Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Aroma refers to an ingredient, or mixture of ingredients, that impart or mask a flavor.
The name is slightly confusing. This is because INCI associates aroma with flavor instead of smell.
Here is the official definition from the The International Cosmetic Ingredient Dictionary and Handbook:
“Aroma is a term for ingredient labeling used to identify that a product contains a material or combination of materials normally added to a cosmetic to produce or to mask a particular flavor.”
INCI shows the only purpose of aroma to be "flavouring".
However, due to regulation differences, some companies may use aroma in place of parfum.
In Canada, this ingredient only has to be listed in concentrations above 1%.

Due to its large molecular size, this ingredient is not absorbed into the skin.
This is a synthetic polymer used to thicken formulas, improve texture, and enhance spreadability.
Due to its large molecule size, this ingredient does not penetrate the skin and is considered well-tolerated.
Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.
In one study, Hydrogenated Polyisobutene showed better skin hydration levels than Caprylic/Capric Triglyceride. As an emollient, it helps keep your skin soft and hydrated by trapping moisture in.
Hydrogenated Polyisobutene is often used as a mineral oil replacement.

It is one of the two most-used fragrance ingredients in cosmetics and added purely for smell. Since it's not used for a skin benefit, there's no "effective dose". Concentration depends on the fragrance load of the product.
The EU requires it to be named on the label above 0.001% in leave-on and 0.01% in rinse-off products.
Fresh linalool is a weak sensitizer but air exposure turns some of it into hydroperoxides, which are strong sensitizers. Those oxidation products are the actual allergy concern.
Patch-test clinics see positive reactions to linalool hydroperoxides in about 4% to 12% of dermatitis patients depending on country and test concentration.
Resassuringly, one analytical study found hydroperoxide levels in real fragranced products to be orders of magnitude below what induced sensitization in animal studies with no evidence of oxidation building up during normal storage.
The practical takeaway is that linalool is fine for most people but worth avoiding if you have a confirmed fragrance contact allergy or a badly compromised barrier.
Products stored a long time after opening are also the high-risk scenario since that is when oxidation happens.
The scent of linalool is described as floral, spicy tropical, and citrus-like.

It is:
You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.
This ingredient is typically used at levels between 2-20%.
Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.
Paraffinum Liquidum is a highly-refined cosmetic-grade mineral oil. It is also known as liquid paraffin.
Despite its controversial reputation, the science is pretty clear: it's one of the most well-studied and effective moisturizing ingredients out there.
As an occlusive, it forms a protective layer on the skin that locks in moisture and prevents transepidermal water loss (TEWL). This makes it especially great for compromised skin barriers.
The "it clogs your pores" myth has been around for decades; a study found that industrial-grade mineral oil may be comedogenic but cosmetic-grade mineral oil is not (these two are very, very different).
A 2017 review concluded that cosmetic use of mineral oils and waxes does not present a risk to consumers due to absorption.
Mineral oil got a bad rap from the old rabbit ear studies. When tested on actual human skin, cosmetic-grade mineral oil showed no comedogenic activity. The rating of 0 is a correction of outdated science.
Mineral oil is an inert substance with no fatty acids so there's nothing to feed Malassezia. This ingredient is fungal acne safe.

This ingredient comes from isostearic acid, a saturated fatty acid. It is a synthetic ingredient.
We don't have a description for Triisostearyl Citrate yet.
