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. 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. It’s naturally in our skin and behaves there like a sponge It can bind up to 1000 times its own weight in water It is a big molecule from repeated subunits (polymer) so different molecular weight versions exist (unfortunately there is no way to determine MW from INCI list only) High-molecular-weight-HA (>500 kDa) is an excellent surface hydrator, skin protectant and can act as an osmotic pump helping water-soluble actives to penetrate deeper into the skin Low-molecular-weight-HA (< 500 kDa) can hydrate the skin somewhat deeper though it is still a big molecule and works mainly in the epidermis (outer layer of the skin) Low-molecular-weight-HA might also help the skin to repair itself by increasing its self-defense (~ 200kDa used in the study) Ultra-low-molecular-weight-HA (<50kDa) is a controversial ingredient and might work as a pro-inflammatory signal molecule 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 A helper ingredient that helps to make the products stay nice longer, aka preservative. It works mainly against fungi. It’s pH dependent and works best at acidic pH levels (3-5). It’s not strong enough to be used in itself so it’s always combined with something else, often with potassium sorbate. what‑it‑does solvent | moisturizer/humectant skin-identical ingredient | moisturizer/humectant exfoliant | chelating
