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.

You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Cetearyl alcohol is an emollient. Emollients help soothe and hydrate the skin by trapping moisture.

Studies show Cetearyl alcohol is non-toxic and non-irritating. The FDA allows products labeled "alcohol-free" to have fatty alcohols.

Due to the fatty acid base, this ingredient may not be Malassezia folliculitis safe.

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.
