The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. Expand to read more Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying. One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time. A super commonly used 5 unit long, cyclic structured silicone that is water-thin and does not stay on the skin but evaporates from it (called volatile silicone). Similar to other silicones, it gives skin and hair a silky, smooth feel. It's often combined with the non-volatile (i.e. stays on the skin) dimethicone as the two together form a water-resistant, breathable protective barrier on the skin without a negative tacky feel. A natural moisturizer that’s also in our skin A super common, safe, effective and cheap molecule used for more than 50 years Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40% High-glycerin moisturizers are awesome for treating severely dry skin A multi-functional skincare superstar with several proven benefits for the skin Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration Fades brown spots alone or in combination with amino sugar, acetyl glucosamine Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%. It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols. Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating and are totally ok for the skin. Isosorbide Dicaprylate (IDC) is a smart, oil-loving skin hydrator and barrier builder molecule. It works synergistically with glycerin as it up-regulates Aquaporin 3 (AQP3), an important transmembrane protein that tr what‑it‑does emollient | solvent skin-identical ingredient | moisturizer/humectant irritancy, com. cell-communicating ingredient | skin brightening | anti-acne | moisturizer/humectant emollient | viscosity controlling | emulsifying | surfactant/cleansing cell-communicating ingredient | moisturizer/humectant emollient | emulsifying surfactant/cleansing | emulsifying soothing | moisturizer/humectant emulsifying | surfactant/cleansing moisturizer/humectant | solvent moisturizer/humectant | emollient solvent | emulsifying | perfuming | surfactant/cleansing solvent | moisturizer/humectant skin-identical ingredient | antioxidant | emollient chelating | buffering antioxidant | soothing | emollient | abrasive/scrub surfactant/cleansing
