Ingredients higher up in an ingredient list are typically present in a larger amount. 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. 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. Glycine Soja Sterols are plant-derived fatty alcohols (phytosterols) from soybean. You can think of them like the plant world's version of cholesterol; they're structurally similar enough to slot into your skin's lipid barrier and help it do its job. Phytosterols aid skin barrier recovery by traveling deeper into the skin rather than just sitting on top of it. Once inside, they reduce transepidermal water loss (TEWL) and keep skin feeling soft / supple. Research on phytosterols in keratinocyte and macrophase models has shown meaningful inhibition of pro-inflammatory mediators. This supports their reputation as a calming ingredient for reactive or sensitive skin. Subjects with soy allergies did not show a reaction to phytosterols in safety tests, but it wouldn't hurt to patch test if you do have a soy allergy. Fungal acne: Malassezia uses sterols to build its own cell walls so there's a theoretical concern that it could also make use of sterol ingredients in skincare. Though no study has actually proven this happens with topical products, we err on the side of caution and list this ingredient as not safe for fungal acne. However, i
