La Roche-Posay Effaclar Purifying Foaming Gel Face Cleanser for Oily Skin

Coco-Betaine is the natural version of Cocamidopropyl Betaine. It is often derived from coconuts.

Coco-Betaine is a surfactant, meaning it helps remove dirt and oil from the skin.

Hexylene Glycol is a surfactant. Glycols are a class of alcohols. Hexylene Glycol is a surfactant and emulsifier.

As a surfactant, Hexylene Glycol helps gather dirt and oil on your skin to be washed away.

As an emulsifier, Hexylene Glycol helps keep water and oil together. This prevents them from separating in a product. Hexylene Glycol also thins out the texture of a product by lessening viscosity.

Hexylene Glycol has a small molecular weight.

Chances are, you eat sodium chloride every day. Sodium Chloride is also known as table salt. In skincare, sodium chloride plays many roles.

Sodium Chloride helps make product thicker. It also prevents ingredients from separating.

In some products, sodium chloride may be an abrasive, or exfoliator.

Peg-120 Methyl Glucose Dioleate is used to improve texture and stability of a product. It is sugar based.

Peg-120 Methyl Glucose Dioleate helps thicken a product. Once applied, it also creates a thin film to trap moisture in. This helps keep your skin hydrated.

Peg-120 Methyl Glucose Dioleate is the polyethylene glycol ether of the diester of oleic acid and methylglucose. The 120 represents an average of 120 moles of ethylene oxide.

There is limited research on this ingredient, although it is considered safe to use in skincare products.

Zinc PCA (or "zinc salt") differs slightly from zinc itself. PCA stands for pyrrolidone carboxylic acid. However, Zinc PCA comes from zinc.

It can help reduce redness, regulate sebum, and promote the general healing process of the skin.

Zinc PCA tends to be especially useful for those with oily, acne-prone skin. It's certainly an ingredient worth trying out!

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.

Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.

"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!). A small amount is used in formulas to adjust the pH of products. In higher concentrations, it can exfoliate skin.

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 look more even.

Sodium Benzoate is a preservative used in both cosmetic and food products.

Sodium Benzoate is the salt of benzoic acid. Benzoic acid is found naturally in common foods such as cinnamon, tomatoes, berries, apples, honey, mushrooms, and more.

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.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

Caprylyl Glycol is a humectant, meaning it retains 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.

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.

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. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Products use parfum often to give products a scent or cover up smells of different ingredients.

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.
