Squalane is a popular ingredient in the cosmetic market. It has a structure close to that of sebum, and has an excellent affinity for the hydrolipidic film present on the skin's surface. Non-greasy, it quickly penetrates the epidermis to combat skin dryness. Squalane thus helps the skin to remain hydrated for a longer period of time and reduces tightness sensations specific to dry skin.
According to the literature, squalane has a comedogenicity index equal to 1. As a reminder, a substance is said to be "comedogenic" when it clogs the pores, leading to the formation of comedones (blackheads, pimples). The comedogenicity of an element is evaluated on a scale from 0 to 5.
Note: Even if squalane is non-comedogenic, we do not recommend it for acne-prone, oily and blemish-prone skin. It is rather recommended to take care of dry and dehydrated skins.
