Science & Benefits

Arachidic Acid is a $C_{20}$ saturated fatty acid. It acts as a structural lipid that helps restore the skin's barrier function. It is zero-irritant. While it has a moderate comedogenic rating, it is a 'logic hero' for those with a compromised barrier; it provides the structural density needed to prevent transepidermal water loss (TEWL) without the 'greasy' or 'sticky' feel of liquid oils.
