Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Caprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss.
Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that it is very stable, resistant to oxidation, and unlikely to go rancid.
In practice, that translates to a long shelf life and a consistently elegant skin feel.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns.
Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.
This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.
This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.

Emulsifiers help ingredients like oil and water stay mixed so your formula stays nicely blended and uniform in texture.
This ingredient is typically used in concentrations between 1-10%. Studies have found it to be non-sensitizing, non-phototoxic, and non-photoallergenic.
A close cousin of this ingredient is Glyceryl Stearate SE ("self-emulsifying"). This just has a small amount of sodium or potassium stearate added so it can emulsify without a co-emulsifier.
Since this ingredient is an ester of a C18 fatty acid, it may not be fungal acne safe. The Malassezia yeast can potentially metabolize within the C11-C24 range.
Fun fact: The human body also creates Glyceryl Stearate naturally.

This ingredient is made by joining three building blocks: PEG, Isostearic Acid and glycerin. The PEG gives it the oil-and-water blending power.
This ingredient has been found safe for use in cosmetics and broader PEG family testing shows minimal irritation/sensitization. The molecule's large size also means it isn't expected to penetrate skin to any meaningful degree.
Fungal acne note: This ingredient may not be fungal acne safe due to isostearic acid (C18). Isostearic acid falls into the C11-24 range that Malassezia can feed on.

It's mostly a behind-the-scenes texture enhancer that's especially good at "thixotropic" thing where the product stays thick but applies nicely.
Because of its structure, it also acts as a mild skin conditioning emollient that helps soften skin while preventing moisture loss.
Safety studies show it to be safe and non-irritation in clinical tests. It's typically used in concentrations up to 5%.
Since its an ester of a C18 fatty acid, it falls into the C11-24 range that Malassezia can potentially feed on. This makes it not fungal-acne safe.
