Ingredients higher up in an ingredient list are typically present in a larger amount. 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 Oil is a plant-derived oil from soybean seeds. Like other oils, it is rich in essential fatty acids (mostly linoleic and oleic) that support skin hydration and barrier function. The fatty acids are able to integrate into the lipid matrix of the stratum corneum to help soften skin and reduce water loss. On top of that, soybean oil is rich in vitamins like vitamin E, a potent antioxidant. Research on soybean's active components also point to anti-inflammatory, collagen-stimulating, antioxidant activity, and protection against UV-induced oxidative damage. Most of this research applies to the broader soybean plant and not just the oil fraction alone. This ingredient may not be fungal acne safe due to the oleic acid content. Glycine Soja Seed Extract comes from the seed of the wild soybean plant. Wild soybean extract contains fatty acids (linoleic, oleic, linolenic), vitamin E, and antioxidants. The wild soybean contains soyasaponins, a bioactive compound. Soyasaponins have inflammatory, antimutagenic, anticarcinogenic, antimicrobial properties. Soyasaponin has also been found to inhibit the melanin-creation process. Two powerful components found in the wild soybean include genistein and diadzein. These two isoflavones are potent antioxidants with anti-inflammatory properties. Genistein in particular has been found to prevent redness caused by UV exposure. One study from South Korea found wild soybean extract to help promote hair growth at the cellular level. The wild soybean plant is a cousin to the famous soybean that gives us tofu, soy milk, and soy sauce. Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!). It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome. On a cellular level, it disrupts the cell membranes of microbes by poking holes that
