Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Humectant, Skin Conditioning

Diglycerin is a humectant. It is derived from glycerin, which is naturally found in your skin.

As a humectant, it helps draw moisture to the skin from the air.

Chelating

EDTA is a chelating agent. This is just a fancy way of saying it grabs onto metal ions and holds them so they don't cause trouble.

Trace metals like iron, copper, and calcium sneak into products through water and raw materials. These metals make oils go rancid, cause color and texture changes, and stop preservatives and cleansers from doing their job properly.

EDTA locks them up so it's a neat little background helper ingredient.

Typical use is under 2% but numbers as high as 10-25% have been reported in hair color products.

The Cosmetic Ingredient Review panel looked at the whole family and concluded they're safe as used. At cosmetic concentrations, they have not been found to be skin irritants or sensitizers.

Clinical testing has found no absorption through skin so the scary-sounding oral toxicity numbers from animal studies aren't relevant to a face cream.

One real formulation note: this ingredient is a penetration enhancer so it can slightly increase how much of the other ingredients get through (though this is more of a thing for formulators to work around).

Allergy is genuinely rare; there are a handful of case reports so be sure to avoid if you're patch test positive to EDTA.

Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.

Topically, glycerin does several things at once:

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Hydrolyzed Hyaluronic Acid is hyaluronic acid (HA) that is broken down into lower molecular weight fragments.

It's a humectant that pulls and holds water in the skin to help with hydration, plumpness, and reduce transepidermal water loss.

Because hydrolyzed hyaluronic acid is smaller in size, it can slip past your outermost layer of skin more easily than full-sized HA.

Most formulations will combine all sizes to get the best of both worlds.

Typical usage levels range from 0.01-1%. Any percentage higher than 2% might become goopy and tacky.

This ingredient is an emulsifier that keeps the oily and watery parts of a formula blended together. Its real party trick is making thin, flowable, and very stable emulsions.

Typical use sits around 2-4% (a bit higher for sunscreens and foundations).

The Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe in cosmetics and noted the large molecules aren't likely to be absorbed into skin.

Because it carries a fatty-acid ester component (stearic acid), it may not be fungal acne safe.

Skin Conditioning, Solvent

Pentylene Glycol (1,2-pentanediol) is a multitasking little diol with three main roles in a formula:

Research on alkanediols (the family pentylene glycol belongs to) show they work by disrupting microbial cell membranes. This disruption helps the primary preservative system in a product work more effectively at lower doses.

On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations.

Typical use levels in a formula run about 1-5%.

Humectant, Skin Conditioning

Sodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity.

In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface.

Interestingly, the size of the molecule affects its behavior:

Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.

Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.

You'll typically see concentrations between 0.1-2% for this ingredient.
