Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!

Glycol Distearate serves as a pearlizing or opacifying agent in cosmetic products.
It's often included in cleansers and haircare products to give them a lustrous or shimmering appearance.
It is derived from stearic acid, a natural fatty acid commonly found in vegetable oils and animal fats.
Glycol Distearate isn't fungal acne safe.

Cocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine. Dimethylaminopropylamine is a diamine, an amine with two amino groups.
Cocamidopropyl Betaine is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.
Being created from coconut oil means Cocamidopropyl Betaine is hydrating for the skin.
While Cocamidopropyl Betaine was believed to be an allergen, a study from 2012 disproved this. It found two compounds in unpure Cocamidopropyl Betaine to be the irritants: aminoamide and 3-dimethylaminopropylamine. High-grade and pure Cocamidopropyl Betaine did not induce allergic reactions during this study.

Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.
Dimethicone has been found increase absorption in skin, boosting the benefits of other ingredients. While there is concern for the safety of dimethicone, the levels used in skincare are safe for use.

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.
