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. SD-Alcohol and some numer+letter refers to alcohol (or ethanol) being denaturated with different kind of additives. These additives make sure that the alcohol is poisonous and bad tasting so that nobody drinks their alcohol-loaded toner. 40-B specifically means the additives are denatonium benzoate and t-butyl alcohol. As for Alcohol Denat in skincare, it's a controversial ingredient. It's a great solvent and makes cosmetically elegant, light formulas but at best it's skin-drying, at worst it's skin-barrier damaging. We have written about alcohol way more here. 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 This long-named, polymer molecule (big molecule from repeated subunits) is a helper ingredient that's good at emulsifying and stabilizing oils into water-based formulas. It also acts as a thickening and gelling agent that creates nice, non-sticky and supple textures. It works over a very wide pH range (3-12) and can be used to thicken up low-ph formulas, such as exfoliants. Its recommended used range is 0.3-3%. It’s a polyhydroxy acid (PHA), that is often referred to as next generation AHA It gently lifts off dead skin cells form the skin surface making skin smooth and even In the long term it provides anti-aging benefits, like increased skin thickness and decreased wrinkles (though a tad less than even more proven superstar AHAs) It’s a great moisturizer and even helps to repair impaired skin barrier It’s antioxidant, and does not make your skin more sensitive to the sun It can be used even if your skin is very sensitive, rosacea prone or if you are post cosmetic procedure It's a common little helper ingredient that helps water and oil to mix together. Also, it can help to increase the solubility of some other ingredients in the formula. It's one of the active parts of Chamomile that contains about 30% of bisabolol.
