a product.

Cetyl Palmitate is a wax-like substance.

It comes from palmitic acid and palmityl alcohol. Cetyl Palmitate may not be safe for Malassezia folliculitis, or fungal-acne.

Oenothera Biennis Oil is the fixed oil derived from the seeds of the Evening Primrose.

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.

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.

Xylitol is a humectant and prebiotic. It can help with dry skin.

In studies, xylitol has been shown to improve dry skin. It decreased transepidermal water loss, or when water passes through the skin and evaporates. Xylitol also showed to help improve the biomechanical properties of the skin barrier.

Sodium Lauroyl Lactylate is the lauric acid sodium salt of lactyl lactate.

Sodium Lauroyl Lactylate is an emulsifier and surfactant.

Ceramide NP is a type of ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Ceramide AP is a type of Ceramide.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. Having a strong skin barrier leads to more firm and hydrated skin.

Ceramide EOP is a type of Ceramide. EOP stands for a linked Ester fatty acid, a linked Omega hydroxy fatty acid, and the Phytosphingosine base.

Ceramides are intercellular lipids naturally found in our skin that bonds dead skin cells together to create a barrier. They are known for their ability to hold water and thus are a great ingredient for dry skin.

Olus oil is derived from vegetable oils. It is a blend of triglycerides. Triglycerides are a type of fat that circulate in your blood. The majority of Olus Oil is from rapeseed oil.

Phytosphingosine is already present in our skin. On our skin, it is a building block for ceramides.

Cholesterol is a class of organic molecules called lipids. It helps hydrate your skin and is essential to having a healthy skin barrier.

Our skin naturally contains cholesterol in the outermost layer. Besides cholesterol, it also contains ceramides and fatty acids. Cholesterol makes up about 1/4 of your skin's outer layer and barrier. Your skin barrier is responsible for keeping allergens and microbes out. Having a healthy skin barrier is also responsible for keeping your skin firm and plump.

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.

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.

Potassium Sorbate is a preservative used to prevent yeast and mold in products. It is commonly found in both cosmetic and food products.

Potassium sorbate is potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.

Sodium Methylparaben is a preservative and is a paraben.

Sodium Propylparaben is a preservative and is a paraben.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and microbial growth. By itself, it has a scent that is similar to that of a rose.
