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. Works best between a concentration of 5-20% Boosts the skin’s own collagen production Fades pigmentation and brown spots If used under sunscreen it boosts its UV protection Extremely unstable and oxidizes very easily in presence of light or air Stable in solutions with water only if pH is less than 3.5 or in waterless formulations Vit E + C work in synergy and provide superb photoprotection Ferulic acid doubles the photoprotection effect of Vit C+E and helps to stabilize Vit C Potent Vit. C serums might cause a slight tingling on sensitive 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 nice odorless liquid used mainly as a superior solubilizer and efficacy booster for cosmetic active ingredients such as skincare bigshot vitamin C, self-tanning active DHA or the anti-acne gold standard, benzoyl peroxide. Other than that it can also be used in hair care products where it gives a longer-lasting and more uniform coloring. According to a manufacturer, it might even prevent the formation of split ends. 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 helper ingredient that usually comes to the formula coupled with PEG-40 Hydrogenated Castor Oil. The two together work as surfactants and oil solubilizers.
