Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Benzoyl Peroxide (BPO) is one of the most studied and widely used acne-fighting ingredients on the market for over five decades.
It works by releasing oxygen into your pores to kill Cutibacterium acne, or the bacteria closely linked to acne breakouts. This bacteria has a hard time surviving in an oxygen-rich environment.
On top of that, BPO has keratolytic properties to help shed dead skin cells and keep pores from getting clogged.
One of the coolest things about BPO is that bacteria do not develop resistance to it the way they can with antibiotics. That's why dermatologists recommend pairing it with topical antibiotics to keep resistance at bay.
BPO is usually available in 2.5%, 5%, and 10% concentrations. Research has shown that 2.5% tends to be just as effective as the higher strengths while being more gentle on the skin.
The FDA has classified BPO as a safe and effective acne treatment. You'll be able to find this ingredient in over-the-counter products in many countries.
Just so you know, BPO is a known mild irritant. It's common to see dryness, peeling, and some redness when you first start using it. This usually goes away as your skin adjusts.
A very small number of people might develop allergic contact dermatitis from it as patch test studies show positive reactions in about 1-5% of patients.
Once BPO is absorbed into the skin, our bodies turn it into benzoic acid and quickly exits in urine. It's also worth noting that BPO will bleach fabrics and hair, so watch your towels and pillowcases!
Learn more about Benzoyl PeroxideCarbomer 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.
Learn more about CarbomerCyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.
Learn more about CyclopentasiloxaneDiazolidinyl Urea is an antimicrobial preservative. It is commonly used to prevent bacterial, yeast, and mold growth.
Diazolidinyl Urea slowly breaks down into formaldehyde, an effective microbe killer but also a known allergen/carcinogen.
Some people who are allergic to imidazolidinyl urea also react to diazolidinyl urea. It ranked as the 14th most common allergen in patch tests from 2005–06.
Safety reviews show that at concentrations under 0.5%, the formaldehyde released remains below the accepted safety limit, making it considered safe for cosmetic use.
Ultimately, its safety depends on individual skin sensitivity and personal comfort with formaldehyde-releasing preservatives.
Learn more about Diazolidinyl UreaDimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.
Learn more about DimethiconeGlyceryl Stearate is made by reacting glycerin with stearic acid (typically sourced from plant oils like palm or coconut). It's an emulsifier, emollient, and mild occlusive.
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.
Learn more about Glyceryl StearateMethylparaben is a preservative and is a paraben. It is used to prevent the growth of fungus, mold, and other harmful bacteria. Parabens are chemicals used as preservatives in both cosmetics and food.
Methylparaben can be synthetically created. It can also be found naturally in some fruits, such as blueberries.
Oftentimes, Methylparaben is combined with other parabens to help increase the shelf life.
The safety of Methylparaben is currently being studied. While ongoing studies are looking into the safety of parabens, the results have been very mixed. Some studies have not found Methylparaben to be harmful.
Learn more about MethylparabenPropylene Glycol is a synthetic, colorless, odorless liquid that has been a staple in cosmetics for decades. It is a skin conditioning agent, humectant, and solvent.
As a humectant, it draw water to the skin to reduce flaking and restore suppleness. It's also a solvent that helps dissolve other actives and keeps formulas stable across temperature changes.
The CIR Expert Panel has confirmed this ingredient to be nontoxic and clinical studies show no sensitization at cosmetic use concentrations.
True allergic reactions are quite rare: a 15-year retrospective study of 6,751 patients found only 0.31% had a positive reaction (and less than half were considered clinically relevant).
It seemed that when sensitization does occur, it's most commonly linked to topical medication (like corticosteroids) and not cosmetics. Allergic contact dermatitis also appears largely limited to individuals with underlying skin conditions.
Overall, propylene glycol is a well-studied ingredient that most people can tolerate without issue.
Learn more about Propylene GlycolPropylparaben is a preservative and is a paraben with antifungal and antimicrobial properties.
This ingredient can be naturally found in plants and insects, but most of it is synthetically manufactured for human use. In cosmetics, it is usually created by reacting para-aminobenzoic acid and propanol (an alcohol).
You can usually find this ingredient in water-based products.
Parabens have come under controversy due to the claim they are hormone disruptors. Studies show conflicting results. We recommend speaking with a professional if you have any concerns.
Propylparaben is commonly found in food, medicine, and cosmetics.
Learn more about PropylparabenWater. 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!
