The lips have no sebaceous glands and have a much thinner stratum corneum than the rest of the face. It means that they don't produce the fatty film that holds water elsewhere, and that they lose humidity much more quickly: this is the physical reason why they crack first in the cold and wind. A lip stick does not hydrate in the sense of adding water, it works in the other direction: it puts on the film that the lips cannot do on their own.
Here that film is built almost entirely with vegetable oils and butters. At the top of the list iscastor oil, which is a classic in lip products because it is viscous and stays where it is placed; then they arrive jojoba, shea butter, avocado, cocoa butter, apricot, olive e sunflower. The structure is given by the waxes: candelilla, beeswax e carnauba they are what holds the dough up and regulates its hardness.
At the end are the details that tell the intention of the formula. The tocopherol it is vitamin E and protects fats from rancidity; I squalene and the beta-sitosterol they are molecules that the skin also produces on its own; the silica and the titanium dioxide they turn off the shine, and that's why the film is invisible instead of shiny. The formula has no perfume: there is only theethyl vanillin, which gives the vanilla note.
