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. Dimethicone 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. Glyceryl 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. Salicylic Acid (also known as beta hydroxy acid or BHA) is a well-known ingredient for treating skin that struggles with acne and clogged pores. It exfoliates both the skin's surface and deep within the pores to help clear out buildup, control oil, and reduce inflammation. Unlike AHAs (alpha hydroxy acids), salicylic acid is oil-soluble. This allows it to penetrate into pores which makes it especially effective for treating blackheads and preventing future breakouts. Salicylic acid is also known for its soothing properties. It has a similar structure to aspirin and can calm inflamed or irritated skin, making it a good option for acne-prone skin that is also sensitive. Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product. It can cause irritation and/or dryness if one's skin already has a com
