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 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 Butylene glycol, or let’s just call it BG, is a multi-tasking colorless, syrupy liquid. It’s a great pick for creating a nice feeling product. BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin. It’s an ingredient whose safety hasn’t been questioned so far by anyone (at least not that we know about). BG is approved by Ecocert and is also used enthusiastically in natural products. BTW, it’s also a food additive. 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 We don't have description for this ingredient yet. It’s the - sodium form - cousin of the famous NMF, hyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water. As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably.
