Ingredients Explained

These ingredients are found in both products.

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

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.

Ethylhexyl Triazone (aka Octyl Triazone) is an oil-soluble organic UVB filter. It has peak absorption around 314 nm, right in the middle of the UVB range.

This ingredient is described as one of the most effective UVB filters available and small concentrations are enough to deliver a high SPF thanks to its strong UV absorbing power.

Formulators love it for its stability; its ability to filter UV stays practically unchanged even under intense radiation and it can also help boost the photostability of less stable filters like avobenzone.

It's also a great pick for water resistant products because it's insoluble in water and has a good affinity for keratin.

Because it's a big, heavy molecule, the European Scientific Committee has found to to have very low dermal penetration and negative results for allergenicity.

In vitro testing also showed a low absorption rate and clean results on irritation.

Typical use levels are 1-5% with 5% being the maximum in the EU, Japan, and other markets that allow it. However, this ingredient is not approved yet in the US or Canada.

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.

Poly C10-30 Alkyl Acrylate is a synthetic polymer. It's a long chain built from acrylic acid units and each unit carries a fatty "tail" derived form a C10-30 alcohol.

Those oil-loving tails allow this ingredient to thicken oil phases, hold emulsions together, and cuts the tacky/greasy feel of heavy formulas.

Typical use levels sit around 0.1-3%, with 0.3-3% more common in leave-on emulsions.

This ingredient was reviewed as part of a group of 126 acrylates and concluded to be safe by the Cosmetic Ingredient Review Expert Panel.

Though acrylate contact allergy is real and well-documented, allergy risk is quite low. The cases of documented contact allergy are caused by unreacted monomers (more commonly found in gel nails, dental resins, and adhesives).

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

Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.

On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.

Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.

  6. 06Dipropylene Glycol is a synthetically created humectant, stabilizer, and solvent.
  7. 07This ingredient helps:
  8. 08Dipropylene glycol is technically an alcohol, but it belongs to the glycol family (often considered part of the ‘good’ alcohols). This means it is hydrating and gentle on skin unlike drying solvent alcohols like denatured alcohol.
  9. 09As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.
  10. 10Studies show Dipropylene Glycol is considered safe to use in skincare.

  19. 19And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin.
  20. 20You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this.
