- May play a role in helping skin feel smoother
Octadecenedioic Acid Description
Octadecenedioic acid is a carboxylic acid, which refers to a group of acids whose carbon and oxygen atoms are double bonded to a single-bonded hydrogen-oxygen combination. Carboxylic acids have a wide variety of uses in cosmetics, from smoothing and softening skin to easing redness and providing antimicrobial properties that help keep a cosmetic safe from contaminants.
Back to octadecenedioic acid, which is often referred to the scientific research as 9-octadecenedioic acid: it’s plant-derived (from olives) and studies show it plays a novel role in interrupting excess melanin via binding to enzymatic receptor sites on skin’s surface that help encourage normal, even skin color.
The recommended usage level for octadecenedioic acid in skin care with the goal of improving dark spots is 2%. Although this is a promising ingredient, it’s rarely used in cosmetics; however, it’s not known to be problematic for skin.
