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. It’s the second most researched AHA after glycolic acid It gently lifts off dead skin cells to reveal newer, fresher, smoother skin It also has amazing skin hydrating properties In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles Choose a product where you know the concentration and pH value because these two greatly influence effectiveness Don’t forget to use your sunscreen (in any case but especially so next to an AHA product) Propanediol is a natural alternative for the often used and often bad-mouthed propylene glycol. It's produced sustainably from corn sugar and it's Ecocert approved. It's quite a multi-tasker: can be used to improve skin moisturization, as a solvent, to boost preservative efficacy or to influence the sensory properties of the end formula. 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 The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right. For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed. BTW, lye is not something new. It was already used by ancient Egyptians to help oil and fat magically turn into something else. Can you guess what? Yes, it’s soap. It still often shows up in the ingredient list of soaps and other cleansers. Sodium hydroxide in itself is a potent skin irritant, but once it's reacted (as it is usually in skin care products, like exfoliants) it is totally harmless. A helper ingredient that usually comes to the formula coupled with PEG-40 Hydrogenated Castor Oil. The two together work as surfactants and oil solubilizers. It's a non-sticky duo that works at low concentration and is often used to solubilize fragrance components into water-based formulas. It’s the - sodium form - cousin of the famous NMF, hyaluron what‑it‑does exfoliant | moisturizer/humectant | buffering solvent | moisturizer/humectant skin-identical ingredient | moisturizer/humectant irritancy, com. emulsifying | surfactant/cleansing
