Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Carbomer is a high-molecular weight polymer of acrylic acid. It is used to form gels and thicken formulas.
Due to its large molecular size, carbomer has minimal skin penetration and is considered an inert ingredient.
A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.

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.

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 The rating of 0 is a correction of outdated science.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.

Its only job is to keep your products from going bad.
It works by disrupting microbial cell membranes and enzymes, and is a broad-spectrum protector that works exceptionally well against molds, yeasts, and gram-positive bacteria.
You'll likely see it paired with methylparaben to cover the full range (including gram-negative bacteria).
This ingredient is effective at low concentrations (~0.2-0.5%) and stable across a wide pH range (4.5-7.5 pH). It's effectiveness drops off above pH 8 and it can lose potency when combined with non-ionic surfactants like polysorbate 80 due to micellization.
The regulatory bodies have concluded this ingredient to be safe as used in cosmetics. The EU has capped it at 0.14% and combined parabens are not to exceed 0.8%.
While parabens do cross the stratum corneum, only about 1% remains for absorption into the body. This is because most of it is metabolized within living skin.

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.

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. If you see this, drink a glass of water. Remember to stay hydrated!
