Skin care is becoming increasingly ingredient-focused lately, largely due to bloggers and corners of the internet like the SkincareAddiciton Subreddit. Rather than blindly picking products because a Youtuber promises it’s the key to glowy skin — skin-care enthusiasts are patch-testing, researching and documenting their experiences like never before. This has thrust ingredients like hyaluronic acid and vitamin C into the spotlight, and turned little known oils into must-haves for your skin-care routine. One such example is squalane, an oil similar to squalene — a fatty molecule that’s already present in our skin. Squalene can also be found in plants and shark livers but is unstable in its natural state and quickly goes bad. To stabilize it for our skin-care routines, squalene is hydrogenated and becomes squalane, which can be used on its own or added to formulations. Squalane is also similar to our skin’s cell membrane, meaning it absorbs quickly, and because it’s already present in the skin, it rarely causes breakouts or clogs pores. It’s also incredibly lightweight and non-greasy, making it an ideal pre-makeup base. Convinced you need it in your routine?
